Why Texas: The Logic of AI-Industrial Concentration

Overview

Texas Hosts the Largest Projects

SpaceX is building its $16.8 billion Terafab fab at the retired Gibbons Creek power plant in Grimes County. Samsung has committed about $37 billion to its Taylor foundry in Williamson County, backed by a $4.745 billion federal CHIPS award, and Texas Instruments has run its SM1 fab at Sherman since December 2025. Xebec Realty is developing the 33,000-acre Sandow Lakes campus on the former Alcoa site at Rockdale (Milam County).

Data center campuses follow the same map: Stargate Abilene (Taylor County), Fermi America's proposed 11 gigawatt (GW) Project Matador near Amarillo, Tract's 2 GW Caldwell County park, Vantage's 1.4 GW Frontier campus in Shackelford County and Meta's Temple data center, opened July 2026 on grid power. Tesla is expanding Giga Texas in Travis County. No other state holds a comparable set of gigawatt-scale commitments.

Most of these sites reuse infrastructure from earlier Texas industry, the pattern covered at Brownfield Inheritance. Greenfield development in the US now loses years to interconnection, transmission, water rights and permits; inherited sites skip most of that wait.

Site selection

Six Constraints Every Site Must Pass

Each constraint is a gate, not a tradeoff: a site that fails one is out regardless of the others. A leading-edge fab at 100,000 wafer starts per month (WSPM) draws roughly 0.5 to 1 GW and 5 to 10 million gallons per day (MGD) of ultra-pure water (UPW); the largest AI data centers draw 1 to 5 GW.

Time to power binds hardest. A greenfield load of several hundred megawatts (MW) can wait five to seven years or more for Electric Reliability Council of Texas (ERCOT) interconnection, and 8 to 10 years once new transmission, substations and contested permits are added. Rules for large loads are covered at ERCOT Energy Sovereignty and ERCOT Large Load Interconnection.

Water rights bind almost as hard. Texas allocates surface water by prior appropriation, so new senior rights are nearly impossible to obtain and most candidate sites compete with cities, farms and existing industry. Samsung Taylor needed new supply arranged through the Brazos River Authority and the City of Taylor, and each added fab in the Williamson County corridor faces a tighter supply; detail is at Texas Water Supply and Stress.

Contiguous land near a metro is scarce nationally. TSMC Arizona uses about 1,100 acres for two fabs and Samsung Taylor about 1,200; most US parcels of several thousand acres are federal land, petrochemical zones or farmland with no power or water in place. Workforce sorts sites the same way: Phoenix, Austin and Albany have deep chip labor pools, while Sherman, Hillsboro, Boise, Licking County and the Brazos Valley are still building theirs.

Retired Industrial Sites Cut the Power Wait

Coal generation, aluminum smelting, oil and gas and the wind buildout left Texas with transmission, water rights and large parcels that new projects now reuse. Many of those plants closed between 2008 and 2018, and remediation and property sales were done by the time AI demand arrived. Reuse cuts time to power from 5 to 10 years to one to three.

Terafab shows the full pattern. The Gibbons Creek reservoir was built by TMPA to cool the coal plant, its water rights pass with the property, and the site connects by Highway 30 to the US Highway 79 freight corridor, with Texas A&M engineers nearby. Sandow Lakes repeats it at five times the acreage, with rail left from Alcoa's bauxite logistics and more than 30 million square feet planned in its first phase.

Each commitment also strengthens the next: Samsung's original $17 billion Taylor plan pulled Oncor transmission into eastern Williamson County, and that capacity now serves data centers along the Georgetown-Hutto-Taylor corridor. The same effect is building around RELLIS in the Brazos Valley.

Alternatives

Peer States Fail at Least One Gate

Moving a project out of Texas adds 5 to 10 years through power and water alone, longer than chip and AI operators can wait. Arizona matches Texas on permitting speed and CHIPS funding but not on water or proximity to Tesla and SpaceX. SemiconductorX compares fab buildouts by state in US Semiconductor Reshoring.

Each Texas commitment widens the gap. Workforce, suppliers, transmission and federal CHIPS flows concentrate further with every new fab or campus, so the alternatives grow relatively weaker over time. Texas's lead comes partly from historical accident, where earlier industries happened to retire just as AI demand arrived, and partly from deliberate state economic development policy.

Policy

State Incentives Stack on Federal CHIPS Money

Texas has kept a favorable framework for large industrial projects across several administrations and legislative sessions, which matters to operators committing tens of billions over decades. Federal CHIPS funding has flowed to Samsung Taylor and TI Sherman, and research anchors at UT Austin's TIE NGMM and the Texas A&M Semiconductor Institute support further awards. Combined engineering enrollment across the UT and A&M systems and other Texas programs exceeds 100,000 students.
