Elon Musk disclosed on X that SpaceX’s Colossus 2 data center currently holds 110,000 GB200 and 440,000 GB300 chips, with plans to add 220,000 GB300 units next week, another 220,000 in November, and possibly a further 220,000 by late December. If those additions happen, total capacity would rise from 550,000 to 1.21 million chips. The article notes SpaceX has rented GPU capacity to Anthropic and Alphabet at a premium, and the extra capacity could be rented out or used for Grok.

Musk shared the figures in a Friday reply on X, describing Colossus 2’s present inventory as 110,000 GB200 units and 440,000 GB300 units. He said 220,000 more GB300 chips should be fully running the following week, with another 220,000 due in November and a possible final 220,000 by late December. That would lift the site from 550,000 chips to 1.21 million, though the two chip types differ in compute output. The 110,000 increments reportedly stem from how many fiber cables a central switch can accept.

SpaceX has already rented GPU capacity from Colossus 1 to Anthropic and Alphabet, according to the article, and one analyst said such buyers paid roughly triple the usual rate to secure 200,000 GPUs quickly. The term for this business is a “neocloud.” Additional capacity could serve Grok or outside renters, and rental income may help fund further expansion.
