Elon Musk's SpaceXAI to add another 660,000 AI GPUs this year, nearing a total of 1.44 million in operation

What happened

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 . This would bring SpaceXAI’s GB300 GPUs to 1.1 million units, with its total GPUs in operation to 1,440,000 units.

Colossus 1 is 150k H100, 50k H200 and 30k GB200. Colossus 2 is 110k GB200 and 440k GB300.

September 25, 2026 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 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.
