.quantum
Is .quantum a real TLD? Who’s applying to run it?
.quantum is contested: 2 applicants have said publicly that they applied to run it, as of 27 August 2026. They are Radix and Link Freedom Group.
A niche address for quantum-tech startups; strong futuristic branding, but a small buyer pool that mostly defaults to .com or .ai.
quantum computing and deep-tech startups, research labs and photonics/sensing ventures, plus tech brands that use 'quantum' as a marketing word and want a matching suffix.
In LFG's published list of 300+ strings submitted before the ICANN window closed on 2026-08-12. Their catalog tagline: “Where the impossible becomes possible.”
One of 46 ICANN 2026-round applications Radix announced on its own applications page. Radix states it intends to build and operate each TLD it wins.
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: the frontier-computing buzzword of its moment turned into an open generic namespace, wagering that a paradigm-shift technology term pulls primary identity from vendors, labs and consultancies who want to claim the paradigm itself.
Same bet: an emerging deep-tech field noun whose registrant pool is a narrow, well-capitalized set of firms that brand on the discipline, so the value case rests on credibility with a small industry rather than volume.
Same bet: an abstract research-domain noun anchored on universities, labs and institutes putting their identity on the field, though broader and less commercially charged than one named technology.
What a .quantum domain is
.quantum is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, filed under AI & tech. 2 applicants have said publicly that they applied for .quantum.
Is the .quantum domain extension real yet?
.quantum 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 .quantum domain?
You can’t yet. ICANN publishes every applied-for string on Reveal Day, 7 October 2026 at 18:00 UTC. A .quantum name can only be registered after that, once the string is delegated and its registry opens. Last round's closest parallel to .quantum was .cloud, delegated on .
Is .quantum a real TLD?
Not yet. .quantum is not in the DNS root, so nothing resolves under it. It’s here because an applicant said publicly that it applied for .quantum in the ICANN 2026 new gTLD round. Every claim on this page links to its source.

- Band: 30-49, usable but limited. The word carries genuine cachet in tech branding and the quantum sector is widely treated as a growth area, so some real registrations and a handful of primary-identity uses over the next 5 years are plausible. It is not in the 50-69 band because the pool of quantum-focused companies is small relative to sectors that made suffix TLDs work, and by analogy the field's established players and funded startups have tended to build identity on .com or short incumbent endings, so sustained primary-identity demand is unproven and would need explaining. It is not in the 10-29 band because demand is tied to a durable industry theme rather than a joke or one-off event, and the string reads as a credible descriptor rather than pure vanity. By analogy with descriptive tech-word TLDs, the likely pattern is price-driven volume plus defensive and marketing registrations, with a thin aftermarket concentrated in a few dictionary-word second levels. The word's broad metaphorical use in marketing (quantum leap framing) widens the buyer pool slightly but dilutes the brand signal. Applicant context, stated neutrally from the verified facts: the applicant filed more than 300 strings in the round and lists this one under 'AI & Tech'; a large-portfolio applicant may market any single string less intensively than a single-TLD registry would, which tempers adoption expectations without changing the string's intrinsic merit. Main market uncertainty: whether quantum computing commercialization produces a startup wave dense enough within 5 years to make a sector-suffix identity fashionable the way it became for AI companies (analogy, not asserted with figures).
