Noncontrolling Interest [Abstract]
Non-Controlling Interests	Note 17 – Non-Controlling Interests We have several consolidated subsidiaries that have issued common stock and preferred stock or preferred units to third party investors, representing non-controlling interests. As of December 31, 2020 and 2021, the amounts of non-controlling interests represented by subsidiaries’ preferred units and preferred stock were $1.3 billion and $1.0 billion, respectively. ATG Investment: Preferred Unit Purchase Agreement In July 2019, we closed a Preferred Unit Purchase Agreement with SoftBank, Toyota, and DENSO (collectively “the Investors”) for purchase by the Investors of Class A Preferred Units (“Preferred Units”) in Apparate. Apparate, a subsidiary of ours, issued 1.0 million Preferred Units at $1,000 per unit to the Investors for an aggregate consideration of $1.0 billion ($400 million from Toyota, $333 million from SoftBank, and $267 million from DENSO). As of December 31, 2020, the Preferred Units represented an aggregate 14.2% ownership interest in Apparate on an as-converted basis. As of December 31, 2020, we retained the remaining 85.8% ownership interest. SoftBank and Toyota are our existing investors. At the option of the Investors, the Preferred Units are convertible into common units of Apparate, initially on a one-for-one basis but subject to potential adjustment, as defined by the Preferred Unit Purchase Agreement at any time. The Preferred Units are entitled to certain distributions, including primarily dividends which are payable in cash or in-kind (at Apparate's discretion), and accrue quarterly, compounded on the last day of each quarter at a 4.5% annual rate. The Preferred Units are entitled to distributions upon the occurrence of a sale or liquidation of Apparate representing an amount that is equal to the greater of (i) the original investment plus any accrued but unpaid amounts, and (ii) their share of distributions assuming conversion to common units of Apparate immediately prior to the sale or liquidation event. The quarterly dividend, along with any attributed prorated share of Apparate’s net income (if applicable), are included in net income (loss) attributable to non-controlling interests, net of tax in our consolidated statements of operations. The Preferred Units do not participate in net losses due to a liquidation preference. SoftBank’s Preferred Units Beginning on July 2, 2026, SoftBank has the option to put to us all, but not less than all, of its initial investment in Preferred Units at a price equal to the number of SoftBank’s Preferred Units multiplied by the greater of (i) the original investment plus any accrued but unpaid amounts per unit and (ii) the fair value of the Preferred Units at the time of conversion (the “Put/Call Price”). Beginning on July 2, 2026, we can call all, but not less than all, of the Preferred Units held by SoftBank at the Put/Call Price. We have the option to settle all, or a portion of, the Put/Call Price with its common stock and any remainder will be satisfied in cash. The put and call were determined to be embedded features within the SoftBank Preferred Units since they are not separately exercisable or legally detached from the SoftBank Preferred Units. As of December 31, 2020, the SoftBank Preferred Units were classified as redeemable non-controlling interests in our consolidated financial statements and reported at the Put/Call Price which was determined as of the balance sheet date. The initial fair value of SoftBank’s Preferred Units was determined based on a hybrid method with the option pricing model as the primary methodology. This method used Level 3 fair value measurement inputs as well as an assumed equal probability of the occurrence of a liquidation or exit event. The significant unobservable inputs used in the initial fair value measurement include: volatility of 42%, time to liquidity of 5 years, and a discount for lack of marketability of 17%. A market approach was also used to corroborate the valuation derived from the hybrid method at issuance to evidence that the issuance price of the Preferred Units approximated their fair value. There was no fair value adjustment to SoftBank’s redeemable non-controlling interests during the year ended December 31, 2020. Toyota and DENSO’s Preferred Units As of December 31, 2020, the Toyota and DENSO Preferred Units were classified as non-redeemable non-controlling interests as these units were not subject to any mandatory redemption rights or redemption rights that are outside our control. ATG Collaboration Agreement with Apparate, Toyota and DENSO In conjunction with the Preferred Unit Purchase Agreement discussed above, we entered into a three-year joint collaboration agreement among Toyota, DENSO, and Apparate to develop next-generation self-driving technology (the “ATG Collaboration Agreement”), which became effective as of the closing of the Preferred Unit Purchase Agreement in July 2019. Pursuant to the ATG Collaboration Agreement, Toyota would make cash payments to Apparate up to an aggregate of $300 million, payable in six semi-annual installments during the three-year term of the ATG Collaboration Agreement. The cash payments for each six-month period were contingent upon the mutual agreement between the parties on the development activities and milestones to be achieved in the next six months and the continuation of the ATG Collaboration Agreement. The ATG Collaboration Agreement was within the scope of ASC 808, Collaborative Arrangements. The development activities were considered ongoing and central to the activities of ATG. As a result, the amounts received from Toyota were recognized as collaboration revenue in the All other segment (formerly ATG and Other Technology Programs) ratably over the respective six-month service period to which each payment relates, as the related development activities are performed. During the years ended December 31, 2019 and 2020, we recognized $42 million and $100 million, respectively, as revenue under the ATG Collaboration Agreement. Divestiture of ATG Business to Aurora On January 19, 2021, we completed the previously announced sale of our ATG Business to Aurora. As a result, our controlling interest and the non-controlling interests in the ATG Business were settled and ownership of the ATG Business transferred to Aurora. We derecognized the carrying value of non-controlling interests in the ATG Business of $1.1 billion, which included Toyota and DENSO non-redeemable non-controlling interests of $701 million and Softbank’s redeemable non-controlling interests of $356 million. Refer to Note 19 – Divestitures for further information. Freight Holding As of December 31, 2020 and 2021, we owned 85% and 78%, respectively, of the issued and outstanding capital stock of our subsidiary Freight Holding, or 79% and 75%, respectively, on a fully-diluted basis if all common shares reserved for issuance under our Freight Holding employee incentive plan were issued and outstanding. As of December 31, 2020 and 2021, under the Freight Holding incentive plan, a total number of 99.8 million shares of Freight Holding are reserved. As of December 31, 2020 and 2021, 83.8 million and 85.0 million shares, respectively, were available for grant and issuance. The redeemable non-controlling interest of Freight Holding is not accreted to redemption value because it is currently not probable that the non-controlling interest will become redeemable. Holders of Common Stock of Freight Holding The minority common stockholders of our subsidiary Freight Holding, including any holders of common 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 value to us 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 our election. As of December 31, 2020 and 2021, the minority common stockholders ownership in Freight Holding is classified as a redeemable non-controlling interest, because it is redeemable on an event that is not solely in our control. We attribute the pro rata share of the Freight Holding’s net income or loss available to holders of common stock to the redeemable non-controlling interests generated from common shares of Freight Holding based on the outstanding ownership of the minority shareholders of common shares during the period. Freight Series A Preferred Stock In October 2020, Freight Holding entered into a 2020 Freight Series A Preferred Stock Purchase Agreement with a 2020 Freight Series A Investor. Pursuant to the 2020 Freight Series A Preferred Stock Purchase Agreement, the 2020 Freight Series A Investor agreed to invest an aggregate of $500 million in Freight Holding, which will occur over a number of closings, subject to customary closing conditions. On October 6, 2020, the initial closing occurred pursuant to the 2020 Freight Series A Preferred Stock Purchase Agreement and 2020 Freight Series A Investor invested $250 million in exchange for 124.7 million shares of Freight Series A preferred stock, representing approximately 8% ownership interest on a fully diluted basis. The 2020 Freight Series A Investor has the option to purchase additional shares in tranches of at least $50 million at a time at the initial purchase price for two years following initial closing up to an additional aggregate $250 million. This right to continue to invest at the initial price over two years is a forward obligation classified as a liability measured at fair value which was initially valued using a two-year discount rate and is immaterial. We will maintain majority ownership of the issued and outstanding capital stock of Freight Holding following such additional investment. Upon the passage of two years from initial close, the 2020 Freight Series A Investor must purchase and Freight Holding must issue any remaining unissued additional shares at the purchase price. The 2020 Freight Series A Investor holds two seats on the Freight Holding board of directors as of December 31, 2021. We do not attribute the pro rata share of the Freight Holding’s loss to the redeemable non-controlling interests in Series A Preferred shares of Freight Holding because these shares are entitled to a liquidation preference and therefore do not participate in losses that would cause their interest to be below the liquidation preference. Upon liquidation, these Freight Series A preferred stock are entitled to the greater of either (i) a 1.5x liquidation preference on their initial investment, as well as 6% continuously compounding cumulative dividends that will be paid before any distribution to common shareholders or (ii) the fair value of their investment (the “Freight Series A Liquidation Preference”). The dividend, along with any attributed prorated share of Freight Holding’s net income (if applicable), are included in net income (loss) attributable to non-controlling interests, net of tax in our consolidated statements of operations. The 2020 Freight Series A Investor’s Freight Series A preferred stock may be called by us at our option after the passage of five years at the Freight Series A Liquidation Preference. Beginning after three years, if a series of events occur including Freight Holding not consummating an IPO, 2020 Freight Series A Investor’s Freight Series A preferred stock could become redeemable at the Freight Series A Liquidation Preference upon the passage of five years. Upon redemption, the 2020 Freight Series A Investor’s Freight Series A preferred stock would be settled in either cash or Uber common shares at our option. In July 2021, we entered into a Series A preferred stock purchase agreement and sold shares of Freight Holding's Series A Preferred Stock to The Public Investment Fund, which is an investor in Uber, representing 4% ownership interest on a fully diluted basis at the time of the sale. As of December 31, 2021, the Freight Series A preferred stock held by the Public Investment Fund were classified as non-redeemable non-controlling interests as these shares of preferred stock are not subject to any mandatory redemption rights or redemption rights that are outside our control. Freight Series A-1 Preferred Stock In November 2021, Freight Holding entered into a 2021 Series A-1 Preferred Stock Purchase Agreement with Freight Series A-1 Investors. Pursuant to the 2021 Series A-1 Preferred Stock Purchase Agreement, the Freight Series A-1 Investors agreed to invest an aggregate of $550 million in Freight Holding in exchange for Freight Series A-1 preferred stock. The purchase and sale of the Freight Series A-1 preferred stock took place concurrently with the closing of the Transplace acquisition. Refer to Note 18 – Business Combinations for additional information on the Transplace acquisition. Freight Series A-1 Investors have basic rights and preferences which primarily include: one vote per share; conversion rights to common shares; 6% cumulative dividend preference and liquidation preference (a 1.0x liquidation preference of original issuance price plus cumulative unpaid dividends). The accruing dividends are compounding annually, and are only payable when dividends are declared by Freight Holding’s Board. The dividend, along with any attributed prorated share of Freight Holding’s net income (if applicable), are included in net income (loss) attributable to non-controlling interests, net of tax in our consolidated statement of operations. As of December 31, 2021, the Freight Series A-1 preferred stock held by the Freight Series A-1 Investors were classified as non-redeemable non-controlling interests as these shares of preferred stock are not subject to any mandatory redemption rights or redemption rights that are outside our control. Cornershop On July 6, 2020, we closed the acquisition of a 55% controlling ownership interest in CS-Global. Refer to Note 18 – Business Combinations for further information. As of December 31, 2020, the non-controlling interest in CS-Global was classified as redeemable non-controlling interest because it is subject to a put/call agreement which was not solely in our control to exercise. At each balance sheet date, the redeemable non-controlling interest was measured using a discounted cash flow methodology and the carrying value was adjusted if the fair value was higher than the carrying value. The initial fair value, as of the acquisition date of July 6, 2020, was $290 million. There were no fair value adjustments to CS-Global’s redeemable non-controlling interest during the year ended December 31, 2020. As of December 31, 2020, Cornershop’s financial results were consolidated in our consolidated financial statements given our majority ownership interest. On January 11, 2021, CS-Global exercised a call option and acquired 100% of the outstanding equity interest in CS-Mexico, which increased the redeemable non-controlling interest. In August 2021, we acquired the minority shareholders' interests in CS-Global in an all-stock transaction and CS-Global became a wholly-owned subsidiary of ours. We derecognized the carrying value of redeemable non-controlling interests in CS-Global of $1.3 billion. Refer to Note 18 – Business Combinations for further information.

We have several consolidated subsidiaries that have issued common stock and preferred stock or preferred units to third party investors, representing non-controlling interests. As of December 31, 2020 and 2021, the amounts of non-controlling interests represented by subsidiaries’ preferred units and preferred stock were $1.3 billion and $1.0 billion, respectively.

In July 2019, we closed a Preferred Unit Purchase Agreement with SoftBank, Toyota, and DENSO (collectively “the Investors”) for purchase by the Investors of Class A Preferred Units (“Preferred Units”) in Apparate. Apparate, a subsidiary of ours, issued 1.0 million Preferred Units at $1,000 per unit to the Investors for an aggregate consideration of $1.0 billion ($400 million from Toyota, $333 million from SoftBank, and $267 million from DENSO). As of December 31, 2020, the Preferred Units represented an aggregate 14.2% ownership interest in Apparate on an as-converted basis. As of December 31, 2020, we retained the remaining 85.8% ownership interest. SoftBank and Toyota are our existing investors.

At the option of the Investors, the Preferred Units are convertible into common units of Apparate, initially on a one-for-one basis but subject to potential adjustment, as defined by the Preferred Unit Purchase Agreement at any time. The Preferred Units are entitled to certain distributions, including primarily dividends which are payable in cash or in-kind (at Apparate's discretion), and accrue quarterly, compounded on the last day of each quarter at a 4.5% annual rate. The Preferred Units are entitled to distributions upon the occurrence of a sale or liquidation of Apparate representing an amount that is equal to the greater of (i) the original investment plus any accrued but unpaid amounts, and (ii) their share of distributions assuming conversion to common units of Apparate immediately prior to the sale or liquidation event. The quarterly dividend, along with any attributed prorated share of Apparate’s net income (if applicable), are included in net income (loss) attributable to non-controlling interests, net of tax in our consolidated statements of operations. The Preferred Units do not participate in net losses due to a liquidation preference.

Beginning on July 2, 2026, SoftBank has the option to put to us all, but not less than all, of its initial investment in Preferred Units at a price equal to the number of SoftBank’s Preferred Units multiplied by the greater of (i) the original investment plus any accrued but unpaid amounts per unit and (ii) the fair value of the Preferred Units at the time of conversion (the “Put/Call Price”). Beginning on July 2, 2026, we can call all, but not less than all, of the Preferred Units held by SoftBank at the Put/Call Price. We have the option to settle all, or a portion of, the Put/Call Price with its common stock and any remainder will be satisfied in cash. The put and call were determined to be embedded features within the SoftBank Preferred Units since they are not separately exercisable or legally detached from the SoftBank Preferred Units.

As of December 31, 2020, the SoftBank Preferred Units were classified as redeemable non-controlling interests in our consolidated financial statements and reported at the Put/Call Price which was determined as of the balance sheet date. The initial fair value of SoftBank’s Preferred Units was determined based on a hybrid method with the option pricing model as the primary methodology. This method used Level 3 fair value measurement inputs as well as an assumed equal probability of the occurrence of a liquidation or exit event. The significant unobservable inputs used in the initial fair value measurement include: volatility of 42%, time to liquidity of 5 years, and a discount for lack of marketability of 17%. A market approach was also used to corroborate the valuation derived from the hybrid method at issuance to evidence that the issuance price of the Preferred Units approximated their fair value. There was no fair value adjustment to SoftBank’s redeemable non-controlling interests during the year ended December 31, 2020.

In conjunction with the Preferred Unit Purchase Agreement discussed above, we entered into a three-year joint collaboration agreement among Toyota, DENSO, and Apparate to develop next-generation self-driving technology (the “ATG Collaboration Agreement”), which became effective as of the closing of the Preferred Unit Purchase Agreement in July 2019. Pursuant to the ATG Collaboration Agreement, Toyota would make cash payments to Apparate up to an aggregate of $300 million, payable in six semi-annual installments during the three-year term of the ATG Collaboration Agreement. The cash payments for each six-month period were contingent upon the mutual agreement between the parties on the development activities and milestones to be achieved in the next six months and the continuation of the ATG Collaboration Agreement.

During the years ended December 31, 2019 and 2020, we recognized $42 million and $100 million, respectively, as revenue under the ATG Collaboration Agreement.

On January 19, 2021, we completed the previously announced sale of our ATG Business to Aurora. As a result, our controlling interest and the non-controlling interests in the ATG Business were settled and ownership of the ATG Business transferred to Aurora. We derecognized the carrying value of non-controlling interests in the ATG Business of $1.1 billion, which included Toyota and DENSO non-redeemable non-controlling interests of $701 million and Softbank’s redeemable non-controlling interests of $356 million. Refer to Note 19 – Divestitures for further information.

As of December 31, 2020 and 2021, we owned 85% and 78%, respectively, of the issued and outstanding capital stock of our subsidiary Freight Holding, or 79% and 75%, respectively, on a fully-diluted basis if all common shares reserved for issuance under our Freight Holding employee incentive plan were issued and outstanding.

As of December 31, 2020 and 2021, the minority common stockholders ownership in Freight Holding is classified as a redeemable non-controlling interest, because it is redeemable on an event that is not solely in our control.

We attribute the pro rata share of the Freight Holding’s net income or loss available to holders of common stock to the redeemable non-controlling interests generated from common shares of Freight Holding based on the outstanding ownership of the minority shareholders of common shares during the period.

In October 2020, Freight Holding entered into a 2020 Freight Series A Preferred Stock Purchase Agreement with a 2020 Freight Series A Investor. Pursuant to the 2020 Freight Series A Preferred Stock Purchase Agreement, the 2020 Freight Series A Investor agreed to invest an aggregate of $500 million in Freight Holding, which will occur over a number of closings, subject to customary closing conditions.

The 2020 Freight Series A Investor has the option to purchase additional shares in tranches of at least $50 million at a time at the initial purchase price for two years following initial closing up to an additional aggregate $250 million. This right to continue to invest at the initial price over two years is a forward obligation classified as a liability measured at fair value which was initially valued using a two-year discount rate and is immaterial. We will maintain majority ownership of the issued and outstanding capital stock of Freight Holding following such additional investment. Upon the passage of two years from initial close, the 2020 Freight Series A Investor must purchase and Freight Holding must issue any remaining unissued additional shares at the purchase price. The 2020 Freight Series A Investor holds two seats on the Freight Holding board of directors as of December 31, 2021.

We do not attribute the pro rata share of the Freight Holding’s loss to the redeemable non-controlling interests in Series A Preferred shares of Freight Holding because these shares are entitled to a liquidation preference and therefore do not participate in losses that would cause their interest to be below the liquidation preference. Upon liquidation, these Freight Series A preferred stock are entitled to the greater of either (i) a 1.5x liquidation preference on their initial investment, as well as 6% continuously compounding cumulative dividends that will be paid before any distribution to common shareholders or (ii) the fair value of their investment (the “Freight Series A Liquidation Preference”).

Beginning after three years, if a series of events occur including Freight Holding not consummating an IPO, 2020 Freight Series A Investor’s Freight Series A preferred stock could become redeemable at the Freight Series A Liquidation Preference upon the passage of five years. Upon redemption, the 2020 Freight Series A Investor’s Freight Series A preferred stock would be settled in either cash or Uber common shares at our option.

In July 2021, we entered into a Series A preferred stock purchase agreement and sold shares of Freight Holding's Series A Preferred Stock to The Public Investment Fund, which is an investor in Uber, representing 4% ownership interest on a fully diluted basis at the time of the sale. As of December 31, 2021, the Freight Series A preferred stock held by the Public Investment Fund were classified as non-redeemable non-controlling interests as these shares of preferred stock are not subject to any mandatory redemption rights or redemption rights that are outside our control.

Pursuant to the 2021 Series A-1 Preferred Stock Purchase Agreement, the Freight Series A-1 Investors agreed to invest an aggregate of $550 million in Freight Holding in exchange for Freight Series A-1 preferred stock. The purchase and sale of the Freight Series A-1 preferred stock took place concurrently with the closing of the Transplace acquisition.

On July 6, 2020, we closed the acquisition of a 55% controlling ownership interest in CS-Global. Refer to Note 18 – Business Combinations for further information. As of December 31, 2020, the non-controlling interest in CS-Global was classified as redeemable non-controlling interest because it is subject to a put/call agreement which was not solely in our control to exercise. At each balance sheet date, the redeemable non-controlling interest was measured using a discounted cash flow methodology and the carrying value was adjusted if the fair value was higher than the carrying value. The initial fair value, as of the acquisition date of July 6, 2020, was $290 million. There were no fair value adjustments to CS-Global’s redeemable non-controlling interest during the year ended December 31, 2020. As of December 31, 2020, Cornershop’s financial results were consolidated in our consolidated financial statements given our majority ownership interest.

On January 11, 2021, CS-Global exercised a call option and acquired 100% of the outstanding equity interest in CS-Mexico, which increased the redeemable non-controlling interest.
