Musk to rename SpaceX's AI unit SpaceXSI after Trump's 'Super Intelligence' order

Elon Musk said on October 4, 2026 that SpaceX will rename its artificial-intelligence division from SpaceXAI to SpaceXSI. He confirmed the change in a reply to a user on X, after separately posting that AI would be replaced by SI and describing SpaceX as a super intelligence company.

What Trump's executive order says

The move follows an executive order President Donald Trump signed on September 29, 2026, titled "Inaugurating the Era of Super Intelligence." According to the White House fact sheet, the order instructs federal departments and agencies to replace the terms "Artificial Intelligence" and "AI" with "Super Intelligence" and "SI" in official correspondence, public communications, policy documents, websites and reports. References to "AI" in laws passed by Congress are not affected unless lawmakers amend the statutes.

The administration's stated reasoning, per the fact sheet, is that "Artificial Intelligence" implies the technology merely imitates or automates human intelligence, while "Super Intelligence" better reflects what the administration describes as the current and future capabilities of the technology. The fact sheet does not name SpaceX, Musk or any specific company; it instead points to earlier administration initiatives, including the Genesis Mission and the America's AI Action Plan.

According to Fox Business, the order was signed on the same day as a separate, voluntary "White House Accord on Super Intelligence," signed by executives of several AI and technology companies at a White House meeting with the president. Fox Business did not report specific details of what the accord's signatories committed to.

Musk's response and the SpaceX AI unit

Musk, who has publicly used the term "superintelligence" for years and once endorsed philosopher Nick Bostrom's 2014 book on the subject, aligned his company with the new terminology within days of the order. Euronews and Fox Business both reported Musk's confirmation that SpaceXAI will become SpaceXSI, based on his public exchange on X.

Per Teslarati, the division that is being renamed houses the Grok chatbot, the X platform, the Colossus AI training clusters in Memphis, the coding tool Cursor — acquired in August 2026 — and orbital compute infrastructure built on Nvidia hardware. Musk has not given a timeline for the change or said whether it will be a formal legal renaming or a branding update, and it remains unclear whether product names such as Grok or the @SpaceXAI account on X will also change.

A unit that has changed names twice already in 2026

The division has gone through rapid rebranding this year. Teslarati reports that SpaceX acquired xAI on February 2, 2026, in a deal that valued the combined company at $1.25 trillion. Musk announced in May 2026 that xAI would be dissolved as a separate entity, and the unit adopted the name SpaceXAI with a new logo on July 6, 2026 — roughly 90 days before the latest announced change to SpaceXSI.

What is still unknown

• No date has been given for when the SpaceXSI name will formally take effect.
• Musk has not said whether the change is a legal rename or a branding update only.
• It is unclear whether product names such as Grok, or social-media handles like @SpaceXAI, will also be renamed.
• The White House fact sheet on the executive order does not reference SpaceX, Musk or xAI by name; Musk's move is a voluntary alignment with the order's terminology, not something the order requires of private companies.
