Mistral raises €3B to make sovereign, open-weight AI the technology frontier
Mistral, the French AI startup, has raised €3 billion in a Series D round led by Samsung Electronics, valuing the company at over €21 billion. This is the largest equity fundraising ever by a European tech company, just three years after launch. The funds will expand frontier research, scale compute capacity, and accelerate commercial growth. Mistral now operates in 20 countries, supporting enterprises like Airbus, ASML, and HSBC. Its full-stack approach—open-weight models, infrastructure, and products—aims to give organizations control over data, models, and compute, positioning Mistral as the sovereign AI layer.
Mistral is the only AI company in the world building the full stack required to answer that question: open-weight models, the infrastructure and the compute capacity they run on, and the products that bring them into production; ensuring that customers are never locked into a single vendor's roadmap, pricing or availability.
