Musk Says SpaceXAI Will Be Renamed SpaceXSI, Days After Trump Ordered Agencies to Say ‘Super Intelligence’

Elon Musk says SpaceXAI, the SpaceX division that makes Grok, will be renamed SpaceXSI. He confirmed it on X on Sunday, October 4, 2026, replying “Yes, we will make that change” after a user asked whether SpaceXAI could become SpaceXSI.

The swap from AI to SI mirrors President Donald Trump’s September 29 executive order, which tells federal agencies to say “Super Intelligence” instead of “Artificial Intelligence.” About half an hour before the rename reply, Musk posted three lines: “No more AI / SI / It’s better.” Three minutes after it, he added that “SpaceX is a super intelligence company.”

That is the whole announcement so far. There is no press release, no timeline, no filing, and no word on Grok, the API or the @SpaceXAI account. Here is what is confirmed, what is not, and why the order Musk is echoing does not actually apply to companies at all.

What Musk actually posted

All three posts went up early Sunday morning U.S. Eastern time, according to the timestamps X returns for them. By Monday, X’s public metrics showed the “No more AI” post with more than 14 million impressions and roughly 128,000 likes, far more reach than the rename reply itself.

So the rename was not a planned launch. It was a yes to a fan’s question, given minutes after a slogan. That does not make it less likely to happen, since Musk controls the company, but it explains why nobody can say yet what changes and when.

What Trump’s executive order requires, and what it does not

The order is Executive Order 14434, “Inaugurating the Era of Super Intelligence”, signed September 29 and printed in the Federal Register on October 2. Section 2 tells executive departments and agencies to use “Super Intelligence” and “SI” in official correspondence, public communications, websites, reports, policy documents and other non-statutory documents.

The same section says nothing requires agencies to rewrite previously issued regulations, contracts, grants or historical documents. Section 3 defines SI as whatever the existing statutory definition of artificial intelligence (15 U.S.C. 9401(3)) already covers, so the legal meaning does not change. The Assistant to the President for Science and Technology has 60 days to propose legislative language for a new federal definition.

The order’s policy section and the White House fact sheet go further in tone, saying the executive branch will no longer acknowledge the terms AI or Artificial Intelligence. But the order binds the executive branch only. No company, including SpaceX, is required to rename anything. Fox Business framed Musk’s move as following a Trump directive; it is better described as a voluntary match.

We covered the accord signed the same day, with Musk among the signatories, in our report on the White House Super Intelligence accord.

California went the other way

One day after Trump’s order, California Gov. Gavin Newsom signed Executive Order N-10-26, requiring state agencies under his authority to keep calling the technology “artificial intelligence” or AI. POLITICO quoted Newsom saying “Super intelligence is clearly not coming from the White House,” adding that this is why California continues to lead.

Forbes reports the California order calls the federal rebrand a bid to distract from an “impotent and craven failure” to address documented safety and security risks. So the U.S. now has two government vocabularies for the same technology, one federal and one Californian, and Musk’s AI business is picking a side in its own name.

The third name since February

SpaceXSI would be the business’s third identity in about eight months. Here is the sequence, with sources.

One correction to some coverage: Fox Business wrote that SpaceXAI was created in July “after SpaceX acquired xAI in a $1.25 trillion deal.” The acquisition was announced in February. The USD 1.25 trillion figure is the combined value Reuters reported at the time, not a price paid in July.

Teslarati reports the AI division now houses Grok, the X platform, the Colossus training clusters in Memphis and Cursor. A name change would touch all of that branding, which is why the missing details matter.

Confirmed vs. not confirmed

What it means for developers and businesses in the US, Canada, Australia and India

For anyone building on Grok, nothing changes today. SpaceXAI’s most recent posts before the rename talk were product news: Grok 4.7 arriving on Google’s Gemini Enterprise Agent Platform on October 1, and a Ramp Router promotion offering Grok 4.7 at 50% off until October 6. There has been no notice about model names, endpoints or invoices.

U.S. federal contractors are the group most likely to feel the vocabulary shift. Expect “SI” to start showing up in agency requests, guidance and reports. Because the order ties SI to the existing statutory AI definition, the scope of what is being bought does not change, only the label on it.

Canada, Australia and India are not covered. Their governments, regulators and procurement documents still say AI, and nothing in a U.S. executive order changes that. Indian outlets such as the Indian Express are already explaining the term to readers, which suggests the confusion will travel even if the rule does not. In the U.S., Google Trends on Monday listed “spcx stock price” among trending searches, with the rename story attached.

The skeptical read

Renaming a product does not change what it can do. “Superintelligence” has long meant hypothetical systems that outperform humans at nearly everything, a concept popularized by Nick Bostrom’s 2014 book. Applying it to today’s chatbots and coding agents is a marketing choice, and a politically aligned one.

Musk is not hiding that. Teslarati reports he even caught himself at the White House event: “I think it is worth highlighting the positive benefits of A.I. … S.I., pardon me.” Other CEOs have not followed. OpenAI’s Sam Altman still says AI in public, including in his recent POLITICO interview.

There is also a cost to churn. Three names in eight months is a lot for enterprise buyers, partners and developers to track, especially when the newest one arrives as a reply to a fan account. The administration’s own SI push now has a policy arm, too: the Super Intelligence Force led by Jay Clayton. Whether “SI” sticks outside Washington and Musk’s companies is a separate question that a name change cannot answer.

FAQ

Is SpaceXAI officially called SpaceXSI now?

Not yet. Musk said the change will happen, but there was no formal announcement, timeline or filing as of October 5, and the company’s X account still used the SpaceXAI name.

Does Trump’s order force companies to stop saying AI?

No. Executive Order 14434 applies to federal executive departments and agencies. It does not require private companies to change names, and it does not require agencies to rewrite past regulations, contracts or grants.

Will Grok be renamed?

Unknown. Musk did not mention Grok, and SpaceXAI has not said whether product or model names will change.

Do developers using the Grok API need to do anything?

No action is needed right now. No changes to endpoints, model names or billing have been announced. Watch the official docs and the @SpaceXAI account for any notice.

Does the SI rule apply in Canada, Australia or India?

No. It is a U.S. federal executive order. Governments and businesses elsewhere are unaffected, though they may see the term in U.S. government documents and vendor marketing.
