SpaceX Plans $74 Billion in Supercomputing Campuses Across Arizona and Texas

SpaceX is advancing two massive supercomputing investments totaling roughly $74 billion, one in Cochise County, Arizona, and a second at its Starbase facility in the Rio Grande Valley of Texas. The Arizona campus, estimated at around $50 billion, would span approximately 700 acres in Cochise County, targeting up to six gigawatts of power capacity at full buildout across as many as nine computing buildings and is expected to create 6,500 jobs. The Texas project calls for more than $24 billion in new supercomputing infrastructure alongside a gas-fired power plant on roughly 444 acres near Brownsville, with SpaceX planning to construct, own, and operate both facilities.

The announcements were reported by Reuters and confirmed through a public hearing notice posted to the city of Starbase's website. The Arizona project has already drawn local opposition over its enormous infrastructure and power demands, and SPCX shares fell approximately 6% on the news as investors weighed the scale of capital required and regulatory uncertainties surrounding both developments.
