Paris-based artificial intelligence company Mistral AI has closed a €3 billion funding round led by Samsung Electronics, nearly doubling its valuation to more than €21 billion. The company describes it as the largest equity fundraising ever completed by a European technology firm.
The Series D round, announced on Tuesday, also includes the EU-backed Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity. This comes three years after the company's founding, and marks a sharp acceleration in its growth trajectory.
Mistral was valued at €11.7 billion in 2025 after a €1.7 billion Series C led by Dutch chipmaker ASML. The new round means the company has almost doubled its valuation in just over a year, a sign of the intense investor appetite for European AI champions.
Building infrastructure, not just algorithms
Much of the fresh capital will go into physical assets rather than software development. CEO Arthur Mensch said the funding will support the construction of data centres and computing capacity that Mistral can rent to other businesses, while also ensuring the company's own autonomy.
"Long term, the plan is to fully rely on capacity that we are building ourselves, and so that means that the amount of compute that we own is going to grow around 100% in the next five years," Mensch said, adding that the company would train "bigger and faster models."
Mistral is already spending €4 billion on data centres across France and Europe, with one facility operating outside Paris and another under construction in Sweden. In March, the company raised additional debt financing for the same purpose, and Microsoft has agreed to fund capacity from its European network, built around thousands of Nvidia chips.
Both Microsoft and Nvidia are also investors in Mistral, with Nvidia increasing its stake in this round. The company says more than 125 enterprises across 20 countries use its technology, and it projects that it will pass €1 billion in annual recurring revenue by the end of 2026.
Europe still lags in the AI race
Despite this milestone, Europe continues to critically lag behind in the global AI race. Mistral's valuation remains far below those of OpenAI and Anthropic, and the continent's wider AI sector is a fraction of the American one, with enterprise adoption across the bloc running at around 13.5%.
Other European contenders exist but are smaller. Germany's Aleph Alpha focuses on government and regulated industries rather than competing at the frontier, while Helsing has grown quickly in defence applications, and Switzerland's Apertus offers fully open models and training data.
Brussels is trying to close the gap. The InvestAI initiative carries a €200 billion headline commitment, and in July the European Commission opened tenders for up to seven AI gigafactories, aiming to unlock more than €30 billion in investment, though those sites are not expected to operate until next year or 2028. Thirteen smaller AI factories are already being built across seven EU countries.
The AI Act became applicable in August, but its toughest obligations were pushed back by the digital omnibus agreed in May, with high-risk rules now landing in December 2027 and August 2028. Brussels framed the delay as making the policy more innovation-friendly.
Mistral's record round is a clear signal that European investors are willing to back ambitious AI projects, but the gap with the US remains wide. Whether the continent can translate this momentum into a competitive ecosystem will depend on sustained investment, regulatory clarity, and the ability to retain talent.
