Five days after President Trump signed an executive order telling federal agencies to stop using “Artificial Intelligence” in official communications, Elon Musk posted on X: “No more AI. SI It’s better.” He then said SpaceXAI would be renamed SpaceXSI.
At the time of reporting, SpaceXAI’s X account reflected no such change. No timeline, legal filing, or product-level update had been confirmed, according to Reuters.
What Trump’s Order Actually Does
The directive covers executive-branch communications, not the private sector.
Trump signed the executive order titled “Inaugurating the Era of Super Intelligence” on September 29, 2026. It directs federal departments and agencies to substitute “Super Intelligence” and “SI” for “Artificial Intelligence” and “AI” across official websites, reports, correspondence, and other non-statutory documents.
Critically, the order does not require private companies to rename products, divisions, or corporate entities. Existing regulations, contracts, and grants are also preserved; legal language already in place stays intact. For context on how AI age laws have intersected with industry policy, separate regulatory efforts have shaped the broader landscape.
The order defines “Super Intelligence” as a replacement label, not a new technical category. It covers the same technologies already defined under the existing statutory definition of artificial intelligence.
Trump has previously argued that the word “artificial” makes the technology sound fake, per CNBC’s coverage of the order. That rationale is political framing, not a technical distinction established by the order itself.
Three Names in Under a Year
SpaceXSI would be the unit’s third reported identity since the February acquisition.
SpaceX reportedly acquired xAI in February 2026. By July, the AI business had completed a reported rebrand to SpaceXAI, including a new logo and updated X account. Barely three months later, Musk is signaling another identity shift.
When an X user asked whether the SpaceXAI handle could become SpaceXSI, Musk replied: “Yes, we will make that change.” (Source: @elonmusk, October 4, 2026.)
That rapid sequence could create a practical problem for anyone tracking xAI’s products. Customers, developers, and Grok users may have three names to reconcile across a single year.
“Yes, we will make that change.” Elon Musk, @elonmusk, October 4, 2026, responding to a user asking whether SpaceXAI would be renamed SpaceXSI.
A Terminology Gap Worth Noting
In technical research, “superintelligence” refers to something considerably more specific than current AI systems.
Researchers commonly use “superintelligence” to describe a hypothetical system that exceeds human cognitive performance across all tasks. That is not how Trump’s order uses the term. The order applies “Super Intelligence” as a broad substitute for AI generally, covering the full statutory scope of existing systems. Readers interested in practical applications can explore AI-powered websites that demonstrate what current systems can already do.
Musk’s proposed name change does not establish that SpaceX’s systems have reached any new capability threshold. It is, based on available evidence, a branding and terminology decision.
What to Watch
Whether SpaceXAI updates its website, X handles, and product interfaces will be the clearest signal that this post is becoming an actual rebrand. It is also worth watching whether Grok surfaces under the SpaceXSI identity, and whether other private companies begin adopting “SI” branding in response to the federal terminology shift.
