TL;DR
SpaceX announced plans for two large AI computing campuses: a facility near Brownsville, Texas, and a campus in Cochise County, Arizona. The company says the projects represent more than $74 billion in planned investment and would create construction and permanent jobs, but both require local approvals and several key details remain unresolved.
SpaceX announced Nov. 12 plans to build two large AI computing campuses, one in Starbase, Texas, and another in Cochise County, Arizona. The company says the projects represent more than $74 billion in planned investment and would add construction and permanent jobs, but each project still faces local approval steps.
SpaceX says it plans to invest more than $24 billion in a supercomputing facility on roughly 444 acres near the Port of Brownsville. A Starbase city notice describes the initial capital investment as about $24 billion and identifies a gas-fired power plant alongside the computing facility. SpaceX says the site will generate its own electricity rather than draw from the public grid; the city notice does not state the plant’s capacity.
The company says the Texas project has supported more than 3,000 construction jobs so far and could have over 500 permanent jobs when operating. Those figures are company estimates. SpaceX also says it has committed $220 million to water and wastewater infrastructure in Brownsville and Cameron County, including $40 million it says it has already provided. It has not disclosed the computing facility’s own water demand.
In Arizona, SpaceX describes a roughly $50 billion campus on about 747 acres near Cochise. The county application, filed by Tombstone Resources L.L.C., proposes as many as nine computing buildings, built in four phases. It estimates peak construction employment of about 5,500 workers, with roughly 250 staff when the first buildings open and about 1,000 at full build-out. The application describes up to 6 gigawatts of grid power at full capacity and a 24-gigawatt-hour battery system. The county documents do not name SpaceX; the company connection is supported by SpaceX’s project page and Tombstone Resources’ town hall statement.
SpaceX’s AI Campus Plans Put Jobs and Resources in View
SpaceX plans two AI computing campuses in Texas and Arizona, with major investment and jobs projected. Local approvals and key resource details remain unresolved.
Two campuses, different power plans
The proposed sites pair large computing facilities with distinct energy approaches.
- More than $24 billion planned near the Port of Brownsville
- On-site gas-fired power plant; capacity not stated in the city notice
- Over 500 permanent jobs projected
- Roughly $50 billion planned across four phases
- Grid power, local cooperatives and a utility-owned substation
- About 1,000 staff projected at full build-out
What the plans mean locally
Construction could bring jobs while adding demands on energy, infrastructure and public decision-making.
Temporary and lasting work
The estimates include thousands of construction roles and hundreds or more permanent positions, but hiring plans are not final.
Different energy systems
Texas proposes on-site generation; Arizona proposes grid supply with natural-gas generators for backup.
Demand still matters
Texas facility water use is undisclosed. Arizona estimates 7 to 10 acre-feet annually, mostly for staff.
Approvals shape the next steps
Both projects remain subject to local proceedings scheduled for Dec. 9, 2026.
The Planning and Zoning Commission is scheduled to hear the Arizona application.
The City Commission is scheduled to consider a property tax abatement tied to the Texas project.
Project size, schedule, staffing and resource demand may change as review proceeds.
Jobs, Power and Local Costs
The plans would bring large construction projects and long-term technical operations to two communities, while also requiring substantial energy infrastructure. SpaceX’s estimates point to thousands of temporary construction jobs and hundreds or more permanent positions, although the actual hiring pace and final staffing are not yet established.
The projects also raise distinct local questions. Texas would have an on-site gas-fired power plant, while the Arizona campus is planned to draw electricity through local cooperatives and a utility-owned substation. SpaceX says its Arizona cooling design will use dry cooling and that the facility will not use industrial groundwater. Those features could shape local debate over power supply, water use, air emissions and public costs.
For residents and local governments, the immediate issue is not just the investment headline but the terms of approval: how the projects affect services and infrastructure, what incentives may be offered, and whether the promised benefits match the eventual construction and operating plans.

From Orbital AI to Ground Sites
Earlier in 2026, after SpaceX announced it had acquired xAI, the company argued that growing AI electricity demand could not be met by terrestrial infrastructure without burdens on communities and the environment. Its proposed long-term answer included data centers in orbit. The new projects are on Earth, although SpaceX says the Texas site will also help develop and test technologies for future space-based computing.
The two applications describe different approaches. Starbase’s project is paired with an on-site gas power plant, while the Arizona proposal relies on the grid and local electric cooperatives, with natural-gas generators described as backup equipment. SpaceX’s public announcement and project page provide the company’s account; local notices and the Arizona application provide details about land use and proposed facilities. Those records do not make every project figure a final, approved commitment.
“Together, they represent more than $74 billion in planned American investment.”
— SpaceX, in its Nov. 12 announcement
Costs, Approvals and Resource Demand
Neither campus has received all the local approvals described in the source material. The Texas facility’s computing capacity, water consumption and tax-abatement terms remain unclear. A local news outlet, The 956 Report, reported details from a Texas air registration filing, including proposed turbine configurations and emissions limits; those reported figures are not given in the Starbase notice itself.
For Arizona, the application sets out a proposed build-out and estimates water use of about 7 to 10 acre-feet annually, mostly for staff. SpaceX says the campus would use dry cooling and that local cooperative members could see lower power bills, but it remains unclear whether the utility arrangements needed for those bill cuts will receive regulatory approval. The project’s final size, schedule, employment and electricity demand could change as review proceeds.
SpaceX’s combined investment figure and job estimates are plans and projections, not completed outcomes. The company has not provided a final construction schedule for both sites in the supplied material.
Dec. 9 Hearings Set the Course
Both projects face local proceedings on Dec. 9, 2026. The Cochise County Planning and Zoning Commission is scheduled to hold a hearing on the Arizona application. In Starbase, the City Commission is set to consider a property tax abatement related to the Texas project.
Those proceedings should clarify what local officials are being asked to approve and may bring additional information about project conditions, tax treatment and infrastructure. Arizona’s proposed electricity arrangements and the Texas facility’s power and water details remain material questions. Until approvals and further filings are available, the investment, jobs and resource figures should be treated as company plans or application estimates, not final operating outcomes.
