SpaceX wants to build a $50 billion supercomputing campus in the Arizona desert, and the project is expected to create 6,500 jobs.

The company best known for landing rockets on barges is now proposing one of the largest US data center projects by power capacity. It would also be SpaceX’s first venture into gigawatt-scale, grid-connected AI computing.

What SpaceX is proposing

The project is called the Cochise Supercomputer Campus. It sits in Cochise County, Arizona.

The application did not arrive under the SpaceX name. An affiliate called Tombstone Resources LLC submitted a special use authorization application on October 30, 2026.

The plan covers 747 acres. It calls for up to nine buildings, each roughly 493,000 square feet.

The headline number is power. The campus has a peak capacity goal of 6 gigawatts (GW).

That capacity would not switch on all at once. SpaceX plans four development phases, each delivering approximately 1.5 GW.

The proposal also includes a 24 GWh battery storage system.

Then there is the grid itself. The plan includes $3.6 billion for grid upgrades meant to strengthen local electricity infrastructure.

Jobs, taxes and the town hall pitch

SpaceX made its case directly to residents at a town hall meeting on November 4, 2026.

Riley Trettel, head of energy and supercomputing development at SpaceX, confirmed the company’s role at that meeting. SpaceX would own the facility, build it and act as its long-term operator.

The project promises around 1,000 permanent jobs, plus thousands of construction roles during the build-out.

Beyond paychecks, SpaceX pitched the campus as a source of property tax income for the county.

The company also said the project could potentially reduce electricity bills for local cooperative customers.

The water question

SpaceX says the campus will use dry-cooling technology. Rather than evaporating large volumes of water to keep servers cool, dry cooling relies mostly on air to carry heat away.

The company projects water use of 7-10 acre-feet per year. It frames that as roughly the annual consumption of 20-30 homes.

The road to approval

The Cochise County Planning and Zoning Commission is scheduled to hold a public hearing on the project on December 9, 2026.

If the project clears that step, construction could begin as early as March 2027.
