Mistral is betting on what it calls "sovereign AI." Simple idea: open-weight models that enterprises can download and tailor on their own servers, while keeping data in-house. The company closed its Series C round in September 2025 at a valuation of €11.7 billion. Less than a year later, that figure has jumped nearly 80% to above €21 billion.
Right now, Mistral operates in 20 countries and works with more than 125 global enterprise clients.
