Elon Musk Dubs Him 'Scam Altman' Not Sam — Then Altman Clapped Back: 'Homeboy You're The One Selling Space Datacenters'

The AI race isn't just being fought with chips, code, and billion-dollar data centers anymore. Sometimes it's fought 280 characters at a time.

On July 11, Tesla (TSLA) and SpaceX (SPCX) CEO Elon Musk resurrected one of his favorite nicknames for OpenAI CEO Sam Altman, calling him "Scam Altman" on X, formerly Twitter, just one day after Apple (AAPL) sued OpenAI over alleged theft of hardware trade secrets. Altman didn't let the jab sit for long, firing back with a shot aimed squarely at one of the biggest pillars supporting SpaceX's investment story.

"Homeboy you're the one selling public market investors on short-term space datacenters," Altman wrote.

For investors, the exchange was about more than bruised egos. It reignited questions about two competing visions for the future of artificial intelligence—one centered on expanding AI infrastructure here on Earth and the other betting that the next generation of computing could eventually orbit it.

The public exchange is the latest chapter in a relationship that has unraveled over nearly a decade.

Musk helped found OpenAI in 2015 alongside Altman and other researchers as a nonprofit focused on developing artificial intelligence for humanity's benefit. He left the organization's board in 2018, later arguing that OpenAI had abandoned its original mission in favor of commercialization and close partnerships with major technology companies.

Since then, Musk has repeatedly referred to Altman as "Scam Altman" on X while accusing him of transforming OpenAI into a for-profit powerhouse at odds with its founding principles. The feud eventually spilled into courtrooms, public interviews, and competing AI products after Musk launched xAI in 2023.

That rivalry took on even greater significance after xAI merged into SpaceX ahead of the company's June 2026 initial public offering. SpaceX debuted on the Nasdaq under the ticker SPCX in one of the largest IPOs in history, giving public investors direct exposure to Musk's increasingly ambitious AI strategy.

The latest flare-up came one day after Apple filed a lawsuit in federal court against OpenAI, io Products, and former Apple employees Tang Tan and Chang Liu, accusing them of misappropriating confidential hardware trade secrets tied to future Apple devices.

Apple alleges the defendants improperly used confidential engineering information, manufacturing processes, and supplier details to accelerate OpenAI's push into consumer hardware.

"Scam Altman strikes again …" Musk posted before adding, "He takes scamming to a whole new level."

Alongside his criticism of SpaceX's orbital AI ambitions, he added, "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."

"We start flying them next year. Maybe you can come see them if your parole officer approves," he wrote. "After stealing an open source AI charity, you then stole all of Apple's phone technology! Wow. What do you plan for an encore?"
