FTC Finally Drops Challenge to Microsoft’s 2023 Acquisition of Activision Blizzard

Just days after losing its two-year-old objection to Microsoft’s acquisition of Activision Blizzard, the U.S.’s Federal Trade Commission (FTC) has officially dropped its case.

The FTC’s appeal to block Microsoft’s $69 billion deal to acquire the company behind Call of Duty was denied by San Francisco’s 9th U.S. Circuit Court of Appeals on May 7, further cementing the purchase that was originally announced in late 2022. It was a move decided by a three-judge panel that brought an end to the FTC’s questioning of the July 2023 decision to allow Microsoft to finalize its purchase.

As we summarized at the time, Microsoft’s acquisition of Activision Blizzard has faced scrutiny from across the board for more than three years, both in the U.S. and worldwide, with some parties concerned that an acquisition would see popular franchises like Call of Duty become Xbox exclusives. Microsoft confirmed it had no interest in barring certain franchises behind lengthy exclusivity periods, and sold Activision-Blizzard’s cloud gaming rights to Ubisoft to satisfy the UK’s Competition and Markets Authority (CMA) objections.

While challenges continued to arise throughout 2023, Microsoft was finally able to complete its purchase of Activision Blizzard in October of that same year.

The FTC’s appeal could have presented a late roadblock to continuing. However, as reported by The Verge, the Commission has now dismissed its complaint entirely, stating in a brief filing issued on May 22: “The Commission has determined that the public interest is best served by dismissing the administrative litigation in this case.”

“On May 7, 2025, the Ninth Circuit affirmed the decision of the United States District Court for the Northern District of California, FTC v. Microsoft Corp. […] denying the Commission’s application for a preliminary injunction to block the acquisition of Activision Blizzard, Inc. by Microsoft Corp.

“Accordingly, it is hereby ordered that the Complaint in this matter be, and it hereby is, Dismissed.”
