OpenAI Stargate Wisconsin
Announced; Oracle Corporation is recorded as owning the AI hardware inside this site
Description quoted from Epoch AI Frontier Data Centers
The Stargate site in Port Washington, Wisconsin is one of a set of 5 Stargate sites that were announced in tandem. The developer of this site is Vantage, and they state the planned IT load, power density, and other features of the campus on their website. We estimate the date at which the full site is operational based on the environmental analysis filed, which splits the site into two projects. Project 1, which is the first 3 buildings, has a planned completion date of Q3 2028. Project 2, which is the last building, has a planned completion date of Q4 2028.

Methods and sources
Ownership roles
Title identifies the legal owner of the site; operation identifies who runs it. AI-hardware ownership follows the catalog’s attribution of the machines inside, whose owner may lease the facility.
Each role requires its own attribution. An operator named in a source supplies evidence of operation only.
Parent companies
Ownership checks start with each company named at the site and follow recorded parent relationships. A company holding several roles is checked once. Its linked company page lists the relationships and their sources; further parents may remain undocumented.
Level 1 identifies a company at the site, level 2 its parent, and each further level another parent. Export-control designations and government investments are assigned to the company concerned.
Missing values
Unrecorded roles remain blank. Findings whose company position is unresolved stay in the list with that position labelled unknown.
Publication limits
Subscription corporate data helps identify parent relationships and sovereign investments. Publication is limited to relationship classes and supporting public sources; licensed records, identifiers and values are withheld.
