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.

This one hit my inbox and I had to read it twice. Anthropic announced a partnership with SpaceXAI for the entire Colossus 1 data center in Memphis. 220,000 NVIDIA GPUs. 300+ megawatts. That's the largest single compute acquisition by any AI lab. Full stop. But the part that ma...
SpaceX's S-1 surfaced that rival Anthropic rents 300MW (~220,000 GPUs) of xAI's Colossus 1 capacity near Memphis for $1.25B a month through May 2029, a contract that could exceed $40B, terminable on 90 days' notice. xAI posted a ~$2.4B Q1 loss against $7.7B capex. Competitors...
Reflection gets access to SpaceX's Colossus 2 data center near Memphis at $150M/month starting July 1, with immediate Nvidia GB300 access and a 90-day exit after the first three months. (CNBC) Reflection, last valued at $25B and building American open-source frontier models, j...
Two data points that tell the same story. First, Value Add Pulse counts four frontier launches in 30 days: Gemini 3.5 Pro, Grok 5, Anthropic's Fable 5 and Mythos 5, plus open-weight GLM-5.2 and Kimi K2.7. The model-layer moat compressed from quarters to weeks. Second, TechCrun...
Musk positioned it as trained on real Cursor sessions, landing fourth on the Artificial Analysis index, and Cursor's CEO called it a daily driver. But the top Hacker News thread centered on allegations Musk nudges outputs on political questions, while builders griped about "13...
SpaceXAI released Grok 4.5 on July 8, and for once the vendor hype and the third-party numbers point roughly the same direction. Musk called it "roughly comparable to Opus 4.7, but much faster." Priced at $2 per million input tokens and $6 per million output, that's over 60% b...
