Market brief

The .si domain rush of 2026

Published 1 October 2026 · telecoms.si

In short. Once the US government renamed AI "Super Intelligence", Slovenia's .si extension became the SI equivalent of .ai. Registrations jumped about 13x in September 2026, and well-funded superintelligence companies are already paying five figures for .si names.

Timeline

June 2026	Domain press reports growing investor interest in .si as superintelligence labs rise.
22 Sept 2026	At the UN General Assembly, President Trump says AI will be "hereinafter officially called 'Super Intelligence'". .si registrations accelerate.
24 Sept 2026	otherwise.si sells for $18,888.
28 Sept 2026	The .si zone reaches about 219,000 domains, up from roughly 190,000 at the start of the month.

Registration surge

46,066 .si domains registered in September 2026, versus 3,515 in August — about 13 times as many (Register.si).
245,000+ .si domains in total by 1 October 2026.
Interest spiked from 22 September, after the UN speech.
Most new registrations came from domain investors betting that .si names will rise in value as "SI" spreads.

Recent .si sales

recursive.si	$20,000 — bought by Recursive Superintelligence
otherwise.si	$18,888 (24 Sept 2026)
new.si, tiger.si, great.si	€1,200–€3,000 each (investor sales, mid-2026)
military.si	$1,795

The recursive.si sale is the clearest signal: a superintelligence company valued in the billions chose to pay for a .si name, the same way AI companies once moved to .ai.

Where telecoms.si fits

Price: £5,000 plus escrow fees (about $6,700), roughly a third of the documented recursive.si and otherwise.si sales.
Keyword: a whole industry, not a generic word. Telecoms is one of the sectors most transformed by SI (see the 2026 report).
Scarcity: with tens of thousands of .si names registered in September alone, exact industry keywords like this are already taken.

Risks to weigh

Speculative demand. Most 2026 sales were between domain investors; in one month, a single investor accounted for 43% of public .si sales.
Adoption is unproven. The executive order applies to federal agencies only. Leading labs signed the Accord but have not renamed products.
Politics. The rename is politically charged, and its staying power may depend on future administrations.
Registry control. Slovenia's registry sets .si rules and pricing.
