TL;DR
SpaceX announced plans for two AI computing campuses: an investment of more than $24 billion near its Starbase, Texas, launch site and a roughly $50 billion campus in Cochise County, Arizona. Both projects face local decisions scheduled for Dec. 9, 2026, while key details—including Texas facility capacity and the Arizona power arrangement—remain unresolved.
SpaceX said Nov. 12 it is advancing plans for two AI computing campuses, one near Starbase in South Texas and another in Cochise County, Arizona, describing the projects as more than $74 billion in planned U.S. investment. The proposals would add major computing demand and, in Texas, a dedicated gas-fired power plant; both require local action, with decisions scheduled for Dec. 9, 2026.
SpaceX puts the Texas project’s planned investment at more than $24 billion. A Starbase city notice estimates approximately $24 billion for initial phases, with possible future expansion, on about 444 acres between Boca Chica Boulevard and the Port of Brownsville. SpaceX says the facility will generate its own electricity rather than draw from the public grid. The city notice describes a gas-fired power plant but does not state its capacity.
SpaceX says the Texas site is intended to train AI systems and test technology for future space-based computing. The company reports more than 3,000 construction jobs so far and expects more than 500 permanent jobs when the facility is operating. Those are company estimates; a completion schedule and the computing site’s capacity have not been provided in the material available.
In Arizona, SpaceX describes a roughly $50 billion campus on about 747 acres near Cochise. A county application filed by Tombstone Resources L.L.C. proposes up to nine computing buildings, each about 493,000 square feet. It describes a first phase of about 1,500 megawatts and a full build-out of approximately 6 gigawatts, with a 24-gigawatt-hour battery system. The application identifies grid delivery through local utilities, not an on-site power plant.
SpaceX Plans Major AI Campus Investments Across Texas and Arizona
SpaceX has announced two planned AI computing campuses. Local decisions are scheduled for Dec. 9, while power, permits and other project details remain open.
Two states, two power plans
The campuses would bring major electricity needs, with different proposed ways to supply them.
- SpaceX says the site will generate its own electricity with a gas-fired plant.
- The plant’s capacity and the computing facility’s capacity have not been provided.
- The application describes utility-delivered power and a proposed full build-out of about 6 gigawatts.
- Utility and regulatory arrangements remain unresolved.
Local impact commitments
The proposals include potential benefits for workers and communities, alongside questions about resources and infrastructure.
Jobs and infrastructure
SpaceX reports more than 3,000 construction jobs so far and expects more than 500 permanent jobs. It says it is contributing to local water and wastewater infrastructure.
Water and power bills
SpaceX says the campus would use dry cooling and has promised lower bills for local cooperative members. The electricity deal and its terms are not settled.
Next local milestones
The scheduled proceedings are the next identified steps; they may not decide every permit or operating detail.
Details still to watch
Project figures are proposed or estimated, and may change as reviews continue.
- Texas generation capacity and the computing site’s water use
- Arizona power delivery arrangements and regulatory decisions
- Conditions attached to local approvals and the Texas tax request
Two States Face Large Power Demands
The plans show the scale of infrastructure SpaceX is seeking for AI computing, an area the company has linked to its broader technology ambitions. A campus consuming up to 6 gigawatts in Arizona would depend on a substantial electricity supply and new utility arrangements. The Texas proposal takes a different approach, with SpaceX saying it will supply its own electricity through a gas-fired plant.
For nearby communities, the stakes include employment, land use, utility investment and environmental effects. SpaceX says the Arizona campus would use dry cooling and avoid industrial groundwater use, and it has promised lower power bills for local cooperative members. In Texas, it says it is contributing to water and wastewater infrastructure. Those commitments could matter to residents, but some depend on permits, utility decisions or project details that are not yet settled.
The projects also put local decision-makers in the position of weighing economic promises against resource and infrastructure questions. Investment figures and job counts come from SpaceX or project documents; they are projections, not evidence that construction or full operations are guaranteed.

From Space-Based AI to Ground Sites
SpaceX’s announcement follows its Feb. 2 announcement that it had acquired xAI. At that time, the company argued that AI’s electricity needs could not be met on Earth without imposing hardship on communities and the environment, and presented orbital data centers as part of its response. The new proposals instead place large computing facilities on land in Texas and Arizona. SpaceX says the Texas site will also support testing of technologies for future space-based computing.
The two projects differ in how they propose to meet power needs. The Texas plan, according to SpaceX and the Starbase notice, includes on-site gas-fired generation. The Arizona application describes electricity supplied through Sulphur Springs Valley Electric Cooperative and Arizona Electric Power Cooperative to a utility-owned substation on the site, with standby generators for outages and testing. The county application names Tombstone Resources, rather than SpaceX; the connection is supported by SpaceX’s project page and Tombstone’s notice of a community town hall.
Water plans also differ. SpaceX says it has committed $220 million for Brownsville and Cameron County water and wastewater infrastructure, including $40 million it says it has already provided. The company says the projects could add about 20 million gallons per day from sources independent of the Rio Grande. The Arizona filing estimates 7 to 10 acre-feet of annual water use at full build-out, mainly for staff, and describes dry cooling without cooling towers. SpaceX has not stated the Texas computing facility’s own water use.
“Together, they represent more than $74 billion in planned American investment.”
— SpaceX, in its Nov. 12 announcement
Power, Water and Approvals Still Open
Neither project is assured to proceed as described. Both need local approval, and the scheduled Dec. 9 proceedings may not resolve every permit or utility question. The size of any Starbase property tax abatement is not stated in the source material, nor is the Texas facility’s computing capacity or its own water demand.
For Arizona, the county application sets out a proposed power route and a full-build electricity figure, but it remains unclear whether the utility and regulatory arrangements needed to deliver that power will be approved. SpaceX’s promise of lower bills for cooperative members depends on the electricity deal; its final terms and regulatory status are not provided. The company’s job, investment and water figures are proposed or estimated, and may change as the projects are reviewed.
There is also a distinction between the Arizona application and SpaceX’s announcement: Tombstone Resources L.L.C. filed the county paperwork, and the documents described in the source do not name SpaceX. SpaceX’s project page and Tombstone’s town-hall statement link the company to the proposal, but the application itself is not a direct filing under SpaceX’s name.
Dec. 9 Hearings Will Test Plans
On Dec. 9, 2026, the Cochise County Planning and Zoning Commission is scheduled to hold a hearing on the Arizona proposal. The Starbase City Commission is scheduled to consider a property tax abatement related to the Texas project. These proceedings are the next identified local milestones; the source material does not state that either meeting will grant final approval for every aspect of construction or operation.
Readers should watch for the outcome of the county review, any further utility or regulatory decisions affecting Arizona’s electricity supply, and additional city documents on the Texas tax request. Further filings may clarify construction timing, Texas generation capacity, site water use, and the conditions attached to local approvals. Until then, the announced investment totals describe planned projects, not completed construction or guaranteed spending.
