On October 13, 2023, Microsoft completed its $75.4 billion acquisition of Activision Blizzard, marking the largest deal in video game history and one of the most significant in the tech sector. This acquisition brings iconic franchises such as Call of Duty, World of Warcraft, Diablo, Overwatch, and Candy Crush under Microsoft’s umbrella, significantly enhancing its gaming portfolio and positioning it as a formidable competitor in the global gaming market.
The acquisition aligns with Microsoft’s strategy to expand its presence in the gaming industry and accelerate growth in its Xbox and Game Pass platforms. By integrating Activision Blizzard’s extensive library of games into its ecosystem, Microsoft aims to offer a more diverse and robust gaming experience, potentially attracting a broader user base and increasing subscription revenues.
Phil Spencer, CEO of Microsoft Gaming, emphasized the company’s commitment to making Activision Blizzard’s games more accessible: “Today we start the work to bring beloved Activision, Blizzard, and King franchises to Game Pass and other platforms. We’ll share more about when you can expect to play in the coming months.”
The path to finalizing the acquisition was fraught with regulatory scrutiny. In the United States, the Federal Trade Commission (FTC) filed a lawsuit in December 2022 to block the deal, citing antitrust concerns. However, a federal judge denied the FTC’s request for a preliminary injunction in July 2023, allowing the acquisition to proceed. The FTC’s appeal was subsequently denied by an appellate court, and the agency eventually dropped its opposition in May 2025.
In the United Kingdom, the Competition and Markets Authority (CMA) initially opposed the deal due to concerns about its impact on cloud gaming competition. To address these concerns, Microsoft agreed to transfer the cloud streaming rights for Activision Blizzard’s games to Ubisoft for a period of 15 years. This concession satisfied the CMA, which approved the acquisition in October 2023.
With the acquisition, Microsoft has become the third-largest gaming company by revenue, trailing only Tencent and Sony. The deal significantly bolsters Microsoft’s gaming portfolio, adding a wealth of popular franchises and expanding its reach into mobile gaming through King, the developer behind Candy Crush.
The integration of Activision Blizzard’s titles into Xbox Game Pass is expected to enhance the value proposition of Microsoft’s subscription service, potentially attracting new subscribers and increasing engagement among existing users. However, Microsoft has indicated that some recent releases, such as Call of Duty: Modern Warfare 3 and Diablo IV, will not be immediately available on Game Pass.
As part of the acquisition, Activision Blizzard CEO Bobby Kotick agreed to remain in his role through the end of 2023 to facilitate the transition. He reported directly to Phil Spencer during this period. Following the completion of the deal, Microsoft initiated organizational changes to align its gaming division, resulting in the layoff of approximately 650 employees in September 2024. These layoffs primarily affected corporate and support roles, with no impact on game development studios or projects.
Microsoft’s acquisition of Activision Blizzard represents a significant shift in the gaming industry, consolidating a vast array of popular franchises under one corporate entity. The move underscores Microsoft’s commitment to expanding its gaming footprint and enhancing its Game Pass offerings. As the company integrates Activision Blizzard’s assets and navigates the evolving regulatory landscape, the long-term impact of this acquisition on competition, innovation, and consumer choice in the gaming industry will continue to unfold.
