Slovenia’s .si Domain Registrations Surge After Trump’s ‘Super Intelligence’ Order

Slovenia’s .si internet domain is attracting an unusual wave of registrations following a U.S. executive order that directs federal agencies to use “SI” and “Super Intelligence” in place of “AI” and “Artificial Intelligence.”

The surge recalls what happened to Anguilla’s .ai country-code domain as artificial intelligence became a global technology boom. Demand for .ai addresses generated significant revenue for the Caribbean territory as startups and technology companies competed for AI-related web names, a trend The New York Times documented.

.si registrations jump sharply

Slovenia’s domain registry has seen a dramatic increase in demand. Klara Herman, a spokesperson for the country’s official Registry SI, told the BBC that .si purchases rose 2,199% in September, although she cautioned against attributing the entire increase to a single event.

The timing has nevertheless drawn attention. The registry recorded about 11,000 new addresses on September 30, one day after President Donald Trump signed the order, and nearly 13,000 additional .si domains were registered over the following 24 hours. The BBC reported on the sudden demand as interest spread beyond Slovenia.

The September 29 executive order states that executive agencies should use “Super Intelligence” and “SI” in official communications and other non-statutory documents wherever permitted by law. The administration argues that the terminology better reflects the capabilities of modern frontier systems.

U.S. and Indian buyers drive demand

Demand is not uniform across domain providers. GoDaddy does not currently host .si domains, while Wix said it had not seen a meaningful increase immediately after the order.

Hostinger, however, reported a sharp rise. The company said .si had become its second most popular domain extension behind .com, with roughly 4,300 registrations on September 30 and another 5,400 on October 1. More than half of those buyers were reportedly located in the United States and India.

Only about 3% of the .si names registered through Hostinger were explicitly related to artificial intelligence or superintelligence, suggesting that much of the activity may be speculative or driven by buyers securing short names before prices potentially rise.

Some founders are already treating .si addresses as digital assets. Buyers have begun securing versions of their company names as a defensive measure, while others are purchasing domains in the hope that they could later be resold if “SI” develops the same branding value that “AI” gained during the previous domain boom.

.si is unlikely to replicate Anguilla's .ai windfall

The White House order says today’s frontier systems increasingly represent “not merely artificial intelligence, but a new era of Super Intelligence,” giving the abbreviation an official federal use that did not previously exist. The order applies the new terminology across the executive branch, subject to existing law.

Even if the new label catches on, Slovenia may not experience the same economic impact Anguilla received from .ai. Hostinger’s head of domains, Klaudijus Januitis, noted that .si registrations are considerably cheaper, while revenue goes to the registry rather than directly becoming a major source of government income.

For now, .si appears to be benefiting from a combination of speculation, branding interest and the sudden prominence of “super intelligence.” Whether that becomes a lasting domain trend will depend on how widely the SI terminology spreads beyond the U.S. government.
