Elon Musk confirmed on X that SpaceXAI will rebrand to SpaceXSI, aligning with President Trump’s late-September executive order directing federal agencies to replace “artificial intelligence” and “AI” with “Super Intelligence” and “SI” in official documents. The shift follows SpaceX’s February acquisition of xAI and the July rebrand to SpaceXAI, marking the division’s second identity change in under a year as it integrates large language model development, orbital data centers, and Grok capabilities under the broader SpaceX umbrella. Musk described the company as a “super intelligence company” but provided no timeline, and the @SpaceXAI handle and corporate filings remain unchanged as of October 4. Traders are weighing rapid branding momentum against the practical steps required for an official rename, including legal filings, website updates, and product references, with any near-term deadline hinging on how quickly these operational details materialize.
