OpenAI models turn out to be about 5 percent of Cursor's traffic

After OpenAI announced it would end Cursor's model access on a proposed date of November 12, 2026, Cursor CEO Michael Truell said OpenAI models account for about 5 percent of Cursor's AI traffic. OpenAI cited Elon Musk's history of breaking contracts, including ending Twitter's data-sharing deal with OpenAI and allegedly training Grok on other labs' model outputs. Musk responded that he could not care less. Anthropic co-founder Tom Brown called Cursor a trusted partner since Sonnet 3.5 and pledged to keep expanding Claude compute for Cursor.

OpenAI will cut off Cursor's model access on November 12

OpenAI said on August 28, 2026 that it will end the deal giving Cursor direct access to its models, with a proposed shutoff on November 12. The reason is not Cursor itself but SpaceX, which acquired the coding tool: OpenAI says it cannot be confident SpaceX will stay within its terms of service, citing past violations by Musk-owned companies. Cursor CEO Michael Truell said OpenAI models are only about 5 percent of Cursor's traffic and that the two teams are still talking.

SpaceX closed its $60 billion purchase of Cursor maker Anysphere

SpaceX completed its $60 billion acquisition of Anysphere, the company behind AI code editor Cursor, on August 14, 2026. The all-stock deal converted Cursor's shares into roughly 389 million SpaceX shares, with Cursor becoming a wholly owned unit of the new SpaceXAI division. Both companies say no startup has ever been bought for more. Cursor gains access to the 200,000-GPU Colossus supercomputer and its team will also work on Grok products including Grok Build, Grok Bot and the Grok API.
