Mistral raises €3B at a €21B valuation in Europe’s largest tech round

Mistral said on Tuesday it has raised 3 billion euros in a Series D round at a post-money valuation of more than 21 billion euros. The company calls it the largest equity fundraising round ever completed by a European technology company, three years after its launch. Samsung Electronics led it.

Co-leading were the Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity. Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg came in as new investors. Existing backers including a16z, ASML, Bpifrance, NVIDIA, Lightspeed and Salesforce Ventures also participated. CNBC puts the round at $3.5 billion and the valuation at $24 billion.

The second number is the one that moved. CNBC reports Mistral was valued at 11.7 billion euros a year ago, after a round led by the Dutch chip equipment maker ASML. That’s a rise of roughly 79% in twelve months, by our arithmetic. Which means the round repriced the company faster than it raised money for it.

CEO Arthur Mensch told CNBC the money goes into infrastructure, including Mistral’s own data centres, and into renting out computing capacity. He also said the company would train bigger and faster models. That’s a capital plan, not a product plan, and it explains why the raise is this size.

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.

But the revenue side is thinner. Mensch said earlier this year he expected annual recurring revenue to exceed $1 billion this year, and told CNBC he now expects “to be beating” that figure if things keep trending as they are. He declined to give a revised number. Against CNBC’s $24 billion, that’s roughly 24 times a revenue figure the company hasn’t restated, which is the kind of gap a private valuation is designed to absorb.

The co-lead is the part worth watching. The Scaleup Europe Fund is the EU-backed vehicle EQT was picked to manage in May 2026, with a target size of 5 billion euros, under the EU Startup and Scaleup Strategy. Its founding investors alongside the European Commission include Novo Holdings, Santander’s Mouro Capital, Allianz and Wallenberg Investments, according to the Commission’s own page. Its first investment, in August, co-led a 1 billion euro round in the Finnish satellite firm ICEYE.

European public money is now a co-lead in Europe’s largest tech equity round, just weeks after its own first deal.

Mistral’s pitch rests on being neither American nor Chinese, and on shipping open weights rather than a closed API. That’s a real differentiator in Europe, though it isn’t a moat, because open weights are a distribution choice other labs can copy. Mensch’s counter is dependency risk: he told CNBC it’s hard for European companies to rely on long-term support for Chinese models, given uncertainty over upgrades and possible export restrictions.

“At this point in time, we are seeing that the volatility in this space is actually quite extreme,” Mensch said. He framed continued in-house training as the only way to guarantee customers better models a year out. Tech.eu notes Mistral was founded in 2023 and sells to businesses and public-sector bodies.

So there are two things to watch. Mensch said the models Mistral releases “very soon” would be “very competitive”, so that’s a claim with a near-term test attached. The other is whether owned compute actually doubles, because the whole sovereignty argument rests on it.
