OpenAI Cuts Cursor Model Access After SpaceX Acquisition
Synopsis
OpenAI will end direct model access for Cursor in November following SpaceX’s US$60 billion acquisition of its parent company, highlighting the growing commercial and strategic rivalry between major AI players.
OpenAI is ending direct access to its AI models for Cursor, escalating the technology rivalry surrounding Elon Musk after SpaceX completed its US$60 billion acquisition of Cursor’s parent company, Anysphere.
OpenAI has told SpaceX that its model access through Cursor will end on November 12, citing concerns that Musk-owned companies may not comply with its contractual terms.
The decision follows the August 14 completion of SpaceX’s acquisition, which gave Cursor an implied equity value of US$60 billion.
OpenAI has pointed to previous disputes involving Musk’s companies, including allegations surrounding the use of OpenAI technology by xAI.
Musk responded by criticising OpenAI’s leadership, adding another chapter to his long-running dispute with OpenAI CEO Sam Altman.
Limited Exposure for Cursor
The immediate impact on Cursor may be smaller than the headline suggests. Cursor CEO Michael Truell said OpenAI models account for only about 5% of the platform’s user traffic.
That means Cursor already relies heavily on other AI providers. The platform supports models from Anthropic, Google, SpaceXAI and other developers, giving users alternatives as OpenAI access winds down.
Anthropic has also moved quickly to reassure Cursor users. Anthropic co-founder Tom Brown said the company would continue providing Claude models and increase computing capacity to support their use on the platform.
The roughly two-and-a-half-month transition period also gives Cursor time to replace its remaining OpenAI dependency.
A Bigger Battle Over AI Infrastructure
The dispute nevertheless highlights the strategic risks created when AI companies become increasingly interconnected.
SpaceX’s acquisition places Cursor inside Musk’s expanding technology ecosystem, while OpenAI is simultaneously developing its own coding products and AI infrastructure. Ending the relationship could therefore be about more than the relatively small share of Cursor traffic using OpenAI models.
For SpaceX, the acquisition remains a major AI bet. The company completed the transaction by issuing approximately 389.3 million Class A shares based on the US$60 billion implied value of Anysphere.
The next question is whether Cursor can replace OpenAI without affecting developers’ workflows. With 95% of its traffic already coming from other models, the immediate disruption may be limited. But the episode shows how ownership changes can quickly reshape access to critical AI technology and expose the growing commercial rivalry between the industry’s leading model providers.
