SpaceXAI plans to switch on about 420,000 Nvidia GPUs in November

SpaceXAI plans to activate about 420,000 Nvidia GPUs in November, all aimed at meeting fresh compute commitments. The November ramp is part of a broader push at Colossus, the supercomputer cluster in Memphis, Tennessee, that powers Elon Musk’s AI ambitions. It also arrives as the company starts renting out some of that horsepower to Anthropic, a direct rival in the model race. What is actually inside Colossus On September 25, 2026, Musk laid out the current hardware breakdown across the two Colossus sites. Colossus 1 runs a blend of three Nvidia generations: 150,000 H100 chips, 50,000 H200 chips and 30,000 GB200 chips. Add those up and you get 230,000 GPUs. Colossus 2 is newer and much larger. It holds 110,000 GB200 chips and 440,000 GB300 chips, for 550,000 in total. Combined, the two facilities house approximately 780,000 Nvidia GPUs. The Colossus 2 figures reportedly reflect capacity limits tied to networking constraints. The road to 1.44 million Musk also announced plans to bring 660,000 additional GPUs online by year-end. If that happens, the total fleet would reach approximately 1.44 million. The roughly 420,000 GPUs slated for November sit within that aggressive year-end tim...
