AI Data Centers in Wisconsin: Every Facility Tracked (2026)

Wisconsin is home to one of the most powerful AI data center buildouts in the country, anchored by a Racine County campus dubbed "the world's most powerful AI datacenter for training." Ban the Bots' data center map tracks four major AI data center facilities across Wisconsin as of 2026 — a combined 5,320 megawatts of tracked capacity, more than Texas's tracked 4,500+ megawatts, though still behind Virginia's tracked 8,300+ megawatts, the largest concentration in the country.

Which AI companies are building data centers in Wisconsin?

Three companies operate the four major AI data center facilities tracked on this site in Wisconsin: Microsoft, which operates two separate campuses in Racine County; Oracle, building a Stargate data center in Ozaukee County in partnership with Vantage Data Centers as part of Oracle's $300 billion-plus partnership with OpenAI; and Meta, building a dry-cooled campus in Dodge County.

Why is Wisconsin attracting AI data centers?

Based on the facilities tracked here, a few factors stand out:

• Freshwater access: Microsoft's Wisconsin Data Center Campus in Mount Pleasant draws directly from Lake Michigan via the Racine Water and Wastewater Utility, a resource not every inland state can offer at scale.
• Available land, including former farmland: Microsoft's Mount Pleasant campus was built on former farmland, and Meta's Beaver Dam site spans a 520-acre parcel — both typical of large-scale AI buildouts sited outside dense metro areas.
• A clustering effect: once one operator commits, others follow the same infrastructure. Racine County now hosts two separate Microsoft campuses, and Port Washington in Ozaukee County is home to Oracle's Stargate data center as well as a further Microsoft AI campus planned for the same area.

Water, power, and community concerns

Wisconsin's AI buildout has already drawn real local pushback — and it also includes a notable exception:

• Microsoft's Wisconsin Data Center Campus in Mount Pleasant draws its water from Lake Michigan via the Racine Water and Wastewater Utility. The $3.3 billion project sits on former farmland, and community groups have raised concerns about both the Lake Michigan water draw and the loss of agricultural land.
• Microsoft's Project Fairwater, also in Mount Pleasant, is a far larger undertaking — a $7.3 billion, 315-acre campus with 1.2 million square feet across three buildings, housing hundreds of thousands of Nvidia GB200/GB300 GPUs. Its water source is not specified in this site's tracking data.
• Oracle's Stargate Data Center in Port Washington, developed with Vantage Data Centers, likewise has no publicly specified water source in this site's records.
• Meta's Beaver Dam campus is a genuine counterexample: it uses dry-cooling technology that Meta says eliminates operational water demand entirely, and it pairs that with a wetlands and prairie restoration program on its 520-acre site — a materially different water footprint than the Racine County projects.

Wisconsin AI data center facilities, one by one

• Microsoft Project Fairwater AI Data Center (Mount Pleasant, Racine County; operating): dubbed by Microsoft the world's most powerful AI datacenter for training, this 315-acre campus packs 1.2 million square feet across three buildings with hundreds of thousands of Nvidia GB200/GB300 GPUs. Announced in May 2023, its Phase 1 build (400 MW) went operational in early 2026, with the full build-out that could reach 3,300 MW by late 2027 — a $7.3 billion total investment.
• Oracle Stargate Data Center – Wisconsin (Port Washington, Ozaukee County; under construction): a 1,300 MW campus developed with Vantage Data Centers, announced in September 2025 as part of Oracle's $300 billion-plus partnership with OpenAI. Microsoft is separately planning its own 1,300 MW AI campus in the same Port Washington area.
• Microsoft Wisconsin Data Center Campus (Mount Pleasant, Racine County; under construction): a separate 500 MW, $3.3 billion Microsoft campus announced in May 2023, built on former farmland and drawing water from Lake Michigan via the Racine Water and Wastewater Utility — a combination that has drawn community concern over both water use and agricultural land loss.
• Meta AI Data Center – Beaver Dam (Dodge County; under construction): a $1 billion, 520-acre, 700,000+ square foot campus announced in November 2025, Meta's 30th global data center. Targeted for operation in 2027, it uses dry-cooling technology that eliminates operational water demand and includes a major wetlands and prairie restoration program, at a tracked capacity of 220 MW.

FAQ: AI data centers in Wisconsin

How many AI data centers are in Wisconsin?

Ban the Bots tracks four major AI data center facilities in Wisconsin as of 2026, operated by Microsoft (two campuses), Oracle (with Vantage Data Centers), and Meta, with a combined tracked capacity of roughly 5,320 megawatts.

Where are Wisconsin's AI data centers located?

Racine County (Mount Pleasant) hosts two separate Microsoft campuses, including Project Fairwater. Ozaukee County (Port Washington) hosts Oracle's Stargate data center, with a further Microsoft campus planned for the same area. Dodge County (Beaver Dam) hosts Meta's AI data center.

What is Microsoft's Project Fairwater?

Project Fairwater is a Microsoft AI data center in Mount Pleasant, Racine County, that Microsoft has dubbed the world's most powerful AI datacenter for training. Its 315-acre campus houses hundreds of thousands of Nvidia GB200/GB300 GPUs across 1.2 million square feet, with Phase 1 (400 MW) operational in early 2026 and a total planned build-out of 3,300 MW by late 2027, representing a $7.3 billion investment.

Do Wisconsin's AI data centers use a lot of water?

It varies by facility. Microsoft's Wisconsin Data Center Campus in Mount Pleasant draws from Lake Michigan, which has drawn local concern over both water use and the loss of the farmland the campus was built on. Meta's Beaver Dam campus, by contrast, uses dry-cooling technology that eliminates operational water demand and includes a wetlands and prairie restoration program. Water sourcing for Microsoft's Project Fairwater and Oracle's Port Washington campus is not publicly specified in this site's tracking data.

Conclusion: tracking Wisconsin's AI buildout

Wisconsin's AI data center buildout is now large enough, and concentrated enough in Racine and Ozaukee counties, to rank among the most significant in the country — anchored by a facility Microsoft calls the most powerful AI datacenter for training ever built, alongside a genuine counterexample in Meta's dry-cooled, wetlands-restoring Beaver Dam campus.
