OpenAI is terminating its contract with coding startup Cursor, citing distrust of SpaceX's ability to meet its terms after conduct by Musk's other firms.
OpenAI announced on Friday that it will terminate its licensing agreement with Cursor, the AI‑powered coding assistant that SpaceX completed a $60 billion all‑stock acquisition of earlier this month. The company gave SpaceX a November 12, 2026 deadline to wind down access to OpenAI models, saying it cannot be confident that the Musk‑owned firm will adhere to OpenAI’s terms of service. The decision cites “past conduct by xAI,” another Musk venture, as evidence that SpaceX may not honor contractual obligations.
The move marks a sharp escalation in the ongoing Altman‑Musk feud that has already seen OpenAI pull its models from other Musk‑linked projects. By cutting off a popular developer tool, OpenAI is signalling that compliance with its usage policies will be enforced even against high‑profile partners. For developers who rely on Cursor’s code‑completion features, the shutdown will require a rapid migration to alternative assistants or direct OpenAI APIs, potentially disrupting workflows and prompting a scramble for replacements.
What follows will hinge on how SpaceX responds to the termination notice and whether the two companies can negotiate a revised arrangement. Observers will watch for any legal push‑back from SpaceX, as well as the broader impact on AI‑tool licensing practices across the industry. The episode also raises questions about how AI providers will vet partners in an environment where corporate ownership can shift quickly, and whether similar contract‑compliance clauses will become standard in future AI‑as‑a‑service deals.
As we reported on August 31, 2026, OpenAI had already ended its agreement with Cursor amid the Altman‑Musk clash; the latest notice formalises the withdrawal and sets a concrete timeline for the split.
