Elon Musk has confirmed that SpaceXAI, the artificial intelligence company behind the Grok chatbot, will be renamed to “SpaceXSI” in alignment with President Donald Trump’s recent executive order replacing the term “artificial intelligence” with “super intelligence” across federal agencies . Musk made the announcement on X on Sunday, October 4, 2026, in response to a user who asked whether the company could be renamed.
The Confirmation
The exchange began when Musk posted early Sunday that the term “SI” is superior to “AI,” writing “No more AI. SI. It’s better” . Shortly after, a user identified as XFreeze asked whether there was any possibility of renaming SpaceXAI to SpaceXSI . Musk’s response was direct: “Yes, we will make that change” . In a separate post, Musk added that “SpaceX is a super intelligence company”.
The Trump Executive Order
The rebranding follows an executive order signed by President Trump on September 29, 2026, which directs all federal departments and agencies to use “Super Intelligence” (SI) instead of “Artificial Intelligence” (AI) in official communications, public statements, government websites, reports, policy documents, and other non-statutory materials.
The order argues that current frontier technologies have capabilities beyond what the term “artificial intelligence” originally described and that “super intelligence” better reflects their potential . The directive does not require changes to previously issued regulations or historical documents.
What It Means for Grok
According to available reports, the announcement concerns the corporate name of SpaceXAI rather than any changes to Grok’s technology or services . Musk has not provided a timeline for the transition or detailed the logistical steps required, and as of Sunday morning, the company’s website and social media accounts still displayed SpaceXAI . The background of the rebranding can be traced back to February 2026, when xAI was acquired by SpaceX, followed by Musk’s announcement in May that xAI would be merged into SpaceX, with all AI products unified under the SpaceXAI brand in July .
