Invitation to comment: closed
8 December 2023: The CMA is considering whether it is or may be the case that Microsoft’s partnership with OpenAI, or any changes thereto, has resulted in the creation of a relevant merger situation under the merger provisions of the Enterprise Act 2002 and, if so, whether the creation of that situation may be expected to result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.
