Elon Musk confirmed on October 4 that SpaceXAI will adopt the SpaceXSI name, aligning the division with President Trump’s September 29 executive order directing federal agencies to replace “artificial intelligence” and “AI” with “super intelligence” and “SI.” Musk posted “No more AI. SI, it’s better” and replied affirmatively to a suggestion of the new branding, while describing SpaceX itself as a “super intelligence company.” The planned shift follows the unit’s July rebrand from xAI after SpaceX’s acquisition earlier in 2026. No timeline, legal filing, or account update has been announced, leaving open questions about the scope and speed of any official change that traders must weigh against the strong public commitment.
