OpenAI Cuts Off Cursor Because SpaceX Bought It

OpenAI Cuts Off Cursor Because SpaceX Bought It OpenAI announced it is ending Cursor's direct model access on November 12 following Cursor's acquisition by SpaceX — a termination triggered by a change in who owns the customer rather than by anything the customer did. That turns access to a frontier lab's models into a governance dependency with a live precedent behind it. In the same cycle, the hedges against that dependency were being funded and shipped: Mistral published a European sovereignty roadmap and signed an infrastructure and model deal with Saudi state AI company HUMAIN, and Tencent released a 770-billion-parameter open-weight model. The episode also covers compute scarcity reaching the customer tier — Anthropic's Claude Code limit change that reads as a 25% increase but nets out below current levels, Google's half-price Gemini 3.7 Flash, and a16z's infrastructure fund — plus the Sony Music and Warner Chappell copyright suit against Anthropic, the $39 billion spread between outlets counting Big Tech's paper gains on AI stakes, Texas freezing Flock camera funding, and the MIT EEG study landing alongside Claude's K-12 rollout.
