The Federal Trade Commission (FTC) has lost its appeal of a ruling in its case against Microsoft’s $68.7 billion acquisition of Activision Blizzard. In 2023, the FTC requested a preliminary injunction to prevent the companies from finalizing the deal while its legal challenge to the acquisition from 2022 was in progress.

A federal appeals court on Wednesday rejected a legal challenge by the Federal Trade Commission to Microsoft's $69 billion purchase of “Call of Duty” maker Activision Blizzard.

After the FTC lost their court battle, Microsoft Corporation has claimed full ownership of game developer Activision Blizzard. The US Federal Trade Commission went to legal war against Microsoft after it bought Activision Blizzard in 2023.
