Mistral might not be anywhere close to the frontier in AI, but it’s still doing pretty well for itself.
Mistral has closed a €3 billion (about $3.48 billion) Series D round, taking its post-money valuation past €21 billion (roughly $24 billion). The company says it’s the largest equity fundraise ever completed by a European technology company, arriving just three years after Mistral’s launch.
Samsung Electronics led the round. Scaleup Europe Fund, managed by EQT, and existing backer PSG Equity came in as co-leads. The round also drew continued participation from ASML, Nvidia, and BNP Paribas CIB, among others, alongside a mix of new investors that includes Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg. Existing shareholders a16z, Belfius, Bpifrance, Carmignac, DST Global, Eurazeo, General Catalyst, Headline, Hillspire, Index Ventures, Korelya Capital, Lightspeed, and Salesforce Ventures also returned for the round.
The jump is a sharp one even by the standards of a company that has repeatedly reset the bar for European AI funding. Mistral was valued at €5.8 billion at its Series B in June 2024, before ASML led a €1.7 billion Series C last September that pushed the valuation to €11.7 billion. The new round nearly doubles that figure again in under a year, and cements Mistral’s spot atop lists of Europe’s most valuable AI startups.
Mistral says the fresh capital will go toward scaling compute for training its models, expanding its infrastructure footprint, and accelerating commercial growth internationally. The company now operates in 20 countries and counts more than 125 global enterprises, including Airbus, ASML, and HSBC, among its customers for what it calls mission-critical AI deployments.
In its announcement, Mistral framed the round around a shift in what enterprises and governments are actually asking for from AI vendors. Where the first wave of the industry was consumed by a race to build the single most capable model, the company argues the more pressing question now is how organizations can put AI to work without handing over control of their infrastructure and their data. Mistral positions itself as the only AI company building the complete stack needed to answer that: open-weight models, the compute and infrastructure they run on, and the products that put them into production, all without locking customers into one vendor’s pricing or roadmap.
That pitch centers on what Mistral calls “sovereign AI” — control across four fronts: data that never leaves an organization’s own boundaries, models that can be customized and controlled, private and predictable compute, and production systems that remain auditable. It’s a framing aimed squarely at the governments and regulated industries increasingly wary of depending on a single foreign AI provider.
The Samsung-led round also extends a pattern of industrial giants backing Mistral directly. ASML led the Series C in 2025 and remains a major shareholder; Samsung now takes the lead role in the Series D. Mistral has separately raised $830 million in debt financing this year to fund a new data center near Paris as part of its “Mistral Compute” buildout, which the company has said it wants to scale toward a gigawatt of capacity by the end of the decade.
Mistral has now raised well over $6 billion in total across its funding history, a run that began with a €105 million seed round in June 2023 and has accelerated with each subsequent raise. With Samsung, BlackRock, and Luxembourg’s sovereign backing now added to a roster that already included ASML and Nvidia, the round reinforces Mistral’s position as the clearest European counterweight to the US and Chinese AI labs it competes with.
