Musk appeared alongside Trump and other AI leaders at the White House last week as the president rolled out a new “accord” on AI. The document imposes some guidelines to help ensure AI is developed responsibly, but Trump has described it as being only “morally binding”—and at roughly 300 words, the accord does not impose any significant guardrails or detailed regulations on the industry. Trump also signed an executive order last week ordering the government to now refer to AI as “super intelligence,” which Musk has endorsed, writing on X on Sunday, “No more AI,” and arguing “SI” is “better.” The trillionaire said on X that SpaceXAI, a subsidiary of SpaceX that operates chatbot Grok, would be renamed to “SpaceXSI,” though the company has not appeared to make any formal efforts to rebrand as of Monday morning.
Musk’s net worth jump also comes days after his former girlfriend Shivon Zilis revealed on social media Friday she had been “let go” from their relationship, writing, “It’s hard to go from in love to let go in a week with no warning, but that’s just how it is sometimes.” Zilis and Musk have four children together, and Zilis—an executive at Musk’s Neuralink—testified in court in May that the two were solely friends and colleagues before they became romantic partners, with Musk initially donating his sperm to Zilis so she could have their first two children via IVF.
