Notes on the xAI/Anthropic data center deal

simonwillison.net·May 7, 2026

Anthropic has announced a deal to utilize SpaceX/xAI's Colossus data center, despite its poor environmental reputation, raising concerns about the implications of this partnership amid ongoing debates over AI data centers' impact. The announcement comes as xAI phases out certain models, leading to frustration among users who relied on their services.

The recent Anthropic deal with SpaceX/xAI to utilize the Colossus data center highlights a significant compute capacity expansion for Anthropic, but also introduces potential supply chain risks due to environmental issues and Elon Musk's stated criteria for reclaiming compute based on AI's impact on humanity. This development could affect AI workflow strategies and considerations for ethical AI implementations.
