OpenAI to end model access to Cursor after acquisition by Elon Musk's SpaceX
OpenAI terminated its billion-dollar model supply agreement with AI coding tool Cursor following the acquisition of parent company Anysphere by Elon Musk's SpaceX. OpenAI invoked a change-of-control clause to walk away from the partnership, which was projected to generate more than $1 billion in annual revenue. The decision transforms model access into a direct corporate weapon amid escalating rivalries. Meanwhile, Cursor co-founder Aman Sanger remains in the spotlight, and SpaceX's all-stock acquisition follows an initial agreement reached in June.
What changed
Corroborating reports confirm that SpaceX completed its all-stock acquisition of Anysphere in August, prompting OpenAI to invoke its change-of-control clause exactly two weeks later on August 28, 2026.

OpenAI Cuts Off Cursor After SpaceX Deal
OpenAI terminated its billion-dollar model supply agreement with AI coding tool Cursor following the acquisition of parent company Anysphere by Elon Musk's SpaceX. OpenAI invoked a change-of-control clause to walk away from the partnership, which was projected to generate more than $1 billion in annual revenue. The decision transforms model access into a direct corporate weapon amid escalating rivalries. Meanwhile, Cursor co-founder Aman Sanger remains in the spotlight, and SpaceX's all-stock acquisition follows an initial agreement reached in June.
Why it matters
The cancellation highlights how major artificial intelligence providers are willing to sacrifice massive revenue streams to avoid supplying technology to competing corporate figures. OpenAI cited a lack of trust and contract violations involving Musk's companies when ending the arrangement. Access for Cursor is scheduled to officially terminate on November 12, though Cursor leadership claims the affected models account for only a small fraction of its platform traffic.
What is confirmed
- SpaceX completed its all-stock acquisition of Cursor maker Anysphere after a June agreement.
- OpenAI invoked its change-of-control clause on August 28, 2026.
- OpenAI estimated its partnership with Cursor would generate more than $1 billion in revenue a year.
Still unconfirmed
- OpenAI ended the agreement due to a lack of trust and contract violations involving Musk's companies.
What to watch next
- The official termination of OpenAI model access to Cursor on November 12, 2026.
- Potential migration of Cursor to alternative large language models or internally developed architectures following the cutoff.
