Mistral AI

The European Commission opened a preliminary review in March 2024 into whether Microsoft's €15M investment in Mistral AI constituted a reportable concentration under EU merger rules. Green MEPs called the deal a "Trojan horse" for Big Tech consolidation of the European AI sector — particularly given Mistral's prior role lobbying to soften EU AI Act regulations on foundation models. The EC ultimately concluded the deal did not meet merger notification thresholds but the episode highlighted tensions between European AI sovereignty and Big Tech investment.

Mistral AI received public support from French President Emmanuel Macron and benefits from close ties with the French government, positioning as a national champion.

Mistral lobbied against strict EU AI Act regulations on foundation models in late 2023, arguing they would harm European AI competitiveness. The company supports lighter-touch governance.

Mistral AI released open-weight models (Mistral 7B, Mixtral 8x7B) under permissive licenses, positioning itself as the European open-source counterweight to OpenAI.
