Mistral AI raises €3 billion Series D led by Samsung

Mistral AI closed a €3 billion Series D at a post-money valuation exceeding €21 billion, described as the largest equity fundraising by a European technology company. Samsung Electronics led, with co-leads including the EU-backed Scaleup Europe Fund; proceeds target compute scaling, infrastructure, and commercial expansion of its open-weight and sovereign AI offering. The round nearly doubles the prior valuation and reinforces European capital commitment to competitive AI capacity.
