Musk claims around 1.2 million Blackwell GPUs at Colossus 2 by year-end
From the AI digest for Oct 31, 2026
What happened: Elon Musk put first figures on the Colossus 2 buildout in reply posts. Responding to a NextBigFuture post, he writes "Macrohard is 110k GB200 and 220k GB300." In a walk-through post on the whole Colossus 2 site, he itemizes the buildings: "Macroharder" and "Minihard" carry 220,000 GB300s each with 800-gig networking configured for training; "Gun Range," which he says in a follow-up was literally the local police department's gun range that was bought, is to carry the same 220,000 GB300s and is "tracking to be operational by end of November"; "Spam," in a building he says used to house Hormel products, is to carry about 200,000 GB300s configured for inference and land in December. He credits progress to the SpaceX team and contractors. A separate post claims "there will be a total of around 1.2M Blackwells at Colossus 2 by end of year."
What's genuinely new: The first per-building GPU counts and dates for the Colossus 2 campus — a ~1.2 million Blackwell total by year-end, a building due operational by the end of November and another in December — all self-reported from Musk's own walk-through, with no independent count yet of what the site actually holds.
Watch: Whether Gun Range actually goes operational by the end of November and Spam in December, whether the 1.2 million Blackwell total checks out against any independent or press count, and how the per-building figures compare with what xAI discloses through official channels.
