Mistral raises €3 billion to build an end-to-end European AI

Mistral raises 3 billion euros from Samsung, the Scaleup Europe fund, and its historical investors, at a valuation exceeding 21 billion.

Three years after its founding, Mistral has raised €3 billion. The Series D round values the French company at more than €21 billion after the investment. According to Mistral, this is the largest equity funding round ever completed by a European technology company.

Samsung Electronics led the round alongside the EQT-managed Scaleup Europe Fund and existing investor PSG Equity. Advent, funds managed by BlackRock, and the Grand Duchy of Luxembourg also joined as new shareholders.

Most of Mistral’s existing investors participated again. The list includes a16z, ASML, Belfius, BNP Paribas CIB, Bpifrance, Carmignac, DST Global, Eurazeo, General Catalyst, Headline, Hillspire, Index Ventures, Korelya Capital, Lightspeed, Nvidia, Salesforce Ventures, and Phoenix Court’s Solar fund. The distribution of the €3 billion among these investors has not been disclosed.

The amount marks another major acceleration for Mistral. In September 2025, the company raised €1.7 billion in a Series C led by ASML, at a valuation of €11.7 billion. Its theoretical value has therefore increased by nearly 80% in one year. Including every round announced since its launch, the company has now raised approximately €5.7 billion in equity financing.

A post-money valuation includes the capital injected during the round. It does not represent Mistral’s revenue or a sum immediately available to its shareholders. It reflects the price investors agreed to assign to the company after the latest investment.

Mistral plans to use the funds to increase its computing capacity, train new models, develop its infrastructure, and accelerate commercial expansion. The company also intends to strengthen its international presence. It says it now operates in 20 countries and supports more than 125 large organizations, including Airbus, ASML, and HSBC.

The company is no longer focused solely on releasing models that compete with systems developed by American and Chinese labs. It is gradually building an offering that covers training, hosting, adaptation to corporate data, and the deployment of production services. Infrastructure now occupies the same strategic position as model research.

Mistral presents this integrated structure as an answer to the demand for “sovereign AI.” An organization should be able to choose where its data is stored, which machines run its models, who can modify them, and how their decisions are monitored. It would no longer depend entirely on a single provider’s commercial policies, pricing, or technical roadmap.

This sovereignty does not mean that every component is designed and manufactured in Europe. Mistral still relies on chip suppliers, energy providers, data centers, and international financial partners. Samsung, Nvidia, BlackRock, Advent, a16z, and Salesforce Ventures are all headquartered outside Europe.

The term refers more broadly to the ability to retain control. Customers can run certain models in their own environments, keep sensitive information within infrastructure of their choosing, and adapt systems to internal procedures. Mistral also says its founders and employees retain more than half of the voting rights, while most of its capital remains European.

Samsung’s arrival nevertheless carries industrial significance. After ASML led the previous round, Mistral has secured the backing of another company that plays a central role in electronic components and manufacturing. Samsung produces memory chips, processors, devices, and equipment for data centers. The announcement, however, provides no details about any commercial or technical agreement connected to the investment.

The Scaleup Europe Fund adds another dimension. Created with support from the European Commission, it targets European technology companies that have reached a stage where their financing needs often exceed the capacity of the continent’s traditional venture capital funds. The Commission has committed €1 billion to a vehicle seeking to raise €5 billion.

EQT manages the fund independently and on commercial terms. Public institutions and other limited partners participate in its governance but are not expected to select individual investments directly. Target investments generally reach €100 million or more. The Mistral deal could rank among its first major transactions.

The initiative addresses a long-standing weakness in European technology financing. Startups can often raise their first few million euros on the continent, then turn to American or Asian investors when they need to fund infrastructure, international expansion, or several years of research. AI intensifies this imbalance because of the cost of accelerators, electricity, and data centers.

Mistral presents its open-weight models as another point of differentiation. The weights of certain systems can be downloaded, hosted, and adapted by users. This approach reduces dependence on a remote API and makes deployment easier in regulated or isolated environments.

An open-weight model is not necessarily fully open source. Training data, preparation tools, and the complete training process may remain confidential. Mistral also sells proprietary models and services. Its strategy therefore combines open releases with a paid platform and enterprise-only products.

The new funding is intended to support both sides of that strategy. Research remains essential if Mistral wants its models to compete with the strongest systems available. Infrastructure must make those models usable with the availability, confidentiality, customization, and monitoring guarantees expected by large organizations.

Mistral has expanded its enterprise product line. Le Chat Enterprise targets internal corporate use. Mistral Compute provides European computing infrastructure. Forge is designed to build specialized models around an organization’s knowledge. Workflows coordinates agents that complete several steps and use tools authorized by their employer.

This broader offering has raised questions about the company’s direction.
