Microsoft expands Wisconsin AI data center investment to $7 billion
Microsoft announced plans to build a second major artificial intelligence data center in Wisconsin, raising its total investment in the state to more than $7 billion. The new $4 billion facility will join a $3.3 billion data center already under construction in Mount Pleasant, Racine County, first unveiled last year.
The initial data center is expected to open in 2026 and employ about 500 people, while the addition of the second will expand staffing to around 800. Microsoft says the combined site will eventually host the world’s most powerful AI supercomputer, linking together hundreds of thousands of Nvidia chips.
The development comes on land once earmarked for Foxconn’s highly publicized $10 billion factory, a project dramatically scaled back after initial political fanfare during Donald Trump’s presidency. When President Joe Biden attended Microsoft’s first announcement last year, he highlighted Foxconn’s retreat as a cautionary tale while framing Microsoft’s plan as a sign of renewed investment.
Microsoft said it will pre-pay for electrical infrastructure to avoid burdening local customers with higher power bills and will use Wisconsin’s cold climate for energy-efficient cooling. Annual water consumption will be capped at roughly the level of an average restaurant. To offset its energy use, the company will also build solar power elsewhere in Wisconsin, though Microsoft President Brad Smith noted new fossil fuel generation—specifically liquefied natural gas—will still be part of the mix.
While the 800 permanent jobs fall short of the thousands promised by Foxconn, Smith emphasized the importance of ongoing skilled labor positions, including pipefitters and electricians, needed for both construction and long-term maintenance.
