Microsoft Invests $7.3 Billion Wisconsin Datacenters

The US tech giant Microsoft has said that the company was in the final phases of building the $3.3 billion Fairwater, the world’s most powerful AI datacenter in Mount Pleasant, Wisconsin, which is part of a region forged by generations of hard work and ingenuity.

This facility, which will be completed in early 2026, is more than a technological feat and promises to grow responsibly, invest deeply, and create opportunities for Wisconsin and for the US, Microsoft said.

The company also said that it was committing an additional $4 billion to be spent in the next three years to build our second datacenter of similar size and scale, bringing our total investment in Wisconsin to more than $7 billion.

Engineered to train the next decade of artificial intelligence, the Mount Pleasant facility will house hundreds of thousands of the world’s most powerful NVIDIA GPUs, operating in seamless clusters connected by enough fiber to wrap the planet four times over.

These processors will handle training for frontier AI models — delivering ten times the performance of today’s fastest supercomputers, Microsoft Vice Chair and President Brad Smith said on Thursday.

This datacenter is designed to help AI researchers and engineers build the world’s most advanced models, test ideas faster, and do it all more efficiently. It’s not just about running AI — it’s about creating it.

“This is where the next generation of AI will be trained, setting the stage for breakthroughs that will shape the future. New discoveries in medicine, science, and other critical fields will start right here, with the models we train in Wisconsin,” Smith said.

In other words, for the average Wisconsinite, it means new jobs, new skills, and new opportunities at home. From union construction roles to long-term careers in operations and IT, this facility is creating pathways for Wisconsinites to be part of the future of technology.

It means students at Gateway Technical College can train for high-demand roles through Wisconsin’s first Datacenter Academy. Local companies, from manufacturers to start-ups, can partner with Microsoft engineers to turn AI ideas into real solutions.

Built for Sustainability

According to Smith, this datacenter is distinctive not just its scale or speed. It’s how thoughtfully it’s built, with both people and the planet in mind. From day one, sustainability has been central to its design.

More than 90% of the facility will rely on a state-of-the-art closed-loop liquid cooling system, filled during construction and recirculated continuously. The remaining portion of the facility will use outside air for cooling, switching to water only on the hottest days, minimizing environmental impact and maximising operational efficiency.

The result is a technological milestone — a datacenter with enough fiber cable to circle the Earth four times, yet its annual water use is modest, requiring roughly the amount of water a typical restaurant uses annually or what an 18-hole golf course consumes weekly in peak summer.

Our commitment to be a good neighbour in Racine County is one of the reasons Microsoft joined forces with Root-Pike Watershed Initiative Network (WIN) to restore prairie and wetland habitats in Racine and Kenosha counties, funding 20 ecological restoration projects, including Cliffside Park along the shores of Lake Michigan, Lamparek Creek in Mount Pleasant, Kirkorian Park in Village of Sturtevant, and Shagbark Restoration Area in Kenosha.

Finally, to help more Wisconsinites access the world’s most advanced technology being built in their home state, Microsoft has expanded broadband access to more than 9,300 rural residents and delivered next-generation service to 1,200 homes and businesses in Sturtevant — bringing faster, more reliable internet to the places where people live, work, and learn.
