Funding Market: Mistral Secures €3B Series D for Sovereign AI
Mistral AI, a Paris-based company, raised €3 billion (~$3.5 billion) in a Series D round, reaching a post-money valuation exceeding €21 billion (~$24 billion), marking the largest equity financing ever by a European tech firm. Led by Samsung Electronics, with co-leads EQT's Scaleup Europe Fund and PSG Equity, the round attracted new investors Advent, BlackRock-managed funds, and Luxembourg, plus existing backers ASML, NVIDIA, Andreessen Horowitz, and others. The funds will advance R&D, computing capacity, and global expansion, shifting focus toward AI infrastructure, data centers, and sovereign compute via Mistral Compute. This intensifies competition with European neocloud rivals Nebius and Nscale. Notably, for the first time, a non-European entity leads the round, possibly indicating a broader coalition of middle powers in European AI sovereignty. Mistral serves over 125 enterprises across 20 countries, including Airbus and HSBC, targets 1 GW data centers by 2030, and expects ARR to exceed $1 billion this year.
Major funding round for a leading European AI company, indicating strong investor confidence and impacting the AI infrastructure landscape.
