.dex
Is .dex a real TLD? Who’s applying to run it?
Nobody has applied for .dex in its own right, as of 7 October 2026. XYZ named .dex as a backup string for its .cmo application. ICANN deactivated it, because another applicant applied for the same string or named it as a backup. Suffix Inc. named .dex as a backup string for its .universe application. ICANN deactivated it, because another applicant applied for the same string or named it as a backup.
A short crypto-flavored ending that a decentralized exchange might pick, but most serious projects would still choose a mainstream domain.

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: an insider initialism for a trading venue/instrument that only its own market can read, sold as the front-door identity to the operators and traders who deal in it, and it pays off only if the jargon outlives the wave that produced it.
Same underlying wager on the venue word itself as primary identity for anyone running a marketplace where assets change hands, but it is a plain unowned English noun open to every registrant type, where the target is a compressed insider form that carries a technical precondition about how the venue is built.
Same bet on an abbreviated market-category label becoming the address for the venues, brokers and speculation-adjacent content in that market, differing mainly in that its market was decades old and institutionally settled rather than a few years old and still arguing about what it is.
What a .dex domain is
.dex is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under Crypto. Nobody has applied for .dex in its own right. It is named on ICANN’s list as part of an application for another string.
Is the .dex domain extension real yet?
.dex 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 .dex domain?
You can’t yet. ICANN publishes every applied-for string on Reveal Day, 7 October 2026 at 18:00 UTC. A .dex name can only be registered after that, once the string is delegated and its registry opens. Last round's closest parallel to .dex was .cfd, delegated on 13 March 2015.
Is .dex a real TLD?
Not yet. .dex is not in the DNS root, so nothing resolves under it. It’s here because ICANN’s list names .dex as part of an application for another string. Every entry on this page links to its source.

- Band chosen: 30-49, usable but limited. The string reads instantly as 'decentralized exchange' inside crypto and secondarily as 'index' or 'dexterity' (gaming, developer tooling), so there is a genuine buyer group and a three-letter string is easy to say and type. It is not in the 50-69 band because, by analogy with how crypto projects have historically chosen DNS identities, DeFi teams have tended to settle on mainstream or generalist endings (.com, .io, .xyz, .finance-style keyword TLDs) rather than a category-specific DNS TLD, and the blockchain-native naming systems absorb much of the 'crypto identity' demand outside the DNS entirely (analogy, not a verified count). Primary-identity adoption on .dex would therefore need explaining, and the aftermarket would likely be thin and event-driven, tracking crypto market cycles rather than steady demand. It is not in the 10-29 band because the word is a real, in-use category noun with ongoing product launches behind it, not a joke or vanity string, and a short string with a clear meaning can plausibly sustain some serious primary-identity use over 5 years. Operator facts on the record are neutral: two standard applications exist, both recorded as deactivated and both filed as replacement strings for other primary applications; contention count on the record is 0. These facts say nothing about market demand and are used only to note that no launch backer or pricing posture is known. Main market uncertainty: whether DeFi and exchange projects adopt any DNS-level crypto TLD as a primary identity at all over the next 5 years, versus continuing to prefer generalist endings and on-chain naming; a second uncertainty is regulatory pressure on decentralized exchanges narrowing the buyer pool. Specific registration figures, pricing, and analogous-TLD outcomes are unknown here and I have not asserted any.
