United Kingdom Competition and Markets Authority — Microsoft / Activision Blizzard merger inquiry
Blocked · Phase 2
The Competition and Markets Authority blocked Microsoft's acquisition of Activision Blizzard in April 2023, finding it would harm competition in cloud gaming. It was the only major regulator to prohibit the deal outright, and the decision was widely reported as putting the transaction in doubt worldwide. The case was closed in August 2023 once the parties restructured.
