OpenAI Ends Cursor Contract: SpaceX Acquisition & 2026 Transition

OpenAI plans to end its contract providing models to the AI coding platform Cursor. This follows SpaceX's acquisition of Cursor. OpenAI has proposed November 12, 2026, as a transition date. This is not a final termination date, but a proposed period. Existing OpenAI models are expected to remain available during this time. Here's the thing: OpenAI stated it cannot be confident that SpaceX will use its technology within OpenAI’s terms of service. The company cited previous experiences with Elon Musk-controlled companies, including claims that Twitter and xAI violated terms of service. What's interesting is that OpenAI's agreement with Cursor allowed it to cancel the contract after a change in control, which occurred with the SpaceX acquisition. The bottom line is that while current models might remain for a period, OpenAI will not provide future models, like Astra, to Cursor. Cursor's co-founder Michael Truell said OpenAI models account for about 5% of their traffic, and discussions are ongoing. This impacts how developers will access future OpenAI advancements through Cursor.
