French AI Startup Mistral Raises Three Billion Euros in Europe's Largest Funding Round

Mistral said it operates in 20 countries and serves more than 125 enterprises, including Airbus, ASML and HSBC, illustrating the company’s existing commercial reach.
The company is expanding its computing footprint through both owned infrastructure and outside capacity: it is building its first data center in France and signed a July agreement with Microsoft to provide computing capacity and distribute Mistral models to Microsoft’s U.S. customers.
Mistral CEO Arthur Mensch said the company plans to substantially increase the amount of computing capacity it owns over the next five years and use that infrastructure to train larger and faster models.
The financing included new backing from Advent, BlackRock-managed funds and the Grand Duchy of Luxembourg, while existing shareholders such as Andreessen Horowitz, Bpifrance, DST Global, Index Ventures, Lightspeed and Salesforce Ventures also participated.
The announcement coincided with South Korean President Lee Jae Myung’s state visit to France, during which he was scheduled to meet French President Emmanuel Macron; analyst Lian Jye Su said Samsung’s investment could give the company greater access to European markets and “further diversify its commercial touchpoints.”
French AI startup Mistral has raised €3 billion in its largest funding round, nearly doubling its valuation to more than €21 billion. Yahoo Finance reports the round was led by Samsung Electronics, the EU-backed Scaleup Europe Fund, and existing investor PSG Equity, making it Europe's biggest tech financing. The company plans to use the capital to expand AI research, build data centers, and grow its international operations.
Mistral positions itself as a "sovereign" AI alternative, letting businesses and governments keep control of their data and run systems on their own servers. TMCnet notes the company already serves more than 125 enterprises including Airbus, ASML, and HSBC across 20 countries. The investment reflects growing European efforts to compete with U.S. AI giants like OpenAI and Anthropic.
Samsung's decision to lead the round wasn't purely financial. Arise.tv reports the investment creates a strategic partnership that could expand Mistral's reach to European customers and support AI applications in Samsung's semiconductor business. The timing aligned with South Korean President Lee Jae Myung's state visit to France, signaling Seoul's commitment to European tech partnerships.
Mistral is making aggressive moves to own its own computing power. The company is building its first data center in France and signed a July agreement with Microsoft for additional computing capacity and model distribution to U.S. customers. Morningstar reports CEO Arthur Mensch plans to substantially increase owned infrastructure over the next five years to train larger, faster models.
Beyond Samsung, the round drew backing from Advent, BlackRock-managed funds, and Luxembourg's government. Morning Chronicle notes existing investors like Andreessen Horowitz, Bpifrance, DST Global, Index Ventures, Lightspeed, and Salesforce Ventures also participated. This diverse investor base reflects confidence in Mistral's "sovereign AI" pitch during a period of rising European concern about data security and tech independence.
