What happened. SpaceX said on Thursday 12 November 2026 that it plans to invest more than $74 billion in two AI supercomputing campuses: more than $24 billion at its Starbase site in Texas and about $50 billion in Cochise County, Arizona. The announcement, made under the company’s “Building the Future” initiative, was first reported by Reuters, citing a company statement, and confirmed in detail by The Wall Street Journal. It is one of the largest single capital commitments any company has made to AI compute this year.

The two sites. The Texas campus sits on SpaceX-owned property near the Port of Brownsville, close to its Starbase rocket site, and is designed to generate its own electricity rather than draw from the Texas grid. SpaceX says it will train frontier AI systems for medical research, emergency response, advanced manufacturing and national security, while supporting development and testing of future space-based computing. The company has committed $220 million to Brownsville-area water and wastewater infrastructure. The Arizona campus, in Cochise County near Willcox, would draw up to 6 gigawatts at full build-out — about ten times the capacity of the nearby Apache Generating Station — across nine single-story compute buildings of about 493,000 square feet each, built in four phases of about 1.5 gigawatts. SpaceX says the site would use dry cooling with no planned industrial groundwater use, and could cut cooperative members’ power bills by up to 20%. It estimates approximately 5,500 construction jobs at peak and 1,000 permanent positions.

What is still not decided. The money is promised, but the permission is not. Both sites face local decisions on the same day, 9 December. In Arizona, the Cochise County Planning and Zoning Commission will hear the special-use application for the campus, and a petition with about 2,400 signatures asks officials to deny the permit; the power deal still has to clear the state regulator. In Texas, the Starbase City Commission is due to consider a property-tax abatement. SpaceX has not disclosed accelerator suppliers, network architecture or commissioning schedules for either campus, and the $74 billion figure is the company’s own — none of it is contracted capacity or revenue. The Arizona plan runs in four phases with no dates past the first, and Texas’s $24 billion covers only the first phases.

Why SpaceX is doing this. The build-out has a substantial business base beyond rockets and Starlink satellite internet. Reuters reported that SpaceX’s AI segment generated more than half of the company’s third-quarter revenue, and quarterly revenue nearly doubled from $7.814 billion in the three months to 30 June 2026 to $14.575 billion in the quarter ended 30 September, according to filings with the US Securities and Exchange Commission. SpaceX is reported to have put roughly $48 billion into capital expenditure in the first nine months of 2026. The pattern is familiar across the industry: Anthropic has reportedly locked in $3.4 billion of gas generators for its own data centres, and Google has agreed to backstop Anthropic’s $19 billion Kentucky data centre lease. The compute race is now a power race, and SpaceX is buying its way in at a scale few companies can match — if the counties say yes.
