Elon Musk confirmed that SpaceXAI will officially change its name to SpaceXSI to align with President Trump’s new terminology. In a post on September 4, Musk stated, "Yes, we will make that change," responding to inquiries about the rebranding. This decision follows an earlier announcement where he declared, "No more AI. SI. It’s better," accompanied by an image of Nick Bostrom’s book, "Superintelligence." The shift reflects a presidential directive issued on September 29, 2026, during a White House technology summit called the "Super Intelligence Luncheon."

President Trump signed an executive order to replace the term "Artificial Intelligence" with "Super Intelligence," arguing that "artificial" suggests something fake while "super intelligence" better represents the technology’s scale. Several federal agencies have already adopted this new name. On October 4, six days after the summit, Trump formally launched the "Super Intelligence Force" (SIF) via a presidential mandate and announcement on Truth Social. The force is designed to oversee domestic AI policy, ensure American dominance over rivals like China, and work directly with private tech companies.

The rebranding has created uncertainty for many American companies using "AI" in their names. Meanwhile, the total number of registered .ai domains has surpassed one million globally, generating an estimated $96.4 million for Antigua and Barbuda’s 2026 budget, which accounts for nearly half of its government revenue. Speculators are currently purchasing .si domains, often creating look-alike websites that mimic existing .ai sites. As of this report, Musk has not yet applied the "SI" nomenclature across his companies; the X.ai domain still displays "AI" and "Artificial Intelligence" throughout its content.
