Mistral Raises €3 Billion in Europe's Largest Tech Funding Round, Led by Samsung

Mistral AI, the three-year-old Paris company that has positioned itself as Europe's answer to OpenAI and Anthropic, said Monday it has raised €3 billion in a Series D funding round led by Samsung Electronics, a deal that values the company at more than €21 billion and that Mistral called the largest equity fundraising ever completed by a European technology company.

The round was announced from the Élysée Palace in Paris, where it formed part of a state visit by South Korean President Lee Jae-myung, underscoring how thoroughly the deal has become entangled with government-level industrial policy on both sides. Samsung and Mistral simultaneously announced a separate strategic partnership under which Samsung will build customized, on-premises AI models — using Mistral's technology, including its flagship Mistral Large model — across its semiconductor fabrication operations, according to a joint announcement published on Samsung's Global Newsroom.

The numbers

The €3 billion raised (about $3.5 billion) pushes Mistral's post-money valuation past €21 billion, according to Mistral's own announcement, roughly double the €11.7 billion valuation it commanded a year ago when ASML led its €1.7 billion Series C. Samsung led the new round, with the EU-backed Scaleup Europe Fund, managed by the private equity firm EQT, and existing investor PSG Equity serving as co-leads. New backers include Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg, while a roster of existing investors — a16z, ASML, General Catalyst, Lightspeed, Nvidia, Salesforce Ventures and several French institutions including Bpifrance and BNP Paribas CIB — added to their stakes, according to TechCrunch's reporting on the round.

Mistral says its annualized revenue run rate has climbed past $400 million, up from roughly $20 million a year earlier, and Mensch has said the company is projecting it will pass $1 billion in annual recurring revenue by the end of 2026. The company has separately committed some €4 billion to data centers in France and Sweden, including an $830 million debt facility raised earlier this year to build a Nvidia-powered cluster near Paris.

How Mistral got here

Mistral was founded in April 2023 by Arthur Mensch and two colleagues who had worked on large language models at Google DeepMind and Meta, and it built its early reputation releasing openly licensed models as a counterweight to the closed systems sold by OpenAI, Google and Anthropic. That open-weight strategy, paired with a pitch to European governments and regulated industries that they could run AI without routing sensitive data through American cloud providers, has since hardened into a business plan built around the idea of "sovereign AI" — infrastructure and models kept under domestic or regional control.

The company's valuation has risen in roughly annual jumps: it was valued near €5.8 billion at the end of 2024, then €11.7 billion after the ASML-led Series C in September 2025, and now more than €21 billion. Chip and equipment makers have been recurring backers throughout — ASML first, and now Samsung, which supplies both memory chips and foundry services to much of the AI industry.

Who is affected

Mistral says it now serves more than 125 enterprise customers across 20 countries, including Airbus, ASML and HSBC, and roughly 60 percent of its revenue currently comes from European customers. The Samsung partnership extends that customer base into semiconductor manufacturing itself: Samsung's Device Solutions division plans to apply Mistral's models to defect detection and process optimization on its chip production lines, work it says will stay on Samsung's own infrastructure rather than being sent to outside servers.

The deal also affects the pool of investors betting on a distinct European AI champion. Nvidia and ASML, both of which sell the equipment and chips that AI labs depend on, are increasing their exposure to a company that competes with the American labs that are also their biggest customers. And the involvement of the EU-backed Scaleup Europe Fund and the Luxembourg government ties part of the round directly to European public money aimed at keeping frontier AI development on the continent.

What people are saying

"AI is reshaping how we build complex technologies, from silicon to software. We are proud to support Samsung Electronics with our expertise in electronics and semiconductors, helping to improve how chips are designed and manufactured, and to accelerate technical progress across the global semiconductor and AI value chain."

That was Mensch, Mistral's co-founder and chief executive, quoted in the companies' joint statement. Young Hyun Jun, vice chairman and chief executive of Samsung's Device Solutions division, said in the same release that "increasing complexities involved in AI chip design and manufacturing requires continuous innovation in semiconductor technologies," and that Samsung was looking to Mistral to help "deliver new breakthroughs across the semiconductor ecosystem essential to the AI era."

Mensch has also framed the raise as a bet on owning infrastructure rather than renting it. "Long term, the plan is to fully rely on capacity that we are building ourselves," he told CNBC in comments carried by Yahoo Finance, adding that the compute Mistral owns outright is set to roughly double every year for the next five years. French President Emmanuel Macron, hosting the announcement alongside South Korea's Lee Jae-myung, called the timing of the deal significant, telling reporters at the state visit's joint appearance that the agreement just signed between Samsung and Mistral AI was "of the utmost importance" to deepening industrial cooperation between France and South Korea on semiconductors, artificial intelligence and quantum computing.

What happens next

Mistral says the new capital will go toward frontier research, expanding its own data-center footprint, and international commercial growth, on top of the money already committed to French and Swedish facilities. The Samsung partnership is still in its early stages: the companies have not set a timeline for when Mistral-powered tools will be deployed across Samsung's fabs, and financial terms of Samsung's specific stake were not disclosed. Mistral's next test will be whether it can convert a round this large into the revenue growth needed to justify the valuation. Even at €21 billion, Mistral remains valued well below OpenAI and Anthropic, and enterprise AI adoption across the European Union still lags the United States, sitting at roughly 13.5 percent by one recent estimate. The European Commission has separately pledged some €200 billion toward AI investment continent-wide, including plans for a network of AI "gigafactories" — the broader policy backdrop Mistral is now betting its expansion against.
