Musk's Anthropic Deal Turns Idle xAI Compute Into Cash

Elon Musk has cut a surprise deal with Anthropic that solves problems on both sides of the table. Anthropic gets relief from a severe compute deficit. Musk gets to monetize idle capacity from xAI's Colossus 1 cluster, which Grok never grew large enough to fully utilize.

The arrangement is being described as an "Anthropic-SpaceX deal," though the unused compute at the center of it traces back to xAI's infrastructure. For Musk, it's a two-birds-one-stone play — generating revenue from dormant resources while the backdrop of his ongoing OpenAI lawsuit adds an extra layer of strategic intrigue.

Anthropic has been scrambling for compute as demand for its Claude models surges. Tapping surplus capacity from a rival's ecosystem is an unconventional but pragmatic move to close the gap.
