Mistral Raises Record $3.5 Billion in Samsung-Led Round, Valuation Nearly Doubles to €21 Billion

Mistral AI announced Tuesday that it has secured €3 billion ($3.5 billion) in a Series D funding round led by Samsung Electronics, propelling the French artificial intelligence startup's post-money valuation to more than €21 billion. The company said this marks the largest equity fundraising round ever completed by a European technology firm, underscoring the region's growing ambitions in the global AI race.

The round was led by Samsung, with co-leads Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity. New participants included Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg. Existing backers such as a16z, ASML, General Catalyst, Lightspeed, NVIDIA, and Salesforce Ventures also joined the round, reflecting broad confidence in Mistral's trajectory.

CEO Arthur Mensch told CNBC that the fresh capital will be channeled into building and owning data centers while also renting additional computing capacity to meet surging demand. "Long term, the plan is to fully rely on capacity that we are building ourselves, and so that means that the amount of compute that we own is going to grow around 100% in the next five years," Mensch said, adding that the company would train "bigger and faster models." He also expressed confidence in Mistral's growth prospects, stating that the company is on track to surpass $1 billion in annual recurring revenue before the year ends. "We're very confident that the fundraising we are doing today is also accelerating and enabling further growth down the line in 2027," he told CNBC.

This funding round comes on the heels of a year marked by rapid infrastructure expansion for the Paris-based company. Just a year ago, Mistral's Series C round, led by ASML, valued the company at €11.7 billion. Tuesday's announcement nearly doubles that figure, signaling a dramatic acceleration in investor appetite for European AI champions. Earlier this year, Mistral completed an $830 million debt raise to finance a new data center in Bruyères-le-Châtel, outside Paris, equipped with 13,800 Nvidia GB300 GPUs. A second facility, with a price tag of €1.2 billion, is under development in Sweden, and the company is targeting a combined 200 megawatts of European capacity by the close of 2027.

Mistral operates across 20 countries and counts more than 125 enterprises as customers, including Airbus, ASML, and HSBC. The company positions itself as an independent, European-rooted alternative in a field otherwise dominated by American and Chinese players, promoting open-weight models and championing what it describes as "sovereign AI" — an architecture that keeps data, infrastructure, and deployment decisions in the hands of its customers. The company is also expanding its infrastructure through a strategic partnership with Microsoft, under which Microsoft will use capacity from Mistral's European data centers to serve its cloud and AI customers, with Mistral's models integrated into Microsoft Foundry and Copilot Studio.

Industry analysts view this record round as a pivotal moment for Europe's AI ecosystem, demonstrating that homegrown startups can attract global capital at scale while maintaining strategic independence. The infusion of funds into owned compute infrastructure, rather than relying solely on third-party cloud providers, signals a shift toward vertical integration in the AI sector — a trend that could reshape competitive dynamics across the industry.
