On September 29, President Trump signed an executive order mandating that artificial intelligence be renamed “Super Intelligence” within the executive branch, which formalized what he first mentioned at a speech to the UN on September 22. This rename put a spotlight on a two-letter web address owned by Slovenia. Almost 20% of all .si domains were registered in the last month.
A top-level domain is everything after the dot (.com, .edu, .gov). Every country gets its own two-letter domain (.us, .ca, .uk, .si). These are called ccTLDs (country-code top-level domains). Each TLD is run by a registry, which manages and maintains the master database of all domain names. Industry leaders are Verisign, which runs .com and .net; Identity Digital, which manages .ai, newly acquired .us, and many generic TLDs. Slovenia’s ccTLD is managed by Register.si. On the other side of the domain business, registrars like GoDaddy and Namecheap sell them to customers.
For many countries, these ccTLDs remain for internal use: government websites, funded programs, resources for citizens. However, some of these TLDs are purchased for what the extension spells. Popular examples are .tv (Tuvalu), .io (British Indian Ocean Territory), .ai (Anguilla). When artificial intelligence started gaining traction, Anguilla was one of the most unexpected beneficiaries. In 2022 there were just 144,000 registered .ai domains, which then shot up to over 1,000,000 by early 2026, raking in $85.3M in revenue for the small Caribbean island in 2025. Growth hasn’t slowed: .ai has added about 450,000 domains so far this year.
This raises the question for the recently on-the-radar “Super Intelligence” domain, .si: Will start-ups adopt the domain? According to a Domain Name Wire article from October 1, Leanne Mac, who tracks the domains that startups use when launching on ProductHunt, found no .si launches in the past 30 days. Compare that to .ai, which had fifty launches on a single day. In the domain industry, new registrations are called “creates.” The data suggests most .si creates are coming from domain investors.
These domain investors buy domains for low prices based on trends, to sell to an end user later. The investor must pay the yearly renewal for each domain in their portfolio, a standard $12/year for a .si domain, but they capitalize on favorable phrases, like when ai.com was bought for $70M in 2025 by Crypto.com’s CEO. A record-breaking sale for .ai was Bot.ai for $1.2M in February 2026. Also, a domain broker is listing AI.si for $699,995. However, that’s an ask, not a sale.
There are a few early signs from actual companies. Recursive, an artificial intelligence startup founded in 2026 that focuses on recursive self-improvement of AI, bought Recursive.si, though it redirects to their main site, Recursive.com. These are important details because the key to .ai’s rise in the domain world was companies building real products on it.
If .si does take off, who stands to benefit? Slovenia has over 100 times Anguilla’s population, so .si won’t reshape its budget the same way. But Anguilla shows what’s possible. The two-letter domain brings in close to half of the Anguillan government revenue, funding an airport expansion, a vocational tech center at the high school, and more.
I got to see Anguilla firsthand this summer through my Identity Digital internship when I traveled there to help run a robotics camp for local students. This was the return trip, after Anguillan students and educators came to Blacksburg earlier in the summer. Anguilla may be known for its beaches, but the students I spent most of my time with showed a lot of interest in STEM. Domain revenue is helping invest in students like them.
So, is Slovenia’s domain the next .ai? For now, .si creates look like speculation. If startups start launching on the “Super Intelligence” domain, and if other governments adopt this term, domain investors, and Slovenia, might cash in. The renewals a year from now will tell the real story. I’ll be watching.
