CMA case Microsoft / Activision Blizzard merger inquiry: Microsoft / Activision Blizzard

The United Kingdom Competition and Markets Authority blocked Microsoft's acquisition of Activision Blizzard on 26 April 2023 (case Microsoft / Activision Blizzard merger inquiry).[1]

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.
