French AI company Mistral AI announced on September 8 a €3 billion Series D led by Samsung Electronics, at a post-money valuation above €21 billion. According to the company itself, it's the largest capital round ever closed by a European tech company.
Samsung Electronics led the round, with EQT's Scaleup Europe fund and existing investor PSG Equity as co-leads. Participants also include U.S. investors already present from earlier rounds — a16z, Nvidia, and Salesforce Ventures — alongside new backers such as Advent, BlackRock, and the Grand Duchy of Luxembourg itself as a state investor. The valuation nearly doubles the €11.7 billion Mistral reached in its Series C in September 2025, just a year earlier.
French President Emmanuel Macron described the funding as reflecting France and South Korea's shared goal of "building a third way in AI," an explicit reference to reducing dependence on U.S. infrastructure. Mistral plans to use the capital to scale compute, build out its own infrastructure — with a target of 1 gigawatt of European capacity by 2030 — and accelerate commercial expansion, which already covers 20 countries with a focus on government and enterprise customers seeking sovereign control over their AI models.
