OpenAI to cut Cursor model access Nov. 12 after SpaceX acquisition
The cutoff directly affects developers who rely on OpenAI models inside Cursor and who do not hold their own API keys. The decision shows how AI providers can use contractual change-of-control clauses to restrict access following ownership changes.
SpaceX acquired Cursor in a $60 billion deal, triggering a change-of-control clause in OpenAI's custom contract with the coding tool. OpenAI announced it will end Cursor's direct model access on November 12, 2026, stating it "cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk's companies violating contracts." OpenAI pointed to Twitter/X and xAI as prior examples, noting that Musk admitted under oath that xAI had violated OpenAI's terms of service. OpenAI said it will not provide future models, including Astra, to Cursor under SpaceX ownership. Cursor users who hold their own OpenAI API keys can continue using them after the cutoff. Anthropic's Tom Brown confirmed Anthropic will continue supporting Cursor, in contrast to Anthropic's earlier decision to pull its models from Windsurf when OpenAI acquired that tool. Anthropic rents GPUs from SpaceX.
Anthropic's Tom Brown confirmed September 3 that Anthropic will continue supplying models to Cursor after SpaceX's $60 billion acquisition of the coding tool, a contrast to OpenAI's November 12 cutoff.
The same reporting noted that Anthropic took the opposite approach with Windsurf, pulling its models when OpenAI acquired that tool, and that Anthropic currently rents GPUs from SpaceX.

OpenAI clarified August 30 that the November 12 termination of its model supply to Cursor applies only to Cursor's institutional agreement, not to individual users.
Users who access OpenAI models through their own API keys will retain that access after the cutoff, which was triggered by SpaceX's $60 billion acquisition of Cursor invoking a change-of-control clause in OpenAI's contract.
OpenAI announced August 28 it will end model access for the coding tool Cursor on November 12, 2026, after SpaceX's $60 billion acquisition triggered a change-of-control clause in its contract.
OpenAI said it 'cannot be confident that SpaceX will use our technology within our terms of service,' citing violations by Twitter/X and xAI and Musk's admission under oath that xAI had breached OpenAI's terms; it will not supply future models, including Astra, to Cursor under SpaceX ownership. OpenAI pledged unspecified support for affected developers.
