What Microsoft-Mistral Deal Means For Europe's Data Centres

In a move that deepens an already solid partnership, Microsoft and Mistral have announced a deal to strengthen AI infrastructure across Europe.

Alongside making Mistral's AI models more widely available through Microsoft's platforms, the deal supports investment in European data centre capacity as demand for AI compute soars.

The partnership also reflects wider efforts to give organisations more options for running AI workloads within European infrastructure.

Data centre investment supports AI growth

The agreement includes a multi-billion-dollar commitment to expand AI infrastructure in Europe, building on the companies' partnership announced in 2024.

Earlier this year, Mistral said it will invest US$1.43bn in new data centres in Sweden.

Microsoft also announced plans last year to increase its European data centre capacity by 40% over the next two years, supporting growing demand for cloud and AI services.

To underpin the infrastructure expansion, Mistral is adding GPU capacity using thousands of NVIDIA Vera Rubin GPUs to increase compute power for AI workloads.

Ian Buck, Vice President of Hyperscale and High-Performance Computing, NVIDIA, says: “Agentic AI is driving unprecedented demand for high-performance, energy-efficient AI infrastructure.

“By deploying NVIDIA Vera Rubin systems at scale, Mistral and Microsoft will give customers the computing foundation they need to build and run the next generation of AI across Europe and beyond.”

The partnership also extends Mistral's software availability. Mistral Medium 3.5 and OCR 4 are now available through Microsoft Foundry, while Mistral Medium 3.5 is also available in Microsoft Copilot Studio.

Mistral's OCR 4 supports structured document processing and automation workflows, while Mistral Medium 3.5 offers an open-weight model that enables organisations to build and deploy AI applications with sovereign deployment options.

Arthur Mensch, Co-Founder and CEO of Mistral, says: “Our mission has always been to put frontier AI in the hands of every organisation while keeping them in control of their technology.

“With Microsoft as our partner, our models reach enterprises and public institutions at global scale, delivered through a platform trusted for the most demanding, regulated workloads and available everywhere our customers operate.”

Sovereign cloud and European infrastructure

The infrastructure programme aligns with wider efforts across Europe to reduce dependence on overseas technology providers.

Brad Smith, Vice Chair and President, Microsoft, says: “Europe should have access to the world’s most capable AI without compromising control over their data, operations or digital future.

“By bringing Mistral’s frontier European models into our sovereign cloud portfolio and enabling them across public cloud, cloud-connected and fully disconnected environments, we are honouring the European Digital Commitments we made and giving customers a trusted foundation for AI they can operate on their own terms.”

The EU is reportedly examining ways to reduce Europe's dependence on technology supplied from outside the continent.

In June, the Guardian reported that the European Commission wants to ensure no foreign government or company can access a "kill switch" capable of disrupting critical technology services, aiming to cut dependencies on the US and China.

McKinsey also identified trust, security and national dependency as key barriers to AI adoption across Europe, arguing that sovereign AI capabilities can offer greater national, economic, operational and technical independence.

Investment interest grows around Mistral

The expanded partnership also comes as Mistral attracts wider investor interest.

The Financial Times reported that Samsung is discussing an investment worth hundreds of millions of euros as part of a fundraising round that could value the French AI company at around €20bn (US$22.8bn).

Commenting on the wider market, Ashish Patel, a Managing Director in Houlihan Lokey’s Capital Solutions Group, says: “Increasing pressure from European governments is driving the agenda around European sovereignty, including efforts to reduce dependency on critical technologies that have historically been supplied by the US and China.

“Companies such as Mistral and Lovable have been vocal about the importance of sovereign European technologies, and this shift in market sentiment is increasingly being reflected in capital allocation decisions.”
