Elon Musk’s SpaceXAI to add another 660,000 AI GPUs this year, nearing a total of 1.44 million in operation — firm is building 1.2-gigawatt power plant to bring systems fully online

The end goal is finally in sight for Elon Musk, nearly two years after he announced plans to expand the Colossus supercomputer to over a million GPUs. The billionaire said on X that 220,000 Nvidia GB300 GPUs will be operational by next week, with another 220,000 coming online in November. He also added that another 220,000 units will come online by late December “if we get lucky.”

These numbers would add to the 110,000 GB200 and 440,000 GB300 GPUs already operating at Colossus 2, plus the 150,000 H100, 50,000 H200, and 30,000 GB200 GPUs at Colossus 1. This would bring SpaceXAI’s GB300 GPUs to 1.1 million units, with its total GPUs in operation to 1,440,000 units. This is quite an achievement, especially given that the company is behind its rivals by several years — SpaceXAI is only three years old, while Anthropic and OpenAI are six and ten years old, respectively. Interestingly, the Colossus 1 site, which features a combination of Hopper and Blackwell GPUs, is inefficient for training Grok, so Musk rented it out to Anthropic for inference instead. On the other hand, Colossus 2 solely uses Blackwell GPUs, ensuring that there won’t be any bottlenecks.
