The decision follows SpaceX's acquisition of Cursor in August 2026. OpenAI cited past precedents where companies led by Elon Musk failed to honor contracts, saying it cannot be confident SpaceX will keep use of its technology within the terms of service. OpenAI said the decision was difficult because it wants AI models widely used by developers. It will support developers during the transition period.","whyItMatters":"OpenAI is cutting off a four-year partnership rather than trust SpaceX with its terms of service, citing a contract violation after X came under SpaceX following Musk's acquisition.","webCardHtml":"\u003cp\u003eThe two companies had been partners for four years, but the relationship ends after SpaceX officially completed its acquisition of Cursor in August 2026.
