AI summary
- A Lead Stories fact check found no evidence that Jared Kushner bought .si domain names, and his firm Affinity Partners denied that he owns any.
- Register.si said there were already more than 160,000 .si names before September and that interest from international companies has grown since.
- The registry doesn't allow anonymous registration, and its public WHOIS shows each name's registration date, expiry date, holder and registrar.
- Check WHOIS before you buy any .si name, and treat most .si names as speculation in a small aftermarket.
What the fact check found
On 8 October 2026, an X account called @RetroCoast posted: "BINGO! Jared Kushner owns the domains .si so that is why Trump is trying to rebrand AI to Super Intelligence". It offered a tidy explanation for a strange policy, which is probably why people shared it.
Lead Stories looked into it, and the fact check published on Yahoo doesn't hedge: "there is no evidence that Kushner recently acquired any .si domain names". Kushner's investment firm, Affinity Partners, told Lead Stories in an email on 9 October that "Jared Kushner does not own any .si domain names."
That's the newest development in the .si story, and I think it matters more to buyers than it first looks. Not because of who owns what, but because of what the registry said while answering.
What Register.si told Lead Stories
The .si extension is Slovenia's country-code domain. It's managed by the Academic and Research Network of Slovenia (ARNES), which operates the official registry, Register.si.
In an email on 11 October, Register.si spokesperson Klara Herman gave three useful facts:
- "Before September, there were already more than 160,000 registered .si domain names, representing Slovenian businesses, individuals, organisations and holders of intellectual property rights."
- "Since September, we have seen increasing interest from international companies wishing to associate their online presence with superintelligence."
- "Information about registered domains, including their registration date, expiration date, domain holder and registrar, can be checked through our public WHOIS service."
Lead Stories also noted that Register.si doesn't allow anonymous domain registration, with details in the registry's privacy statement. The registry also publishes an article on .si growth that it updates daily.
Why the rumour doesn't hold up, and what's really driving demand
The real trigger is public. The order titled "Inaugurating the Era of Super Intelligence" was signed on 29 September. According to an ANI report carried by WebIndia, it directs federal departments and agencies to use the terms "Super Intelligence" and "SI" in official correspondence, public communications, policy documents and non-statutory documents.
That's a naming rule for government. A Japanese explainer on note, which cross-referenced the original text, says the order "did not change the definition of the technology or impose new obligations on private companies."
The open question is the definition. Another note writer points out that Executive Order 14434 defines SI as the technology and systems that have been called AI until now. A federal definition is due as draft legislation from the President's Science and Technology Advisor within 60 days, which lands around the end of November.
Politics hasn't settled either. Senator Bernie Sanders has backed a proposal from Michigan Democratic Senate candidate Abdul El-Sayed to temporarily halt development of advanced AI models and data centres until policymakers set new safeguards. Meanwhile Elon Musk replied "Yes, we will make that change" on 5 October about renaming SpaceXAI to SpaceXSI.
So the demand for .si has a public cause, not a secret owner. That's reassuring in one way and sobering in another: if the cause is a government naming rule, the interest can fade if the rule does.
How to check a .si name before you buy
The registry's answer gives you a practical checklist. Because .si names can't be registered anonymously and WHOIS is public, you can verify a lot yourself:
- Check the registration date. If a seller says they've held a name for years, you'll see in WHOIS when it was really registered. A name registered after 29 September is part of the rush. That's fine, but price it accordingly.
- Check the expiration date. Don't pay aftermarket money for a name without knowing when it's due for renewal.
- Check the holder and registrar. Make sure the person selling it is the one who controls it, and use a transfer method you trust.
- Ignore the rumours. A viral claim about who owns .si isn't a reason to buy or sell. This fact check shows how quickly a neat story can turn out to be wrong.
Names from my inventory that pass the basic test
I'd only look at plain words where the .com and .ai are taken or expensive. Four names on my list fit that, and I'll only claim what the data shows:
- aimarket.si at $4,500: the .com is listed at $594,888 and the .ai at $47,995, with 12,100 searches a month.
- aiprompts.si at $5,500: 201,000 searches a month, the .ai listed at $44,500 and the .com held since 2018.
- liedetector.si at $3,000: 60,500 searches a month, the .ai listed at $65,000 and the .com held since 1998. It fits a week when a fact check is the news.
- futurehuman.si at $1,500: 5,400 searches a month, the .ai listed at $290,000 and the .com held since 1999.
Should you buy a .si name because of this?
No, not because of this. A debunked rumour doesn't change the value of any domain. What it does change is how you should buy: check WHOIS, check the holder, and don't trust stories you can't verify.
Be honest with yourself about the market too. Most .si names are speculation, and the aftermarket is small. Register.si says there were more than 160,000 .si names before September, representing Slovenian businesses, individuals and organisations. The new international interest rests on a naming order whose fuller definition isn't due until around the end of November. If the .com of your words is available at a price you can pay, the .com is the better buy.
A .si only makes sense if it passes three questions:
- Are the .com and the .ai taken or expensive? If either is affordable, buy that instead.
- Is it a generic name, not a brand? Plain words like "ai market" are fine. A copy of one company's name, SpaceXSI included, invites a dispute you won't win.
- Do people search for it? If nobody types the phrase, a cheaper extension won't create demand.
If a name clears all three, a .si can be a sensible, low-cost hedge. If it doesn't, I'd walk away, even from my own list.
