UK Regulator Declines Investigation into Microsoft-Mistral AI Partnership

The Competition and Markets Authority found no grounds for probing the $16 million investment, citing insufficient influence over Mistral AI's policies.

The CMA determined Microsoft's investment did not qualify as a merger under UK law.
Microsoft's $16 million stake in Mistral AI aimed to integrate AI models into Azure services.
The regulator sought public comments before concluding no substantial competition concerns.
Other AI-related partnerships, including Amazon-Anthropic, remain under CMA review.
Experts suggest strict antitrust rulings could impact future AI investments and innovation.
