Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to provisions for transaction losses, legal contingencies, income taxes, revenue recognition, stock-based compensation, investments including level 3 investments in Gmarket Global LLC (“Gmarket”), warrants and the recoverability of goodwill and intangible assets. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying financial statements are consolidated and include the financial statements of eBay Inc., our wholly and majority-owned subsidiaries and variable interest entities (“VIE”) where we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Minority interests are recorded as a noncontrolling interest. A qualitative approach is applied to assess the consolidation requirement for VIEs. Generally, investments in entities where we hold at least a 20% ownership interest and have the ability to exercise significant influence, but not control, over the investee are accounted for using the equity method of accounting, including those in which the fair value option has been elected. For equity method investments, our share of the investees’ results of operations is included in gain (loss) on equity investments and warrant, net and investment balances are included in long-term investments. For equity investments under the fair value option, the change in fair value of the investment is included in gain (loss) on equity investments and warrant, net and investment balances are included in long-term investments, other than our equity interest in Adevinta ASA (“Adevinta”) which is included in the short-term assets section on the condensed consolidated balance sheet. Investments in entities where we hold less than a 20% ownership interest are generally accounted for as equity investments to be measured at fair value or, under an election, at cost if it does not have readily determinable fair value, in which case the carrying value would be adjusted upon the occurrence of an observable price change in an orderly transaction for identical or similar instruments or impairment. Upon the transfer of our Classifieds business to Adevinta in 2021, shares in Adevinta were included as part of total consideration received under the definitive agreement. The equity interest in Adevinta is accounted for under the fair value option. Additionally, upon completion of the sale of 80.01% of the outstanding equity interests of eBay Korea LLC (“eBay Korea”) to Emart Inc. (“Emart”) in 2021, we retained 19.99% of the outstanding equity interests of the new entity, Gmarket, which is accounted for under the fair value option. Subsequent changes in fair value for these equity investments are included in gain (loss) on equity investments and warrant, net on our consolidated statement of income. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2022. We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In June 2022, the Financial Accounting Standards Board (“FASB”) issued new guidance to clarify the fair value measurement guidance for equity securities subject to contractual restrictions that prohibit the sale of an equity security. Further, the guidance introduces new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value. The standard will be effective for annual reporting periods beginning after December 15, 2023, including interim reporting periods within those fiscal years. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
