OpenAI announced it will terminate its model-hosting contract with Cursor, scheduling the shutdown for November 12, 2026 because it cannot confirm that SpaceX will comply with OpenAI’s terms of service. Cursor co-founder Michael Truell said OpenAI accounts for only about 5% of Cursor’s traffic and was chosen for its neutrality, while Elon Musk stated he “couldn’t care less.”
