Musk says SpaceXAI will be renamed SpaceXSI after Trump superintelligence decree
In short
Elon Musk said the company SpaceXAI will be renamed SpaceXSI, replacing the abbreviation AI with SI, for superintelligence. The change follows a decree signed by US President Donald Trump on 29 September requiring federal departments and agencies to use the term Super Intelligence instead of Artificial Intelligence. Musk confirmed the plan in replies on X; the SpaceXAI name itself dates only from July 2026, after SpaceX acquired xAI in February.
Why it matters
The renaming ties a major private technology company's identity to a US federal terminology shift, so official wording in Washington may start showing up in corporate branding. Musk's statements carry broad reach given his companies' roles in space, social media and AI. The documents do not indicate that the terminology change alters any underlying technology or regulation.
