xAI Leases Entire Colossus 1 Supercomputer to Anthropic — Rivals Turn Partners as Musk Flips From 'Hates Western Civilization' to 'Impressed'

TechCrunch·high signal

xAI signed an agreement giving Anthropic access to Colossus 1's 220,000 GPUs and 300MW+ capacity in Memphis. This is striking given Musk's February post that Anthropic 'hates Western civilization' — he now says he spent a week with senior Anthropic staff and was 'impressed.' TechCrunch and SpaceX framing suggest this is also a strategic play: Anthropic has 'expressed interest' in partnering with SpaceX on multi-gigawatt orbital AI compute.
