STARBASE, Texas: Elon Musk's SpaceX is betting more than $74 billion on two supercomputing campuses in Texas and Arizona, deepening a push into artificial intelligence that already accounts for more than half of the company's revenue.

SpaceX expects to spend roughly $50 billion on a campus in Cochise County, Arizona, and more than $24 billion at its Starbase site in Texas, the company said in a statement on November 12. The plans expand its AI computing ambitions alongside its rocket and satellite businesses.

The AI segment of the company, which went public in June, generated more than half of its revenue in the third quarter, highlighting how far the business has moved beyond rockets and Starlink satellite internet.

The Arizona campus, which needs approval from Cochise County, would create about 5,500 construction jobs and 1,000 permanent jobs.

SpaceX said it was working with local electric cooperatives and the project could cut bills for cooperative members by up to 20%. It said the campus would use dry cooling, with no planned industrial groundwater use.

The facility, however, faces some opposition. A petition with 2,400 signatures has asked officials to deny the permit, and a county public hearing is set for December.

In Texas, the Starbase facility would generate its own electricity rather than draw from the public grid. A city notice earlier this week showed plans for a gas-fired power plant and supercomputing facility on about 444 acres.

SpaceX said the Texas project had generated more than 3,000 construction jobs and would support more than 500 permanent jobs once operational.

The Starbase City Commission is due to consider a property tax abatement for the project on December 9.
