TL;DR
SpaceX announced plans for two large AI computing projects: a more than $24 billion facility near Brownsville, Texas, and a roughly $50 billion campus in Cochise County, Arizona. The projects would rely on different power arrangements and face local decisions scheduled for Dec. 9, 2026; some details, including Texas facility water use and Arizona power approvals, remain unresolved.
SpaceX said Nov. 12 it is advancing two AI supercomputing projects in Starbase, Texas, and Cochise County, Arizona, describing them as more than $74 billion in planned investment. The proposals would add major computing capacity, but each still faces local review, and important questions about power, water and public incentives remain open.
In Texas, SpaceX says it plans to invest more than $24 billion in computing infrastructure on an approximately 444-acre site near the Port of Brownsville. A Starbase city notice describes the project as a gas-fired power plant and supercomputing facility, with initial-phase capital investment estimated at about $24 billion and possible future expansions. SpaceX says the facility will generate its own electricity rather than draw from the public grid.
The company says the Texas project is intended to train AI systems for applications including medical research, emergency response, manufacturing and national security, and to support testing of technology for future space-based computing. SpaceX reports more than 3,000 construction jobs so far and expects more than 500 permanent jobs once the facility is operating. Those figures are company estimates, not independently verified employment totals.
In Arizona, SpaceX describes a roughly $50 billion campus on about 747 acres near Cochise. The county application was filed by Tombstone Resources L.L.C.; the documents cited in the source material do not name SpaceX, though the company’s project page and Tombstone’s town-hall statement link the project to SpaceX. Plans call for as many as nine computing buildings, built in four phases, with full build-out estimated at about 6 gigawatts of power demand and a 24-gigawatt-hour battery system.
The Arizona application says electricity would come from the grid through Sulphur Springs Valley Electric Cooperative and Arizona Electric Power Cooperative, with a utility-owned substation on the site. It proposes dry cooling without cooling towers and estimates water use of 7 to 10 acre-feet a year at full build-out, mostly for staff. The application projects about 5,500 construction workers at peak, around 250 staff when the first buildings open and about 1,000 employees at full build-out.
SpaceX’s Texas and Arizona plans Power, jobs and local decisions
SpaceX has announced more than $74 billion in planned investment across two AI computing projects. Each faces local review, with questions about infrastructure and approvals still open.
Two different power models
The energy arrangements shape local infrastructure and public review.
- Planned gas-fired plant would generate electricity on site.
- Computing and power-plant capacity are not specified in the city notice.
- Water use for the computing operation remains unstated.
- Grid power proposed through two electric cooperatives.
- Full-build power demand estimated at about 6 gigawatts.
- Dry cooling proposed, with estimated water use of 7 to 10 acre-feet a year.
Jobs depend on build-out
Employment figures are projections or company estimates, not verified totals.
Construction and operations
SpaceX reports more than 3,000 construction jobs so far and expects more than 500 permanent jobs.
Phased workforce
The application projects about 5,500 construction workers at peak and around 1,000 employees at full build-out.
What local officials will consider
The scheduled proceedings may clarify conditions and next steps; they do not guarantee approval.
Cochise County’s Planning and Zoning Commission is scheduled to hear the proposal.
Starbase’s City Commission is scheduled to consider a property tax abatement.
Utility, city, county and regulator documents may clarify capacity, emissions, incentives and approvals.
Two Power Models, Two Local Stakes
The proposals show how a single company is pursuing large AI computing projects through different local power arrangements. In Texas, SpaceX says the facility would produce its own electricity using a gas-fired plant. In Arizona, the campus would take power from the grid through cooperatives. Those differences matter to residents and officials weighing potential jobs and investment against energy demand, infrastructure needs and local environmental effects.
The projects also put local decision-makers at the center of a high-value technology development. The Arizona campus’s stated full-build power requirement is about 6 gigawatts, while the Texas facility’s computing capacity and power-plant capacity are not specified in the city notice cited here. The scale of the plans makes details such as utility arrangements, air emissions, water supply and tax treatment relevant to the public review, rather than merely technical matters.
SpaceX has also tied the projects to its broader AI ambitions. The company has presented space-based computing as a longer-term response to electricity constraints, while describing the Texas site as a place to develop and test related technologies. The immediate plans, however, are for large facilities on land in Texas and Arizona, with local infrastructure and approval processes shaping whether and how they proceed.

From Orbital AI to Ground Sites
SpaceX announced on Feb. 2 that it had acquired xAI. In that announcement, the company argued that terrestrial electricity demand for AI could not be met in the near term without imposing hardship on communities and the environment, and promoted data centers in orbit as an answer. The two projects announced in November are large-scale terrestrial facilities. SpaceX presents the Texas site as also helping develop technology for future space-based computing, rather than describing it as a replacement for that goal.
The announcement comes as AI has become a major part of SpaceX’s business, according to the source report. Reuters reported that the company’s AI segment generated more than half of its revenue in the third quarter. The source article says it checked the project announcement against SpaceX statements, the Arizona county application and a Starbase city notice. The projects are at different stages of public documentation: the Arizona filing is under Tombstone Resources’ name, while Starbase’s notice directly describes a gas-fired plant and computing facility.
“Together, they represent more than $74 billion in planned American investment.”

Capacity, Water and Incentives Unsettled
Several project details remain unavailable or dependent on review. The Starbase notice does not specify the Texas computing facility’s capacity or the gas plant’s generating capacity, and SpaceX has not stated how much water the computing operation itself would use. A local outlet, The 956 Report, reported figures from an air registration filed with the Texas Commission on Environmental Quality, including a temporary turbine setup and a later proposed configuration; those reported figures are not listed in the city notice summarized here.
The size and terms of a proposed Texas property tax abatement are also not established in the supplied material. In Arizona, the county application estimates water use and power needs, but the material does not establish whether the relevant utility arrangements or any required regulatory approvals are final. SpaceX’s promise of lower electricity bills for local cooperative members depends on an electricity deal whose approval status is unclear. The projects’ construction schedules, final designs and completed job totals are also not confirmed.
Local Reviews Set for December 9
Both projects face local proceedings scheduled for Dec. 9, 2026. The Cochise County Planning and Zoning Commission is set to hold a hearing on the Arizona proposal. In Texas, the Starbase City Commission is scheduled to consider a property tax abatement. Those proceedings could clarify conditions, incentives and the next steps for each development, but the supplied information does not say that either project will receive all approvals on that date.
Readers should watch for decisions and supporting documents from the county, city, utilities and relevant regulators. Further filings may provide more precise information about the Texas plant’s capacity and emissions, the computing sites’ construction phases, and the Arizona power arrangement tied to promised bill reductions. Until then, the announced investment and employment figures describe proposed plans rather than completed facilities or guaranteed outcomes.
