OpenAI announced it has notified SpaceX that it intends to wind down the contract providing OpenAI models to Cursor, with a proposed shutoff date of 2026-11-12 — the maximum notice available under the agreement. The reason given: after SpaceX's $60B acquisition of Anysphere closed, OpenAI says it cannot be confident SpaceX will use its technology within the terms of service, citing prior experience with Musk companies (Twitter's ToS breach; Musk admitting under oath that xAI violated OpenAI's ToS). The custom agreement includes a limited change-of-control cancellation window; OpenAI says it will hold the cancellation to the latest possible date while declining to provide future models to Cursor — explicitly naming accountability concerns around the upcoming model Astra. Developers can keep using OpenAI models inside Cursor via their own API key (bring-your-own-key) or the Codex IDE extension.
OpenAI will cut off Cursor's bundled model access on November 12

What this means for you
This is the first major change-of-control fallout of the SpaceX-Cursor acquisition (ev-20260814-06), and it lands on every team using OpenAI models inside Cursor: migrate before 11/12 — BYOK preserves access but changes billing and support posture, and future OpenAI models (Astra) will not ship to Cursor at all. The broader lesson generalizes: model access resold through an intermediary is now exposed to change-of-control clauses, so map which of your tools depend on which vendor contracts before the next acquisition does it for you.

Historical update notes
· Coverage-gap recovery (statements dated 8/29, first seen 2026-08-31 run; wccftech 2026-08-29T15:22Z): Anthropic co-founder & Chief Compute Officer Tom Brown (X, 8/29) — Cursor 'has been a trusted partner of Anthropic since Sonnet 3.5', Anthropic will 'continue to increase compute to support Claude models in Cursor', 'excited for what comes next with them at SpaceX'; Cursor CEO Michael Truell (X, 8/29) — OpenAI models serve about 5% of Cursor user traffic and his team is 'speaking with the OpenAI team to resolve this'. Partially answers the watch item on who fills the Cursor model gap: Anthropic publicly commits to expanding Claude capacity in Cursor; Google models remain available; no xAI statement found. Recommendation stays WATCH.
