Mistral AI announced on Sept. 8, 2026, that it raised €3 billion in a Series D funding round at a post-money valuation of more than €21 billion, a figure that counts the new money. Samsung Electronics led the round, with co-leads Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity. Mistral builds open-weight AI models, publishing the trained files so anyone can download them and run them on their own computers. The round also brings in a major chip-industry customer: Samsung, which led it, plans to use Mistral's AI in its semiconductor operations.
Mistral said the money will expand its research on the most advanced AI, add computing power for training its models, build infrastructure, and speed up its commercial growth and international reach. The company said it operates across 20 countries and supports more than 125 enterprises, naming Airbus, ASML and HSBC among customers. It described the round as the largest equity fundraising round ever completed by a European technology company, three years after its launch.
Samsung Electronics said on Sept. 9, 2026, that it had entered a strategic partnership with Mistral to use Mistral's AI, including its Mistral Large model, on its own systems across its semiconductor operations, and that it led Mistral's Series D. Samsung said the partnership was announced during a South Korea-France state summit in Paris.
New investors named by Mistral include Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg. Returning backers include a16z, ASML, NVIDIA, Salesforce Ventures and others listed on the company's post. According to a news report, Mistral's Series C a year earlier valued the company at €11.7 billion. Another report said French president Emmanuel Macron framed the Samsung stake as part of a France-South Korea third way in AI.
