WASHINGTON, Oct. 4 (DC Times Online) — SpaceX’s artificial intelligence business is headed for another name change, this time from SpaceXAI to SpaceXSI. The proposal follows President Donald Trump’s directive to change the language used by federal agencies, but that order does not require private companies to rename themselves.
SpaceX CEO Elon Musk agreed to the proposed name in an Oct. 4, 2026, reply on X. Asked about changing SpaceXAI to SpaceXSI, he wrote: “Yes, we will make that change.” His statement describes a future change, not a completed rebrand.
What do AI and SI mean here?
AI stands for “artificial intelligence.” SI is short for “super intelligence,” the wording Trump has urged the government to adopt. Musk’s proposed name replaces the AI ending in SpaceXAI with SI.
In separate posts early Oct. 4, Musk wrote “No more AI,” “SI” and “It’s better.” He also declared: “SpaceX is a super intelligence company.” Those posts expressed his preference for the new terminology rather than describing a new product feature.
The business involved is SpaceX’s AI unit, previously known as xAI. Its products include the Grok chatbot. Musk’s proposal concerns the unit’s name; it does not announce a change to Grok’s capabilities.
What did Trump direct the government to do?
Trump signed an executive order on Sept. 29 directing federal departments and agencies to use “Super Intelligence” and “SI” instead of “Artificial Intelligence” and “AI” in specified official communications, to the maximum extent permitted by law. The order, identified as Executive Order 14434, addresses federal bodies, not private-company names.
Before signing it, Trump promoted the terminology during a September speech to the United Nations General Assembly.
“From this point forward, all of United States documents, and hopefully the world’s will be changed to use the much more accurate term ‘super’ as opposed to artificial. So it’s super intelligence,” Trump said.
His speech expressed a broader ambition for the wording to be used worldwide. The executive order’s requirements apply to U.S. federal departments and agencies.
Why would this be a second name change?
The move would follow the shift from xAI to SpaceXAI earlier in 2026.
Teslarati reported that SpaceX acquired xAI on Feb. 2 in a transaction that valued the combined company at $1.25 trillion. Yahoo Finance also placed the acquisition in February. Fox Business gave a different account, placing the acquisition in July and describing it as a $1.25 trillion deal.
Those reports differ on both the acquisition date and what the dollar figure represents: a combined-company valuation is not the same as the price paid for an acquisition.
In May, Musk described his plan for the acquired business: “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX.”
On July 6, xAI adopted the SpaceXAI name and a new logo, and its X account changed its handle, Yahoo Finance reported. The proposed SpaceXSI name would therefore be another identity change within the same year, following that completed rebrand.
Has the new name taken effect?
Public branding still used SpaceXAI when news organizations checked on Oct. 4. Reuters reported that the unit’s X account had not changed its name at publication. Forbes separately reported that the company’s website and social accounts still said SpaceXAI on Sunday morning.
Teslarati reported that the company had not issued a formal announcement as of Sunday morning. CTech also reported that SpaceX had not responded to its request for comment as of Sunday.
