SpaceX intends to invest more than $74 billion in two artificial intelligence supercomputing campuses in the United States, one near its Starbase operations in Texas and another in Cochise County, Arizona. The plans expand the company’s computing infrastructure to support its growing artificial intelligence operations.

The Texas project carries an estimated cost of more than $24 billion and includes a gas-fired power plant that SpaceX would build, own and operate. The Arizona campus is projected at roughly $50 billion. Combined, the two developments form the full planned outlay of more than $74 billion.

Texas Campus Near Starbase

The Texas facility is planned on SpaceX-owned land in the Rio Grande Valley near Starbase. It will generate its own electricity rather than draw power from the public grid. A city notice described a gas-fired power plant and supercomputing complex on approximately 444 acres.

Construction activity has already generated more than 3,000 jobs at the site. Once operational, the project is expected to support more than 500 permanent positions. The Starbase City Commission is scheduled to consider a property tax abatement for the development on December 9.

SpaceX has described the Texas project as an opportunity for the South Texas region and noted investments in local water, wastewater and environmental work alongside the computing infrastructure.

Arizona Proposal in Cochise County

In Arizona, SpaceX affiliate Tombstone Resources LLC filed an application for special-use authorization covering 747 acres in Cochise County. The proposal calls for up to nine buildings, each measuring about 493,000 square feet. Development would advance in four phases, with each phase adding roughly 1.5 gigawatts toward a total capacity target of 6 gigawatts.

The plan incorporates a battery system with 24 gigawatt-hours of storage capacity and $3.6 billion in grid upgrades. SpaceX intends to use dry-cooling technology and projects annual water use of seven to 10 acre-feet, an amount comparable to the yearly consumption of 20 to 30 homes.

At a November 4 town hall, SpaceX’s head of energy and supercomputing development, Riley Trettel, told residents the company would build, own and operate the site. If completed, the campus would mark SpaceX’s first grid-connected AI computing facility at gigawatt scale.

The project is projected to create about 5,500 to 6,500 jobs in total, including roughly 1,000 permanent positions and several thousand construction roles. SpaceX has stated the development could generate property-tax revenue for the county and potentially reduce electricity bills for members of local cooperatives by as much as 20 percent.

The Cochise County Planning and Zoning Commission has scheduled a public hearing for December 9. If the proposal advances, construction could begin as early as March 2027.

Investment and Timeline Overview

SpaceX has framed both projects as steps to strengthen its artificial intelligence business. The company’s AI operations accounted for more than half of its revenue in the most recent reported quarter. The facilities remain proposals subject to local approvals and further development decisions.

The two sites are separate developments. The Texas campus pairs computing capacity with dedicated on-site power generation, while the Arizona project focuses on a large-scale computing campus connected to the regional grid with supporting infrastructure upgrades.
