TL;DR
SpaceX announced plans for AI computing campuses near Starbase, Texas, and in Cochise County, Arizona, with more than $74 billion in planned investment combined. Local decisions are scheduled for Dec. 9, 2026; project details include a gas-fired Texas power plant and a large Arizona grid connection, while approvals and some resource and tax details remain unsettled.
SpaceX said Nov. 12 it is planning two large AI computing campuses in Texas and Arizona, describing the combined investment as more than $74 billion. The projects would pair a computing facility near the company’s Starbase launch site with a campus in Cochise County, but both still face local proceedings, and key details about power, water and public incentives have not been settled.
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 project as including a gas-fired power plant and gives an estimated initial capital investment of about $24 billion, with possible later expansion. 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.
SpaceX reports more than 3,000 construction jobs so far and says the Texas facility could support more than 500 permanent jobs when operating. It also says it has committed $220 million to water and wastewater infrastructure for Brownsville and Cameron County, including $40 million it says it has already provided. The company says related projects would add about 20 million gallons per day from sources independent of the Rio Grande. It has not disclosed the computing facility’s own water use.
In Arizona, SpaceX describes a campus costing roughly $50 billion, with up to nine computing buildings on about 747 acres near Cochise. The county application was filed by Tombstone Resources L.L.C.; the application materials cited in the source do not name SpaceX, while the company’s project page and Tombstone’s town hall statement connect the project to SpaceX. Plans call for as much as 6 gigawatts of grid power at full build-out and a 24-gigawatt-hour battery system. The application estimates annual water use of 7 to 10 acre-feet, mostly for staff, and about 1,000 employees at full build-out.
SpaceX’s AI Campuses Power, Water and Jobs
SpaceX has announced two proposed AI computing campuses in Texas and Arizona. Their investment, infrastructure and jobs could affect local communities, while approvals and some project details remain unsettled.
Two campuses, different power plans
The proposed sites would rely on different approaches to supplying electricity.
On-site generation
Near Starbase, the approximately 444-acre project includes a gas-fired power plant. SpaceX says it would generate its own electricity; the city notice gives no plant capacity.
Large grid connection
The proposed campus near Cochise covers about 747 acres and could include up to nine computing buildings, a 24-gigawatt-hour battery system and a large grid connection.
Local benefits and open questions
Jobs and infrastructure commitments are part of the proposals, but final plans and outcomes are not settled.
- SpaceX reports more than 3,000 construction jobs so far and projects more than 500 permanent jobs.
- The company says it committed $220 million to local water and wastewater infrastructure, including $40 million already provided.
- The computing facility’s own water use has not been disclosed.
- The application estimates about 1,000 employees at full build-out.
- Estimated annual water use is 7 to 10 acre-feet, mostly for staff.
- Power arrangements and proposed bill reductions still depend on approvals.
What happens next
Local proceedings are scheduled for the same day; neither campus is presented as fully approved.
The Planning and Zoning Commission is scheduled to hear the Arizona proposal on Dec. 9, 2026.
The Starbase City Commission is scheduled to consider a Texas property-tax abatement. Its size and terms are not specified.
Final designs, schedules, costs and utility arrangements remain subject to review and could change.
Power and Water at Campus Scale
The proposals show how the expansion of AI computing is becoming a question of local infrastructure and land use, not just technology investment. The Texas project would bring a gas-fired power plant to a site near SpaceX’s launch operations, while Arizona’s plan would depend on a very large grid connection. Those different approaches could shape local discussions about emissions, grid capacity, utility costs and reliability.
Jobs and public services are also part of the local stakes. SpaceX’s projected employment figures and water-infrastructure commitments are company statements, not guarantees of final outcomes. In Arizona, the project application’s estimated water demand is small relative to the agricultural comparison included in that filing, but the stated amount and assumptions should be judged against final plans and local review. The hearings will give residents and officials a venue to examine the projects before approvals are decided.

From Orbital Computing to Local Sites
SpaceX’s announcement follows its earlier public argument for computing infrastructure in space. After the company announced on Feb. 2 that it had acquired xAI, it said terrestrial AI electricity demand could impose hardship on communities and the environment, and pointed to data centers in orbit as an answer. The new plans put major computing campuses on the ground in two communities, although SpaceX presents the Texas site as also helping develop and test technologies for future space-based computing.
The projects are at different stages of documentation. Starbase’s notice outlines the Texas site and identifies a gas-fired plant, while a Cochise County land-use application provides specifications for the Arizona campus under the name Tombstone Resources L.L.C. SpaceX says the combined planned investment exceeds $74 billion. These are proposed investments, not completed facilities or final approved budgets.
“Together, they represent more than $74 billion in planned American investment.”
— SpaceX, in its Nov. 12 announcement
Approvals and Resource Details Pending
Neither campus is presented as fully approved. On Dec. 9, 2026, the Cochise County Planning and Zoning Commission is scheduled to hold a hearing, while the Starbase City Commission is set to consider a property-tax abatement. The size and terms of the Texas tax break are not specified in the source material, and the available details do not establish the outcome of either proceeding.
Several operating details also remain open. SpaceX has not provided the Texas computing facility’s capacity or its expected water use. A local news outlet, The 956 Report, said an air-registration filing submitted to the Texas Commission on Environmental Quality describes a temporary setup of 35 natural-gas turbines totaling about 748 megawatts, later to be replaced by eight larger turbines totaling about 708 megawatts. Those figures come from the outlet’s account of the filing, rather than the Starbase notice, which gives no capacity. In Arizona, the planned power arrangement and promised bill reductions for cooperative members still depend on approvals, including utility regulatory action whose status is not clear from the supplied material.
The construction and employment figures are projections or company-reported totals. Final project designs, schedules, costs and local conditions could change as applications are reviewed.
Dec. 9 Local Decisions Ahead
The next scheduled public steps are both set for Dec. 9, 2026: Cochise County’s Planning and Zoning Commission hearing on the Arizona proposal and the Starbase City Commission’s consideration of a Texas property-tax abatement. Their outcomes will clarify whether the projects can proceed under the requested local arrangements, but would not by themselves answer every question about construction timing or utility approvals.
Further details to watch include final permitting and power arrangements, the Texas campus’s computing capacity and water demand, and whether Arizona’s proposed electricity deal receives the required approval. Until those records and decisions are available, the investment, jobs and infrastructure figures should be treated as announced plans and estimates rather than completed results.
