Elon Musk confirmed on October 4 that SpaceXAI will rebrand to SpaceXSI, aligning with President Trump’s September 29 executive order directing federal agencies to adopt “super intelligence” (SI) terminology over “artificial intelligence” (AI). Musk posted “No more AI. SI, it’s better” and affirmed the name change in reply to an X user, framing SpaceX as a “super intelligence company.” The unit, formed after SpaceX’s February acquisition of xAI and its July rebrand to SpaceXAI, has not yet updated its website, logo, or accounts, leaving the exact timing and scope of an “official” rename—including legal filings or product updates—unclear. Traders are monitoring for rapid implementation driven by Musk’s close ties to the administration versus typical corporate delays in branding or regulatory steps.
