Sam Altman responded sharply after Elon Musk revived his "Scam Altman" jibe on X, days after Apple sued OpenAI. Musk opened the exchange by calling Altman "Scam Altman" and writing, "Scam Altman is super good at scamming," followed by posts including, "He [Altman] might literally love scamming more than any human alive!" Altman replied within hours, pointing to SpaceX's own ventures: "Homeboy you're the one selling public market investors on short-term space datacenters," referring to SpaceX's reported plans to deploy data centres in space through its Starlink and Starship projects. Musk shot back, "We start flying them next year. Maybe you can come see them if your parole officer approves. After stealing an open source AI charity, you then stole all of Apple's phone technology!" Altman later took a separate dig while discussing OpenAI's latest AI model, writing, "There are a lot of benchmarks that suggest 5.6 Sol is the best model in the world right now, but the most reliable way to tell is that Elon is obsessed with me again." The exchange is the latest in a long feud rooted in Musk's 2018 exit from OpenAI and a lawsuit he lost in May 2026.
