The Slovenian national extension, .si, recorded 46,066 new domains in September 2026, versus 3,515 in August.
This striking surge coincides with statements by Donald Trump, who has expressed a desire to replace the expression “Artificial Intelligence” with “Super Intelligence.”
On September 22, before the United Nations General Assembly, Trump proposed giving preference to this term over Artificial Intelligence, arguing that the word artificial is unflattering. A week later, on September 29, he signed an executive order mandating that U.S. federal agencies adopt this new terminology in their communications.
.si: A national extension since 1992
Launched on April 1, 1992 with its official delegation to IANA, the .si represents the cornerstone of Slovenia’s online identity. Its management and the resilience of its DNS infrastructure are ensured by the Academic and Research Network of Slovenia (ARNES), guaranteeing a solid local foothold.
The extension is not restricted to Slovenian actors. Registration rules permit individuals as well as legal entities, with no nationality or residence condition required.
Allocation operates on a first-come, first-served basis, subject to adherence to the registry’s rules. A domain name must be between 2 and 63 characters long. It cannot start or end with a hyphen, nor contain two consecutive hyphens in the third and fourth positions.
Registration is possible for a term of one to five years, with renewal.
A wholesale price of €10 per year
The registry lists a price of €10 excluding tax for the registration or annual renewal of a domain. This amount, in effect since January 1, 2023, reflects the price charged to registrars, and not necessarily the amount paid by the end customer.
ARNES specifies that it does not intervene in setting the prices charged by intermediaries. The cost for a holder thus depends on the registrar chosen and any associated services.
The figures from the Slovenian registry underscore the scale of the phenomenon.
Register.si logged 46 066 new domains in September, compared with 3 515 in August, roughly thirteen times higher.
On September 23, the day after Trump’s speech, the registry already showed 4,794 new registrations in the previous 24 hours. After the decree was signed, this pace exceeded 13,000 daily registrations.
However, these data do not by themselves prove that the entire increase is due to the American President. Growth had begun before the decree, and the arrival of new registrars also contributed to the acceleration.
A rush also driven by speculation
Moreover, the surge in requests does not necessarily reflect widespread adoption of .si by AI companies. Some buyers are seeking to reserve short or evocative names in the hope of reselling them if the term Super Intelligence becomes ingrained in professional vocabulary.
Observations by Netcraft, a company specializing in monitoring Internet activity, bolster this hypothesis.
In the first wave, more than half of the .si names registered on the Dynadot platform during the studied period were put up for sale on its secondary market. This is a sample tied to a single registrar and not a representative measure of all buyers.
The phenomenon mirrors that of .ai, Anguilla’s national extension, which has become a standard domain name for AI companies.
