Trump’s ‘Super Intelligence’ Rebrand Sends Slovenia’s .si Domains Past 20,000 in a Day

Slovenia’s national domain registry counted 20,276 new .si registrations in the 24 hours to Monday afternoon, a burst of activity that turned an obscure European country-code extension into one of the year’s most traded digital assets. The trigger came from Washington: .si maps neatly onto “Super Intelligence,” the label President Donald Trump has told US federal agencies to adopt in place of “artificial intelligence.”

For a registry that normally sees fewer than 2,000 sign-ups a month, the spike is a striking demonstration of how a political rebrand can reshape a technical market overnight.

• A single day, 20,276 domains: Slovenia’s registry logged the surge in just 24 hours, against fewer than 2,000 for the whole of August.
• The rename is official policy: Trump argued at the UN that “artificial” made the technology sound fake, then signed an executive order requiring agencies to use “Super Intelligence” and “SI.”
• Speculators are driving it: More than half of buyers are in the US and India, yet only about 3% of the registered names are explicitly AI-related.

From the UN podium to the executive order

Trump told the UN General Assembly on 22 September that the word “artificial” made the technology “sound fake.” The White House text of the speech declared AI “hereinafter officially called ‘Super Intelligence.'” On 29 September he signed an executive order titled Inaugurating the Era of Super Intelligence, instructing federal agencies to use both the full term and the abbreviation SI in official communications, at a White House technology summit billed as the Super Intelligence Luncheon.

The domain data followed within hours. Register.si recorded 11,000 new .si addresses on 30 September, the day after the order. Security firm Netcraft, tracking the phenomenon more granularly, counted 4,794 registrations in the 24 hours after the UN speech, rising to 13,603 on 1 October. Over the past month the registry added 46,066 new .si names, lifting the cumulative total to 298,682.

Register.si spokeswoman Klara Herman described the late-September activity as “unprecedented,” while staying cautious about crediting the entire surge to the US announcement. Anyone can register a .si address regardless of residency, and the registry says it will keep publishing fresh data as the trend develops.

Who is buying, and why the .ai playbook may not repeat

Web host Hostinger, one of the busiest registrars during the boom, says .si is now its second most popular extension after .com. More than half of its .si buyers sit in the US and India, and the economics are easy to grasp: a .si name costs roughly $12 a year, against about $90 for .ai, which carries a two-year commitment. The catch lies in the composition of demand — only around 3% of names registered are explicitly about AI. The rest are ordinary words and brandable strings that buyers hope to flip.

Resale behaviour confirms that intent. More than half of the .si names bought early through registrar Dynadot went straight onto its aftermarket. Netcraft separately identified 87 .com domains pairing well-known brands with the word “superintelligence,” all registered before the executive order and all offered for resale at around $20,000 each. One premium name, AI.si, is listed at nearly $700,000.

“For Anguilla, .ai became a second economy. For Slovenia, .si is a nice bonus.”

That assessment comes from Klaudijus Januitis, head of domains at Hostinger.

Musk joins in, but Slovenia’s upside stays modest

Add Elon Musk to the trend: he confirmed on X that his AI company would drop the SpaceXAI name in favour of SpaceXSI, telling a user, “Yes, we will make that change.” He had previously written, “No more AI. SI. It’s better.” The company had already been renamed once this year, after xAI was absorbed by SpaceX in a $250 million acquisition.

The obvious comparison is Anguilla, whose .ai extension generated more than $85 million last year from over a million registrations. Slovenia, with roughly 2 million inhabitants and a GDP of about €68 billion, will not see a comparable windfall. Register.si, run by the Academic and Research Network of Slovenia, charges registrars only about $11 per domain, meaning September’s surge produced something in the order of $300,000 at wholesale level. Trump has also stood up a Super Intelligence Force to push the terminology, led by National Intelligence Director Jay Clayton.

Whether the boom endures depends less on domain economics than on whether “Super Intelligence” escapes the realm of executive orders and enters corporate vocabulary. Computer scientist John McCarthy coined “artificial intelligence” in 1955, and seven decades later the industry still runs on his phrase. Until US startups, cloud providers and investors start writing SI on their pitch decks, Slovenia’s registry is monetising a fad rather than an infrastructure shift — a lucrative one nonetheless. Netcraft reports no rise in phishing tied to the rename so far, and Register.si intends to keep publishing numbers, making the coming months of registration data an unusually clean referendum on whether a rebrand invented in Washington actually travels.
