OpenAI cuts off Cursor after SpaceX takeover
OpenAI is pulling the plug on Cursor’s AI access in November, after SpaceX reportedly entered the chat.
Another chapter in the Sam Altman-Elon Musk saga has arrived, this time with an AI coding tool caught in the middle.
OpenAI has said it plans to stop providing its AI models to Cursor, the coding platform now owned by Elon Musk’s SpaceX. The decision, announced on 28 August 2026, could bring an end to a partnership that gave Cursor users access to OpenAI’s models.
OpenAI said it has notified SpaceX that it intends to wind down the agreement, with access expected to end on 12 November 2026. The company said that gives developers the maximum notice allowed under the contract.
Why OpenAI is pulling the plug
OpenAI says the issue comes down to trust. The company said it has concerns about whether SpaceX would use its technology in line with its terms of service, pointing to previous issues involving Musk-led companies and alleged contract violations.
There is also a bigger issue at play. OpenAI’s models are becoming increasingly powerful, so the company wants greater control over their deployment, particularly when working with large organisations. Custom agreements can set rules around access, usage and safety.
And this may not stop with the models Cursor currently uses. OpenAI said it will not provide future models to Cursor either, including a reference to its upcoming Astra model. This looks less like a routine contract change and more like OpenAI drawing a line.
So what happens to Cursor users?
Cursor is a popular AI coding tool that helps developers write, edit and understand code. It supports models from multiple providers, so losing OpenAI access does not mean Cursor suddenly stops working.
But developers who specifically rely on OpenAI models could have fewer choices inside the platform once the agreement ends. Cursor may also need to adjust how it packages and offers different models to users.
The situation is a useful reminder that AI products are often more interconnected than they appear. A developer may think they are simply using Cursor, but the experience can depend on agreements between several companies behind the scenes.
And yes, Musk and Altman are involved
It is difficult to ignore the Musk factor here. Musk co-founded OpenAI before leaving the company and later became one of its biggest critics. Since then, his AI ambitions have expanded through xAI and other businesses.
Now, with SpaceX owning Cursor, another Musk-linked company sits directly in the middle of a dispute with OpenAI. For the wider AI industry, the story is bigger than one contract. Model access is becoming a strategic advantage, and companies are becoming increasingly careful about who gets to use their technology.
