SpaceX plans $74 billion of AI supercomputer campuses in Texas and Arizona

SpaceX said on Nov. 12, 2026, it plans to invest more than $74 billion in two supercomputing campuses, one at its Starbase site in Texas and one in Cochise County, Arizona.

A rocket company that now makes most of its money from AI just put a $74 billion price tag on proving it. The interesting fine print is power: Texas brings its own gas plant, Arizona promises cheaper co-op bills and no groundwater, both answers to the two things local opposition to data centers usually fights over. The Cochise County hearing in December is the first real test of whether that pitch works.

SpaceX said on Thursday, Nov. 12, 2026, that it plans to invest more than $74 billion in two supercomputing campuses. The opening of its own update says more than $24 billion for new supercomputing infrastructure at Starbase, in the Rio Grande Valley of Texas, and roughly $50 billion for a campus in Cochise County, Arizona. A later section of the same update says the company is planning to invest up to $24 billion in the Texas project alone. Reuters reported the Texas figure as more than $24 billion. A supercomputing campus, here, is a set of buildings full of the chips that train and run AI models. Those investment lines are SpaceX's, in the Nov. 12 update. Reuters, Quartz, and Channel News Asia carried the announcement the same day.

The AI segment of the company generated more than half of SpaceX's revenue in the third quarter, Reuters reported. SpaceX went public in June 2026. Those two lines are Reuters's. The update does not print a revenue figure.

The Arizona campus needs approval from Cochise County. SpaceX says it would mean about 5,500 construction jobs and 1,000 permanent jobs. The company says it is working with local electric cooperatives, the member-owned utilities that serve the area, and that the project could cut those members' bills by up to 20 percent. The campus would use dry cooling, with no planned industrial groundwater use. Dry cooling means the machines are cooled with air, rather than by drawing water out of the ground. Those lines are SpaceX's. A petition with 2,400 signatures has asked officials to deny the permit, and a county public hearing is set for December. That opposition is Reuters's account.

The Starbase facility would generate its own electricity rather than draw from the public grid. That line is SpaceX's. A city notice this week showed plans for a gas-fired power plant and a supercomputing facility on about 444 acres, Reuters reported. Quartz, reading the same notice, described a natural gas power station on an approximately 444-acre tract, and said the Starbase City Commission will consider a property tax abatement at 7 p.m. Central time on Dec. 9. A property tax abatement is a deal that cuts the tax a company pays on a site for a set period. SpaceX's update says Brownsville transferred about 444 acres near the port and the city landfill to the City of Starbase, and that the company is working with Starbase and Cameron County on tax agreements. SpaceX says the Texas project has already generated more than 3,000 construction jobs and would support more than 500 permanent jobs once it is running. Those job counts are SpaceX's.

In plain terms, SpaceX put a price of more than $74 billion on two AI computing campuses, one beside its Texas rocket site and one in rural Arizona that still needs a county permit. The company says Texas will bring its own power and Arizona will not use groundwater for industry. A petition and a December hearing are the first public test in Cochise County. A Starbase commission meeting on Dec. 9 is the Texas one.
