💼 OpenAI terminates contract with Cursor after its acquisition by SpaceX
On August 28, 2026, OpenAI published a post titled "Our decision on Cursor following its acquisition by SpaceX": the company notified SpaceX of the termination of the agreement under which its models were provided to the Cursor service (Anysphere). SpaceX closed this deal on August 14, 2026, for $60 billion — this is the largest startup acquisition in history. Disconnection is proposed for November 12, 2026: OpenAI is using the maximum notice period under the contract, active models will continue to work until this date, but future ones — including the announced Astra — Cursor will not receive. OpenAI's motivation: "we cannot be sure that SpaceX will use our technology within the terms of our service", with reference to the experience of terms violations by Elon Musk's companies. Reuters confirms: SpaceX has not commented on the decision.
🌍 For the first time, a frontier model provider has terminated a contract with a popular intermediary tool not because of price, but because of distrust of the new owner after the purchase. API access agreements are in fact becoming a lever between laboratories — following the example of Anthropic's ban against xAI. For wrapper developers, this is a signal to diversify models and look at open-source, and for laboratories — to keep the latest models like Astra for their own services.
👤 If you use Cursor with OpenAI models, access will cease by November 12, 2026. According to the founder of Cursor, these models accounted for only about 5% of the service's load — a figure from a discussion on Hacker News without independent confirmation, so the main stack (Composer, grok-cursor, Anthropic) is not affected. It is useful to watch whether Anthropic will follow: its decision may not be made due to contracts with the Musk ecosystem.
