SpaceX Commits $74B to Twin AI Supercomputing Campuses in Arizona and Starbase, Texas

SpaceX publicly committed to more than $74B of US AI buildout, with $50B for a 9-building, 6 GW Cochise County campus in Arizona and $24B for the previously pitched Starbase supercomputing site in Texas; both face county votes on December 9. The move pairs with October disclosures that AI already drives more than half of SpaceX revenue and moves the Arizona project from preliminary reports to a formal commitment.
