A data-driven analysis of the two hottest non-.com extensions in domaining right now โ and what every investor needs to know before buying either.
THE NUMBERS THAT STARTED THIS POST
A tiny Caribbean island of 15,000 people is now funding airport construction, healthcare, and tax cuts from two letters of the alphabet. From $2.9 million in 2018, .ai domain revenues soared to over $93 million in 2025 โ representing nearly half of Anguilla's entire national budget. As of January 2, 2026, registered .ai domains surpassed 1 million โ a tenfold increase from pre-boom levels of around 50,000 in 2020.
Meanwhile, over in the Indian Ocean, a geopolitical dispute between the UK, Mauritius, and the United States is quietly putting a question mark over 1.6 million .io websites โ including those of some of the biggest tech companies in the world.
These two extensions are the most discussed non-.com opportunities in domaining right now. Here is the full picture on both.
THE .AI AFTERMARKET IS ON FIRE
On Afternic, .ai went from not being in the top 20 TLDs by sales value two years ago, to #10 in 2023, to third place in 2024 โ behind only .com and .net. That is not incremental growth. That is a category rewrite.
In 2024, .ai domains claimed 20 spots in the top-100 domain sales list โ up from 9 the year before โ with 13 of those selling for over $100,000 each. Notable confirmed sales: you.ai at $700,000, girlfriend.ai at $250,000, mini.ai at $100,000. Fin.ai reportedly went for $1 million.
These are not flukes. "AI" was the most searched keyword on Sedo in 8 out of 12 months of 2024. End-user demand is structural, not speculative.
The registration boom
Registrations grew 50% in 2022, 230% in 2023, and 300% in 2024. By January 2026, new .ai domains were being registered at a rate of 2,008 per day โ up from 1,318 per day in 2025. The pipeline is not slowing down. Companies like perplexity.ai, claude.ai, x.ai, meta.ai and google.ai choosing the extension as their primary brand address has permanently legitimised it in the eyes of end users and VCs alike.
The infrastructure upgrade
This is one detail most people in the domaining community missed: in January 2025, Anguilla transitioned operational control of its domain registry to Identity Digital โ one of the largest domain infrastructure providers globally โ while retaining domain ownership and revenue share. This is significant. The backend is now institutional-grade. The days of worrying about a small island government handling registry operations are over.
The real risk on .ai (and it isn't what you think)
The risk on .ai is not geopolitical. Anguilla is stable, the registry is now run by Identity Digital, and demand shows no signs of breaking. The real risk is saturation of the mid-tier. Premium one and two-word .ai domains โ think verb.ai, concept.ai, profession.ai โ still have strong end-user demand. But the long-tail is getting crowded fast, and most of those registrations will not renew at premium prices when the AI hype cycle eventually cools. Anguilla's own finance minister publicly cautioned against over-reliance on domain revenue, warning that a new tech fad could shift demand quickly. Smart advice. Domain investors should take it too.
The play: short, memorable, single-concept .ai names. Avoid anything that only makes sense in the context of today's AI headlines.
THE .IO TIME BOMB EVERYONE IS IGNORING
.io was delegated to the British Indian Ocean Territory in 1997. The domain became popular among startups and developers for its association with "input/output" in computing, with GitHub.io and Google I/O helping embed it in tech culture. Today it hosts over 1.6 million websites.
Here is the problem: in October 2024, the United Kingdom and Mauritius announced a political agreement to transfer sovereignty over the Chagos Archipelago to Mauritius, later formalised in a treaty signed on 22 May 2025. The British Indian Ocean Territory โ the entity .io is assigned to โ is in the process of ceasing to exist.
What the rules actually say
According to IANA guidelines, ccTLDs are tied to ISO 3166-1 codes. If the "IO" code were removed following the end of BIOT, a decommissioning process would begin with a transition period of five to ten years. ICANN's own director of communications confirmed on record: "If IO were no longer maintained as a code for this territory, this would trigger a five-year decommissioning process."
ICANN defers to ISO on this. If ISO removes IO from ISO 3166-1, the clock starts. IANA protocol is to notify the ccTLD manager and begin retirement after five years, with a possible extension of another five โ ten years maximum total.
The historical precedent cuts both ways
The optimists point to .su, which has survived over 30 years since the Soviet Union collapsed. The pessimists point to .yu โ Yugoslavia's ccTLD, which remained in use as the country disintegrated into Serbia, Croatia, and others, before ICANN finally retired it in 2010 โ forcing a migration that caused significant operational difficulties for existing domain holders.
.io's situation sits somewhere in between, and nobody can tell you with certainty which path it follows.
The current status: on ice
Here is the update most articles are missing. The UK-Mauritius deal has been shelved indefinitely after the US failed to provide formal approval, with no new ratification bill expected in the near term. The agreement is described as "on ice," though UK officials say they hope to revive it with future US support.
This means the five-year clock has not started yet. But it also means the situation is unresolved and politically volatile โ dependent on US foreign policy priorities that have nothing to do with domain names.
The practical reality for investors
Identity Digital, which administers .io through its UK-based subsidiary Internet Computer Bureau, continues to support the management, reliability and security of the TLD. The registry has every financial incentive to keep .io alive โ it was reportedly a key value driver in Identity Digital's acquisition of Afilias. They will fight to preserve it.
But here is the uncomfortable truth for domain investors: you cannot underwrite a long-term hold on an extension whose ten-year maximum sunset window may begin ticking at any point, triggered by a geopolitical decision in Washington that has nothing to do with tech.
The play on .io: if you are holding premium .io names with strong end-user demand, sell into the current market while sentiment is still broadly positive. If you are buying, price in the uncertainty โ you are accepting political risk that .com holders simply do not have.
THE SIDE-BY-SIDE
THE TAKEAWAY
.ai is not a bubble. It is a structural shift in how AI companies brand themselves, backed by institutional registry infrastructure and documented end-user demand at every price tier. The risk is paying peak prices for mid-tier names that will not find end users once the hype normalises.
.io is not dead. But every domain investor holding .io names should understand exactly what they own: an extension whose future is legally contingent on a sovereignty treaty currently frozen by US foreign policy. That is not a reason to panic. It is a reason to price your exits accordingly.
The market for premium two-letter ccTLDs that accidentally became category identifiers is one of the most interesting in domaining right now. Both .ai and .io got here by luck โ assigned to small territories decades ago and repurposed by tech culture into something nobody planned. The difference is that one of those territories still exists.

THE SIDE-BY-SIDE
| .ai | .io | |
|---|---|---|
| Registry operator | Identity Digital (since Jan 2025) | Identity Digital / Internet Computer Bureau |
| Registrations | 1M+ and growing fast | 1.6M, growth slowing |
| Aftermarket rank | #3 globally by value | Declining |
| Existential risk | Low | Moderate to high (unresolved) |
| End-user demand | Very strong | Strong but cooling |
| Best hold horizon | 3โ7 years | Sell into strength |
| Biggest threat | Mid-tier saturation | Geopolitics |
