What the source record says
End operator undisclosed behind Balloonist LLC (a Delaware foreign LLC). Multiple outlets note Balloonist's Delaware address and registered agent match prior Meta data-center SPV patterns, but NO source names Meta or any operator - recorded as undisclosed. A council member said the end user is 'one of the top tech giants' without naming them. Status corrected from the ledger's 'permitted' to 'proposed': the original I-1 rezoning was superseded by a January 2026 I-4 ordinance; no building permits were ever issued. Proposed investment up to $1.6B and 50-75 FTE jobs are developer projections (not recorded as firm fields). No MW capacity disclosed. Site: ~324 acres along County Highway B (annexed from Town of Red Cedar Aug 2025). Coordinates are the Menomonie centroid. aiClassification 'likely' rests on hyperscale scale + 'tech giant' attribution, not an explicit AI-workload statement.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
