SpaceX has outlined more than $74 billion in planned computing projects in Texas and Arizona, putting local land-use and tax decisions in focus as two hearings are scheduled for Dec. 9.
The company's Nov. 12 update puts the Arizona campus at about $50 billion, but its Texas cost descriptions conflict: one places the investment above $24 billion, while another sets an upper limit of $24 billion. A Starbase notice estimates about $24 billion for the Texas project's initial phases.
Starbase's notice describes a gas-fired power plant and computing facility on about 444 acres. SpaceX says the campus would generate electricity on site rather than draw from the public grid. The company said construction had created more than 3,000 jobs by Nov. 12 and forecast more than 500 permanent jobs once the facility is operating. It also said it had committed $220 million to water and wastewater infrastructure in Brownsville and Cameron County, with $40 million already provided.
In Cochise County, the application covers about 747 acres along U.S. Highway 191. County records identify Tombstone Resources LLC as the applicant on behalf of Arizona Electric Power Cooperative Inc. and Southline Transmission LLC. SpaceX has also announced an Arizona campus, but the county notice does not identify a formal relationship between SpaceX and Tombstone.
The county describes a proposal for up to nine computing buildings in four phases, with applicant-estimated electricity demand of six gigawatts at full buildout. Cochise County says it has not independently checked the submitted details and has made no decision on approval or regulatory compliance. SpaceX forecasts 5,500 construction jobs and 1,000 permanent positions in Arizona. The company says the site would use dry cooling without industrial groundwater use, and that cooperative members could see electricity bills fall by as much as 20%.
SpaceX's Super Intelligence segment became its largest by revenue in the third quarter, generating $7.56 billion of the $14.575 billion in total revenue for the quarter ended Sept. 30, according to its Form 10-Q. The filing says the segment was formerly known as AI.
The Cochise County Planning and Zoning Commission is scheduled to hear the Arizona application Dec. 9. Starbase's hearing that day concerns a proposed property-tax abatement and economic-development agreement for the Texas project.
