Mistral AI raises €3 billion led by Samsung at over €21 billion valuation

Background

Mistral AI is an AI company that builds large language models and AI products. Like many fast-growing technology companies, it raises money from investors in successive funding rounds. Each round usually brings in new investors and sets a new valuation, the estimated value of the company.

What happened

On 8 September 2026 Mistral AI announced a €3 billion Series D funding round^[2][1]. A Series D is a later funding round that comes after earlier rounds. The round valued the company at more than €21 billion post-money^[1]. A post-money valuation is the company's value after the new investment is counted.

Key details

Samsung Electronics led the round. It was co-led by the Scaleup Europe Fund, which is managed by EQT, and by PSG Equity^[1].

New investors included Advent, BlackRock-managed funds and the Grand Duchy of Luxembourg. Existing investors that took part included a16z, ASML, Bpifrance, General Catalyst, Lightspeed, NVIDIA and Salesforce Ventures^[1].

Mistral called the round the largest equity round ever completed by a European technology company^[1]. An equity round means investors receive shares in the company in exchange for their money, as opposed to a loan.

Customers and reach

Mistral said it operates in 20 countries and has more than 125 enterprise customers. Those customers include Airbus, ASML and HSBC^[1]. Enterprise customers are businesses that buy AI products for their own operations, rather than individuals using a chat app.

Impact

The round brings together a wide group of investors. It includes chip-industry investors such as NVIDIA and ASML, other investors, and the Grand Duchy of Luxembourg. That mix shows both financial and industrial support for Mistral's business.

The announcement gives the amount, the valuation, the leading investors and the customer count. It does not give details of how the money will be spent, so those plans should be checked against later statements from Mistral.
