SpaceX founder Elon Musk sharply criticized OpenAI's leadership after the company ended its partnership with the developer of the code editor Cursor. "I couldn't care less. Fraudster Altman and Greg Stockman are utterly untrustworthy scoundrels who stole a non-profit open-source project," Musk wrote on social media platform X, as reported by infohub.kz.
OpenAI decided to terminate its partnership with Cursor after SpaceX acquired the company. Cursor's access to OpenAI models is scheduled to be cut off on November 12, 2026. Additionally, future OpenAI models, including Astra, will no longer be available to Cursor. OpenAI stated that Musk's companies violated the terms of cooperation, citing X after its purchase of Twitter and xAI.
Elon Musk was one of the co-founders of OpenAI but later left the company. Since then, he has repeatedly criticized its leadership and the shift from the original non-profit model. In May 2026, a U.S. court dismissed Musk's lawsuit against OpenAI. Federal jurors in Oakland unanimously ruled that the businessman filed the suit too late, as the statute of limitations had expired.
The billionaire sought approximately $150 billion in damages and aimed to revoke OpenAI's commercial status. He alleged that the company and Microsoft had illegally profited from OpenAI's assets after its transition to a for-profit model. During the proceedings, OpenAI representatives stated that Musk was aware of plans to create a commercial arm and initially supported them.
Altman, Brockman, and former OpenAI board member Shivon Zilis also testified in court. Brockman, in particular, claimed that Musk insisted on gaining full control of OpenAI to realize his project of building a city on Mars.
