OpenAI cuts off Cursor's access after SpaceX acquisition

First reported

OpenAI ran this on , a day before the other 3 sources picked it up.

  • OpenAI is ending Cursor's direct access to its models on November 12, 2026, citing distrust of SpaceX and Elon Musk's history of contract violations.
  • Cursor users can still access OpenAI models by providing their own API keys, and the coding tool only relied on OpenAI for about 5 percent of its AI traffic.
  • Anthropic, a competing AI company, announced it would keep supporting Cursor after the acquisition, though Anthropic has previously blocked other tools from accessing its models.
  • The move reflects an ongoing dispute between Musk and OpenAI leadership dating back to Musk's departure from OpenAI's board in 2018 and his subsequent lawsuit against the company.
