Mistral raises €3 billion at a valuation above €21 billion

Mistral AI has raised €3 billion in a Series D funding round that values the company at more than €21 billion once the new investment is counted. Mistral says this is the largest equity fundraising round ever completed by a European technology company. Samsung Electronics led the round. It comes three years after the company was founded.

Scaleup Europe Fund, managed by the investment firm EQT, and PSG Equity, already a shareholder, co-led alongside Samsung. Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg came in as new investors. Existing backers that added money include a16z, ASML, Bpifrance, DST Global, General Catalyst, Index Ventures, Lightspeed, NVIDIA and Salesforce Ventures. Mistral’s earlier Series C was led by ASML.

Mistral says the money will expand its frontier research, meaning the training of its most capable models, and pay for more computing capacity to run that training. The company also plans to build more infrastructure and sell in more countries. It now operates across 20 countries and says it supports over 125 large enterprise customers, among them Airbus, ASML and HSBC.

The company builds its case around what it calls sovereign AI: systems a business or government can run without giving an outside supplier control of its data, models and computing. Mistral says it is the only AI company building the full stack for this, which it lists as open-weight models, meaning models whose trained parameters are publicly downloadable, plus the infrastructure and compute they run on and the products built on them. It says this stops customers being tied to one vendor’s roadmap, pricing or availability. Those are Mistral’s descriptions of its own position, and the announcement carries no outside assessment of them.

What the round does not say

Mistral did not give a timeline for spending the €3 billion or say how much compute it intends to add. It did not publish revenue, a staff target or specific model-release plans with the raise. The company said the investor group spans Europe, Asia and North America, and noted that its Series C was led by ASML and its Series D by Samsung, both firms in manufacturing and industrial technology.

What to watch is where the money goes. Concrete markers include any new data-centre or chip-supply agreements, the release of a next flagship open-weight model, and whether the customer count Mistral reports climbs above 125 in later updates. Samsung’s place as lead investor also leaves open whether the two will announce product ties, which neither has described so far.
