Mistral AI Closes €3B Series D at €21B+ Valuation, Led by Samsung

French AI company Mistral AI has officially closed a €3 billion (approx. $3.58B) Series D at a post-money valuation above €21 billion (approx. $24.39B), led by Samsung Electronics with participation from an EQT fund. The round, confirmed around September 13, validates earlier funding rumors and is widely described as the largest equity raise ever by a European tech company—achieved only three years after the company's founding.

Confirmed

• €3B Series D, post-money valuation above €21B (approx. $24.39B), three years after founding
• Led by Samsung Electronics, with an EQT fund participating
• Described as the largest equity financing round in European tech history
• Funds earmarked for expanding its sovereign, open-weight AI stack and global footprint

Why it matters

• @thione notes this is one of the largest financings under the "sovereign AI" narrative for a leading European AI company, signaling Europe's bet on sovereign, open-weight models against US closed-model giants
• Investor Anjney Midha's recollection of early contact with Mistral's co-founders two years ago (as relayed by @AccBalanced) underscores how quickly the startup rose to become Europe's AI flagship
• Samsung's lead investment also reflects Asian tech giants backing Europe's open-weight camp
