Anthropic is set to tap into Elon Musk's Colossus 1 supercomputer. Behind the surprise deal lie a compute crunch, a looming IPO, and a remarkable about-face by Musk.

Anthropic has also expressed interest in partnering up with SpaceX on the development of AI data centers in space.

Anthropic said it's forged a deal with SpaceX, which owns rival xAI, to use all of the compute capacity at the company’s Colossus 1 data center in Memphis, Tennessee.
