Microsoft Revamps Foxconn Site into World’s Most Powerful AI Data Center
Microsoft announced its Fairwater AI data center, touted as the world’s most powerful, will open in early 2026 at the former Foxconn LCD factory in Wisconsin. The $3.3 billion project spans 1.2 million square feet across three buildings on 315 acres and houses “hundreds of thousands” of Nvidia GB200 GPUs linked by massive fiber capacity. Microsoft says the cluster is ten‑times more powerful than the fastest supercomputer. A closed‑loop cooling system is highlighted as a sustainable feature, aiming to minimize water waste while powering massive AI training workloads.
