Elon Musk pledges SpaceXSI rebrand after Trump's executive order to use 'Super Intelligence' moniker

Elon Musk has announced that SpaceX will rebrand itself as SpaceXSI, aligning with the new moniker "Super Intelligence" popularized by President Trump. In a September 4 X post, Musk confirmed the change to reflect the presidential designation. Earlier, he hinted at the rebrand by stating, "No more AI. SI. It's better," alongside an image from Nick Bostrom's book, "Superintelligence."

On September 29, 2026, President Trump signed an executive order to officially transition "Artificial Intelligence" to "Super Intelligence" at a technology summit known as the "Super Intelligence Luncheon." The administration claimed that "artificial" suggests artificiality, while "super intelligence" better conveys the technology's magnitude and promise.

Federal agencies promptly adopted the rebranding. Six days later, President Trump formally established the "Super Intelligence Force" (SIF) via a presidential decree and announcement on Truth Social, promising to champion AI and foster its growth, with the force reporting directly to the White House. The SIF aims to safeguard American AI supremacy against global powers like China and coordinate with the private tech industry.

The impact of the rebrand on existing AI companies and the surge in .ai domain registrations remain uncertain. As of now, Musk has not yet updated all SpaceX entities with the "SI" moniker; the X.ai domain still prominently displays "AI" and "Artificial Intelligence."
