Microsoft’s Wisconsin AI Data Center Campus Now Fully Operational

Microsoft has completed the first data center facility at its Mount Pleasant campus in Wisconsin, a major AI infrastructure project that began limited operations in April and is now fully operational. The milestone is significant because it demonstrates that hyperscalers are converting announced multibillion-dollar AI infrastructure plans into actual operating capacity, at a time when compute capacity remains constrained in the market. The facility incorporates sustainability features including a closed-loop cooling system designed to minimize water use and low-carbon construction materials. The campus location was acquired after a planned large-scale electronics manufacturing project was scaled back, and the site now supports roughly 550 full-time employees.
