Microsoft to Invest $4 Billion in Second AI Data Center in Wisconsin

Microsoft is doubling down on its artificial intelligence infrastructure with a $4 billion investment in a second AI data center in Wisconsin. This brings the company's total commitment in the state to over $7 billion as demand for AI compute capacity surges. The new facility, slated for completion by 2027, mirrors the scale of its $3.3 billion predecessor in Mount Pleasant—which will house hundreds of thousands of Nvidia's Blackwell GPUs when operational in 2026.

The tech giant is implementing power-efficient solutions to mitigate energy price impacts, including prepaying for electrical infrastructure. "If intelligence is the log of compute… it starts with a lot of compute," CEO Satya Nadella noted in a tweet highlighting Microsoft's rapid GPU fleet expansion—equivalent to adding two nuclear power plants' worth of capacity last year alone.
