Space Exploration Technologies Corp. Class A Common StockOpenAI cuts off model access due to SpaceX acquisition, citing trust issues with Musk's companies.

OpenAI will end model access through Cursor on November 12, following SpaceX's $60 billion all-stock acquisition of Cursor's parent company, Anysphere, which closed on August 14. OpenAI cited concerns that SpaceX might not comply with its terms of service, referencing disputes with Elon Musk's companies, including xAI's admission of training on OpenAI's output. Cursor CEO Michael Truell said OpenAI models handle about 5% of Cursor's user traffic, and discussions are ongoing. Musk responded by calling OpenAI's leadership "utterly untrustworthy," while Anthropic's co-founder Tom Brown said his company will increase compute to support Claude in Cursor. The financial impact appears limited given the small traffic share, but the dispute highlights broader reputational and partnership risks for SpaceX.
