Microsoft’s OpenAI partnership could face EU antitrust probe: Report

Microsoft’s $13 billion investment in OpenAI could face an EU antitrust investigation as regulators are building the case for such a move, people familiar with the matter said on Thursday.

Microsoft’s OpenAI partnership, together with those between Alphabet, Amazon and Anthropic, have triggered scrutiny on both sides of the Atlantic as antitrust enforcers seek to understand how these deals affect competition.

The people said the European Union antitrust regulator had decided not to investigate the partnership under EU merger rules, but that Microsoft could still face an antitrust investigation.
