Mistral AI has secured a Series D round of €3 billion, making it the largest equity funding round for any European tech company. The round was led by Samsung Electronics, with the Scaleup Europe Fund, managed by EQT, and PSG Equity acting as co-leads.
The investment round includes participation from new investors such as Advent, BlackRock, and the Grand Duchy of Luxembourg. Existing backers, including Nvidia, ASML, and a16z, also contributed to the round.
The company's valuation has increased to over €21 billion, roughly doubling from its previous valuation of about €12 billion when ASML invested €1.3 billion in September 2025.
To support its own data centers, Mistral AI took out a loan of $830 million in March. This financial strategy focuses on infrastructure development to reduce dependency on external providers.
The company currently operates in 20 countries across thes Europe, serving more than 125 companies, including HSBC, ASML, and Airbus. Since early 2026, it has seen growth driven by European clients seeking alternatives to US-based AI providers.
