Elon Musk‘s xAI has filed roughly $300 million in permit applications for its Colossus I and Colossus II campuses, with permits filed between June 22 and June 26, plus an additional filing in May. For Colossus I, xAI plans to spend approximately $301 million in planned expansion work, including an alteration project valued at nearly $250 million for light manufacturing and a separate permit listing about $50 million for warehouse and distribution. For Colossus II, filings indicate roughly $250 million in expansion work tied to "Phase III." The filings come as xAI faces an ongoing lawsuit from the NAACP, which accuses xAI of breaking federal air-pollution rules, alleging dozens of methane-fueled generators were run without required permits. Additionally, xAI pulled back an electrical permit submitted on June 15 for Colossus II. The Memphis and Shelby County Division of Planning and Development have granted two electrical permits for office space at Colossus II. City records also list two permit applications to remove "30 fixtures" related to plumbing at Colossus II, with one approved and work estimated at $300,000. Records indicate xAI is set to restart construction on a greywater recycling facility near Colossus II. In May, Tennessee lawmakers passed HB1847, requiring data center owners to pay for the full cost of supporting infrastructure.
