  1. An O'Leary Digital affiliate filed a new water-rights change application with the Division of Water Rights describing 11 data center clusters and 7.5 GW of generation; close to 200 protests were logged within days. (KSL.com (republished by Deseret News), Oct. 16, 2026; The Salt Lake Tribune, Oct. 20, 2026)

  2. The company said the project was in pre-development, with Phase 1 generation limited to 1.5 GW; three related lawsuits remained unresolved. (KSL.com (republished by Deseret News), Oct. 2, 2026)

  3. The county and O'Leary's side asked the 1st District Court to dismiss the referendum lawsuit. (FOX 13 News, Aug. 3, 2026)

Conflicts and open questions

  • Coordinates are from the internal lead pointer; they fall within T12N R7W SLM, inside the township range listed in MIDA plan Exhibit A (T12N-T13N, R7W-R10W), in Box Elder County. Parcels were not individually mapped.
  • Acreage: MIDA plan Exhibit A gives 40,691.72 private acres plus 1,278.96 acres of military/state land; O'Leary told the Tribune in July 2026 that about 10,000 acres would be built on, and in October the Tribune reported about 11,000 acres under purchase agreements.
  • Resolution numbers confirmed from the county's May 4, 2026, agenda and approved minutes: Resolution 26-11 (consent to the project area) and Resolution 26-12 (approving Interlocal Agreement 26-15). The April 27 agenda had listed the consent item as Resolution 26-10, while the special-meeting order attached to the April 27 minutes called it 26-11.
  • Power figures vary: 7.5 GW (The Logic; Oct. 2026 water filing), 7.5 to 9 GW (county release via Utah News Dispatch), up to 9 GW long term with 1.5 GW in Phase 1 (KSL, Oct. 2026).
  • The draft MIDA-county interlocal agreement in MIDA's April 24 packet estimates county revenue of about $30 million a year from a roughly 3 GW first phase and about $108 million a year at about 9 GW, with MIDA agreeing to adjust its tax to guarantee those minimums. These are draft-agreement estimates, not the adopted text.

The full record

Status note
On May 4, 2026, Box Elder County consented to the MIDA Stratos project area (Resolution 26-11) and approved the interlocal agreement (Resolution 26-12); the company says it is in pre-development, filed a new water-rights change application in October 2026, and still needs state approvals before Phase 1.
Power note
About 1,100 MW of data center buildings, taken from the company's May 2026 renderings (ten 100 MW buildings plus one more 100 MW building); unconfirmed by any filing. Generating capacity is reported separately and is larger: KSL (Oct. 2026) reports Phase 1 generation limited to 1.5 GW and up to 9 GW long term; The Logic and the October 2026 water filing describe 7.5 GW.
