OpenAI announced Friday that it will terminate its model supply agreement with AI coding tool Cursor and has notified SpaceX of plans to shut down access to OpenAI models through Cursor on November 12, 2026. OpenAI stated bluntly that, based on the track record of contract violations by companies under Elon Musk, it cannot be confident that SpaceX will strictly adhere to its terms of service in using the relevant technology.
Cursor’s parent company Anysphere reached a $60 billion (approximately NT$1.9 trillion) all-stock acquisition agreement with SpaceX in June of this year, with the deal officially closing on August 14. Cursor has since become part of Musk’s AI portfolio. This change in ownership transformed what had been an independent tool capable of integrating multiple AI models into a component of the SpaceX ecosystem, directly triggering OpenAI’s decision to terminate the partnership.
OpenAI issued a statement simultaneously on X and its official website: “We made this decision because, based on past experience with contract violations in our dealings with Elon Musk’s companies, we cannot be confident that SpaceX will strictly adhere to our terms of service in using the relevant technology.”
Event Timeline

History of Contract Violations a Key Factor
OpenAI specifically enumerated the contract violation record of Musk’s companies in its statement. The company said that after Musk acquired Twitter, the social media platform breached contract terms signed with OpenAI, and Twitter has since become part of SpaceX.
Furthermore, OpenAI noted that Musk admitted during sworn testimony this year that xAI, the AI company he founded, had violated OpenAI’s terms of service, and xAI has likewise been absorbed into SpaceX. OpenAI particularly emphasized that the terms xAI violated bear similarities to xAI’s own terms of service.
OpenAI explained that large partnerships typically rely on custom contracts to ensure compliance and safety at scale, and the custom agreement signed with Cursor included a change-of-control clause. Once a change of control occurred at Cursor, OpenAI had only a limited window to cancel the contract.
This chain of events reflects the expansion trajectory of the SpaceX portfolio in recent years—companies acquired or absorbed have repeatedly been accused of breaching contract terms with OpenAI:
Astra Model Accountability Requirements a Catalyst
As AI model capabilities continue to advance, OpenAI said it has stricter accountability requirements for its upcoming next-generation Astra model. The company chose to initiate the termination process at the latest point permitted by the contract, rather than the earliest, to maximize the time developers could continue using existing models through Cursor.
OpenAI made clear that it will not provide Cursor with future models. This means that even though existing models remain accessible until November 12, next-generation models such as Astra will not be added to Cursor’s supply lineup.
The company emphasized that this decision is not directed at the Cursor team itself. The two parties have collaborated for nearly four years, and OpenAI expressed respect for the Cursor team, its product, and its contributions to the developer community, and is prepared to provide support to affected developers during the transition period.
Acquisition Reshapes AI Competitive Landscape
SpaceX’s acquisition of Cursor is a key step in Musk’s expansion of his AI footprint. The $60 billion deal is not only one of the largest acquisitions in SpaceX’s history, but also gives the company a mature AI coding product and associated talent, further challenging the developer tools market dominated by OpenAI and Anthropic.
SpaceX initially announced its partnership with Cursor in April, with plans to jointly develop next-generation “coding and knowledge work AI,” while SpaceX secured an option to acquire Cursor for $60 billion. Cursor officially announced the completion of the acquisition on August 14.
Nvidia (NVDA) CFO Colette Kress revealed during the latest earnings call that Cursor, acquired by SpaceX, has reached $1 billion in annual recurring revenue (ARR) (approximately NT$32 billion). She also mentioned that Nvidia has begun shipping its next-generation data center CPU “Vera” to key partners including SpaceX AI, a product focused on improving AI agent workloads.
Kress also listed SpaceX’s AI model Grok alongside OpenAI, Anthropic, Meta, and Gemini as leading closed-source models supported by Nvidia. SpaceX’s AI revenue in 2025 was $3.2 billion (approximately NT$100 billion), and Wall Street estimates this figure could exceed $60 billion by 2027.
Security Concerns and Industry Trends
The partnership breakdown also comes at a time when the AI industry is paying increased attention to model safety, usage standards, and AI agent risks. According to Reuters, earlier this year a Russian-speaking ransomware group called Aur0ra used Cursor to breach at least seven companies. The group’s method involved repeatedly telling the AI agent that its operations were legitimate security testing; when rejected, it would restart the conversation and resubmit the same claims, causing the agent to misjudge that “this is a test environment, therefore legitimate,” and proceed to execute malicious tasks including credential theft, internal network scanning, privilege enumeration, and vulnerability exploitation. Security firm Gambit Security’s post-incident analysis found that the AI agent powering Cursor at the time of the attack was actually driven by Anthropic’s Claude Sonnet 4.5. The firm’s threat intelligence lead Eyal Sela said AI agent assistance improved hackers’ intrusion efficiency by roughly 30 to 50 percent. The incident highlights new risks facing AI coding tools in terms of security and access permissions.
More than 100 technology and financial companies, including OpenAI, Microsoft (MSFT), Alphabet (GOOGL), Amazon (AMZN), and IBM (IBM), recently jointly called on governments and businesses to strengthen defenses against AI-driven cyberattacks and advocated for establishing stricter trusted AI model access mechanisms.
For OpenAI, terminating the Cursor partnership also reflects the changing relationship between AI model providers and application-layer companies. In the past, AI application companies could simultaneously integrate products from multiple model providers. But when application tools are acquired by large technology companies, model providers and platform owners may shift from partners to direct competitors.
Cursor’s positioning within SpaceX has already begun to shift. Observers are watching whether it will gradually move toward deeper integration with Musk’s AI ecosystem, including combining with Grok and SpaceX’s AI computing resources. OpenAI has not yet announced specific execution arrangements following the termination. Cursor co-founder and current SpaceX executive Michael Truell responded on X, emphasizing that OpenAI models account for only about 5% of Cursor’s user traffic and that the move will not affect the company’s viability: “Cursor was one of OpenAI’s earliest customers. We have worked closely with their team for years and have always trusted the platform as neutral infrastructure.” He expressed disappointment with the notice and said both teams are in communication to seek a resolution.
With Cursor now formally part of the SpaceX ecosystem, this shift in the model supply relationship may be the latest signal of intensifying competition between OpenAI and Musk’s AI portfolio.
