Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Consolidation and Presentation	1. Description of Business and Basis of Consolidation and Presentation Activision Blizzard, Inc. is a leading global developer and publisher of interactive entertainment content and services. We develop and distribute content and services on video game consoles, personal computers (“PCs”), and mobile devices. We also operate esports leagues and offer digital advertising within some of our content. The terms “Activision Blizzard,” the “Company,” “we,” “us,” and “our” are used to refer collectively to Activision Blizzard, Inc. and its subsidiaries. Merger Agreement On January 18, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Microsoft Corporation (“Microsoft”) and Anchorage Merger Sub Inc. (“Merger Sub”), a wholly owned subsidiary of Microsoft. Subject to the terms and conditions of the Merger Agreement, Microsoft agreed to acquire the Company for $95.00 per issued and outstanding share of our common stock, par value $0.000001 per share, in an all-cash transaction. Pursuant to the terms of the Merger Agreement, our acquisition will be accomplished through the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Microsoft. As a result of the Merger, we will cease to be a publicly traded company. We have agreed to various customary covenants and agreements, including, among others, agreements to conduct our business in the ordinary course during the period between the execution of the Merger Agreement and the effective time of the Merger. We do not believe these restrictions will prevent us from meeting our debt service obligations, ongoing costs of operations, working capital needs or capital expenditure requirements. If the Merger Agreement is terminated under certain specified circumstances, we or Microsoft will be required to pay a termination fee. We will be required to pay Microsoft a termination fee of approximately $2.27 billion under specified circumstances, including termination of the Merger Agreement due to our material breach of representations, warranties, covenants or agreements in the Merger Agreement. Microsoft will be required to pay us a reverse termination fee under specified circumstances, including termination of the Merger Agreement due to a permanent injunction arising from Antitrust Laws (as defined in the Merger Agreement) when we are not then in material breach of any provision of the Merger Agreement and if certain other conditions are met, in an amount equal to $3.0 billion if the termination notice is provided at any time after April 18, 2023. For additional information related to the Merger Agreement, please refer to Part I Item 1 “Business” of our Annual Report on Form 10-K for the year ended December 31, 2022, and other relevant materials in connection with the proposed transaction with Microsoft that we will file with the SEC and that will contain important information about the Company and the Merger. On December 8, 2022, the United States Federal Trade Commission (the “FTC”) issued an administrative complaint against the Company and Microsoft alleging that the Company and Microsoft executed the Merger Agreement in violation of Section 5 of the FTC Act, as amended, 15 U.S.C. § 45, which, if consummated, would violate Section 7 of the Clayton Act, as amended, 15 U.S.C. § 18 and Section 5 of the FTC Act, as amended, 15 U.S.C. § 45. For more information regarding the FTC complaint regarding the pending Merger, see Note 13 of the condensed consolidated consolidated financial statements. On April 26, 2023, the United Kingdom Competition and Markets Authority ("CMA") announced a decision to block the Merger, stating that competition concerns arose in relation to cloud gaming and that Microsoft’s remedies addressing any concerns in cloud gaming were not sufficient. Microsoft has announced its decision to appeal the CMA’s ruling, and Activision Blizzard intends to fully support Microsoft’s efforts on this appeal. The parties continue to fully engage with other regulators reviewing the transaction to obtain required regulatory approvals.

Basis of Consolidation and Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the SEC and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. Accordingly, certain notes or other information that are normally required by U.S. GAAP have been condensed or omitted if they substantially duplicate the disclosures contained in our annual audited consolidated financial statements. Additionally, the year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Accordingly, the unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022. The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. In the opinion of management, all adjustments considered necessary for the fair statement of our financial position and results of operations in accordance with U.S. GAAP (consisting of normal recurring adjustments) have been included in the accompanying unaudited condensed consolidated financial statements. Actual results could differ from these estimates and assumptions. The accompanying condensed consolidated financial statements include the accounts and operations of the Company. All intercompany accounts and transactions have been eliminated. Certain amounts in the prior year condensed consolidated financial statements have been reclassified to conform to the current year presentation.
