OpenAI cuts Cursor access after SpaceX deal

In a major industry shift, OpenAI has announced it will terminate its partnership with the AI coding tool Cursor by November 2026. This decision follows the $60 billion acquisition of Cursor by SpaceX, a move that triggered a change-of-control clause and raised concerns at OpenAI regarding Elon Musk's history of contract adherence. While OpenAI intends to stop providing its models to the platform, Cursor leadership noted that these models currently represent only a small fraction of their total user traffic. In response to the friction between the rival billionaires, Anthropic has stepped in to deepen its collaboration with Cursor by offering increased compute resources and model support. This corporate fallout highlights the growing volatility of API dependencies and the strategic importance of controlling distribution channels within the developer ecosystem. Experts suggest that the move may accelerate the adoption of Grok or other alternative models as developers navigate the ongoing feud between tech giants.
