.cas
Is .cas a real TLD? Who’s applying to run it?
.cas is not contested. One application for it is on ICANN’s Reveal Day list, as of 7 October 2026. It is SUVAN NET LLC.
A short three-letter string with no obvious meaning to most buyers; niche acronym appeal, thin demand, little resale value.
organizations and brands that already use "CAS" as an acronym or short name, plus a small set of speculators chasing three-letter strings
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 almost exactly: a three-letter string with no settled meaning that several unrelated readings can claim, run as an open namespace by an operator whose own name is not those letters, so demand rests on buyers projecting a meaning onto the letters rather than on any one group treating it as their natural home.
The same bet that brevity and a blank string can sell registrations without any category meaning behind them, differing only in ambition — .xyz is pitched blank to everyone, while a .cas-type string is blank but acronym-shaped, so it courts the narrower set of holders of those letters.
Also a consonant-cluster acronym that means nothing to a general buyer and must be given a meaning by the registry's positioning, with the same dependence on a handful of organizations already using those initials plus short-string speculators.
What a .cas domain is
.cas is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under Brand. One application for it is on ICANN’s Reveal Day list.
Is the .cas domain extension real yet?
.cas is not yet a domain extension you can register: nothing resolves under it, and no registrar sells names in it. It is a string applicants have put forward in the ICANN 2026 new gTLD round, the process that decides whether it becomes one.
When can you buy a .cas domain?
You can’t yet. ICANN publishes every applied-for string on Reveal Day, 7 October 2026 at 18:00 UTC. A .cas name can only be registered after that, once the string is delegated and its registry opens. Last round's closest parallel to .cas was .icu, delegated on 2 May 2015.
Is .cas a real TLD?
Not yet. .cas is not in the DNS root, so nothing resolves under it. It’s here because .cas is on ICANN’s Reveal Day list of applied-for strings. Every entry on this page links to its source.

- Band chosen: 10-29 (vanity/narrow). .cas is a three-letter string that reads as an acronym rather than a word: it is used by several unrelated bodies and concepts (a chemical-information registry, a sports arbitration body, an authentication protocol, content-addressed storage, and various company abbreviations), so no single buyer group would pick it as a default identity. By analogy (flagged as analogy), short new gTLDs lacking a clear dictionary meaning have tended to attract low, price-driven registrations and have rarely become a serious primary identity, which is why this is not in the 30-49 band: there is no category where .cas registrations would plausibly happen at volume on utility rather than novelty. It is not in the 1-9 band because three-letter strings do carry modest brand and abbreviation demand, and a handful of organizations that already go by CAS could adopt matching addresses. The single application on the record is from SUVAN NET LLC (status confirmed, no category tag recorded); the operator's distribution plan and pricing are unknown, which matters for whether even acronym-driven demand materializes. Main market uncertainty: whether the registry positions .cas toward one concrete meaning (for example, a vertical or a language-specific word) that could give it a niche identity, versus leaving it as an undefined acronym string.
