Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting PoliciesNote 1 - Basis of Presentation and Summary of Significant Accounting Policies Description of Business Uber Technologies, Inc. (“Uber” or “the Company”) was incorporated in Delaware in July 2010, and is headquartered in San Francisco, California. The Company is a technology company that is powering movement in countries around the world, principally in the United States (U.S.) and Canada, Latin America, Europe, the Middle East, and Asia (excluding China and Southeast Asia). The Company’s principal activities are to develop and support proprietary technology applications (“ platform(s) ”) that enable independent providers of ridesharing services (“ Driver Partner(s) ”), Eats meal preparation services (“ Restaurant Partner(s) ”) and Eats meal delivery services (“ Delivery Partner(s) ”), collectively the Company’s “ Partners ,” to transact with “Rider(s)” (for ridesharing services) and “Eater(s)” (for meal preparation and delivery services), collectively defined as “end-user” or “end-users.” Driver Partners provide ridesharing services to Riders through a range of offerings based on vehicle type and/or the number of Riders . Restaurant Partners and Delivery Partners provide meal preparation and delivery services, respectively, to Eaters. In addition, the Company also provides freight transportation services to shippers within the freight industry and leases vehicles to third-parties that may use the vehicles to provide ridesharing or Eats services through the Platforms . Refer to Note 2 - Revenue for further information. The Company has organized its operations into two operating and reportable segments: Core Platform and Other Bets. Core Platform primarily includes the ridesharing and Uber Eats products; while Other Bets primarily includes the Company’s Freight and New Mobility products. In June 2019, the Company announced a number of leadership and organizational changes. The Company is currently evaluating the impact to its operating and reportable segments based on how the businesses will be managed subsequent to the changes. These organizational changes will be effective in the third quarter of 2019. Refer to Note 13 - Segment Information and Geographic Information for further information. Initial Public Offering On May 14, 2019 , the Company closed its initial public offering (“IPO”), in which it issued and sold 180 million shares of its common stock. The price was $45.00 per share. The Company received net proceeds of approximately $8.0 billion from the IPO after deducting underwriting discounts and commissions of $106 million and offering expenses. Upon closing of the IPO: i) all shares of the Company’s outstanding redeemable convertible preferred stock automatically converted into 905 million shares of common stock; ii) holders of the 2021 Convertible Notes and the 2022 Convertible Notes elected to convert all outstanding notes into 94 million shares of common stock; and, iii) an outstanding warrant which became exercisable upon the closing of the IPO was exercised to purchase 0.2 million shares of common stock. In addition, the Company recognized a net gain of $327 million in other income (expense), net in the condensed consolidated statement of operations upon conversion of the 2021 Convertible Notes and the 2022 Convertible Notes during the second quarter of 2019, which consisted of $444 million gain on extinguishment of debt and settlement of derivatives, partially offset by $117 million loss from the change in fair value of embedded derivatives prior to settlement. The extinguishment of debt resulted in the derecognition of the carrying value of the debt balance and settlement of embedded derivatives. Upon the Company’s IPO, the Company recognized $3.6 billion of stock-based compensation expense. Upon the IPO, shares were issued to satisfy the vesting of restricted stock units (“RSUs”) with a performance condition. To meet the related tax withholding requirements, the Company withheld 29 million of the 76 million shares of common stock issued. Based on the IPO public offering price of $45.00 per share, the tax withholding obligation was $1.3 billion . As a result of stock-based compensation expense for vested and unvested RSUs upon the IPO, the Company recorded an additional deferred tax asset of approximately $1.1 billion that is offset by a full valuation allowance. Due to the valuation allowance, no income tax benefit was recognized in income during the three months ended June 30, 2019 . ATG Investment In April 2019, the Company entered into a preferred unit purchase agreement with affiliates of SoftBank Vision Fund (“SoftBank”), Toyota Motor Corporation (“Toyota”), and DENSO Corporation (“DENSO” and together with SoftBank and Toyota, the “ATG Investors”). Pursuant to the preferred unit purchase agreement, the ATG Investors agreed to invest an aggregate of $1.0 billion in a newly formed corporate parent entity for the Company’s Advanced Technologies Group (“ATG”) in exchange for preferred units of ATG collectively representing approximately a 14% ownership interest in ATG on a fully diluted basis. The Company agreed to contribute certain of its subsidiaries and all assets and liabilities primarily related to its autonomous vehicle technologies, (excluding liabilities arising from certain indemnification obligations related to the Levandowski arbitration and any remediation costs associated with certain obligations that may arise as a result of the Waymo settlement), in exchange for common units of ATG representing approximately an 86% ownership interest in ATG on a fully diluted basis. The preferred units held by each of the ATG Investors will receive an annual dividend of 4.5% , which will be payable in cash or accrete to the holder of preferred units, at ATG’s election. The Company and Softbank also agreed to put and call obligations with respect to SoftBank’s preferred units (priced at the greater of (i) cost plus any accrued and unpaid dividends and (ii) the then fair market value of the preferred units) if ATG has not gone public or been sold as of the seventh anniversary of the closing of the transaction. If the Company is a publicly traded company as of the seventh anniversary of the closing of transaction, the Company has the option to satisfy all, or a portion of, its put and call obligations with shares of its common stock and any remainder will be satisfied in cash. If the Committee on Foreign Investment in the United States blocks or unwinds the ATG Collaboration Agreement (described below) or requires mitigation measures that materially and adversely affect the strategic benefits of the ATG Collaboration Agreement, the ATG Investors will each have the right to require ATG to redeem some or all of its preferred units at a price equal to its respective initial investment amount, which redemption(s) may be satisfied in cash or in exchange for shares of the Company’s common stock if a cash redemption would have a material and adverse impact on ATG. In addition to the unit purchase agreement, the Company has entered into a joint collaboration agreement with Toyota, DENSO, and ATG with respect to next-generation self-driving hardware and the development of self-driving vehicles leveraging technology from each of the parties (the “ATG Collaboration Agreement”), which became effective as of the closing of the transaction. Pursuant to the ATG Collaboration Agreement, ATG and Toyota will agree on development plans, and thereafter Toyota will contribute to ATG up to an aggregate of $300 million in cash over six semi-annual installments to fund the ongoing activities contemplated under the ATG Collaboration Agreement. On July 2, 2019, the investment by the ATG Investors in ATG was consummated. Softbank and Toyota are existing investors in the Company. Pending Acquisition of Careem On March 26, 2019, the Company entered into an asset purchase agreement (the “Agreement”) with Careem Inc. (“Careem”). Pursuant to the Agreement, upon the terms and subject to the conditions thereof, Augusta Acquisition B.V., an indirect wholly-owned subsidiary of the Company, will acquire substantially all of the assets and assume substantially all of the liabilities of Careem for consideration of approximately $3.1 billion , subject to certain adjustments. The total consideration will consist of up to approximately $1.7 billion in non-interest-bearing unsecured convertible notes and approximately $1.4 billion in cash. Careem is a Dubai-based company that provides ridesharing, meal delivery, and payment services across the Middle East, North Africa, and Pakistan. The acquisition is subject to applicable competition authority approvals in certain of the countries in which Careem operates. The closing is expected to occur in January 2020. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2018 , included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (“the Securities Act”), on May 13, 2019 (“the Prospectus”). In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. There have been no changes to the Company’s significant accounting policies described in the Prospectus that have had a material impact on the Company’s condensed consolidated financial statements and related notes, except for the adoption of the new accounting standard related to lease accounting. Basis of Consolidation The condensed consolidated financial statements of the Company include the accounts of the Company and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 15 - Variable Interest Entities ("VIEs") for further information. Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, the Company evaluates its estimates, including those related to the incremental borrowing rate (“IBR”) applied in lease accounting, accounts receivable allowances, fair values of investments and other financial instruments, useful lives of amortizable long-lived assets and intangible assets, stock-based compensation, income and non-income taxes, insurance reserves, and contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates. Significant Accounting Policies - Leases The Company accounts for leases in accordance with ASC 842, Leases (“ASC 842”), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The Company adopted ASC 842 along with all subsequent ASU clarifications and improvements that are applicable to the Company, on January 1, 2019, using the modified retrospective transition method and used the effective date as the date of initial application. Consequently, financial information is not updated and the disclosures required under ASC 842 are not provided for dates and periods before January 1, 2019. ASC 842 provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permits the Company not to reassess under ASC 842 its prior conclusions about lease identification, lease classification and initial direct costs. The Company also made a policy election not to separate non-lease components from lease components, therefore, it will account for lease component and the non-lease components as a single lease component. The Company determines if a contract contains a lease based on whether it has the right to obtain substantially all of the economic benefits from the use of an identified asset and whether it has the right to direct the use of an identified asset in exchange for consideration, which relates to an asset which the Company does not own. Right of use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are recognized as the lease liability, adjusted for lease incentives received. Lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s IBR, because the interest rate implicit in most of the Company’s leases is not readily determinable. The IBR is a hypothetical rate based on the Company’s understanding of what its credit rating would be to borrow and resulting interest the Company would pay to borrow an amount equal to the lease payments in a similar economic environment over the lease term on a collateralized basis. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in the Company’s lease liability calculation. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The lease term of operating and finance leases vary from less than a year to 76 years . The Company has leases that include one or more options to extend the lease term for up to 14 years as well as options to terminate the lease within one year. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating leases are included in operating lease right to use assets, operating lease liabilities, current and operating lease liabilities, non-current on the Company’s condensed consolidated balance sheets . Finance leases are included in property and equipment, net, accrued and other current liabilities, and other long-term liabilities on the Company’s condensed consolidated balance sheets . As of June 30, 2019 , less than 15% of the Company’s ROU assets were generated from leased assets outside of the U.S. Cash and Cash Equivalents Cash and cash equivalents as of June 30, 2019 consisted of cash held in checking and savings accounts as well as investments in money market funds and U.S. government securities. The Company considers all highly-liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash includes amounts collected on behalf of, but not yet remitted to Partners, which are included in accrued and other current liabilities on the consolidated balance sheets. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Upon adoption of the new leasing standard on January 1, 2019, the Company recognized ROU assets of $888 million and lease liabilities of $963 million . The Company reassessed the build-to-suit leases that no longer meet the control-based build-to-suit model and derecognized $392 million in build-to-suit assets, $350 million corresponding financing obligation, and recorded $9 million of deferred tax liability. The initial cash contribution to the Mission Bay 3 & 4 joint venture that was previously reported as a defeasance of a build-to-suit financing obligation of $60 million was derecognized by reclassifying it as an increase to the Mission Bay 3 & 4 equity method investment. The $9 million difference between the total derecognized assets and total derecognized liabilities was recorded in the opening balance of accumulated deficit, net of tax, as of January 1, 2019. In July 2017, the FASB issued ASU 2017-11, “Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception” to simplify the accounting for certain instruments with down round features. The amendments require companies to disregard the down round feature when assessing whether the instrument is indexed to its own stock, for purposes of determining liability or equity classification. Further, companies that provide earnings per share (“EPS”) data will adjust the basic EPS calculation for the effect of the feature when triggered and will also recognize the effect of the trigger within equity. The Company adopted this new standard as of January 1, 2019 and applied the changes retrospectively. The adoption of the new standard did not have a material impact on the Company’s condensed consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, “Improvements to Non-Employee Share-Based Payment Accounting,” which expands the scope of Topic 718, to include share-based payments issued to non-employees for goods or services. The new standard supersedes Subtopic 505-50. The Company adopted the new standard effective January 1, 2019 on a modified retrospective basis. The new standard did not have a material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” to require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The standard also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements in ASC 820, “Fair Value Measurement” (“ASC 820”). The new standard is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In October 2018, the FASB issued ASU 2018-17, “Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest and requires organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value MeasurementNote 3 - Fair Value Measurement The Company’s investments on the condensed consolidated balance sheets consisted of the following as of December 31, 2018 and June 30, 2019 (in millions) : As of December 31, 2018 June 30, 2019 Non-marketable equity securities: Didi $ 7,953 $ 7,953 Other 32 94 Debt securities: Grab (1) 2,328 2,334 Other (2) 42 34 Investments $ 10,355 $ 10,415 (1) Recorded at fair value with changes in fair value recorded in other comprehensive income (loss), net of tax. (2) Recorded at fair value with changes in fair value recorded in earnings due to the election of the fair value option of accounting for financial instruments. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In accordance with ASC 820, the Company uses the fair value hierarchy, which prioritizes the inputs used to measure fair value. The hierarchy, as defined below, gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are set forth below: Level 1 Observable inputs such as quoted prices in active markets for identical assets or liabilities. Level 2 Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs other than the quoted prices that are observable either directly or indirectly for the full term of the assets or liabilities. Level 3 Unobservable inputs in which there is little or no market data and that are significant to the fair value of the assets or liabilities. The Company measures its cash equivalents, certain investments, warrants, and derivative financial instruments at fair value. Level 1 instrument valuations are based on quoted market prices of the identical underlying security. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. Level 3 instrument valuations are valued based on unobservable inputs and other estimation techniques due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis based on the three-tier fair value hierarchy (in millions) : As of December 31, 2018 As of June 30, 2019 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial Assets Cash and cash equivalents: Money market funds $ 268 $ — $ — $ 268 $ 6,000 $ — $ — $ 6,000 U.S. government securities — — — — — 1,049 — 1,049 Restricted cash and cash equivalents: Money market funds 1,237 — — 1,237 1,497 — — 1,497 Investments: Debt securities — — 2,370 2,370 — — 2,368 2,368 Total financial assets $ 1,505 $ — $ 2,370 $ 3,875 $ 7,497 $ 1,049 $ 2,368 $ 10,914 Financial Liabilities Accrued and other current liabilities: Other $ — $ — $ 9 $ 9 $ — $ — $ 3 $ 3 Other long-term liabilities: Warrants — — 52 52 — — — — Embedded derivatives — — 2,018 2,018 — — — — Total financial liabilities $ — $ — $ 2,079 $ 2,079 $ — $ — $ 3 $ 3 During the six months ended June 30, 2019 , the Company did not make any transfers between the levels of the fair value hierarchy. The following table summarizes the amortized cost, unrealized gains and losses, and fair value of the Company’s financial assets measured at fair value on a recurring basis as of December 31, 2018 and June 30, 2019 (in millions) : As of December 31, 2018 As of June 30, 2019 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Amortized Cost Unrealized Gains Unrealized Losses Fair Value Cash and cash equivalents: U.S. government securities $ — $ — $ — $ — $ 1,049 $ — $ — $ 1,049 Investments: Debt securities 2,305 65 — 2,370 2,307 61 — 2,368 Total $ 2,305 $ 65 $ — $ 2,370 $ 3,356 $ 61 $ — $ 3,417 The Company’s Level 3 debt securities as of December 31, 2018 and June 30, 2019 primarily consist of redeemable preferred stock investments in privately held companies without readily determinable fair values. Depending on the investee’s financing activity in a reporting period, management’s estimate of fair value may be primarily derived from the investee’s financing transactions, including the issuance of preferred stock to new investors. The price in these transactions generally provides the best indication of the enterprise value of the investee. Additionally, based on the timing, volume, and other characteristics of the transaction, the Company may supplement this information by using other valuation techniques, including the guideline public company approach. The guideline public company approach relies on publicly available market data of comparable companies and uses comparative valuation multiples of the investee’s revenue (actual and forecasted), and therefore, unobservable data primarily consists of short-term revenue projections. Once the fair value of the investee is estimated, an option pricing model (“OPM”) is employed to allocate value to various classes of securities of the investee, including the class owned by the Company. The model involves making key assumptions around the investees’ expected time to liquidity and volatility. An increase or decrease in any of the unobservable inputs in isolation, such as the security price in a significant financing transaction of the investee, could result in a material increase or decrease in the Company’s estimate of fair value. Other key unobservable inputs, including short-term revenue projections, time to liquidity, and volatility are less sensitive to the valuation in the respective reporting periods, as a result of the primary weighting on the investee’s financing transactions during 2018 and 2019. In the future, depending on the weight of evidence and valuation approaches used, these or other inputs may have a more significant impact on the Company’s estimate of fair value. The following table summarizes information about the significant unobservable inputs used in the fair value measurement for the Company’s investment in Grab as of December 31, 2018 and June 30, 2019 : Fair value method Relative weighting Key unobservable input Financing transactions 100% Transaction price per share $6.16 The Company determines realized gains or losses on the sale of equity and debt securities on a specific identification method. The Company did not recognize any other-than-temporary impairment losses during three and six months ended June 30, 2018 and 2019 . The following table summarizes the amortized cost and fair value of the Company’s debt securities with a stated contractual maturity or redemption date as of December 31, 2018 and June 30, 2019 (in millions) : As of December 31, 2018 As of June 30, 2019 Amortized Cost Fair Value Amortized Cost Fair Value Within one year $ — $ — $ 1,049 $ 1,049 One year through five years 2,275 2,328 2,277 2,334 Total $ 2,275 $ 2,328 $ 3,326 $ 3,383 The following table presents a reconciliation of the Company’s financial assets measured and recorded at fair value on a recurring basis as of June 30, 2019 , using significant unobservable inputs (Level 3) (in millions) : Debt Securities Balance as of December 31, 2018 $ 2,370 Total net gains (losses) Included in earnings (8 ) Included in other comprehensive income (loss) 4 Purchases 2 Sales — Settlements — Balance as of June 30, 2019 $ 2,368 The following table presents a reconciliation of the Company’s financial liabilities measured at fair value as of June 30, 2019 using significant unobservable inputs (Level 3), and the change in fair value recorded in other income (expense), net in the condensed consolidated statements of operations (in millions) : Warrants Convertible Debt Embedded Derivative Balance as of December 31, 2018 $ 52 $ 2,018 Vesting of share warrants 1 — Exercise of vested share warrants (53 ) — Change in fair value — (58 ) Settlement of derivative liability — (1,960 ) Balance as of June 30, 2019 $ — $ — Convertible Debt Embedded Derivative Convertible debt embedded derivatives originated from the issuance of the 2021 convertible notes and 2022 convertible notes (collectively the “ Convertible Notes ”) during 2015. Refer to Note 7 - Long-Term Debt and Revolving Credit Arrangements for further information. The fair value of the embedded derivatives was computed as the difference between the estimated value of the Convertible Notes with and without the Qualified Initial Public Offering (“ QIPO ”) Conversion Option (“ QIPO Conversion Option ”). The fair value of the Convertible Notes with and without the QIPO Conversion Option was estimated utilizing a discounted cash flow model to discount the expected payoffs at various potential QIPO dates to the valuation date. The key inputs to the valuation model included the probability of a QIPO occurring at various times, which was estimated to be 100% cumulatively by 2019 and a discount yield that was derived by the credit spread based on the average of the option-adjusted spreads of comparable instruments plus risk-free rates. Fair value measurements are highly sensitive to changes in these inputs; significant changes in these inputs would result in a significantly higher or lower fair value. No value was attributed to other embedded features as they are triggered by events with a remote probability of occurrence. Upon closing of the IPO, holders of the 2021 Convertible Notes and the 2022 Convertible Notes elected to convert all outstanding notes into 94 million shares of common stock. Refer to Note 1 - Basis of Presentation and Summary of Significant Accounting Policies for further information. Warrant Liabilities In February 2016, the Company issued two warrants to an investor advisor to purchase up to 205,034 shares and 820,138 shares of the Company’s Series G redeemable convertible preferred stock at an exercise price of $0.01 per share in exchange for advisory services. The warrants were liability-classified due to the contingent redemption features in the underlying preferred stock and were consequently measured at their fair value of $45 million as of December 31, 2018 . The vested shares were exercised during the first quarter of 2019, and the Company reclassified the $45 million fair value of the vested shares to Series G redeemable convertible preferred stock. Upon closing of the IPO, the Series G redeemable convertible preferred stock were automatically converted to shares of common stock. Assets Measured at Fair Value on a Non-Recurring Basis The Company’s non-financial assets, such as goodwill, intangible assets and property and equipment are adjusted to fair value when an impairment charge is recognized. Such fair value measurements are based predominately on Level 3 inputs. Non-Marketable Equity Securities The Company’s non-marketable equity securities are investments in privately held companies without readily determinable fair values and primarily relate to its investment in Didi. On January 1, 2018, the Company adopted ASU 2016-01, in which the carrying value of its non-marketable equity securities are adjusted based on price changes from observable transactions of identical or similar securities of the same issuer or for impairment (referred to as the measurement alternative). Any changes in carrying value is recorded within other income (expense), net in the condensed consolidated statements of operations . Non-marketable equity securities are classified within Level 3 in the fair value hierarchy because the Company estimates the fair value of these securities based on valuation methods, including the common stock equivalent method, using the transaction price of similar securities issued by the investee adjusted for contractual rights and obligations of the securities it holds. The following is a summary of unrealized gains and losses from remeasurement (referred to as upward or downward adjustments) recorded in other income (expense), net in the condensed consolidated statements of operations , and included as adjustments to the carrying value of non-marketable equity securities held during the three and six months ended June 30, 2018 and 2019 based on the selling price of newly issued shares of similar preferred stock to new investors using the common stock equivalent valuation method and adjusted for any applicable differences in conversion rights (in millions) : Three Months Ended June 30, Six Months Ended June 30, 2018 2019 2018 2019 Upward adjustments $ — $ 4 $ 1,984 $ 22 Downward adjustments (including impairment) — — — — Total unrealized gain for non-marketable equity securities $ — $ 4 $ 1,984 $ 22 The Company did not record any realized gains or losses for the Company’s non-marketable equity securities as of June 30, 2019 . The following table summarizes the total carrying value of the Company’s non-marketable equity securities held as of December 31, 2018 and June 30, 2019 including cumulative unrealized upward and downward adjustments made to the initial cost basis of the securities (in millions) : As of December 31, 2018 June 30, 2019 Initial cost basis $ 6,001 $ 6,041 Upward adjustments 1,984 2,006 Downward adjustments (including impairment) — — Total carrying value at the end of the period $ 7,985 $ 8,047

The Company concurrently issued approximately 2 million shares of Uber Technologies, Inc. Class A common stock, with a fair value of $52 million to MLU B.V.’s parent, Yandex. These shares are subject to a put/call feature resulting in Uber Technologies, Inc.’s contingent obligation to buy back these shares at $48 per share after twelve months from the closing date. Neither the put nor the call had been exercised as of June 30, 2019 . In exchange for consideration contributed, the Company received a seat on MLU B.V.’s board and a 38% equity ownership interest consisting of common stock in MLU B.V. Certain contingent equity issuances of MLU B.V. may dilute the Company’s equity ownership interest to approximately 35% . The investment was determined to be an equity method investment due to the Company’s ability to exercise significant influence over MLU B.V. The initial fair value of the Company’s equity method investment in MLU B.V. was estimated using discounted cash flows of MLU B.V. As a result of the loss of control over Uber Russia/CIS resulting from the transaction, the Company derecognized the assets/liabilities of Uber Russia/CIS and recorded a $954 million gain during the first quarter of 2018 recognized in other income (expense), net in the condensed consolidated statement of operations. Included in the initial carrying value of $1.4 billion , which represents the fair value on the transaction date, was a basis difference of $908 million related to the difference between the cost of the investment and the Company’s proportionate share of the net assets of MLU B.V. The carrying value of the equity method investments are primarily adjusted for the Company’s share in the losses of MLU B.V. and amortization of basis differences. The carrying value was also adjusted for currency translation adjustments representing fluctuations between the functional currency of the investee, the Ruble and the U.S. Dollar. As of June 30, 2019 , the basis differences between the carrying value of the Company’s investment and its share in the net assets of MLU B.V. amounted to $792 million , including the impact of foreign currency translation, and are comprised primarily of equity method goodwill. Equity method goodwill is not amortized. The Company amortizes the basis difference related to the intangible assets over the estimated useful lives of the assets that gave rise to the difference using the straight-line method. The weighted-average life of the intangible asset is approximately 5.3 years as of June 30, 2019 . The investment balance is reviewed for impairment whenever factors indicate that the carrying value of the equity method investment may not be recoverable.

These operating and finance leases will commence between fiscal year 2019 and fiscal year 2021 with lease terms of 1 year to 11 years . Failed Sale-Leaseback In 2015, the Company entered into a JV agreement with a real estate developer (“JV Partner”) to develop parcels of land (“the Land”) in San Francisco on which to construct the Company’s new headquarters buildings (the “Buildings”). The Buildings are to consist of two adjacent towers totaling approximately 423,000 rentable square feet. In connection with the JV arrangement, the Company had acquired a 49% interest in the JV, the principal asset of which was the Land on which the Buildings are to be constructed. In November 2016, the Company and the JV Partner agreed to dissolve the JV and terminate the Company’s commitment to the lease of the Buildings (together “the real estate transaction”). Under the terms of the real estate transaction, the Company obtained the rights and title to the partially constructed building, will complete the development of the two office buildings and retain a 100% ownership of the buildings. In connection with the real estate transaction, the Company also executed two 75 -year land lease agreements (“Land Leases”). As of June 30, 2019 , commitments under the Land Leases total $169 million until February 2032. After 2032, the annual rent amount will adjust annually based on the prevailing consumer price index. For accounting purposes, the real estate transaction is in substance the sale-leaseback of the Company’s 49% indirect interest in the land. Due to the Company’s continuing involvement through a purchase option on the Land, the Company failed to qualify for sale-leaseback accounting. A failed sale-leaseback transaction is accounted for as a financing transaction whereby the cash and deferred sales proceeds received in the real estate transaction are recorded as a financing obligation. Accordingly, the Company’s previous ownership in the JV, which represented its ownership interest in the Land of $65 million , is included in property and equipment, net, and a corresponding financing obligation of $79 million is included in other long-term liabilities as of June 30, 2019 . Future land lease payments of $1.8 billion will be allocated 49% to the financing obligation under the failed sale-leaseback arrangement and 51% to the operating lease of land.

The debt discount was amortized to interest expense at an effective interest rate of 13.7% . The Company was amortizing the discount over the period until the initial maturity date of the respective note.

During the first quarter of 2019, the warrant to purchase Series G redeemable convertible preferred stock was exercised in full and the fair value of the warrant was reclassified to redeemable convertible preferred stock. During the second quarter of 2019, the warrant to purchase Series E redeemable convertible preferred stock was exercised and automatically converted to shares of common stock as a result of the IPO. Upon closing of the IPO, all shares of the Company’s outstanding redeemable convertible preferred stock automatically converted into 905 million shares of common stock. The Company’s board of directors has the authority to issue up to 10 million shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. As of June 30, 2019 , there was no preferred stock issued and outstanding. PayPal, Inc. (“PayPal”) Private Placement On May 16, 2019, the Company closed a private placement by PayPal, Inc. in which it issued and sold 11 million shares of its common stock at a purchase price of $45.00 per share and received aggregate proceeds of $500 million . Additionally, PayPal and the Company agreed to extend their global partnership, including a commitment to jointly explore certain commercial collaborations. Restricted Common Stock The Company has granted restricted common stock to certain continuing employees, primarily in connection with acquisitions. Vesting of this stock may be dependent on a combination of service and performance conditions that become satisfied upon the occurrence of a qualifying event. The Company has the right to repurchase shares for which the vesting conditions are not satisfied. The following table summarizes the activity related to the Company’s restricted common stock for the six months ended June 30, 2019 (in thousands, except per share amounts): Number of Shares Weighted-average Grant-Date Fair Value per Share Unvested restricted common stock as of December 31, 2018 898 $ 30.33 Granted — $ — Vested (353 ) $ 34.82 Canceled (37 ) $ 34.86 Unvested restricted common stock as of June 30, 2019 508 $ 26.88 Equity Incentive Plans The Company maintains two equity incentive plans: the 2013 Equity Incentive Plan (“ 2013 Plan ”) and the 2010 Stock Plan (“ 2010 Plan ” and collectively, “ Plans ”). The 2013 Plan serves as the successor to the 2010 Plan and provides for the issuance of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), stock appreciation rights (“ SARs ”), restricted stock and RSUs to employees, consultants and advisors of the Company. In January 2019, the Company’s board of directors approved an amendment to the 2013 Plan to increase the number of shares of common stock reserved for issuance by 85 million shares, for a total of 293 million shares reserved. In March 2019, the Company’s board of directors adopted the 2019 Equity Incentive Plan (“2019 Plan”). The 2019 Plan was approved in April 2019 with 130 million shares of common stock reserved for future issuance. The 2019 Plan became effective on May 9, 2019 the date of the underwriting agreement between the Company and the underwriters for the IPO. The 2019 Plan is the successor to the 2013 Plan. The number of shares of the Company’s common stock available for issuance under the 2019 Plan automatically increases on January 1 of each year, for a period of not more than ten years , commencing on January 1, 2020 and ending on (and including) January 1, 2029 by the lesser of (a) 5% of the total number of the shares of common stock outstanding on December 31 of the immediately preceding calendar year, and (b) such number of shares determined by the Company’s board of directors. The Company’s 2019 Plan provides for the grant of ISOs, NSOs, SARs, restricted stock awards, RSUs, performance-based awards, and other awards (that are based in whole or in part by reference to the Company’s common stock) (collectively, “awards”). ISOs may be granted only to the Company’s employees, including the Company’s officers, and the employees of any parent or subsidiary. All other awards may be granted to the Company’s employees, including the Company’s officers, the Company’s non-employee directors and consultants, and the employees and consultants of the Company’s affiliates. Stock Option and SAR Activity A summary of stock option and SAR activity for the six months ended June 30, 2019 is as follows (in millions, except share amounts which are reflected in thousands, per share amounts, and years): SARs Outstanding Number of SARs Options Outstanding Number of Shares Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Life (in years) Aggregate Intrinsic Value As of December 31, 2018 758 42,936 $ 9.22 5.74 $ 1,456 Awards granted 73 250 $ 43.06 Awards exercised — (1,178 ) $ 2.39 Awards forfeited (11 ) (70 ) $ 32.71 As of June 30, 2019 820 41,938 $ 9.61 5.25 $ 1,572 Vested and expected to vest as of June 30, 2019 632 34,972 $ 4.34 4.87 $ 1,497 Exercisable as of June 30, 2019 632 34,972 $ 4.34 4.87 $ 1,497 RSU Activity The following table summarizes the activity related to the Company’s RSUs for the six months ended June 30, 2019 . For purposes of this table, vested RSUs represent the shares for which the service condition had been fulfilled during six months ended June 30, 2019 (in thousands, except per share amounts): Number of Shares Weighted-Average Unvested and outstanding as of December 31, 2018 75,835 $ 37.20 Granted 39,824 $ 44.32 Vested (17,655 ) $ 36.35 Canceled (5,420 ) $ 39.86 Unvested and outstanding as of June 30, 2019 92,584 $ 42.70 Stock-Based Compensation Expense Stock-based compensation expense is allocated based on the cost center to which the award holder belongs. The following table summarizes total stock-based compensation expense by function for the three and six months ended June 30, 2018 and 2019 (in millions) : Three Months Ended June 30, Six Months Ended June 30, 2018 2019 2018 2019 Operations and support $ 2 $ 404 $ 7 $ 405 Sales and marketing 1 212 4 213 Research and development 5 2,557 11 2,560 General and administrative 12 768 61 774 Total $ 20 $ 3,941 $ 83 $ 3,952 As of June 30, 2019 , there was $2.5 billion of unamortized compensation costs related to all unvested awards. The unamortized compensation costs are expected to be recognized over a weighted-average period of approximately 2.1 years . The Company has granted RSAs, RSUs, SARs, and stock options that vest only upon the satisfaction of both time-based service and performance-based conditions. Through May 9, 2019 , no stock-based compensation expense had been recognized for such awards with a performance condition based on the occurrence of a qualifying event (such as an IPO), as such qualifying event was not probable. Upon the Company’s IPO, the Company recognized $3.6 billion of stock-based compensation expense related to such awards. To meet the related tax withholding requirements, the Company withheld 29 million of the 76 million shares of common stock issued. The 29 million shares of common stock withheld for taxes were returned to the shares reserved for future issuance under the Company’s 2019 Plan. Based on the IPO public offering price of $45.00 per share, the tax withholding obligation was $1.3 billion . For additional information related to the Company’s IPO, refer to Note 1 - Basis of Presentation and Summary of Significant Accounting Policies . The tax benefits recognized in income for stock-based compensation arrangements were not material during the three and six months ended June 30, 2018 and 2019 , respectively. 2019 Employee Stock Purchase Plan In March 2019, the Company’s board of directors adopted the Company’s Employee Stock Purchase Plan (“ESPP”), and in April 2019, the Company’s stockholders approved its ESPP. The ESPP became effective on May 9, 2019, the date of the underwriting agreement between the Company and the underwriters for the IPO. There are 25 million shares of common stock reserved for issuance under the ESPP. The number of shares of the Company’s common stock available for issuance under the ESPP automatically increases on January 1 of each year, beginning in 2020 and continuing through 2029, by the lesser of (a) 1.0% of the total number of shares of common stock outstanding on December 31 of the immediately preceding calendar year, and (b) 25,000,000 shares. However, the Company’s board of directors or compensation committee may reduce the amount of the increase in any particular year. The stock-based compensation expense recognized for the ESPP was not material during the three months ended June 30, 2019 .

Income Tax Disclosure [Abstract]
Income TaxesNote 11 - Income Taxes The Company computes its quarterly income tax expense/(benefit) by using a forecasted annual effective tax rate and adjusts for any discrete items arising during the quarter. The Company recorded an income tax expense of $28 million and $604 million for the three and six months ended June 30, 2018 , respectively, and an income tax benefit of $2 million and an income expense of $17 million for the three and six months ended June 30, 2019 , respectively. During the three months ended June 30, 2018 , income tax expense was primarily driven by current tax on foreign earnings partially offset by the benefit of U.S. losses. During the six months ended June 30, 2018 , income tax expense was primarily driven by deferred U.S. tax expense related to the Company’s investment in Didi and Grab, deferred China tax related to the Company’s investment in Didi, and to a lesser extent, the benefit of U.S. losses and current tax on foreign earnings. During the three and six months ended June 30, 2019 , income tax expense was primarily driven by current tax on foreign earnings offset by a partial benefit from U.S. losses. The primary differences between the effective tax rate and the federal statutory tax rate are due to the valuation allowance on the Company’s U.S. and Netherlands’ deferred tax assets and foreign tax rate differences. In March 2019, the Company initiated a series of transactions resulting in changes to its international legal structure, including a redomiciliation of a subsidiary to the Netherlands and a transfer of certain intellectual property rights among wholly owned subsidiaries, primarily to align its structure to its evolving operations. The redomiciliation resulted in a step-up in the tax basis of intellectual property rights and a correlated increase in foreign deferred tax assets in an amount of $6.1 billion , net of a reserve for uncertain tax positions of $1.3 billion . Based on available objective evidence, management believes it is not more-likely-than-not that these additional foreign deferred tax assets will be realizable as of June 30, 2019 and, therefore, are offset by a full valuation allowance to the extent not offset by reserves from uncertain tax positions. During the six months ended June 30, 2019 , the amount of gross unrecognized tax benefits increased by $1.2 billion , of which substantially all, if recognized, would not affect the annual effective tax rate as these unrecognized tax benefits would increase deferred tax assets that would be subject to a full valuation allowance. In the second quarter of 2019, the Company settled the IRS audit for the tax years 2013 and 2014. The settlement resulted in a reduction of unrecognized tax benefits of $141 million , which did not affect the annual effective tax rate, as these unrecognized tax benefits decreased deferred tax assets that were subject to a full valuation allowance. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The Company is also under routine examination by various state and foreign tax authorities. The Company believes that adequate amounts have been reserved in these jurisdictions. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by federal, state or foreign tax authorities to the extent utilized in a future period. For the Company’s major tax jurisdictions, the tax years 2010 through 2019 remain open; the major tax jurisdictions are the U.S., Brazil, Netherlands, Mexico, United Kingdom, Australia, Singapore, and India. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, the Company is unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. In the event the Company experiences an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), the Company’s ability to utilize net operating losses, tax credits and other tax attributes may be limited. The most recent analysis of the Company’s historical ownership changes was completed through June 30, 2019. Based on the analysis, the Company does not anticipate a current limitation on the tax attributes.

Segment Reporting [Abstract]
Segment Information and Geographic InformationNote 13 - Segment Information and Geographic Information The Company operates its business as two operating and reportable segments: Core Platform and Other Bets. The Company determined its operating segments based on how the chief operating decision maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. The Company’s operating performance measure is contribution profit (loss). The CODM does not evaluate operating segments using asset information. Contribution profit (loss) is defined as revenue less the following expenses: cost of revenue, operations and support, sales and marketing, and general and administrative and research and development expenses associated with the Core Platform and Other Bets segments. Contribution profit (loss) also excludes any non-cash items or items that management does not believe are reflective of the Company’s ongoing core operations (as shown in the table below). Included in the reconciliation below are expenses associated with research and development activities that are not directly attributable to the Core Platform and Other Bets segments: ATG and Other Technology Programs. ATG includes research and development expenses associated with developing autonomous vehicle technology. Other Technology Programs includes research and development expenses associated with developing all other next-generation technologies. In June 2019, the Company announced a number of leadership and organizational changes. These organizational changes will be effective in the third quarter of 2019. The Company is currently evaluating the impact to its operating and reportable segments based on how the businesses will be managed subsequent to the changes. During the three and six months ended June 30, 2019, the Company’s CODM continued to manage the business, allocate resources, make operating decisions, and evaluate operating performance under the existing operating and reportable segments: Core Platform and Other Bets. The following table provides information about the Company’s segments and a reconciliation of the total segment contribution profit (loss) to loss from operations (in millions): Three Months Ended June 30, Six Months Ended June 30, 2018 2019 2018 2019 Contribution profit (loss): Core Platform $ 369 $ 220 $ 796 $ 103 Other Bets (28 ) (122 ) (48 ) (193 ) Total segment contribution profit (loss) 341 98 748 (90 ) Reconciling items: Research and development expenses related to ATG and Other Technology Programs (1) (129 ) (105 ) (246 ) (202 ) Unallocated research and development and general and administrative expenses (1), (2) (488 ) (649 ) (956 ) (1,233 ) Depreciation and amortization (98 ) (123 ) (186 ) (269 ) Stock-based compensation expense (20 ) (3,941 ) (83 ) (3,952 ) Legal, tax, and regulatory reserves and settlements (252 ) (380 ) (252 ) (380 ) Driver appreciation award — (299 ) — (299 ) Payroll tax on IPO stock-based compensation — (86 ) — (86 ) Asset impairment/loss on sale of assets (81 ) — (113 ) (8 ) Acquisition and financing related expenses — — (15 ) — Gain on restructuring of lease arrangement 4 — 4 — Impact of 2018 Divested Operations (1), (3) (16 ) — (118 ) — Loss from operations $ (739 ) $ (5,485 ) $ (1,217 ) $ (6,519 ) (1) Excluding stock-based compensation expense.

Commitments and Contingencies Disclosure [Abstract]
Commitments and ContingenciesNote 14 - Commitments and Contingencies Purchase Commitments The Company has commitments for network and cloud services, background checks, and other items in the ordinary course of business with varying expiration terms through 2022 . These amounts are determined based on the non-cancelable quantities or termination amounts to which the Company is contractually obligated. As of June 30, 2019 , there were no material changes to the Company’s purchase commitments disclosed in the financial statements included in the Prospectus . Contingencies From time to time, the Company may be a party to various claims, non-income tax audits and litigation in the normal course of business. As of December 31, 2018 and June 30, 2019 , the Company had recorded aggregate liabilities of $1.1 billion and $1.6 billion , respectively, in accrued and other current liabilities on the condensed consolidated balance sheets for all of its legal, regulatory and non-income tax matters that were probable and reasonably estimable. The Company is currently party to various legal and regulatory matters that have arisen in the normal course of business and include, among others, alleged independent contractor misclassification claims, Fair Credit Reporting Act (“FCRA”) claims, background check violations, consumer and driver class actions relating to pricing and advertising, unfair competition matters, intellectual property disputes, employment discrimination and other employment-related claims, Telephone Consumer Protection Act (“TCPA”) cases, Americans with Disabilities Act (“ADA”) cases, data and privacy matters, and other matters. With respect to the Company’s outstanding legal and regulatory matters, based on its current knowledge, the Company believes that the amount or range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows. However, the outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. O’Connor, et al., v. Uber Technologies, Inc. and Yucesoy v. Uber Technologies, Inc., et al. O’Connor and Yucesoy are two putative class actions that assert various independent contractor misclassification claims brought on behalf of certain Driver Partners in California and Massachusetts, respectively. The two cases were consolidated and both are pending in the United States District Court for the Northern District of California. Filed on August 16, 2013 in the United States District Court for the Northern District of California, the O’Connor action is a class action against the Company on behalf of all Driver Partners who contracted with the Company in California between 2009 and February 28, 2019 and seeks damages for tips and business expense reimbursement based on alleged independent contractor misclassification and unfair competition. The O’Connor action was stayed in the trial court pending the outcome of appeals before the Ninth Circuit Court of Appeals regarding the trial court’s orders denying the Company’s motions to compel arbitration, order certifying the class action, and order enjoining the Company’s enforcement of its arbitration agreement. The Ninth Circuit issued its rulings on those appeals on September 25, 2018, finding that the Company’s arbitration agreements were enforceable and accordingly, decertified the O’Connor class and remanded the case to the district court for further proceedings. Filed on June 2, 2014 in the Massachusetts Suffolk County Superior Court, the Yucesoy action is a class action against the Company on behalf of all Driver Partners in Massachusetts and seeks damages based on independent contractor misclassification, tips law violations and tortious interference with contractual and/or advantageous relations. Plaintiffs filed an amended complaint in the Yucesoy action on March 30, 2018 adding new class representatives, to which the Company filed a motion to compel arbitration and/or dismiss the action on April 26, 2018. On March 11, 2019, the parties entered into a Settlement Agreement which provides that the Company will pay $20 million to settle the O’Connor and Yucesoy actions. The proposed settlement does not require the Company to start classifying Driver Partners as employees in California or Massachusetts and does not include those Driver Partners who are subject to arbitration. Plaintiffs filed a motion with the United States District Court for the Northern District of California seeking court approval of the settlement agreement. The motion for preliminary approval of the parties’ settlement agreement was heard on March 21, 2019, and preliminary approval was granted subject to certain conditions. The final approval hearing is set for August 29, 2019. In May 2019, the Company reached agreements to resolve independent contractor misclassification claims of Driver Partners in California and Massachusetts that have filed (or expressed an intention to file) arbitration demands. Under the agreements, certain Driver Partners are eligible for settlement payments, subject to a threshold number of the covered Driver Partners entering into individual settlement agreements. The Company anticipates the aggregate amount of payments to Driver Partners under these individual settlement agreements, together with attorneys’ fees, will fall within an approximate range of $146 million to $170 million . State Unemployment Taxes In December 2016, following an audit opened in 2014 investigating whether Driver Partners were independent contractors or employees, the Company received a Notification of Assessment from the Employment Development Department, State of California, for payroll tax liabilities. The notice retroactively imposed various payroll tax liabilities on the Company, including unemployment insurance, employment training tax, state disability insurance, and personal income tax. The Company has filed a petition with an administrative law judge of the California Unemployment Insurance Appeals Board appealing the assessment. Google v. Levandowski & Ron; Google v. Levandowski On October 28, 2016, Google filed arbitration demands against each of Anthony Levandowski and Lior Ron, former employees of Google, alleging breach of their respective employment agreements with Google, fraud and other state law violations (due to soliciting Google employees and starting a new venture to compete with Google’s business in contravention of their respective employment agreements). Google seeks damages, injunctive relief, and restitution. The arbitration hearing was held from April 30 to May 11, 2018. On March 26, 2019, the arbitration panel issued an interim award, finding against each of Google’s former employees and awarding $127 million against Anthony Levandowski and $1 million for which both Anthony Levandowski and Lior Ron are jointly and severally liable. In July 2019, Google submitted briefing on its request for interest, attorneys fees, and costs related to these claims. Pursuant to a contractual obligation, Uber is indemnifying both employees with respect to certain claims. Whether Uber is ultimately responsible for such indemnification, however, depends on the exceptions and conditions set forth in the indemnification agreement. The ultimate resolution of the matter could result in a possible loss of up to $62 million or more (depending on the date of the final award) in excess of the amount accrued. Uber is not a party to either of these arbitrations. Taiwan Regulatory Fines Prior to the Company adjusting and re-launching its operating model in April 2017 to a model where government-approved rental companies provide transport services to Riders, Driver Partners in Taiwan and Uber Taiwan have been fined by Taiwan’s Ministry of Transportation and Communications in significant numbers across Taiwan. On January 6, 2017, a new Highways Act came into effect in Taiwan which increased maximum fines from New Taiwan Dollar (“NTD”) 150,000 to NTD 25 million per offense. The Company suspended its service in Taiwan from February 10, 2017 to April 12, 2017, but a number of these fines were issued to Uber Taiwan in connection with rides that took place in January and February 2017 prior to the suspension. These fines have remained outstanding while Uber appeals the tickets through the courts. Beginning in July 2018, the Taiwan Supreme Court issued a number of positive rulings in which it rejected the government’s approach of issuing one ticket per ride. The Taiwan government continues to appeal these rulings to the Supreme Court. Copenhagen Criminal Prosecution In May 2017, the Danish police announced that they would use tax data about Driver Partners obtained from the Dutch tax authorities to prosecute Driver Partners for unlicensed taxi traffic. The tax data covers calendar years 2015 and prior. The prosecutor indicted four Driver Partners as test cases which have been heard by the Copenhagen City Court, the Appeal Court and finally the Supreme Court. In addition, on October 6, 2017, the Company has been preliminary charged with aiding and abetting illegal taxi traffic in 2015. In September 2018, the Danish Supreme Court ruled on these test cases that the Driver Partners were carrying out illegal taxi operations and fined them in the total amount of their earnings from performing ridesharing services. The Court also confirmed that the use of the relevant tax data obtained from the Dutch tax authorities was validly used as evidence in the prosecutions and was used to assess the fines payable. In January 2018, the Company received another request from the Danish tax authorities through the Dutch tax authorities to disclose tax data about Driver Partners for years 2016 and 2017. Such tax data for years 2016 to 2017 has subsequently been provided by the Company to the Danish tax authorities. On May 29, 2018, the Company received another set of indictment papers from the Danish prosecutor. On February 19, 2019, the Company was informed by the Danish prosecutor that it has issued a request for legal aid to the Danish prosecutor to serve additional indictment papers, relating to the Company’s activity in Denmark in 2016 and 2017. On May 13, 2019, the Company was notified by the Dutch tax authorities that data related to the Company’s activity in Denmark in 2016 and 2017 could not be used by Danish authorities for the purpose of attempting to establish fraud in connection with taxi licenses. The Company has not operated these services in Denmark since 2017 and currently does not have operations in Denmark. Malden Transportation v. Uber Technologies, Inc. Seven consolidated actions were filed in the United District Court for the District of Massachusetts by taxi medallion owners Malden Transportation, Inc., Anoush Cab, Inc., Dot Ave Cab, Inc., Gill & Gill, Inc., Max Luc Taxi, Inc., Sycoone Taxi, Inc., Taxi Maintenance, Inc. in late 2016 and early 2017 against the Company alleging unfair competition violations (on the grounds that the Company failed to comply with local taxi laws), as well as state and federal antitrust violations (on the grounds that the Company prices trips below cost in order to achieve a monopoly). Antitrust claims were dismissed, but the unfair competition claims remain. On May 15, 2019, Uber reached a tentative settlement with the plaintiffs in six of the seven actions, subject to negotiation of specific terms and execution of a settlement agreement. A bench trial of the seventh action (Anoush Cab, Inc.), began on July 18, 2019 and concluded on August 2, 2019. The parties submitted their proposed findings of fact and conclusions of law to the court on August 6, 2019. Swiss Social Security Reclassification Several Swiss government bodies currently classify Driver Partners as employees of Uber Switzerland for social security purposes. A number of such decisions have been made by these governmental bodies. The Company is challenging each of them. The Cantonal Court of Zurich issued a ruling with regard to certain test cases on July 20, 2018. The court canceled the decisions on the grounds that certain decisions were made against the Company’s Swiss local entity without proof that there is a contractual relationship between the Company’s Swiss local entity and the Driver Partners (who actually contract with Uber B.V.). This ruling was not appealed and the Swiss governmental bodies continue to investigate the identity of the employer. On July 5, 2019, the Swiss governmental bodies issued four decisions by which they reclassified four drivers as Uber B.V. and Rasier B.V. employees and consider that Uber Switzerland should pay social security contributions. The Company plans to appeal those decisions. The Company’s chances of success on the merits are still uncertain and any possible loss or range of loss cannot be estimated. Non-Income Tax Matters The Company recorded an estimated liability for contingencies related to non-income tax matters and is under audit by various domestic and foreign tax authorities with regard to such matters. The subject matter of these contingent liabilities and non-income tax audits primarily arises from the Company’s transactions with its Driver Partners, as well as the tax treatment of certain employee benefits and related employment taxes. In jurisdictions with disputes connected to transactions with Driver Partners, disputes involve the applicability of transactional taxes (such as sales, value added and similar taxes) to services provided, as well as the applicability of withholding tax on payments made to such Driver Partners. For example, the Company is involved in a proceeding in the UK involving HMRC, the tax regulator in the UK, which is seeking to classify the Company as a transportation provider. Being classified as a transportation provider would result in a VAT ( 20% ) on Gross Bookings or on the service fee that the Company charges Drivers, both retroactively and prospectively. HMRC could also determine that the Company is an employer for tax purposes, resulting in up to 14% national insurance contributions being payable by the Company on driver income. Further, if Drivers are determined to be workers, they may be entitled to additional benefits and payments, and the Company may be subject to penalties, back taxes, and fines. The Company believes that the position of HMRC and the regulators in similar disputes and audits is without merit and is defending itself vigorously. The Company’s estimated liability is inherently subjective due to the complexity and uncertainty of these matters and the judicial processes in certain jurisdictions, therefore, the final outcome could be different from the estimated liability recorded. Other Legal and Regulatory Matters The Company has been subject to various government inquiries and investigations surrounding the legality of certain of the Company’s business practices, compliance with global regulatory requirements, such as antitrust and Foreign Corrupt Practices Act requirements, data protection and privacy laws, and the infringement of certain intellectual property rights. The Company has investigated many of these matters and is implementing a number of recommendations to its managerial, operational and compliance practices, as well as seeking to strengthen its overall governance structure. In many cases, the Company is unable to predict the outcomes and implications of these inquiries and investigations on the Company’s business which could be time consuming, costly to investigate and require significant management attention. Furthermore, the outcome of these inquiries and investigations could negatively impact the Company’s business, reputation, financial condition and operating results, including possible fines and penalties and requiring changes to operational activities and procedures. Indemnifications In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with third parties. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its activities or non-compliance with certain representations and warranties made by the Company. In addition, the Company has entered into indemnification agreements with its officers, directors, and certain current and former employees, and its certificate of incorporation and bylaws contain certain indemnification obligations. It is not possible to determine the maximum potential loss under these indemnification provisions / obligations because of the unique facts and circumstances involved in each particular situation.

Variable Interest Entity [Abstract]
Variable Interest Entities (VIEs)Note 15 - Variable Interest Entities ("VIEs") Consolidated VIE As of December 31, 2017, the Company consolidated a VIE entity as it had an option to acquire all the outstanding membership interests in the entity and had the obligation to fully fund the entity’s operations. In 2018, the Company exercised its option. Under an amended agreement, and upon satisfaction of certain closing conditions associated with exercising its option, the Company created a new majority-owned subsidiary, Uber Freight. Refer to Note 16 - Non-Controlling Interest for further information. Total assets included on the condensed consolidated balance sheets for this VIE as of December 31, 2018 and June 30, 2019 were $115 million and $132 million , respectively. Total liabilities included on the condensed consolidated balance sheets for this VIE as of December 31, 2018 and June 30, 2019 were not material . Unconsolidated VIE Mission Bay 3 & 4 The Mission Bay 3 & 4 joint venture (“JV”) refers to Event Center Office Partners, LLC (“ECOP”), a joint venture entity established in March 2018, by Uber and two companies (“LLC Partners”) to manage the operation of two office buildings owned by two ECOP wholly-owned subsidiaries. The Company contributed $136 million cash in exchange for a 45% interest in ECOP. Each of the two LLC Partners owns 45% and 10% , respectively. The amount of contributed cash was recorded as an investment for $136 million as of June 30, 2019 . The remaining construction costs will be funded through a construction loan obtained by ECOP where the Company together with the two LLC Partners guarantee payments and performance of the loan when it becomes due and any payment of costs incurred by the lender under limited situations. The maximum collective guarantee liability is up to $50 million . The Company evaluated the nature of its investment in ECOP and determined that ECOP is a VIE during the construction period; however, the Company is not the primary beneficiary as decisions are made jointly between parties and therefore does not have the power to direct activities that most significantly impact the VIE. The Company will reevaluate if ECOP meets the definition of a VIE upon specific reconsideration events, including completion of construction. The maximum exposure to loss represents the potential loss recognized by the Company relating to these unconsolidated entities. The Company believes that its maximum exposure to loss is limited because it is a member of the limited liability company. The Company’s maximum exposure to loss differs from the carrying value of the variable interests. The maximum exposure to loss is dependent on the nature of the variable interests in the VIE and is limited to the investment balances and notional amounts of guarantees. As of December 31, 2018 and June 30, 2019 , the carrying amount of assets and liabilities recognized on the condensed consolidated balance sheets related to the Company’s interests in unconsolidated VIEs and the Company’s maximum exposure to loss relating to unconsolidated VIEs was as follows (in millions) : As of December 31, 2018 June 30, 2019 Investment $ 78 $ 136 Additional cash contribution 58 — Limited guarantee 50 50 Maximum exposure to loss $ 186 $ 186 Uber has significant influence over ECOP and accounts for its investment in ECOP under the equity method. No equity earnings have been recognized as of June 30, 2019 , since the sole activity of the ECOP consists of construction of the assets and costs incurred are capitalized. Once construction is complete, at each reporting period, the Company will adjust the carrying value of its investment to reflect its proportionate share of ECOP’s income or loss, and any impairments, with a corresponding credit or debit, respectively, to loss from equity method investment, net of tax in the condensed consolidated statements of operations . As of June 30, 2019 , the Company determined that no impairment of its equity method investments existed.

Noncontrolling Interest [Abstract]
Non-Controlling InterestNote 16 - Non-Controlling Interest Non-controlling interest is classified in mezzanine equity as it is redeemable on an event that is not solely in the control of the Company. The non-controlling interest is redeemable at fair value beginning at future dates at the holders’ option and prior to the occurrence of certain events. The non-controlling interest is not remeasured to fair value because it is currently not probable that the non-controlling interest will become redeemable because of the likelihood of occurrence of certain events that would prevent it from becoming redeemable. If the non-controlling interest becomes probable of being redeemable, the Company will remeasure the non-controlling interest with changes in the carrying value recognized in additional paid-in capital. As of December 31, 2018, the Company owned 100% of the issued and outstanding capital stock of its subsidiary that operates its JUMP e-bike and e-scooter products, or 81% on a fully-diluted basis if all shares reserved for issuance under its JUMP employee incentive plan were issued and outstanding. In April 2019, the JUMP employee incentive plan was terminated and the JUMP subsidiary became a wholly-owned subsidiary of the Company. All unvested and unexercised equity awards under the terminated JUMP employee incentive plan were canceled. Certain JUMP employees who held such unvested and unexercised equity awards under the terminated JUMP employee incentive plan received grants of the Company’s RSUs pursuant to the 2013 Plan. The fair value of the RSU grants and the impact on the Company’s financial statements were not material. As of December 31, 2018 and June 30, 2019, the Company owned 89% of the issued and outstanding capital stock of its subsidiary that operates its Uber Freight offering, or 80% on a fully-diluted basis if all shares reserved for issuance under the Company’s Uber Freight employee incentive plan were issued and outstanding. As of June 30, 2019 , no equity awards under the Uber Freight employee incentive plan had been granted. The minority stockholders of the Company’s subsidiary that operate its Uber Freight offering, including any holders of equity awards issued under the employee equity incentive plans and employees who hold fully vested shares, have put rights to sell certain of their equity interests at fair market value at specified periods of time that terminates upon the earliest of the closing of a liquidation transaction or an IPO of the subsidiary. Should the put rights be exercised, they can be satisfied in either cash, Uber stock, or a combination of cash and Uber stock based upon the Company’s election. The Company attributes the pro rata share of the Uber Freight’s net income or loss to the redeemable non-controlling interests based on the outstanding ownership of the minority shareholders during the period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of PresentationBasis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2018 , included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (“the Securities Act”), on May 13, 2019 (“the Prospectus”). In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. There have been no changes to the Company’s significant accounting policies described in the Prospectus that have had a material impact on the Company’s condensed consolidated financial statements and related notes, except for the adoption of the new accounting standard related to lease accounting.
Basis of ConsolidationBasis of Consolidation The condensed consolidated financial statements of the Company include the accounts of the Company and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 15 - Variable Interest Entities ("VIEs") for further information.
Use of EstimatesUse of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, the Company evaluates its estimates, including those related to the incremental borrowing rate (“IBR”) applied in lease accounting, accounts receivable allowances, fair values of investments and other financial instruments, useful lives of amortizable long-lived assets and intangible assets, stock-based compensation, income and non-income taxes, insurance reserves, and contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates.
LeasesLeases The Company accounts for leases in accordance with ASC 842, Leases (“ASC 842”), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The Company adopted ASC 842 along with all subsequent ASU clarifications and improvements that are applicable to the Company, on January 1, 2019, using the modified retrospective transition method and used the effective date as the date of initial application. Consequently, financial information is not updated and the disclosures required under ASC 842 are not provided for dates and periods before January 1, 2019. ASC 842 provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permits the Company not to reassess under ASC 842 its prior conclusions about lease identification, lease classification and initial direct costs. The Company also made a policy election not to separate non-lease components from lease components, therefore, it will account for lease component and the non-lease components as a single lease component. The Company determines if a contract contains a lease based on whether it has the right to obtain substantially all of the economic benefits from the use of an identified asset and whether it has the right to direct the use of an identified asset in exchange for consideration, which relates to an asset which the Company does not own. Right of use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are recognized as the lease liability, adjusted for lease incentives received. Lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s IBR, because the interest rate implicit in most of the Company’s leases is not readily determinable. The IBR is a hypothetical rate based on the Company’s understanding of what its credit rating would be to borrow and resulting interest the Company would pay to borrow an amount equal to the lease payments in a similar economic environment over the lease term on a collateralized basis. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in the Company’s lease liability calculation. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The lease term of operating and finance leases vary from less than a year to 76 years . The Company has leases that include one or more options to extend the lease term for up to 14 years as well as options to terminate the lease within one year. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating leases are included in operating lease right to use assets, operating lease liabilities, current and operating lease liabilities, non-current on the Company’s condensed consolidated balance sheets . Finance leases are included in property and equipment, net, accrued and other current liabilities, and other long-term liabilities on the Company’s condensed consolidated balance sheets
Cash and Cash EquivalentsCash and Cash Equivalents Cash and cash equivalents as of June 30, 2019 consisted of cash held in checking and savings accounts as well as investments in money market funds and U.S. government securities. The Company considers all highly-liquid investments purchased with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash includes amounts collected on behalf of, but not yet remitted to Partners, which are included in accrued and other current liabilities on the consolidated balance sheets.
Recent Accounting PronouncementsRecently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Upon adoption of the new leasing standard on January 1, 2019, the Company recognized ROU assets of $888 million and lease liabilities of $963 million . The Company reassessed the build-to-suit leases that no longer meet the control-based build-to-suit model and derecognized $392 million in build-to-suit assets, $350 million corresponding financing obligation, and recorded $9 million of deferred tax liability. The initial cash contribution to the Mission Bay 3 & 4 joint venture that was previously reported as a defeasance of a build-to-suit financing obligation of $60 million was derecognized by reclassifying it as an increase to the Mission Bay 3 & 4 equity method investment. The $9 million difference between the total derecognized assets and total derecognized liabilities was recorded in the opening balance of accumulated deficit, net of tax, as of January 1, 2019. In July 2017, the FASB issued ASU 2017-11, “Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception” to simplify the accounting for certain instruments with down round features. The amendments require companies to disregard the down round feature when assessing whether the instrument is indexed to its own stock, for purposes of determining liability or equity classification. Further, companies that provide earnings per share (“EPS”) data will adjust the basic EPS calculation for the effect of the feature when triggered and will also recognize the effect of the trigger within equity. The Company adopted this new standard as of January 1, 2019 and applied the changes retrospectively. The adoption of the new standard did not have a material impact on the Company’s condensed consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, “Improvements to Non-Employee Share-Based Payment Accounting,” which expands the scope of Topic 718, to include share-based payments issued to non-employees for goods or services. The new standard supersedes Subtopic 505-50. The Company adopted the new standard effective January 1, 2019 on a modified retrospective basis. The new standard did not have a material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” to require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The standard also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements in ASC 820, “Fair Value Measurement” (“ASC 820”). The new standard is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements. In October 2018, the FASB issued ASU 2018-17, “Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest and requires organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
Non-Controlling InterestNon-controlling interest is classified in mezzanine equity as it is redeemable on an event that is not solely in the control of the Company. The non-controlling interest is redeemable at fair value beginning at future dates at the holders’ option and prior to the occurrence of certain events. The non-controlling interest is not remeasured to fair value because it is currently not probable that the non-controlling interest will become redeemable because of the likelihood of occurrence of certain events that would prevent it from becoming redeemable. If the non-controlling interest becomes probable of being redeemable, the Company will remeasure the non-controlling interest with changes in the carrying value recognized in additional paid-in capital.
