.idk
Is .idk a real TLD? Who’s applying to run it?
Nobody has applied for .idk in its own right, as of 7 October 2026. Suffix Inc. named .idk as the replacement string of its .future application.
A slang joke ending for memes and one-off fun sites; few serious projects would make it their main address.
meme-makers, humor sites, and individuals wanting a shrug-of-a-name address for side projects and jokes, with occasional low-cost speculative buys
No applications recorded for this TLD yet.
The 2012 applications making the most similar bet. Chosen by AI from every string in that round, without being told what happened to any of them.
Same bet exactly: a chat-born initialism that everyone already types and nobody owns, sold on expressive/novelty value to people registering a joke, a reaction, or a throwaway side project rather than putting a business identity on it.
Also a texting initialism whose whole value is the attitude it carries, so it lives or dies on the same premise as .idk — that casual internet speech can carry a namespace even though no serious brand will anchor to it.
The same three-letter shorthand-everyone-knows bet, but aimed at a utilitarian job (an informational or notice page) rather than a punchline, so the buyer is plausibly an organization instead of only a joker.
What a .idk domain is
.idk is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under Culture. Nobody has applied for .idk in its own right. It is named on ICANN’s list as part of an application for another string.
Is the .idk domain extension real yet?
.idk is not yet a domain extension you can register: nothing resolves under it, and no registrar sells names in it. Nobody has applied for it on the public record; the ICANN 2026 new gTLD round is the process that would decide whether it becomes one.
When can you buy a .idk domain?
You can’t yet. ICANN publishes every applied-for string on Reveal Day, 7 October 2026 at 18:00 UTC. A .idk name can only be registered after that, once the string is delegated and its registry opens. Last round's closest parallel to .idk was .lol, delegated on 2 May 2015.
Is .idk a real TLD?
Not yet. .idk is not in the DNS root, so nothing resolves under it. It’s here because ICANN’s list names .idk as part of an application for another string. Every entry on this page links to its source.

- Band chosen: 10-29 (vanity/joke/narrow). ".idk" is internet shorthand for "I don't know", which makes it a mood or punchline rather than a category, place, or industry. Its closest analogues are the slang and exclamation TLDs such as .lol and .wtf (analogy, no figures asserted): those have drawn registrations largely on registrar promotions and novelty, produced memorable joke sites and domain hacks, and seldom became the primary identity of a sustained business or organization; their aftermarkets are thin and event-driven. On the record this is a replacement string for a standard (non-brand, non-community, non-geographic) application by Suffix Inc., with no contention noted and no category tag, which neutrally suggests a general-availability offering aimed at a casual audience. It is not in the 30-49 band because volume on this string would depend on deep promotional pricing rather than any durable use case, the brand signal is flippant by design, and even the best-fit registrant (a humor brand or meme site) gains little credibility from the ending. It is not in the 1-9 band because a real if shallow market exists: slang TLDs do get registered and used for jokes, parody, and personal sites, and the phrase is widely understood across English-speaking internet culture. Main market uncertainty over the next 5 years: whether registrar channel pricing and placement turn it into a cheap-volume string the way some slang TLDs have been positioned (analogy), or whether it sits unpromoted with negligible registrations; either outcome keeps it inside this band but moves it within it.
