The Stargate AI campus in Abilene is the flagship site of the $500 billion AI infrastructure program backed by OpenAI, Oracle, and SoftBank. As of January 2026, more than 6,400 construction workers were on-site at the Abilene facility, according to Texas Standard reporting citing Texas Monthly contributor Christopher Collins (Source: Texas Standard, January 26, 2026). The campus spans just over 1,000 acres, with eight planned buildings each approximately 500,000 square feet. Oracle’s Larry Ellison confirmed the building specifications at a White House briefing, per Epoch AI’s April 2026 assessment.
Epoch AI’s April 17, 2026 site assessment confirmed that four of the eight Abilene buildings are already operational, with the remaining four targeting completion by mid-2026 (Source: Epoch AI, epoch.ai, April 17, 2026). The campus is currently operating at an estimated 0.3 gigawatts of capacity and is designed to scale past one gigawatt at full buildout. Oracle has a 15-year lease agreement for the site and has deployed Nvidia GB200 GPU racks for early AI training workloads. At the $3 to $4 billion construction cost estimated by Epoch AI, this is one of the largest single-site construction investments in Texas history.
“The most advanced Stargate site — in Abilene, Texas — is already operating at an estimated capacity of 0.3 gigawatts. Four of the eight buildings are already operational. The campus has the potential to scale past a gigawatt of capacity, with the remaining buildings targeting completion by mid-2026.”

A campus of this scale generates sustained aggregate demand across multiple phases. Site preparation for each building pad requires engineered sub-base with precise compaction specifications. Internal access roads for a facility that will house hundreds of thousands of GPU racks and their support infrastructure require road base and crushed stone across the full site perimeter. Utility corridors for power and cooling systems require utility sand and select fill. That work is not concentrated in one phase. It runs across the full construction timeline, which at Abilene means it has been active since 2024 and continues through mid-2026 as the remaining buildings are completed.
The Abilene market is also not carrying this demand alone. Epoch AI confirmed that a separate Stargate site in Shackelford County, just across the county line from Abilene, involves a 1,200-acre Vantage campus with ten buildings and a first building delivery date of late 2026 (Source: Epoch AI, April 17, 2026). That site adds a second major construction demand source to the same regional aggregate and trucking pool that serves Abilene.
West Texas construction markets operate differently from DFW or Austin. Pit networks and trucking capacity are less dense. Projects of this scale in Taylor County and Shackelford County depend on coordinated material sourcing and advance delivery scheduling more than markets with abundant nearby supply. The contractors active on these campuses and the supporting infrastructure work they generate need sourcing relationships confirmed before their job schedule is set.
The Stargate campus in Abilene is one of the largest active construction sites in Texas. With 6,400 workers on-site and four more buildings targeting completion by mid-2026, the aggregate demand from this market is not winding down. It is still running.
