Mistral announced a €3 billion, about $3.5 billion Series D on September 8 to expand its data center buildout and computing-capacity business beyond model development. Samsung Electronics led the round, while the Scaleup Europe Fund managed by EQT and existing investor PSG Equity served as co-leads. Chief Executive Arthur Mensch said the money would support Mistral’s own infrastructure and larger models, and Mistral said frontier research would continue alongside the expansion.
What Changed
- Mistral raised €3 billion in a Samsung-led round at a valuation above €21 billion, up from €11.7 billion in September 2025.
- The company is expanding data centers and selling computing capacity while continuing to develop its own AI models.
- Its platform supports third-party models, starting with Z.ai’s GLM-5.2, alongside regional processing options and capacity commitments.
- Mistral expects annual recurring revenue to exceed $1 billion by year-end 2026. That remains a company forecast.

Capital for a broader business
The financing values Mistral at more than €21 billion after the new investment, compared with €11.7 billion when it completed its Series C in September 2025. Mistral described the deal as the largest equity fundraising ever completed by a European technology company.
Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg joined as new investors. Mistral said on September 8 that it operated in 20 countries and supported more than 125 enterprises, including Airbus, ASML and HSBC.
Mistral now plans to own more of the computing capacity its models use. Mensch said in a September 8 interview that the company would build data centers and rent computing capacity to customers. Over five years, he expects the amount of compute Mistral owns to grow “around 100%,” with the long-term goal of relying fully on capacity it builds.
The buildout is already under way
The infrastructure turn predates this round. Mistral announced a €1.2 billion commitment for data centers and computing infrastructure in Sweden in February 2026. The Swedish facility was scheduled to open in 2027. Mistral raised $830 million in debt earlier in 2026 for a data center.
A July 21 agreement made Microsoft a buyer of Mistral’s expanded European computing capacity under a multibillion-dollar commitment. Microsoft did not participate in the Series D, Chief Financial Officer Johan Bergqvist said.
On August 11, Mistral expanded its platform. Customers can select European or U.S. processing regions, reserve capacity with service commitments and deploy third-party models on Mistral’s systems. The company also offers engineering help to integrate AI into customer operations.

Most customers currently run Mistral models in their own data centers or cloud accounts, the company said in August. Its regional service is intended to supplement that capacity when demand rises. Mistral’s disclosure also says limited transfers to subprocessors outside a selected region may occur, so choosing a region does not mean every related operation stays there.
Mistral is using multiyear commitments from companies including Amadeus, ASML and Capgemini to support construction. Its European Compute Units convert those purchase promises into future access to Mistral-built systems.
More models, not only Mistral’s
The first outside model on the platform is GLM-5.2 from Chinese developer Z.ai. Mistral describes it as open weight, meaning customers can obtain and adapt the model’s learned parameters.

Mistral says third-party models can use the same regional controls and service guarantees as its own products. It also says the new funding will expand frontier research and increase the computing capacity used to train its models.
A critic sees a different company
In a published August 17 Journal du Net column, Pierre-Louis Biojout argued that Mistral was moving toward hosting and consulting rather than fulfilling its original promise as a frontier laboratory. He pointed to the addition of GLM-5.2 and hiring for customer-facing engineering roles.
Mensch said Mistral had to keep training its own systems so customers could count on improved models in the future.
Revenue and customers
Mistral expects annual recurring revenue, the annualized value of recurring contracts, to exceed $1 billion by the end of 2026. That is a company forecast, not revenue already earned or a current result independently verified.
Mensch said he expected “to be beating” the target “if everything happens as they are trending,” but declined to provide a new figure. He said Mistral models arriving “very soon” would be “very competitive.”
Frequently Asked Questions
How much did Mistral raise?
Mistral announced a €3 billion Series D, about $3.5 billion, on September 8. The round values it at more than €21 billion after the investment, compared with €11.7 billion in September 2025. Mistral calls it the largest equity fundraising completed by a European technology company.
Who invested in the round?
Samsung Electronics led it, with the Scaleup Europe Fund managed by EQT and existing investor PSG Equity as co-leads. New investors included Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg. Microsoft did not participate, although it agreed in July to buy European computing capacity from Mistral.
What is changing in Mistral’s business?
Mistral is expanding beyond model development into data centers, computing-capacity sales and engineering help for enterprise customers. Its platform also supports third-party models, beginning with GLM-5.2 from Z.ai. The company says the funding will expand frontier research as well as infrastructure.
Does choosing a European processing region keep everything in Europe?
Mistral offers regional processing options, but its disclosure allows limited transfers to subprocessors outside the selected region. Choosing a region therefore does not mean every related operation stays there. Customers also run Mistral models in their own data centers or cloud accounts.
Has Mistral reached $1 billion in annual revenue?
The figure is a forecast for annual recurring revenue by the end of 2026, not revenue already earned. Annual recurring revenue expresses recurring contracts on an annualized basis. Arthur Mensch said he expected to beat the target if current trends continued, but declined to provide a new figure.
