TLDR: MEMPHIS, Tenn.—xAI will sell Anthropic $1.5 billion monthly compute from Colossus 1 in Memphis, totaling over $40 billion through May 2029. Anthropic gets 300 megawatts; xAI gains a major revenue stream tied to Grok demand risk.
Key Takeaways:
- xAI, tied to SpaceX, lines up massive compute contracts as LLM demand shifts and hardware sits underused.
- Anthropic will pay $1.5 billion each month for Colossus 1’s full 300 megawatts through May 2029 under a deal reported from an SEC filing.
- Either side can cancel with 90 days notice, so xAI revenue depends on Anthropic still wanting that capacity.
The AI arms race runs on megawatts, not demos. xAI is monetizing idle hardware by outsourcing it to the one rival that can pay.

Q&A
What happens to xAI’s bargaining power if Anthropic scales down inference demand before May 2029?
xAI could face pricing pressure or early renegotiation, especially because the contract can be canceled with 90 days notice.
Why does selling compute to a competitor help xAI look stronger than admitting Grok is under demand?
Revenue and utilization tell a more reassuring story to markets than internal forecasts, particularly around major fundraising or listing moments.
How could contract cancellation risk affect how both companies plan new model launches?
They may stagger release timelines, diversify compute sources, or lock alternative capacity to avoid sudden supply gaps.
What does a 300 megawatt commitment suggest about the real bottleneck in today’s AI race?
It points to power and data center throughput as limiting factors, not just model research talent.
Could pressure over data center impacts influence future compute contracts, even if the math still works?
Yes, reputational and regulatory scrutiny can tighten permitting and operating timelines, which can reshape which providers remain acceptable long term.
