Mistral’s funding round has closed at more than €21bn. Samsung Electronics led the €3bn Series D, which the Paris company calls the largest equity raise by a European technology firm to date.
The round’s co-leads point to where that capital came from. PSG Equity, a backer since Mistral’s Series C, returned for this one. Joining it is the Scaleup Europe Fund, the roughly €5bn vehicle the European Commission created. Its goal: keep the continent’s largest tech companies from raising money abroad.
EQT was picked in May 2026 to manage that fund, and this Mistral funding round is its first major deployment.
Mistral funding round nearly doubles the company’s valuation
Mistral closed a €1.7bn Series C at an €11.7bn valuation in September 2025, led by ASML. Twelve months later, the valuation has nearly doubled. TNW reported over the summer that Samsung was negotiating around €20bn; the final figure landed above that.
Both of Mistral’s last two rounds were led by hardware manufacturers rather than software investors. ASML builds the lithography machines that make advanced chips possible, while Samsung makes the chips and memory that go into them. For a company arguing that AI needs to run on infrastructure its customers control, industrial backing over American venture money is not an accident.
The sovereignty pitch
Arthur Mensch, Mistral’s co-founder and chief executive, framed the raise around a shift in what customers are asking for. “Organisations want to industrialise AI inside systems that are already complex: their own data, their own tools, their own compliance constraints,” he said. “That’s the real problem.”
Mensch said the funding lets Mistral move faster on research, products, and infrastructure. Kirk Lepke, a partner at EQT and the Scaleup Europe Fund, said most companies at the frontier choose a single layer of the stack. Mistral builds models, infrastructure, and applications together, an approach he called harder but built to give customers more control over their own systems.
Who’s backing the round
The investor list mixes new names with repeat backers. Mistral says it now works with more than 125 enterprises across 20 countries, including Airbus, ASML, and HSBC. For those customers, whose infrastructure a model runs on is a board-level decision rather than a line item.
- New investors joining this round: Advent, funds managed by BlackRock, and the Grand Duchy of Luxembourg.
- Returning investors: NVIDIA, a16z, Bpifrance, BNP Paribas CIB, Salesforce Ventures, General Catalyst, Index Ventures, Lightspeed, Eurazeo, and ASML.
The money funds frontier research and the compute underneath it. Mistral separately raised $830m in debt from seven banks for a data center outside Paris, selling capacity to European industrial groups before construction finished. The company has spent three years arguing that depending on American AI infrastructure is a strategic risk rather than a procurement choice. Its funding round now backs that argument with money. Whether the models justify it is a question the next year will answer.
