OpenAI Sets November 12 Cutoff for SpaceX’s Cursor Following Anysphere $60B Acquisition
SAN FRANCISCO — OpenAI announced on Friday its intention to terminate its AI model supply agreement with Cursor, the popular AI-powered software coding assistant developed by Anysphere and recently acquired by Elon Musk’s SpaceX in an all-stock transaction valued at $60 billion.
The move marks a sharp commercial escalation in the longstanding legal and strategic battle between OpenAI Chief Executive Sam Altman and SpaceX founder Elon Musk.
OpenAI cited contractual trust concerns regarding Musk's corporate entities as the primary basis for the termination. In an official blog post, OpenAI stated: "We are taking this decision because we cannot be confident that SpaceX will use our technology in compliance with our Terms of Service, based on our past experience with Elon Musk’s companies violating contracts."
Key Strategic & Operational Developments:
Acquisition & Change of Control: SpaceX agreed to acquire Anysphere for $60 billion in June, closing the deal earlier this month. OpenAI stated that its commercial partnership agreement with Cursor included a change-of-control provision providing a defined window to terminate upon acquisition.
Effective Cutoff Date: OpenAI proposed November 12, 2026, as the official termination date for Cursor’s direct access to OpenAI foundation models (including GPT-series developer APIs).
Multi-Model Alternative Ecosystem: While Cursor historically relied heavily on OpenAI as an early integration partner, the coding workspace also natively integrates SpaceX’s Grok (developed by SpaceXAI/xAI) alongside frontier models from Anthropic and Google.
Ongoing Legal Friction: The decision follows a series of high-profile legal battles between Musk and Altman, including a $150 billion lawsuit challenging OpenAI’s restructuring that a federal jury decided in favor of Altman earlier this year.
Michael Truell, co-founder of Cursor and currently an executive at SpaceX, confirmed on X that Cursor leadership is actively engaging with OpenAI’s technical and commercial teams to seek a resolution, noting that Cursor had long viewed OpenAI as neutral developer infrastructure.
