SpaceXAI plans to switch on about 420,000 Nvidia GPUs in November, report says
In brief
- SpaceXAI plans to activate about 420,000 Nvidia GPUs in November, per Crypto Briefing.
- Colossus 1 and 2 house about 780,000 Nvidia GPUs, Musk said on September 25.
- Musk plans 660,000 more GPUs by year-end, for a fleet of roughly 1.44 million.
- Anthropic leases more than 220,000 Colossus 1 GPUs, according to the report.
- The Anthropic lease could be worth up to $84.5 billion by 2029, a ceiling, not cash received.
What's running at Colossus today
On September 25, 2026, Musk laid out the hardware breakdown across the two Colossus sites, as reported by Crypto Briefing. Colossus 1 runs three Nvidia generations: 150,000 H100 chips, 50,000 H200 chips and 30,000 GB200 chips, for 230,000 GPUs in total. Colossus 2 holds 110,000 GB200 chips and 440,000 GB300 chips, or 550,000 in total. (The Colossus 2 figures reportedly reflect capacity limits tied to networking constraints.)
Put together, that's roughly 780,000 Nvidia GPUs.
The year-end target
Musk also announced plans to bring 660,000 additional GPUs online by year-end. If that happens, the fleet would reach approximately 1.44 million. Crypto Briefing places the roughly 420,000 GPUs scheduled for November inside that year-end timeline.
The hardware is meant to support training and inference for Grok, the company's family of AI models (including Grok 4.7). SpaceXAI is also building a 1.2-gigawatt power plant to support the expanded cluster, according to the report. It doesn't stop there. Musk's 2030 goal is infrastructure equivalent to 50 million H100-class GPUs, and he's consistently stressed close partnerships with Nvidia.
Renting compute to Anthropic
Not all of that capacity is going to Grok. SpaceXAI has leased more than 220,000 GPUs from Colossus 1 to Anthropic, Crypto Briefing reported, and the arrangement could be worth up to $84.5 billion by 2029.
That number deserves some care. It's a potential ceiling tied to future commitments, not cash SpaceXAI has already collected, so the actual value will depend on how those commitments play out. The outlet framed the deal as SpaceXAI renting out horsepower to a direct competitor in the model race, while it keeps scaling its own fleet.
For anyone tracking the AI infrastructure buildout, the November activation is the next concrete checkpoint against Musk's year-end target.
Frequently asked questions
How many GPUs does SpaceXAI run at Colossus?
Musk said on September 25, 2026 that Colossus 1 runs 230,000 Nvidia GPUs and Colossus 2 holds 550,000, as reported by Crypto Briefing. That's approximately 780,000 Nvidia GPUs across the two facilities.
How big is SpaceXAI's GPU expansion planned for this year?
Musk announced plans to bring 660,000 additional GPUs online by year-end, which would take the fleet to approximately 1.44 million. Crypto Briefing reported that about 420,000 of those are scheduled for November.
What is SpaceXAI's GPU lease with Anthropic worth?
Crypto Briefing reported that SpaceXAI has leased more than 220,000 Colossus 1 GPUs to Anthropic. The arrangement could be worth up to $84.5 billion by 2029, but that's a potential ceiling tied to future commitments, not cash already collected.
