Mistral AI SAS is a French artificial intelligence company headquartered in Paris, founded in 2023 by three French AI researchers. It develops large language models (LLMs) and has become the highest-valued European AI company. In June 2024, the company secured a €600 million ($645 million) funding round, increasing its valuation to €5.8 billion ($6.2 billion), a key event in the European AI landscape.
The June 2024 funding round, often referred to as Mistral's Series A or Series B depending on the source, was led by existing investors and attracted new backers, reflecting the growing investor interest in European AI startups amid the global AI boom. The round valued the company at approximately $5.2 billion, more than doubling its previous valuation from December 2023. This funding positioned Mistral as the fourth-largest AI company globally by valuation, and the first outside the San Francisco Bay Area.
Background and Founding
Mistral AI was established in April 2023 by Arthur Mensch, Guillaume Lample, and Timothée Lacroix, all former researchers at major AI labs. Mensch had worked at Google DeepMind, while Lample and Lacroix had been at Meta Platforms. The trio met during their studies at École polytechnique. The company is named after the mistral, a powerful wind in southern France.
Early Funding Rounds
In June 2023, Mistral raised €105 million ($117 million) in a seed round from investors including Lightspeed Venture Partners, Eric Schmidt, Xavier Niel, and JCDecaux, valuing the company at around €240 million. On 10 December 2023, the company announced a €385 million ($428 million) round led by Andreessen Horowitz, with participation from BNP Paribas and Salesforce, valuing Mistral at over €2 billion. This round was sometimes referred to as a Series A, but the June 2024 round was more commonly labeled as a Series B.
The June 2024 Funding Round
On 16 April 2024, reports emerged that Mistral was in talks to raise €500 million, which would more than double its valuation to at least €5 billion. By June 2024, the company confirmed a €600 million ($645 million) round, bringing its valuation to €5.8 billion ($6.2 billion). This round was led by existing investors and included participation from new backers, though specific names were not fully disclosed at the time. The funding was intended to accelerate Mistral's model development, expand its team, and enhance its cloud infrastructure.
Strategic Partnerships and Investments
In February 2024, Microsoft announced a $16 million investment in Mistral AI, alongside a partnership to make Mistral's models available on Microsoft's Azure platform. This deal was part of a broader trend of tech giants investing in AI startups. In June 2024, Mistral also announced a partnership with NVIDIA to optimize its models for NVIDIA's hardware, though the details of this collaboration were not fully detailed at the time.
Impact on European AI
The June 2024 funding round solidified Mistral's position as a leading European AI company, often cited as a counterweight to American dominance in the field. The company's success was seen as a boost for European AI efforts, aligning with the European Union's push for digital sovereignty. Mistral's models, including the Mistral 7B and Mixtral 8x7B, gained attention for their performance and open-source availability.
Subsequent Developments
Following the June 2024 round, Mistral continued to grow. In April 2025, it announced a €100 million partnership with CMA CGM. In August 2025, reports indicated talks for a $1 billion round at a $10 billion valuation, and in September 2025, the company secured a €2 billion investment valuing it at €12 billion, with ASML investing $1.5 billion for an 11% stake. By September 2026, Mistral's valuation reached €21 billion after Samsung Electronics acquired a stake.
Models and Services
Mistral has released several notable models, including Mistral Large and Codestral. In November 2024, it updated its chatbot Le Chat with image generation capabilities using Black Forest Labs' Flux Pro. In February 2025, Le Chat was released on mobile, and a Pro tier was introduced. In 2026, Le Chat was rebranded as Mistral Vibe.
Conclusion
The June 2024 funding round was a pivotal moment for Mistral AI, providing the capital needed to scale its operations and compete globally. It underscored the growing investor confidence in European AI startups and set the stage for Mistral's subsequent expansion and partnerships.
