The Roadster's stunning debut earned congratulations from Sam Altman, Elon Musk's long-time rival, who responded calmly.

Tesla's next-generation Roadster made its debut yesterday, with the vehicle performing stunts including inverted climbing, mid-air flips, and jumping over cars during a demo, leveraging SpaceX's cold gas propulsion and underbody suction system. It accelerated from 0 to 60 mph in under 1 second, drawing widespread attention. OpenAI CEO Sam Altman immediately posted on X to congratulate: "The new Roadster looks absolutely stunning, well done Musk." As long-time public rivals, the community was quite surprised by Altman's comment. In response, Musk did not offer a warm direct thanks; instead, in the related discussion thread, he replied "Indeed" to jokes about whether he had canceled Altman's prior canceled order, with a restrained yet teasing tone. The two had prior public disputes over the Roadster. At the end of 2025, Altman posted that he had reserved the vehicle for nearly 7.5 years without delivery, requesting a refund of around $50,000 in deposits, and shared relevant emails. Musk responded that the refund was actually processed quickly, while bringing up OpenAI-related controversies again. This congratulatory post and Musk's calm response have reignited public speculation about the pair's relationship, though their core conflicts have not been resolved.
