Microsoft finishes first Racine County data center, launches Fairwater

Microsoft announced that its Fairwater data center in Mount Pleasant, Wisconsin, is now fully operational, marking the completion of the first of up to 15 planned facilities in Racine County [1].

Scale and economic impact

The 315‑acre campus houses a more than 1‑million‑square‑foot structure that Microsoft says is the “world’s most powerful supercomputer” for AI workloads [4]. The site is valued at about $1.224 billion for tax purposes, generating an annual tax bill of $19.75 million and making Microsoft the largest taxpayer in Mount Pleasant and Racine County [1]. The company has pledged over $7.3 billion for a series of data centers in the region, with plans for up to 15 additional facilities over the next decade [1][2].

Construction employed roughly 10,000 workers over two years, and the operational center now supports about 375 full‑time employees, a number expected to rise to roughly 800 once the second data center—currently under construction and slated for completion in 2028—comes online [1][2][3]. Microsoft estimates the combined spend on hyperscale construction in Wisconsin will reach $4.7 billion between 2024 and 2028 [3].

Competitive and strategic context

The Fairwater campus joins a broader Great Lakes push for AI‑driven data capacity, following similar projects by Meta and Vantage Data Centers in nearby Wisconsin towns [3]. By consolidating hundreds of thousands of NVIDIA GPUs into a single flat‑network architecture, Microsoft claims the facility will deliver ten times the performance of today’s fastest supercomputer, positioning it to train and run next‑generation generative AI models [3]. The move also aligns with Microsoft’s revenue recognition strategy for AI services, as the additional capacity will allow the company to capture booked revenue from OpenAI and other clients [3].

What to watch

• 2028 – Completion of the second Mount Pleasant data center, which will bring the campus workforce to about 800.
• Future approvals – Whether the village board authorizes the remaining 13 planned centers within the 10‑year window.
• AI workload demand – How quickly Microsoft can fill the new capacity with OpenAI and other enterprise AI contracts.

Microsoft’s Fairwater launch underscores Wisconsin’s emergence as a hub for AI infrastructure, but the long‑term impact will hinge on the pace of AI demand and the company’s ability to scale the planned campus without triggering community pushback over energy and water use.
