SpaceXAI wants to rename itself again for Donald Trump

Elon Musk’s AI company only changed its name from xAI to SpaceXAI last July. Now it may be heading for another switch. In a post on X, Musk said the company could soon be called SpaceXSI, after Donald Trump said AI should officially be called “Superintelligence.”

Musk framed it the same way Trump does: “No more AI, SI is better.” He also wrote that “SpaceX is a superintelligence company.” The name change came up in reply to a question on X about whether SpaceX’s AI arm could become SpaceXSI.

So far, though, this is still talk. The company’s name on X remains SpaceXAI, and Musk’s own links still point to a page that prominently uses “AI.” That makes the whole thing feel less like a completed rebrand and more like Musk testing how far he can push Trump’s latest terminology.

And Trump seems happy to play along. He had already introduced the leadership of a new “Super Intelligence Force” at the weekend, and he shared one of Musk’s posts in a screenshot on his own social network. The optics matter here: Musk, who had fallen out with Trump after serving as a “special government employee” and leading the “Department of Government Efficiency,” appears to be back in the president’s good graces. Musk’s stint ended in May 2025, after reports of a rift. Now there are reports he may even be tasked with researching the future of warfare for the US Department of Defense.
