Mistral AI Secures €3B Series D, Valuation Over €21B

Mistral announced on September 8, 2026 that it has raised €3 billion in a Series D funding round at a post-money valuation of more than €21 billion, which the company said is the largest equity fundraising round ever completed by a European technology company, three years after its launch.

Samsung Electronics led the round, joined by co-leads Scaleup Europe Fund, which is managed by EQT, and existing investor PSG Equity.

Investors in the Round

Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg joined the round as new investors. Existing investors a16z, ASML, Belfius, BNP Paribas CIB, Bpifrance, Carmignac, DST Global, Eurazeo, General Catalyst, Headline, Hillspire, Index Ventures, Korelya Capital, Lightspeed, NVIDIA, Phoenix Court’s Solar fund (home to LocalGlobe, Latitude and Solar) and Salesforce Ventures also participated.

Mistral said the round reflects a strategic endorsement from investors across Europe, Asia and North America, bringing together a syndicate of strategic and financial investors that includes global technology leaders, growth investors and existing shareholders that have supported its development to date. With a Series C led by ASML and the Series D now led by Samsung Electronics, the company said it has attracted backing from companies at the forefront of advanced manufacturing, engineering and industrial technology, adding that this support reflects growing confidence that its approach can help organizations deploy state-of-the-art AI inside complex real-world environments while maintaining control over their data, infrastructure and knowledge.

Co-lead Scaleup Europe Fund is a European Union initiative structured as a multi-billion late-stage and growth fund targeting strategic technology companies, with artificial intelligence named among its focus areas. According to the European Innovation Council, the fund is anchored by a €1 billion European Commission commitment alongside founding investors including Novo Holdings, EIFO, CriteriaCaixa, Santander/Mouro Capital, Allianz and Wallenberg Investments, and EQT was selected as its fund manager through a competitive public call. The fund was set to make its first investments in autumn 2026.

Stated Use of Proceeds

Mistral said the round will significantly expand its frontier research, which it described as the foundation underpinning its infrastructure, products and sovereignty. The company said the funding will allow it to scale its compute capacity for training powerful models and will help it expand infrastructure and accelerate its commercial growth and international footprint.

The company said it now operates across 20 countries and supports the mission-critical AI transformation of more than 125 global enterprises, naming Airbus, ASML and HSBC among them.

The Company’s Sovereign AI Positioning

In the announcement, Mistral framed the round around a shift it sees in how organizations approach AI. During the first wave of generative AI, the company said, the central question was who could build the most powerful model; organizations and governments are now asking how to harness AI for mission-critical needs without surrendering control over the infrastructure and intelligence loop. The company said demand for that combination of performance with control, choice and independence is growing internationally as enterprises and governments weigh the long-term technology dependencies, data governance requirements and deployment choices that come with any AI investment.

Mistral described itself as the only AI company in the world building what it called the full stack required to answer that question: open-weight models, the infrastructure and compute capacity they run on, and the products that bring them into production, ensuring customers are never locked into a single vendor’s roadmap, pricing or availability. The company said its full-stack and open approach allows organizations to build on it without exposing their most valuable data, workflows and institutional knowledge to anyone outside their own walls.

Mistral said this is what makes its stack the sovereign AI layer, which it defines as retaining control across four dimensions: data that stays inside the organization’s boundaries, models that are controllable and customizable, compute that is private and predictable, and systems in production that are fully controllable and auditable.

Prior Funding and Company Timeline

Mistral’s previous round was a €1.7 billion Series C at an €11.7 billion post-money valuation, announced on September 9, 2025 and led by semiconductor equipment manufacturer ASML, with participation from existing investors DST Global, Andreessen Horowitz, Bpifrance, General Catalyst, Index Ventures, Lightspeed and NVIDIA.

According to the company’s own timeline, Mistral was founded in April 2023, hired its first employee in June 2023 and raised a seed round that same month, followed by a Series A in December 2023 and a Series B in June 2024. The company lists co-founders Arthur Mensch as CEO, Guillaume Lample as Chief Science Officer and Timothée Lacroix as CTO.
