Demand for .si has spread from Slovenia to the rest of the world in a matter of weeks. AI companies want the name that matches their .ai, brand owners want to secure theirs before someone else does, and investors are buying short names in bulk.
Many go to their hosting provider, MSP or agency first, with two questions: should we register .si, and who can set it up? In this article, we look at:
- What the SI order changed
- Why .si demand can turn into years of renewals
- Three .si services you can sell
- How to protect your margin and your clients
The SI order gives you a new reason to talk domains with every client
On 29 September 2026, the US government made “super intelligence”, or SI, its official term for AI in federal communications. Slovenia’s country code uses the same two letters, in the same way Anguilla’s .ai matched “AI”, and new .si registrations rose from 3,515 in August to 46,066 in September.
The executive order “Inaugurating the Era of Super Intelligence” tells US federal agencies to use “SI” and “super intelligence” in official communications. It covers only the US federal government, so companies can keep using “AI”. Even so, news of the order put the letters SI in front of business owners, and many now want a matching domain. Slovenia’s registry felt that demand first.
Slovenia’s ccTLD has gone global, and global ccTLDs bring years of renewal revenue
A ccTLD is a country-code top-level domain, such as .de for Germany or .si for Slovenia. Slovenia’s Academic and Research Network runs Register.si, and for most of its history the domain served Slovenian entrepreneurs and organizations.
That changed after the executive order in Washington DC. Register.si’s domain count grew by more than a fifth in just over a week, and the registry could accept buyers from any country because .si has an open registration policy: anyone, anywhere can register a .si name without a Slovenian address or company. Many ccTLDs ask for a local presence, so this open policy is what turns a national domain into a global product your customers can buy.
Anguilla’s .ai followed the same path. It began as the country code of a small Caribbean territory, and AI companies turned it into a global address. Domain fees now bring in almost half of Anguilla’s government revenue, according to Premier Cora Richardson Hodge.
Slovenia’s position is different. Register.si charges registrars a flat fee per name, each registrar sets its own end price, and Slovenia has a far larger economy, so .si plays a much smaller role in its budget. For resellers, the more useful lesson from .ai is renewals: about 90% of .ai names renew after two years, according to the IMF. Those renewals start with the questions your clients ask today.
Your clients will ask you about Superintelligence .si domain .si, so have a clear recommendation ready
Register.si, the registry that runs .si, has advised businesses to register their brand and company names as Superintelligence .si domains as soon as possible. Many of your clients will read this in the news, and because you manage their domains, they will ask you whether they need a .si too.
Two groups are likely to ask first. Clients with registered trademarks want to secure their names before someone else holds them. AI and SaaS companies with a .ai or .com address want the matching .si, so their brand looks the same across extensions. Netcraft already counts more than 44,000 names that exist in both .si and .ai, and our recent .si and .ai comparison covers how the two extensions differ.
Each of these requests is a chance to sell a service that renews every year, and three services fit .si well.
Three .si services that add recurring revenue to every client account
You can package .si into three services that renew every year: defensive .si registration for client brands, .si bundled with .ai and .com for AI launches, and lookalike monitoring as part of a .si brand protection retainer.
Each one fits the domain portfolio management work you already do:
- Defensive .si for client brands: start with each client’s core brands and company name, which keeps costs low.
- .si with .ai and .com for AI launches: offer the .si alongside the .ai and .com in one package, so no one else can claim the matching name.
- Lookalike monitoring: watch for new domains that copy a client’s brand with a small spelling change, and act early.
More .si names in your clients’ portfolios also mean more work for your abuse desk and your renewal process, so plan for both from the start.
Protect client trust and renewal revenue by planning for .si abuse now
In research from 24 September to 1 October 2026, Netcraft found a low level of fraud on .si and no rise in phishing linked to the rename. It expects criminals to take more interest if “SI” becomes a more trusted term. One risk stands out: “s” sits next to “a”, so a .si name is one typo away from its .ai version. Criminals can register these lookalikes, a tactic called typosquatting, to copy legitimate AI sites.
Speculation also affects renewals. Netcraft found that buyers put about 52% of the Superintelligence .si domain names they bought at one registrar between 19 and 22 September up for resale. Some investors will let unsold names expire, so build a lower year-two renewal rate into your forecasts and set up renewal reminders early.
If someone else holds a client’s .si name, the dispute goes through Register.si’s own process, so point them to the registry’s rules first. Clear processes protect your margin, and so does the price you pay for every name you sell.
Keep your .si margin intact with cost-plus Membership pricing
When a domain trends, more registrars add it and compete on price. Providers that pay full price for each name lose margin on every sale.
Openprovider Membership gives you cost-plus access to every TLD we are accredited for, including .si, with plans from $4.99 a year, so you can set your own margin on top.
Until 30 November 2026, new resellers can register up to 5 .si for €8.39 each in the first year, after verification. After that, every .si renews at €10.29 a year (€10 for Members), so year two stays predictable.
With the economics in place, getting started takes three steps.
Start earning from .si in three steps
First, compare each client’s brands and company names against .si, and list the core names still free. Next, run that list through our bulk check, which searches up to 500 .si names at once, and register the names your clients approve in a single order. Finally, add .si to the storefront your customers already use, through our WHMCS module or the Openprovider API, which you can test first in a free sandbox, a test environment that never touches live domains.
The providers who answer client questions about .si first become the ones they trust with the rest of their portfolio. Compare Membership plans to get .si at registry cost prices, or register your .si domains while our first-year offer runs until 30 November 2026.
Frequently asked questions (FAQ)
What does SI stand for?
SI stands for “super intelligence”. On 29 September 2026, a US executive order told federal agencies to use “SI” and “super intelligence” in place of “AI” in official communications. SI is also Slovenia’s country code, which is why demand for .si grew so quickly.
Who runs the Superintelligence .si domain ?
Slovenia’s Academic and Research Network runs Register.si, the registry behind .si. Anyone, anywhere can register a .si name without a Slovenian address or company. Register.si charges registrars a flat fee per name, and each registrar sets its own end price.
Should agencies register .si for clients?
For clients with registered brands, yes. Register.si advises brand owners to secure their .si as soon as possible. Start with each client’s core brands, and add .si to new AI launches alongside .ai and .com, so no one else can claim the matching name.
Is .si safe from abuse?
Netcraft reports low fraud on .si so far. Because “s” sits next to “a” on the keyboard, criminals could register .si lookalikes of .ai sites, a tactic called typosquatting. Brand owners with a .ai domain can register the matching .si, and providers can monitor client brands for new lookalikes.
