# Mistral AI's Series B (2024)

Mistral AI, a French artificial intelligence company, raised €640 million in a Series B round in June 2024, valuing the company at €5.8 billion. This funding round positioned Mistral as a leading European AI firm.

Mistral AI, a French artificial intelligence company headquartered in Paris, completed a Series B funding round in June 2024, raising €600 million (approximately $645 million) and achieving a valuation of €5.8 billion (about $6.2 billion). This round marked a significant milestone for the company, which had been founded only a year earlier, and solidified its position as the highest-valued AI startup in Europe and the fourth-largest globally in the AI industry at that time, ranking first outside the San Francisco Bay Area.

The Series B round was led by existing investors and attracted new backers, reflecting growing confidence in Mistral's technology and its role in the European AI ecosystem. The funding was intended to accelerate the development of large language models, expand computing infrastructure, and support the company's expansion into enterprise and public-sector markets.

## Background and Founding

Mistral AI was established in April 2023 by three French AI researchers: Arthur Mensch, Guillaume Lample, and Timothée Lacroix. Mensch, who had previously worked at [Google DeepMind](https://www.wikiprompt.org/wiki/google-deepmind), brought expertise in advanced AI systems, while Lample and Lacroix, both specialists in large-scale AI models, had worked at Meta Platforms. The trio met during their studies at École Polytechnique, a prestigious French engineering school.

The company's name derives from the mistral, a powerful, cold wind in southern France, originating from the Occitan language. This name reflects the founders' ambition to create a force in AI that would be distinctly European.

## Early Funding Rounds

Before the Series B, Mistral had already attracted substantial investment. In June 2023, the startup raised €105 million ($117 million) in a seed round with investors including Lightspeed Venture Partners, Eric Schmidt, Xavier Niel, and JCDecaux. At that time, the valuation was estimated at €240 million ($267 million) by the Financial Times.

On 10 December 2023, Mistral announced a second fundraising of €385 million ($428 million), led by Andreessen Horowitz, with participation from BNP Paribas and Salesforce. This round valued the company at over €2 billion. In February 2024, Microsoft invested $16 million in Mistral, further cementing its ties with major tech players.

## The Series B Round

In 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 secured €600 million ($645 million) in a Series B round, increasing its valuation to €5.8 billion ($6.2 billion). This round was notable for its size and the participation of both European and international investors, underscoring the strategic importance of Mistral in the global AI landscape.

The Series B funding was intended to support the scaling of Mistral's operations, including the development of new models, expansion of its cloud infrastructure, and hiring of top talent. It also positioned the company to compete more aggressively with US-based AI giants like [OpenAI](https://www.wikiprompt.org/wiki/openai) and [Anthropic](https://www.wikiprompt.org/wiki/anthropic).

## Post-Series B Growth

Following the Series B, Mistral continued to grow rapidly. In April 2025, the company announced a €100 million partnership with CMA CGM, a major shipping company. In August 2025, the Financial Times reported that Mistral was in talks to raise $1 billion at a $10 billion valuation. By September 2025, Bloomberg confirmed that Mistral had secured a €2 billion investment, valuing it at €12 billion ($14 billion). This round included a $1.5 billion investment from ASML, the Dutch semiconductor equipment maker, which acquired an 11% stake in the company.

In February 2026, Mistral announced a strategic partnership with Accenture to deploy enterprise AI at scale, though financial terms were not disclosed. In March 2026, the company raised $830 million to build new datacenters near Paris and in Sweden, and also announced a partnership with NVIDIA to accelerate the development of open frontier AI models.

In July 2026, Mistral expanded its partnership with Microsoft through a multibillion-dollar agreement supporting AI infrastructure in Europe. Microsoft agreed to use part of Mistral's expanded European computing capacity, and the companies added Mistral Medium 3.5 and OCR 4 models to Microsoft Foundry, with Medium 3.5 also available in Copilot Studio.

In September 2026, Samsung Electronics acquired a stake in Mistral in a €3 billion transaction, raising Mistral's valuation to €21 billion. As of 2025, the company's valuation had already exceeded $14 billion, making it the highest-valued European AI company.

## Services and Products

Mistral's primary product is Le Chat, a chatbot launched in February 2024. On 19 November 2024, the company announced updates to Le Chat, adding image generation capabilities using Black Forest Labs' Flux Pro model. On 6 February 2025, Mistral released Le Chat on iOS and Android, and introduced a Pro subscription tier priced at $14.99 per month, offering access to more advanced models, unlimited messaging, and web browsing. At the end of May 2026, Le Chat was renamed Vibe, with new features introduced simultaneously.

## Model Development

Mistral has released a series of large language models, each with distinct capabilities. The Mistral 7B model, released in 2023, was claimed to outperform LLaMA 2 13B on all benchmarks and match LLaMA 34B on many, despite having only 7 billion parameters. The Mixtral 8x7B, a mixture-of-experts model, was claimed to beat LLaMA 70B and GPT-3.5 in most benchmarks. In March 2024, research by Patronus AI found that Mixtral generated copyrighted text verbatim in 22% of responses, compared to 44% for GPT-4, 10% for LLaMA-2, and 8% for Claude 2.

Subsequent releases included Mistral Small 3.1 (17 March 2025), Mistral Medium 3 (7 May 2025), and the Magistral Small and Medium reasoning models (10 June 2025), which introduced chain-of-thought capabilities. On 2 December 2025, Mistral released Mistral Large 3, a sparse mixture-of-experts model with 41 billion active parameters and 675 billion total parameters, along with Ministral 3, three small dense models with 3, 7, and 14 billion parameters. Devstral 2 and Devstral Small 2 followed on 10 December 2025, with Devstral Small 2 having 24 billion parameters.

## Political Significance

Mistral is a primary beneficiary of the European Union's push towards digital sovereignty, responding to the AI boom and the AI arms race between the US and China. In May 2026, CEO Arthur Mensch addressed France's National Assembly, arguing against France becoming a US "vassal state" and cautioning against the use of foreign AI in the French Armed Forces. This political engagement highlights Mistral's role as a strategic asset for Europe's technological independence.

## Acquisitions and Partnerships

In February 2026, Mistral acquired Koyeb, a Paris-based AI startup. On 19 May 2026, it announced the acquisition of Emmi AI, an Austrian company developing AI simulation models for industrial engineering. These acquisitions, along with partnerships with companies like [NVIDIA](https://www.wikiprompt.org/wiki/nvidia), [Microsoft](https://www.wikiprompt.org/wiki/microsoft), and [Samsung Electronics](https://www.wikiprompt.org/wiki/samsung-electronics), have expanded Mistral's capabilities and market reach.

## Conclusion

The Series B round in June 2024 was a pivotal moment for Mistral AI, providing the capital and validation needed to scale its operations and compete on a global stage. Since then, the company has grown into a major player in the AI industry, with a valuation exceeding €21 billion as of September 2026, and continues to play a central role in Europe's AI strategy.
