OpenAI Ends Cursor Model Deal by Nov. 12, 2026 as SpaceX Acquisition Triggers Compliance Fears

Summary
November 12, 2026 is OpenAI’s proposed shutoff date for Cursor’s access to its models after it notified SpaceX it will wind down the contract.
SpaceX’s acquisition of Cursor opened a limited contractual window to cancel, and OpenAI said it no longer trusts Musk-controlled companies to follow its terms of service.
OpenAI cited past breaches after Musk bought Twitter and testimony this year in which Musk acknowledged xAI had violated OpenAI’s terms, which it said informed the decision.
Nearly four years of work with Cursor will continue through the notice period, with OpenAI saying it chose the latest possible cutoff to give developers time to transition and to keep future model Astra out of the deal.
