SpaceX has unveiled plans for two major supercomputing facilities that together represent more than USD 74 billion in planned American investment. The announcement, posted by the company, details a large-scale supercomputing campus at Starbase in the Rio Grande Valley of Texas and a second campus in Cochise County, Arizona.

Two New Campuses, One Mission

The company describes the projects as an extension of its existing work manufacturing rockets, spacecraft, satellite constellations, and spaceports, along with its recently announced USD 100 billion Terafab advanced chip manufacturing project in Grimes County, Texas, and its multibillion-dollar expansion of the Starlink production facility in Bastrop, Texas.

The company says it is now applying its hardware-building experience to constructing supercomputers through data centers. According to the company, the two facilities will train frontier intelligence systems intended to accelerate breakthroughs in medical research, emergency response, advanced manufacturing, and national security, while also helping develop and test technologies for the future of space-based computing.

Starbase Supercompute Facility Details

The Texas facility will be developed on SpaceX-owned property near the Port of Brownsville and the City of Brownsville landfill. SpaceX is planning to invest up to USD 24 billion in the project, which the company characterizes as one of the largest potential private investments in the history of the Rio Grande Valley. This new spending builds on the more than USD 15 billion SpaceX says it has already invested in Starship and related infrastructure at Starbase.

The project has already generated more than 3,000 construction jobs, with thousands more expected as development continues. Once operational, the facility is expected to support more than 500 permanent jobs.

A distinguishing feature of the Starbase facility is its energy plan: it will generate its own electricity rather than drawing power from the public grid. SpaceX says this design ensures the facility's energy demands do not compete with local homes and businesses or shift generation costs onto existing ratepayers.

Water Investment in the Rio Grande Valley

Alongside the compute campus, SpaceX has committed USD 220 million in private capital to expand water and wastewater infrastructure for Brownsville and Cameron County, which the company calls the largest private contribution to Brownsville's water future in the city's history. SpaceX has already provided USD 40 million to the Brownsville Public Utilities Board to get that work underway.

The investment addresses a regional challenge the company describes as urgent: roughly three-quarters of Brownsville's primary water supply comes from two Rio Grande reservoirs, both of which have faced critically low water levels. With drought conditions and growing demand placing increasing pressure on the region's water resources, expanding alternative supplies has become essential.

The Southmost Regional Water Authority has identified projects capable of adding approximately 20 million gallons of water per day from sources independent of the Rio Grande.

These include 8 million gallons per day through potable reuse of water Brownsville already treats, and 12 million gallons per day through expansion of the region's brackish-groundwater treatment capacity. According to the announcement, these projects had already been identified, and grant funding had been secured, but a roughly USD 220 million funding gap remained.

SpaceX says its USD 220 million commitment will help create 20 million gallons per day of additional water capacity, strengthen long-term water security, and avoid hundreds of millions of dollars in potential costs to local ratepayers.

Cochise County, Arizona Campus

The second project is a roughly USD 50 billion supercomputing campus in Cochise County, Arizona. The company expects the Arizona campus to create approximately 5,500 construction jobs and 1,000 permanent jobs.

The Arizona project takes a different approach to resources than the Texas site. Working with local electric cooperatives, the project aims to strengthen regional energy infrastructure and leverage existing renewable resources.

SpaceX says the effort could potentially reduce electricity bills for cooperative members by up to 20 percent. The campus will use dry cooling, with no planned industrial groundwater consumption.

Economic and Policy Considerations

SpaceX frames both projects as economic drivers that extend beyond the facilities themselves. The company says the investments will expand local tax bases, generate substantial new revenue for schools and public services, and create economic opportunities throughout the surrounding regions.

Together, the two campuses represent thousands of new jobs, new power and water projects, and what the company calls an opportunity to transform regional economies while advancing technologies that will benefit humanity.

The announcement also ties the projects' prospects to public policy. SpaceX states that realizing the full potential of the Starbase investment will require a stable, competitive, and supportive policy environment that allows projects of this scale to move forward.

More broadly, the company says these investments require strong partnerships with local communities, responsible environmental stewardship, and stable, competitive policies that give companies the confidence to make long-term investments.

Context Within SpaceX's Broader Buildout

The supercomputing announcement positions SpaceX as more than a launch provider. The company describes itself as building the infrastructure of the future and leading the world in manufacturing rockets, spacecraft, satellite constellations, and spaceports.

The Terafab chip project in Grimes County and the Starlink production expansion in Bastrop, announced previously, already signaled a shift toward advanced manufacturing at scale. The new compute campuses extend that trajectory into high-performance computing.

The company draws a direct line between its Texas history and its ambitions: SpaceX says it has helped make South Texas a center of American aerospace innovation, and now sees an opportunity to help make Texas and Arizona global leaders in supercomputing and super intelligence.

Community Commitments

SpaceX closes its announcement with a commitment to the regions hosting the new facilities. "We're ready to build," the company states, adding that it is committed to making sure the communities where it builds share in the benefits.

The USD 220 million water commitment in Brownsville, the off-grid power design at Starbase, and the dry-cooling approach in Arizona are presented as examples of that approach, alongside the job creation and infrastructure spending detailed across both projects.

The announcement does not specify construction timelines or operational start dates for either campus. It does, however, indicate that the Starbase project is already underway in at least one respect, with more than 3,000 construction jobs already generated and USD 40 million of the water investment already delivered to the Brownsville Public Utilities Board.
