TL;DR
SpaceX says it plans to invest more than $74 billion in two AI computing projects: a facility with its own gas-fired power plant near Starbase, Texas, and a grid-powered campus in Cochise County, Arizona. Both proposals face local decisions on Dec. 9, 2026; their scale, energy arrangements and potential local impacts differ, and some details remain unsettled.
SpaceX said Nov. 12 it is advancing two large AI-computing projects, one near its Starbase launch site in Texas and another in Cochise County, Arizona, describing the combined plans as more than $74 billion in investment. Both projects face local proceedings on Dec. 9, 2026, but they are not yet approved: the Texas city commission is due to consider a property-tax abatement, while an Arizona county planning commission is scheduled to hear the campus application.
In Texas, SpaceX says it plans to invest more than $24 billion in computing infrastructure on an approximately 444-acre site between Boca Chica Boulevard and the Port of Brownsville. A Starbase city notice describes the initial phases as an approximately $24 billion project 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 generating capacity or the computing facility’s capacity.
SpaceX says the Texas project is intended to train AI systems and support work in fields including medical research, emergency response and manufacturing. The company reports more than 3,000 construction jobs so far and says the facility could have more than 500 permanent jobs once operating. Those figures are company statements, not independently confirmed employment totals. SpaceX also says it has committed $220 million to water and wastewater infrastructure in Brownsville and Cameron County, including $40 million it says has already been provided. It has not disclosed the computing site’s own water use.
The Arizona proposal is a roughly $50 billion campus on about 747 acres near Cochise, with up to nine computing buildings and a planned full-build power demand of about 6 gigawatts. The county application was filed by Tombstone Resources L.L.C.; the documents reviewed do not name SpaceX, though SpaceX identifies the project on its own website and Tombstone’s town-hall statement says SpaceX would host a community meeting. The application describes power delivered through local electric cooperatives, dry cooling, and estimated water use of 7 to 10 acre-feet per year at full build-out, mostly for staff. It also estimates about 5,500 construction workers at peak and up to 1,000 ongoing staff at full build-out.
SpaceX’s AI Campus Plans Texas and Arizona
SpaceX says it plans more than $74 billion in AI computing projects across two states. Local decisions are scheduled for Dec. 9, 2026, and both proposals remain subject to approval.
Two sites, different power plans
The energy arrangements shape the questions residents and officials will weigh.
- More than $24 billion planned for computing infrastructure.
- Gas-fired plant intended to generate electricity on site.
- Plant capacity and the facility’s water use are not stated in the city notice.
- Roughly $50 billion planned across about 747 acres.
- Grid power through local electric cooperatives.
- Application estimates 7 to 10 acre-feet of annual water use at full build-out.
Local impacts are still projections
Jobs and infrastructure commitments may matter to communities, but announced figures are not verified outcomes.
Jobs and water systems
SpaceX reports more than 3,000 construction jobs so far and says over 500 permanent jobs are possible. It says $220 million is committed to regional water and wastewater infrastructure.
Staffing at full build-out
The application estimates about 5,500 peak construction workers and up to 1,000 ongoing staff.
What happens next
The proceedings address different local decisions.
The city commission is due to consider a property-tax abatement; its size and terms remain unclear.
The planning and zoning commission is scheduled to hear the campus proposal.
Two Regions, Different Power Demands
The proposals would make local decisions about land use, electricity, infrastructure and public finances part of a much larger debate over where the energy-intensive computing behind AI will be built. The stated investments are substantial, but the projects’ local effects depend on approvals, construction schedules and final operating plans—not only on headline dollar figures.
The two power plans carry distinct questions for residents and officials. SpaceX says the Texas site will produce its own electricity with a gas-fired plant, while the Arizona project would draw power from the grid through electric cooperatives. The Arizona application’s 6-gigawatt full-build estimate signals a major planned demand on the electricity system, but it does not by itself establish how much power will be available or when. For Texas, the city notice confirms a gas plant but does not specify its capacity. Those differences matter for evaluating infrastructure requirements and potential community effects.
There are also local economic and fiscal stakes. SpaceX has described construction and permanent jobs in both states, and its Texas proposal includes investment in regional water and wastewater systems. In Starbase, the pending tax-abatement discussion will determine whether the city considers a public incentive for the project. In Arizona, the county process will test the site proposal and associated plans. The company’s investment and jobs figures are projections or claims; the eventual benefits and costs are not yet established.

From Orbital AI to Ground Sites
SpaceX’s new plans follow its earlier public argument for computing in space. After announcing its acquisition of xAI on Feb. 2, the company said demand for AI electricity could not be met by terrestrial infrastructure without hardship to communities and the environment, and presented orbital data centers as an answer. The November announcement instead puts two large computing projects on the ground in Texas and Arizona. SpaceX says the Texas facility will also help develop and test technologies for future space-based computing.
The announcement’s headline investment figure combines different kinds of projects and stages. SpaceX describes Texas as an investment of more than $24 billion and Arizona as roughly $50 billion, while the Starbase notice calls the Texas amount an estimate for initial phases and refers to possible later expansion. These are planned investments, not completed spending. The Arizona county filing uses Tombstone Resources L.L.C. as applicant, and the county documents themselves do not identify SpaceX; the project connection is supplied by SpaceX’s project page and Tombstone’s statement.
The source documents also vary in detail. The Arizona application provides estimates for building size, power, water and staffing. In Texas, the city notice confirms a gas-fired plant but does not list its capacity. Local outlet The 956 Report, citing an air registration submitted to the Texas Commission on Environmental Quality, reported plans for a temporary arrangement of 35 natural-gas turbines totaling about 748 megawatts, followed by eight larger turbines totaling about 708 megawatts. Those figures come from the outlet’s account of the filing, rather than the Starbase notice itself.
“Together, they represent more than $74 billion in planned American investment.”

Capacity, Incentives and Approvals
Neither project has received all the local decisions identified in the source material. In Texas, the size and terms of any tax abatement remain unclear, as do the computing facility’s capacity and its own water demand. The city notice does not provide the gas plant’s capacity. Additional turbine figures have been reported by The 956 Report based on an air registration, but they are not detailed in the cited city notice.
In Arizona, the application lays out a proposed grid connection and forecasts up to 6 gigawatts of demand at full build-out. It remains unclear whether the electricity arrangements will receive all required approvals, including any necessary utility-regulatory decisions, and whether the project will proceed at the proposed scale or schedule. SpaceX has promised lower bills for members of the local electric cooperative, but the mechanics and approval status of that arrangement are not established in the material provided.
Across both states, announced investment, jobs, power use and water figures describe plans or estimates, not verified operating outcomes. The schedule for construction, the final facilities and the practical effects on nearby communities have not been established.
Dec. 9 Local Decisions
On Dec. 9, 2026, the Cochise County Planning and Zoning Commission is scheduled to hold a hearing on the Arizona proposal. On the same day, the Starbase City Commission is due to consider a property-tax abatement related to the Texas project. These are the next specified local proceedings; the source material does not state that either one alone would settle every permit, utility or financing question.
Residents and officials will be looking for more detail on project approvals and implementation. In Texas, that includes the proposed tax terms, power-plant capacity and site water use. In Arizona, key questions include the final scope, the grid-supply arrangements and the promised effect on cooperative members’ bills. Further filings and decisions will show whether the announced plans advance as described.
