SpaceX Plans More Than $74 Billion in AI Supercomputing Campuses in Texas and Arizona

SpaceX is no longer just a rocket company that dabbles in AI. Its newest plan puts more money into computing than most companies are worth.

Space Exploration Technologies (NASDAQ: SPCX) said on Thursday, November 12th 2026, that it plans to invest more than $74 Billion USD in two AI supercomputing campuses, one at its Starbase headquarters in Texas and one in Cochise County, Arizona, according to Reuters. The company announced the plan on its own website, Bloomberg reported.

Roughly $50 Billion USD would go to Arizona and more than $24 Billion USD to Texas. Neither project is fully approved yet.

What happened

The Arizona campus is the bigger bet. SpaceX's project page describes nine supercompute buildings of about 493,000 square feet each, up to six gigawatts of power and up to 24 gigawatt-hours of battery storage. SpaceX says the site will be dry-cooled with no industrial water consumption, and that the computing will train its "super intelligence models."

The company told Reuters the Arizona site would create about 5,500 construction jobs and 1,000 permanent jobs, and that its work with local electric cooperatives could cut members' bills by up to 20%. A county filing described by SmartCR puts the first of four phases at about 1,500 megawatts, with power coming through the grid.

Texas takes a different path. The Starbase campus would sit on about 444 acres and generate its own electricity from a gas-fired power plant instead of drawing from the public grid, according to Reuters and Bloomberg. SpaceX expects more than 3,000 construction jobs and over 500 permanent ones there. It has also pledged $220 Million USD toward water and wastewater projects for Brownsville and Cameron County, The Hill and SmartCR reported.

Context: a rocket company that now earns most of its money from AI

SpaceX went public in June, and its AI segment generated more than half of its revenue in the third quarter, Reuters said. That's a remarkable shift for a company built on Falcon rockets and Starlink internet. These campuses are how SpaceX plans to keep that segment growing: more compute to train bigger models in-house.

Its scale also makes it a target. On the same day as the announcement, four nonprofits led by Public Citizen sued Anthropic, Google, Meta, OpenAI and two SpaceX Super Intelligence entities in San Francisco Superior Court, asking a judge to freeze the development of more advanced AI models, according to Public Citizen and Politico. It's a request, not a court order.

Why it matters

Six gigawatts is a utility-scale number. The real limit on AI today isn't only chips; it's power, land, water and local permission. SpaceX is trying to answer all four at once: its own gas plant in Texas, a dry-cooled design and lower power bills in Arizona, and hundreds of permanent jobs in both places.

Local approval is still the hurdle. A petition with 2,400 signatures asks Cochise County to deny the permit, Reuters reported, and the Starbase City Commission will consider a property tax abatement on December 9th. SmartCR reports proceedings in both places that day.

Investors shrugged. SpaceX shares closed Friday at $139.11 USD, down 0.59%, on a day when the Nasdaq fell 0.91% as AI stocks slid after Jensen Huang's exit from Nvidia, Reuters reported.

The money lesson

1. Follow the capital spending. A company tells you what it really believes by where it spends. Putting $74 Billion USD into compute says SpaceX sees AI as its main engine, not a side project.

2. Announced isn't approved. Big headline numbers often depend on permits, hearings and tax deals. Watch the December 9th votes before treating the full amount as certain.

3. Own the bottleneck. In Texas, SpaceX is building its own power instead of waiting in line for the grid. Controlling your scarcest input is one of the oldest advantages in business.

This is a story about where a company puts its money, which is what we covered in Episode 33 - Capital Allocation. In that episode, Kal compared it to Formula 1, where teams with bigger budgets can build their own wind tunnels and pull ahead faster. SpaceX is making the same kind of bet with data centers.

What to watch

  • Starship's 15th test flight. The launch window opens at 5:45 p.m. ET tonight, and SpaceX will try to catch both stages for the first time, GuruFocus reported via Yahoo Finance.
  • December 9th. Starbase's tax abatement vote and Cochise County's review will show whether both projects stay on schedule.
  • Power details. SpaceX hasn't disclosed the Texas plant's capacity or how much water the Texas site will use, SmartCR noted.
  • The frontier AI lawsuit. Any early ruling would matter for every lab spending on bigger models.

At the time of writing (about 5:00 PM ET on Nov 13, 2026), SpaceX shares had closed at $139.11 USD. This article is for informational purposes only and is not financial advice.
