Where Are OpenAI’s Five New Hyperscale Campuses Being Built?

Yesterday, September 23, OpenAI publicly announced five new hyperscale infrastructure sites as part of its next-generation “Stargate” buildout. Each designed to accelerate AI system training and inference at unprecedented scale. Backed by Oracle and SoftBank, this expansion represents more than $65 billion in U.S. infrastructure investment and is expected to add over 4.2 GW of new compute-linked energy demand.

While OpenAI did not name the precise locations, Aterio has been independently tracking each development through a combination of satellite imagery, land transactions, utility interconnection filings, and developer announcements. Based on this multi-source validation, we’ve mapped all five campuses.

Scope and Scale: What Each Campus Is Really Building

Behind the announcements, the data reveals the real footprint of OpenAI’s Stargate campuses, measured in megawatts (MW) and buildings across key U.S. locations:

• Vantage Shackelford Campus (Shackelford County, TX) - Under Construction
  • 10 buildings
  • Estimated 1,400 MW of power capacity
  • Site prep confirmed via satellite on September 9
• Vantage Port Washington Campus
  • 11 buildings
  • Estimated 1,300 MW of power capacity
  • Permitting activity and utility filings in motion
• Project Jupiter (Dona Ana County, NM)
  • 4 buildings
  • MW not yet disclosed, but projected >1 GW
  • Officially announced by BorderPlex Digital Assets and STACK Infrastructure on August 25
• SB Energy Global Data Center Campus (Milam County, TX)
  • 10 buildings
  • Estimated 900 MW of power capacity
  • Part of SoftBank’s 1.5 GW rollout over the next 18 months
• Foxconn / Lordstown Site (Lordstown, OH)
  • Estimated ~6 buildings
  • Estimated ~600 MW of power capacity
  • Owned by SoftBank-affiliated entity (Crescent Dune LLC)
  • Part of SoftBank’s 1.5 GW rollout over the next 18 months

What We’re Seeing on the Ground

Vantage Shackelford Campus (Texas)

Confirmed via satellite imagery captured September 9, land grading began mid-August on this $25B hyperscale site. The Shackelford project is a centerpiece of the Stargate network and will likely exceed 1 GW of power draw once fully built out. The campus sits in a fast-emerging corridor between Abilene and Eastland County, near recent substation expansion filings.

Project Jupiter (New Mexico)

BorderPlex Digital Assets and STACK Infrastructure officially announced Project Jupiter on August 25, describing it as a “next-generation AI campus” designed with responsible power and water usage principles. Though OpenAI was not named, the $25B scale, Oracle’s involvement, and regional siting match Stargate project criteria. Located in Dona Ana County, this site expands OpenAI’s reach into the Southwest, where grid balancing and solar baseload potential are strategic assets.

SB Energy Global Campus (Milam County, TX)

The second of SoftBank’s U.S. deployments, this $3B facility is part of a combined 1.5 GW capacity delivery planned over the next 18 months. Permitting filings show intent for immersion-cooled AI racks and modular data hall delivery. As of September, local land disturbance permits and utility interconnection requests are in motion.

Vantage Port Washington Campus (Midwest U.S.)

One of the five Stargate campuses is located in Port Washington, Wisconsin where Vantage Data Centers acquired the site from Cloverleaf in 2025. The project is targeting 1.3 GW of capacity by end of 2027, with plans to scale to 3.5 GW long term. A $3.8B debt package arranged by JPMorgan, MUFG, and Mizuho, reported by Bloomberg on September 23, is expected to finance Oracle’s U.S. buildout for OpenAI, with Port Washington as a key beneficiary.

What Wasn’t Mentioned?

While OpenAI’s five Stargate campuses dominate the spotlight, it’s notable that Crusoe’s $29B Goodnight Campus in Claude, Texas, a project already under construction and widely viewed as architecturally and strategically aligned with Stargate, was not included in the announcement.

As we reported earlier, the Goodnight Campus is a seven-building, 1 GW hyperscale deployment backed by Crusoe with sitework already confirmed via satellite as of September. The exclusion raises questions about whether additional Stargate-class projects are being executed quietly in parallel, or reserved for a future announcement cycle.

For investors, these aren’t just headlines. Stargate-scale projects are actively breaking ground across multiple regions with no signs of slowing down.
