OpenAI Stargate: Status of US Sites

The $500 billion Stargate project, driven by OpenAI, Oracle, and SoftBank, is expanding to 7 sites across the United States, targeting over 9GW of power capacity by 2029. Currently, 0.6GW is already operational in Abilene, Texas, and development is underway at all remaining sites.

This scale is described as comparable to New York City's peak power demand, and capable of housing compute equivalent to 20 million Nvidia H100s. The project serves as a case study in how gigawatt-scale AI data centers are being realized in the US, with on-site natural gas power to avoid grid connection delays and closed-loop liquid cooling to reduce water-use controversy emerging as key design choices.

Looking at each site, Abilene is the flagship site, with 4 of 8 buildings already operational and equipped with Blackwell chips. Power currently comes from a mix of on-site natural gas and grid power; expansion was originally planned up to 2.1GW, but capacity has recently been redirected to other regions.

Other major sites are rapidly taking shape as well.

• Shackelford County, Texas: 2GW, targeting Q4 2028. Spanning 1,200 acres, 10 buildings are under construction, powered by an on-site natural gas microgrid.
• Doña Ana County, New Mexico: 2.2GW, targeting Q4 2028. Part of Project Jupiter, 4 large buildings are planned, with foundation work currently underway. This site also uses two natural gas microgrids.
• Milam County, Texas: 1.2GW, targeting Q4 2028. A fast-build site operated by SB Energy, with first building delivery mentioned by the end of 2025.

According to the 2025 announcement, SoftBank owns the hardware at Milam County and Ohio, while Oracle handles the hardware at the remaining sites. Ultimately, all sites are tied together as infrastructure for OpenAI workloads, and Stargate is evolving not as a single data center, but as a multi-hub network of AI infrastructure across the US.
