On July 9, Musk called Anthropic "obviously currently the leader in AI" and pledged never to cut off access, reversing his September 2025 claim that "winning was never in the set of possible outcomes for Anthropic." The context is structural: Anthropic pays roughly $1.25B/month through May 2029, about $40B total, for the entire 300MW output of xAI's Colossus 1 near Memphis. Days after xAI shipped Grok 4.5 as a direct Opus-class competitor. If you build on hosted frontier models, ask yourself whether a verbal assurance from a direct competitor is a supply-chain guarantee you'd plan around.
