Microsoft-Activision (2022-2023): the $68.7B gaming acquisition that closed after 21 months of antitrust review
On January 18, 2022, Microsoft announced an all-cash agreement to acquire Activision Blizzard for $68.7 billion — the largest acquisition in Microsoft’s history and the largest in the gaming industry. The deal closed on October 13, 2023, after one of the most extensive antitrust reviews of a software acquisition on record. The FTC sued to block in December 2022 and lost in court in July 2023. The UK Competition and Markets Authority blocked the deal in April 2023, then accepted a restructured version in October 2023 after Microsoft divested cloud-streaming rights for Activision games outside the EEA to Ubisoft for 15 years. The European Commission cleared in May 2023 with behavioral remedies. The case is now the most fully-documented example of how a major software acquisition can survive a multi-jurisdiction adverse-regulator environment through structural remedies.

- Takeaway: Major tech M&A faces increasing regulatory scrutiny across multiple jurisdictions producing complex approval processes.
- Takeaway: Structural remedies can resolve specific regulator concerns while preserving core deal value.
- Takeaway: Approval timelines for major tech M&A have extended significantly compared to historical norms.
Microsoft-Activision acquisition — the four-step story
Microsoft-Activision by the numbers
Quick facts
Why Microsoft wanted Activision
Microsoft’s strategic case for Activision had three pieces. First, content scale: Activision owned Call of Duty, World of Warcraft, Candy Crush, Diablo, and Overwatch — some of the largest active gaming franchises in the world. Owning the publisher gave Microsoft direct control of pipeline-defining content. Second, mobile: King (the Candy Crush developer, owned by Activision) was the piece of the puzzle that gave Microsoft a meaningful mobile-gaming position to complement its console and PC franchises. Third, cloud and subscription: Game Pass — Microsoft’s subscription-gaming service — needed AAA exclusives to compete with PlayStation and other streaming services, and Activision’s catalog would feed that.
The deal was announced January 18, 2022 at $95/share in all cash — a roughly 45% premium to Activision’s pre-announcement price. The size made it the largest software acquisition ever and immediately placed it at the center of the 2022-2023 antitrust wave.
The 21-month regulatory process
The FTC under Chair Lina Khan filed an administrative complaint to block the deal in December 2022, then sought a preliminary injunction in federal court in June 2023. The FTC lost in court in July 2023 (Judge Jacqueline Scott Corley denied the injunction request), and the FTC’s subsequent appeals were not resolved before the deal closed. Microsoft and Activision had committed to behavioral undertakings on Call of Duty availability across platforms, which the court found materially reduced the competition concerns the FTC had alleged.
The UK CMA was the harder regulator. On April 26, 2023, the CMA published a Phase 2 prohibition decision focused specifically on cloud-gaming — concluding that Microsoft’s ownership of Activision content combined with its Xbox Cloud Gaming service would substantially lessen competition in the emerging cloud-gaming market. The decision blocked the deal in its original form. Microsoft restructured: in August 2023 it announced a separate transaction to sell the cloud-streaming rights for current and future Activision games to Ubisoft for 15 years (outside the European Economic Area). The CMA accepted the restructured version on October 13, 2023 and the deal closed the same day.
The European Commission cleared the deal on May 15, 2023 with behavioral remedies. Microsoft committed to license cloud-streaming rights for current and future Activision PC and console games to consumer cloud-streaming services free-of-charge in the EEA for 10 years. The EC accepted those commitments where the CMA did not.
How the cloud-streaming-rights remedy worked
The structural remedy that ultimately closed the deal was the Ubisoft cloud-streaming-rights divestiture. The transaction transferred to Ubisoft the cloud-streaming rights for all current and future Activision PC and console games for 15 years, in markets outside the EEA. Inside the EEA the EC-accepted behavioral remedy (compulsory free licensing of cloud-streaming rights) applied instead. The combination addressed the CMA’s specific cloud-gaming theory of harm.
For Ubisoft, the transaction was a meaningful business win — access to cloud-streaming rights for the Call of Duty and Activision catalog gave Ubisoft’s own cloud service real strategic content. For Microsoft, the divestiture cost was structural revenue (Microsoft would not receive direct cloud-streaming revenue from those games outside the EEA), but the cost was modest relative to the value of closing the deal at the headline terms.
How RGM thinks about this for M&A and regulatory strategy
When clients ask about closing large software M&A in the post-2022 antitrust environment, Microsoft-Activision is the structural example. Three things made the deal close where many similar deals (Figma-Adobe, Spirit-JetBlue) did not. First, Microsoft proactively offered structural remedies before regulators demanded them — the 10-year Call of Duty access commitments to PlayStation, the cloud-streaming licensing commitments — which reduced the regulators’ ability to argue that voluntary remedies were inadequate. Second, Microsoft demonstrated willingness to do real divestitures (not just behavioral commitments) when the UK CMA prohibition required them. Many buyers will not divest structurally; Microsoft did and the deal closed. Third, Microsoft litigated effectively against the FTC where it had the better case and offered remedies to the regulators where the case was weaker. The asymmetric strategy — fight where you can win, remediate where you cannot — is the playbook for this environment.
The pattern depends on the buyer being financially and strategically able to absorb the divestiture cost. Buyers that need every dollar of the synergy case to justify the deal price do not have the optionality Microsoft had. For most clients, the practical takeaway is that closing a controversial deal now requires (a) modeling the divestiture / behavioral-remedy cost as a real cost in the deal economics from day one, (b) litigating with senior counsel where the antitrust case is winnable, and (c) accepting that the timeline will be 18-24 months rather than 6-12 months. The Figma-Adobe contrast is instructive: that deal failed in part because the buyer was not willing or able to absorb the cost of structural remedies the regulators wanted.
Frequently asked questions
How long did the regulatory process take?
Twenty-one months from announcement (January 18, 2022) to closing (October 13, 2023). For reference, most non-controversial software acquisitions of comparable size close in 6-9 months. The Microsoft-Activision timeline reflects the high level of regulatory pushback and the structural-remedy negotiation needed in the UK.
What did Microsoft give up to close the deal?
The largest structural concession was the 15-year cloud-streaming-rights divestiture to Ubisoft outside the EEA. Microsoft also made 10-year behavioral commitments to keep Call of Duty on PlayStation and Nintendo platforms and to license Activision games to consumer cloud-streaming services free in the EEA. The divestiture cost is real but modest relative to the deal economics.
Why did the FTC lose?
Judge Corley’s July 2023 ruling found that the FTC had not shown the substantial likelihood of competitive harm that a preliminary injunction requires. The behavioral remedies Microsoft had already committed to (Call of Duty availability across platforms) materially reduced the substantive harm theory. The FTC’s appeals continued but did not prevent the closing.
Why was the UK CMA the binding constraint?
The CMA’s cloud-gaming theory of harm was a forward-looking innovation theory: even where current cloud-gaming competition was modest, the merger would entrench Microsoft’s position in an emerging market. The CMA did not accept behavioral remedies and required structural divestiture. The CMA’s remedy authority is broad enough that without the Ubisoft divestiture, Microsoft could not have closed in the UK and would not have closed globally.
What is the broader lesson for software M&A?
Closing controversial software M&A in 2022-2024 has required (1) proactive remedies before regulators demand them, (2) willingness to do structural divestitures where behavioral remedies will not satisfy regulators, and (3) strong legal capability to litigate where the antitrust case is winnable. Buyers who cannot or will not absorb the divestiture cost should expect deals to fail (Figma-Adobe being the contrasting example).
