SpaceX plans to invest over $74 billion to build two AI supercomputing campuses in the United States, according to a Reuters report. The projects will be located at Starbase in Texas and Cochise County in Arizona. The Starbase campus is expected to receive more than $24 billion in investment and will include dedicated power generation facilities. The Arizona project, with an estimated cost of approximately $50 billion, still requires local approval before construction can proceed.
