OpenAI cuts off Cursor AI model access after SpaceX acquisition of coding startup
OpenAI announced it is terminating developer access to its AI models via Cursor, the AI coding tool now owned by SpaceX, effective November 12, 2026, and will not provide future models to the service. OpenAI cited lack of assurance that SpaceX will abide by its terms of service, pointing to experience with Elon Musk's companies violating contracts and Musk's courtroom admission that xAI trained its models on OpenAI's output. Cursor co-founder Michael Truell disclosed that OpenAI models account for roughly 5% of the platform's user traffic and said the team is in talks with OpenAI. SpaceX completed its $60 billion all-stock acquisition of Anysphere, Inc., Cursor's parent company, on August 14. The dispute is part of a broader conflict between Musk and OpenAI, with Musk having sued OpenAI in 2024 over its transition to a for-profit structure, losing a jury ruling in May 2026. Anthropic co-founder Tom Brown offered to increase compute for Claude models in Cursor, while Replit CEO criticized Anthropic's own record of cutting off Windsurf.

SpaceX completed its $60 billion all-stock acquisition of Cursor's parent company Anysphere on August 14. The deal followed Cursor rebuffing two acquisition approaches from OpenAI. SpaceXAI and Cursor had jointly trained Grok 4.5, a coding-focused AI model, in July. Anthropic offered to increase compute for Claude models in Cursor, while Replit CEO criticized Anthropic's past actions. The dispute is part of a broader conflict between Musk and OpenAI, with Musk having sued OpenAI in 2024 over its for-profit transition, losing in court in May 2026.
OpenAI Cuts Off Cursor Access After SpaceX Merger, Escalating Altman-Musk Feud
OpenAI revoked API access for Cursor, an AI coding platform, immediately after SpaceX completed its $60 billion acquisition of the company. OpenAI cited a pattern of contract violations by Elon Musk's companies as the reason. The move escalates the long-running feud between OpenAI CEO Sam Altman and Elon Musk. SpaceX's Colossus clusters, targeting the equivalent of 1 million Nvidia H100 chips, now power Cursor's $4 billion revenue base, reducing dependence on rival AI suppliers. OpenAI served only about 5% of Cursor's traffic. Analysts set an average price target of $219 on SpaceX, implying over 50% upside. The vertical integration strategy mirrors SpaceX's playbook that collapsed launch costs. Cursor can still route developers to other providers like Anthropic's Claude, but future OpenAI models like Astra are off the table, pushing SpaceX toward proprietary Grok-powered coding agents.

OpenAI Gives Cursor 75 Days' Notice Before Cutting Model Access
OpenAI provided Cursor with the maximum contractual notice period of 75 days before terminating access to its models on November 12. The notice affects both current and future models. The post, from an X user, offers to share vendor-risk questions upon request, indicating a potential business or security concern related to the termination.
OpenAI Cuts Off Cursor After SpaceX Acquisition by Elon Musk
OpenAI announced it will terminate Cursor's direct access to its models on November 12, 2026, following SpaceX's $60 billion acquisition of the AI coding tool. The decision stems from trust concerns over Elon Musk's ownership, citing past contract violations by Musk's companies. OpenAI's unreleased next-generation model, Astra, will never be provided through official channels. Developers can still use GPT in Cursor by bringing their own OpenAI API key or using OpenAI's Cursor IDE extension, but this shifts costs from a bundled subscription to a pay-per-token model. Cursor CEO Michael Truell confirmed OpenAI models account for about 5% of user traffic and that negotiations are ongoing. The move is part of a broader trend of AI model providers restricting access to tools owned by competitors, with similar actions by Anthropic against Windsurf and xAI.
OpenAI to end model access to Cursor after SpaceX acquisition by Elon Musk
OpenAI announced it will end developers' access to its AI models on Cursor, the AI coding startup recently acquired by Elon Musk's SpaceX for $60 billion. The proposed cutoff date is November 12, 2026. OpenAI cited an inability to trust that SpaceX will comply with its terms of service, referencing past contract violations by Musk's companies. Cursor CEO Michael Truell stated that OpenAI models account for only about 5% of Cursor user traffic and that discussions with OpenAI are ongoing. The move escalates the long-running feud between Elon Musk and OpenAI CEO Sam Altman, which includes Musk's failed lawsuit over OpenAI's for-profit conversion. SpaceX had previously acquired Musk's X and xAI before going public. The decision follows a similar move by rival Anthropic, which cut off model access to Cursor last June.

The development comes as the AI-assisted coding market heats up, with OpenAI planning to go public next year and rival Anthropic also considering an IPO.
Altman-Musk Feud Escalates as OpenAI Cuts Off Cursor Access After SpaceX Merger
OpenAI CEO Sam Altman escalated his feud with Elon Musk by cutting off API access to Cursor, a coding platform recently acquired by SpaceX for $60 billion. OpenAI cited Musk's history of contract violations as the reason, though Cursor relied on OpenAI for only 5% of its traffic. The move highlights SpaceX's vertical integration strategy, leveraging its Colossus clusters (targeting 1 million H100 equivalents) to power Cursor's $4 billion revenue base and reduce dependence on rival AI suppliers. Analysts set a $219 average price target on SpaceX, implying over 50% upside. The dispute pushes SpaceX toward proprietary Grok-powered coding agents, while Anthropic has signaled increased support for Cursor. The article also includes a promotional segment for an analyst's top AI stock picks.
OpenAI proposes removing model access from Cursor on November 12 amid trust concerns
OpenAI has proposed removing access to its AI models from the coding platform Cursor, effective November 12, according to a social media post by analyst alliekmiller. The proposal sparked reactions from OpenAI, Cursor CEO, and Anthropic founder on X. The analyst interprets OpenAI's Friday night post as a negotiation tactic, expressing distrust toward SpaceX (led by Elon Musk, which recently acquired Cursor). Cursor's CEO appeared surprised and downplayed OpenAI's traffic share, questioning neutrality. Anthropic's founder reaffirmed trust in Cursor and highlighted continued compute support, framing the SpaceX acquisition positively. The analyst doubts OpenAI will continue model access to a Musk-led company unless SpaceX's structure changes significantly. The underlying theme is trust: its duration, who holds the relationship, what damaged it, and how to preserve it.
