Mistral secured a funding round of three billion euros on September 8, 2026, led by the South Korean electronics company Samsung. The valuation of the French AI provider jumps to more than 21 billion euros – almost double what it was a year ago. This is the largest equity round ever raised by a European technology company.
Samsung leads the circle of investors with new backers
According to Mistral’s own announcement, the Series D round is led by Samsung Electronics together with the EU-affiliated Scaleup Europe Fund, managed by the investment company EQT, as well as existing investor PSG Equity. New to the circle of investors are the financial investor Advent, funds managed by BlackRock, and the Grand Duchy of Luxembourg. Among the previous backers, chip manufacturer ASML, venture capital firm a16z, General Catalyst, Index Ventures, Nvidia, and Salesforce Ventures remain involved.
The new valuation of over 21 billion euros is almost double the 11.7 billion euros of the Series C a year ago, which was also led by ASML. Mistral itself describes the round as the largest equity financing of a European technology company – an assessment that is also independently shared by CNBC and other business media.
Capital flows into own data centers instead of rented cloud
According to company information, the fresh capital is primarily flowing into the expansion of its own data centers rather than into rented cloud capacity from third-party providers. CEO Arthur Mensch announced to CNBC that the self-operated computing power is expected to grow by around 100 percent over the next five years, while simultaneously training larger and faster models.
The course continues a strategy that Mistral has already pursued with the nearly four billion euro infrastructure project Mistral Compute: A data center near Paris is already in operation with around 13,800 Nvidia graphics processors of the GB300 type, and a second location in Sweden is being developed together with the operator EcoDataCenter. By the end of 2027, Mistral aims for 200 megawatts of computing capacity across Europe, and for the time thereafter, a roughly 1.4-gigawatt campus in France is planned together with the sovereign wealth fund MGX from the United Arab Emirates and Nvidia. Already in July, Microsoft expanded its partnership with Mistral with a multi-billion infrastructure agreement, but was not involved as an investor in the current round.
Customer numbers and revenue targets grow with valuation
Mistral now estimates its customer base at more than 125 companies in 20 countries, including aircraft manufacturer Airbus, chip supplier ASML, and bank HSBC. CEO Arthur Mensch estimated the expected annual revenue at over one billion dollars before the end of 2026 – a figure that is not independently verified. According to him, having control over AI systems and being able to adapt them to one’s own needs is as important as their pure performance; this justifies the focus on open model weights alongside its own infrastructure. Customers want to industrialize AI in already complex systems, with their own data, their own tools, and their own compliance requirements.
The positioning as a European, sovereign alternative to US providers like OpenAI and Anthropic, as well as to Chinese models, runs through from the product to the capital structure of the new round: For the first time, publicly supported European investors are also at the table with the EU-affiliated Scaleup Europe Fund and the Grand Duchy of Luxembourg.
It remains to be seen whether Mistral can maintain the self-imposed pace of infrastructure expansion: The planned 1.4-gigawatt campus in France is not expected to be completed until after 2030, while competitors like OpenAI and Anthropic already have a multiple of computing power today. It will also be crucial whether the new European backers will follow suit in future rounds or whether Mistral will again have to rely on non-European capital, such as that from the UAE funds MGX, for the next capacity leap.
