.fusion
Is .fusion a real TLD? Who’s applying to run it?
Nobody has applied for .fusion in its own right, as of 7 October 2026. Radix named .fusion as the backup string of its .research application.
A real word with a hot energy-sector meaning, but too narrow to be a default identity; expect modest, price-driven registrations.
fusion-energy startups and research groups, fusion-cuisine restaurants, and brands using "fusion" as a merge-or-blend metaphor who want a short descriptive suffix instead of a .com
Nobody has applied for .fusion in its own right.
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 single named generation technology offered as a namespace, wagering that the firms building that one technology will put their primary identity on the technology rather than on the broader sector or their own brand.
Same buyer universe and the same open-generic sector play, but one rung broader — a whole industry's category noun rather than one contested technology inside it, so it does not need a single technology to win to be worth holding.
Covers the target's other life as an abstract, science-flavoured English noun with several unrelated meanings, where the bet is cross-sector brandability for registrants with no claim on the word rather than adoption by one industry.
What a .fusion domain is
.fusion is not a TLD yet. It is a string on our record of the ICANN 2026 new gTLD round, in our AI & tech category. Nobody has applied for .fusion in its own right. It is named on ICANN’s list as part of an application for another string.
Is the .fusion domain extension real yet?
.fusion 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 .fusion domain?
You can’t yet. A .fusion name can only be registered once the string is delegated (added to the DNS root) and its registry opens. Last round's closest parallel to .fusion was .solar, delegated on 28 December 2013.
Is .fusion a real TLD?
Not yet. .fusion is not in the DNS root, so nothing resolves under it. It’s here because ICANN’s list names .fusion as part of an application for another string. Every entry on this page links to its source.

- Band chosen: usable but limited (30-49). .fusion is a plain dictionary word with three live meanings: fusion energy (a sector attracting serious private and public interest), fusion cuisine, and the generic sense of blending things together. That gives it a broader buyer pool than a pure vanity string, and the energy-sector meaning gives it a credible primary-identity use for a small set of labs and startups, which is why it is not in the vanity band below. It is not in the strong-niche band above because none of those three meanings is a category where projects would default to the TLD without explanation: fusion-energy companies have .energy, .tech and .com as established alternatives (by analogy, single-sector word TLDs such as .solar and .energy saw real but small registration bases and thin aftermarkets, and .fusion is narrower than .energy), fusion restaurants are a long tail that mostly lives on .com or marketplace profiles, and the metaphorical sense produces one-off brand registrations rather than sustained demand. On the record the string is a replacement application by Radix whose primary string is .research, with no contention count and no category tag; that only informs adoption likelihood neutrally and does not change the market judgment. Main uncertainty: whether the fusion-energy sector grows fast enough within 5 years that a visible cluster of companies adopts .fusion as a primary identity, which would pull the string toward the top of its band or into the niche band; otherwise demand stays with generic-word hobby and restaurant registrations. Unknown: expected registration volume, wholesale pricing, and whether the operator will position it toward the energy sector.
