SpaceX will spend more than $74 billion on two supercomputing campuses, splitting the bet between Starbase, Texas ($24 billion) and Cochise County, Arizona (about $50 billion). The company announced the plan on Thursday, in what ranks among the largest private compute commitments ever disclosed.

The scale is the story. These aren't launch pads or rocket factories — they're facilities built to train what SpaceX calls frontier intelligence systems, meaning AI models at the leading edge of capability. And in Texas, the company plans to generate its own electricity rather than pull from the public grid.

What does each campus actually involve?

The two projects differ sharply in size and staging.

• Arizona (Cochise County): roughly $50 billion in planned investment, with about 5,500 construction jobs expected and 1,000 ongoing roles once the campus operates.
• Texas (Starbase, near the Port of Brownsville): $24 billion in planned capital investment across initial phases. The project has already produced more than 3,000 construction jobs, SpaceX said, and should sustain over 500 permanent positions when running.
• Texas site footprint: an approximately 444-acre tract within Starbase city limits, on SpaceX-owned property.

The Texas campus will power itself. A City of Starbase public hearing notice showed SpaceX proposing to build, own and operate a natural gas power station alongside the supercomputing site — the mechanism behind the company's promise not to strain the local grid.

How is SpaceX handling water and power?

Big compute drinks water and burns power, and SpaceX arrived with numbers for both states.

In Texas, the company committed $220 million in private capital toward expanding water and sewage systems serving Brownsville and Cameron County. The work should add about 20 million gallons of water capacity per day. Of that commitment, $40 million has already gone to the Brownsville Public Utilities Board to start the work, according to SpaceX.

Arizona gets a different design. SpaceX said it is working with local electric cooperatives and aims to use existing renewable resources. The company claims the arrangement could cut electricity bills for cooperative members by up to 20%.

The Arizona campus will also use dry cooling — a method that dissipates heat through air rather than water — with no planned industrial groundwater consumption, SpaceX said. One open question remains: whether the site will also draw on gas power. Bloomberg reported that this is still uncertain.

The contrast matters. Texas means self-generation, gas included. Arizona means cooperative partnerships and renewables, with an explicit no-groundwater pledge. Two states, two infrastructure strategies.

What happens on December 9?

The Starbase City Commission will consider a property tax abatement agreement and a related economic development agreement for the project at its meeting at 7 p.m. CT on Dec. 9, per the hearing notice. That vote is the first formal gate the Texas project must clear.

An abatement is a deal in which a local government reduces a company's property taxes, usually in exchange for investment and jobs. It's the standard entry ticket for projects of this size — and a signal that SpaceX wants its tax terms locked before construction scales further.

Why is the Texas politics suddenly awkward?

The projects land in a shifting policy environment. Gov.-elect Gina Hinojosa, the first Democrat to win the Texas governorship since 1990, campaigned on a statewide moratorium on data centers. That's a direct threat to exactly this kind of development.

Her leverage is limited, though. Republicans hold the majority in the Texas Legislature, which constrains how much state policy she can actually change. The practical result: SpaceX faces a governor rhetorically opposed to its product, but a legislature likely unwilling to block it.

SpaceX addressed the tension without naming anyone. The company said investments of this scale require "stable, competitive policies" — a short sentence carrying a long message about regulatory risk.

What pushback has Arizona already produced?

Not everyone in Cochise County is sold. Hundreds of residents pressed SpaceX during a gathering the previous week, raising concerns about water use, electricity costs and local animals, according to The Next News.

The concerns map directly onto SpaceX's talking points. The company says no groundwater; residents worry about water. The company promises cheaper cooperative power; residents worry about electricity costs. The company pledges dry cooling; residents worry about local wildlife. The $50 billion question is whether the technical assurances close the political gap.

What's the strategic logic?

Add it up. More than $74 billion in announced capital. Roughly 8,500 construction jobs across both sites during the build. Around 1,500 permanent roles when both campuses run. A $220 million water infrastructure commitment in Texas, with $40 million already delivered.

The pattern is familiar to anyone tracking the AI infrastructure race: the largest players no longer buy compute, they build it — power plants, water systems, tax deals and all. SpaceX, which built its own rockets and its own launch sites, is now applying the same vertical logic to artificial intelligence.

The gamble rests on two things. First, execution: converting $74 billion of announcements into operating campuses. Second, politics: keeping Texas friendly under a skeptical incoming governor and keeping Arizona residents on side as construction begins. The Dec. 9 Starbase commission meeting offers the first concrete test.
