Microsoft’s $75 billion acquisition of Activision Blizzard cleared its final U.S. regulatory hurdle as the FTC dropped its challenge, capping a nearly two-year legal battle.

The Republican-controlled Federal Trade Commission is abandoning a Biden-era effort to block Microsoft’s purchase of Call of Duty video game maker Activision Blizzard. In an order issued Thursday, the FTC said it had determined that “the public interest is best served by dismissing the administrative litigation in this case.

This is the end of the FTC’s fight to block a $68.7 billion deal that saw Microsoft purchase Activision Blizzard. The deal closed in 2023.
