OpenAI to End Model Access for SpaceX-Owned Cursor
Cursor is a widely used AI coding editor that relies on outside providers, including OpenAI, to power key developer features. Its acquisition by SpaceX shifted control to Elon Musk’s aerospace company, forcing model suppliers to reassess data governance, commercial rivalry and counterparty risk. The dispute shows how a change in ownership can quickly disrupt the supply relationships underpinning AI products.
OpenAI will stop supplying new models directly to SpaceX-owned Cursor and terminate access to existing models on Nov. 12, ending the companies’ partnership. Reports attributed the decision to OpenAI’s distrust of Musk, whose long-running feud with Chief Executive Sam Altman includes arguments over the AI company’s nonprofit origins. Anthropic responded by signaling increased support for Cursor, positioning its Claude models to absorb displaced demand.

The history behind this eventSpaceX Closes Cursor Acquisition, Brand Faces Phaseout
Cursor built its reputation around an AI coding assistant designed to help developers generate, understand and revise software. SpaceX’s acquisition of the startup signals a deeper push into artificial intelligence and automated software development, with Cursor’s technology potentially supporting a broader range of agent-based tools. The deal also raises questions over how the product will fit alongside other AI initiatives associated with the SpaceX ecosystem.
SpaceX has officially closed its acquisition of Cursor, according to the latest reports, though the companies have not disclosed the exact closing date or financial terms. The Cursor name may be phased out over the coming months, while a general-purpose AI agent under development could be renamed Grok Bot. SpaceX has yet to announce a detailed integration timetable or confirm the final branding of the product.
SpaceX Acquires AI Coding Startup Cursor for $60 Billion
Cursor is an AI coding tool developed by Anysphere that helps users generate, modify and understand code. SpaceX's acquisition of the startup is intended to integrate development tools, model training and aerospace engineering software while connecting AI computing resources across Elon Musk's companies, reshaping the generative AI and space industry landscape.
As of July 19, 2026, SpaceX had announced an all-stock acquisition of Cursor valued at $60 billion, paid primarily in SpaceX equity rather than cash. The companies will combine Cursor's AI coding capabilities with the Colossus training supercomputer to strengthen model training and real-world applications. Reports have not disclosed a closing date.
SpaceX Secures Option to Acquire AI Coding Startup Cursor in Deal That Could Reach $60 Billion
Cursor is a startup focused on AI-assisted software development. SpaceX and Elon Musk’s xAI aim to combine its coding technology with the Colossus supercomputer to improve model training and software-development efficiency. The move could further integrate Musk’s AI businesses and is seen as an important step in challenging OpenAI and Anthropic.
The latest reports say SpaceX has moved beyond securing an acquisition option and formally signed a $60 billion all-stock deal with Cursor, with closing expected in the third quarter of 2026. An earlier agreement was also reported to include a $10 billion breakup fee. During the same period, xAI launched Grok Build, supporting up to eight parallel AI agents and a 2 million-token context window.
