Elon Musk to Rename SpaceXAI as SpaceXSI

SpaceX and Tesla CEO Elon Musk has confirmed that SpaceX’s artificial intelligence division, SpaceXAI, will be renamed SpaceXSI, with “SI” standing for Super Intelligence. Musk confirmed the proposed name change on social media platform X.

The rebranding follows a recent move by the U.S. administration to promote the terminology “Super Intelligence” (SI) instead of “Artificial Intelligence” (AI) in executive-branch communications.

Why SpaceXAI Is Being Renamed

On 29 September 2026, U.S. President Donald Trump signed an Executive Order titled “Inaugurating the Era of Super Intelligence.” The order directs executive departments and agencies to use the terms “Super Intelligence” and “SI” in official correspondence, public communications, policy documents and other non-statutory documents, subject to applicable law.

Following this terminology shift, Musk said SpaceXAI would adopt the new name SpaceXSI.

Federal Definition of Super Intelligence

The Executive Order also directs the Assistant to the President for Science and Technology (APST) to propose a federal definition of “Super Intelligence” and “SI.”

The APST is required to examine how such a definition could relate to or modify the existing statutory definition of artificial intelligence and recommend any additional executive actions that may be required.

What Does SpaceXSI Stand For?

• Old Name: SpaceXAI
• AI: Artificial Intelligence
• New Name: SpaceXSI
• SI: Super Intelligence
• CEO: Elon Musk
• Parent Company: SpaceX

The change is primarily a rebranding of terminology, aligning the unit’s name with the U.S. administration’s newly promoted term “Super Intelligence.”
