Menomonie, Wis. — City Blocks $1.6 Billion AI Data Center Plan

Menomonie, Wisconsin, a city of about 17,000 people in the state's northwest, has turned back a proposed $1.6 billion artificial intelligence data center campus after local officials and residents pushed for answers the developer would not give, according to the Guardian. The project would have covered 320 acres and used an estimated 75,000 gallons of water a day, making it the largest development proposal in the city's roughly 150-year history, the Guardian reported.

Who was behind the Menomonie data center project?

The developer identified itself to local officials only as Balloonist LLC, a shell company incorporated in Delaware, according to the Guardian. The identity of the parent corporation funding the campus was known to a small number of people, including two city officials who had signed nondisclosure agreements with Balloonist, the outlet reported. Sydney Brennan, a 22-year-old newly elected Menomonie councilwoman, learned of the project in the spring of 2025 when she was invited to a meeting with Balloonist consultants pitching the campus, the Guardian reported. Brennan and her fellow council members had not been told who the ultimate tech-industry client was, according to the account.

What concerns did city officials raise?

At that meeting, Brennan questioned the consultants on water use, noise pollution and the strain the facility would put on Menomonie's electrical grid, the Guardian reported. Balloonist's plan included buffer zones meant to reduce noise and a pledge to fund any upgrades needed to the city's power grid, according to the outlet. The water-use figure cited to officials — 75,000 gallons per day — became a focal point for residents weighing the tradeoffs of hosting a hyperscale AI facility, the Guardian reported.

Has the same company used NDAs in other Wisconsin cities?

NDAs tied to data center negotiations were reportedly signed in at least four other Wisconsin cities, according to the Guardian. In one of them, Beaver Dam, city officials also signed nondisclosure agreements with Balloonist LLC over a separate $1 billion data center project, the outlet reported. The company behind that Beaver Dam proposal was later revealed to be Meta, the parent company of Facebook, according to the Guardian.

Why does this fit a national pattern?

The Guardian frames the Menomonie outcome as part of a broader wave of local resistance as technology companies compete for cheap land and power to build AI data centers across the country, often relying on shell entities and confidentiality agreements to negotiate before a project becomes public. That competition for infrastructure has coincided with enormous capital commitments at the top of the AI industry: OpenAI has reportedly lowered the target for its newest funding round to $20 billion, HTT News reported, underscoring how much money is still chasing AI compute capacity even as individual projects run into local opposition over water, power and transparency.

By the numbers

• $1.6 billion — proposed cost of the Menomonie AI data center campus pitched by Balloonist LLC, per the Guardian
• 320 acres — size of the proposed Menomonie site
• 75,000 gallons — estimated daily water use cited to Menomonie officials
• $1 billion — cost of the separate Balloonist-linked data center project in Beaver Dam, Wisconsin, later tied to Meta
• 17,000 — approximate population of Menomonie, Wisconsin
• 4+ — other Wisconsin cities where NDAs tied to data center negotiations were reportedly signed

What happens next for AI data center siting?

The Guardian's reporting does not specify a single formal vote date in the material reviewed, but it documents that Menomonie's scrutiny — driven by a councilwoman pressing consultants on water, noise and grid questions before the parent company's identity was disclosed — preceded the project's collapse. The Beaver Dam case shows the same shell-company structure, Balloonist LLC, was used in multiple Wisconsin municipalities before Meta's involvement became public, raising questions for other cities currently negotiating similar agreements under confidentiality terms. Whether other communities follow Menomonie's path of public pressure, or whether developers adjust disclosure practices first, remains to be tested as more hyperscale proposals move through small-city council chambers.
