- Mistral raised 3 billion euros in a Series D led by Samsung Electronics, at a post-money valuation above 21 billion euros.
- The valuation nearly doubles the roughly 11.7 billion euros Mistral reached a year ago, and is the largest equity round ever raised by a European technology company.
- Nvidia, ASML and Salesforce Ventures joined, backing Mistral's plan to own the full stack of open-weight models, infrastructure and compute.
Samsung leads a 3 billion euro round that values Mistral above 21 billion
Paris-based Mistral AI said on September 8 that it had closed 3 billion euros in Series D funding at a post-money valuation of more than 21 billion euros. Samsung Electronics led the round, with co-leads Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity. Nvidia, ASML, a16z, General Catalyst, Lightspeed, BlackRock-managed funds and Salesforce Ventures also took part.
The raise is the largest equity financing ever completed by a European technology company, arriving three years after Mistral launched. It roughly doubles the near 11.7 billion euro valuation the company reached in its September 2025 round led by chip-equipment maker ASML, according to reporting by Bloomberg. Mistral said the capital will scale its compute capacity for training, expand infrastructure and accelerate commercial growth.
The company framed the round around a single idea, that control of the stack is what makes AI sovereign.
Mistral is the only AI company in the world building the full stack required: open-weight models, the infrastructure and the compute capacity they run on. That is what makes Mistral's stack the sovereign AI layer, retaining control across data, models, compute and systems in production.Mistral AI, Series D announcement, September 8, 2026
Why Samsung's lead matters more than the headline number
The identity of the lead investor is the signal. Samsung Electronics is a manufacturer, not a fund, and its money arrives with supply-chain and hardware reach that a purely financial backer cannot offer. With ASML and Nvidia also on the cap table, Mistral now counts three of the most consequential names in AI hardware among its owners, a base of support aimed squarely at the compute bottleneck that constrains every frontier lab.
That positioning separates Mistral from its larger American rivals. Where OpenAI and Anthropic rent capacity through multi-billion-dollar cloud commitments, Mistral is pitching European governments and enterprises a stack they can run and audit themselves, an argument that also underpins the wave of sovereign compute deals now spreading across the Gulf and the push for fully open model weights. The 21 billion euro valuation is still a fraction of OpenAI's, yet it makes Mistral the clear anchor of Europe's effort to keep a frontier lab of its own.

| Post-money valuation | More than 21 billion euros, up from about 11.7 billion in September 2025 |
| Lead investor | Samsung Electronics, with co-leads EQT's Scaleup Europe Fund and PSG Equity |
| Strategic backers | Nvidia, ASML, Salesforce Ventures, a16z, General Catalyst, Lightspeed, BlackRock-managed funds |
| Milestone | Largest equity fundraising ever by a European technology company |
Europe has spent two years worried it would become a customer of American and Chinese AI rather than a producer of it. A 3 billion euro round, led by an Asian manufacturer and backed by the continent's most valuable chip supplier, does not settle that question. It does buy Mistral the compute, and the time, to keep answering it on its own terms.
