Our decision on Cursor following its acquisition by SpaceX

OpenAI announced its decision to terminate its contract with Cursor, effective November 12, 2026, following Cursor's acquisition by SpaceX. This action stems from OpenAI's inability to ensure SpaceX's compliance with its terms of service, citing past contractual breaches by Elon Musk's companies, including Twitter and xAI, now part of SpaceX. OpenAI expressed regret for the impact on developers and pledged full support during the transition.

This decision marks the first time OpenAI has publicly cited past contractual breaches by Elon Musk's companies as the reason for terminating a partnership.
