Mistral AI has closed a EUR3 billion Series D funding round — its fourth major round of venture funding — that values the French artificial-intelligence company at more than EUR21 billion, the company announced Sept. 8, 2026. Samsung Electronics led the round, with Scaleup Europe Fund, managed by EQT, and existing backer PSG Equity serving as co-leads.
The raise comes almost exactly a year after Mistral’s previous round: a EUR1.7 billion Series C in September 2025, led by chipmaking-equipment giant ASML, that valued the company at EUR11.7 billion. In roughly twelve months, Mistral raised roughly 76% more money in this round than in the last one, while its valuation climbed to nearly double what it was then.

A long list of existing investors also returned:

Mistral and multiple outlets are describing this as the largest equity fundraising round any European technology company has ever completed — a characterization that traces back to Mistral’s own announcement and has been repeated by outlets including tech.eu, EU-Startups and Dataconomy. Nothing in the reporting available compares the round directly, dollar for dollar, against the next-largest European tech raise on record.
What the money is for
CEO Arthur Mensch told CNBC the funding will go toward building and owning data centers, plus — in the meantime, while that owned capacity is being built out — renting additional computing capacity. He framed the long-term goal as self-reliance: “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.” In plain terms, Mensch is projecting that the compute Mistral owns outright will roughly double over the next five years, even as the company keeps renting extra capacity along the way.
Mistral says it now operates in 20 countries and supports more than 125 enterprise customers, naming Airbus, ASML and HSBC among them.
Profit, revenue and an IPO — what’s confirmed and what isn’t
Here’s what Mistral has confirmed, and what remains a projection or an outside estimate:
- Profitability: not disclosed by Mistral.
- 2026 revenue target: Mensch told CNBC the company projects passing EUR1 billion in annual recurring revenue by the end of 2026 — a projection, not a disclosed current figure.
- Third-party revenue estimate: separate from this announcement, some third-party analysts put Mistral’s annualized recurring revenue at roughly $400 million as of around January 2026, up from about $20 million at the end of 2024 — an estimate Mistral itself has not confirmed.
- IPO: Mensch has said in interviews separate from this announcement that Mistral isn’t planning to pursue an IPO anytime soon, while still calling an eventual public listing the “natural path” for an independent company long-term.
