.one TLD stats

• Run by One.com A/S
• Sold most by NameSilo, LLC, 14.8% in March 2025
• Our model compares it with 21 strings in the 2026 round

Names on the books at the end of each year since general availability, from the registry's monthly reports to ICANN, through May 2026. The marked point is the zone count of 13 Oct 2026, a different count taken on one night.

In its first year, to April 2016, 40 registrars held 10 or more .one names and the largest held 29%; by its eleventh, to April 2026, 71 did and the largest held 20%.

Year 1 starts at general availability and each year is labelled by the month it ends. Registrars with 10 or more names and the largest registrar's share are read at that month. A year with fewer than nine monthly reports is left blank.

NameSilo, LLC held 14.8% of .one names in March 2025; the largest five together held 64.2%.

Shares add to 100%. From the registry's report for March 2025.

When we scored the 2026 round, our model listed .one among the closest 2012-round TLDs for 21 applied-for strings. No applicant made these comparisons; strong and moderate are how close it judged each match.

Cross-checkThe registry reported 273,137 names for Mar 2025; the zone on Oct 13, 2026 held 9,944 fewer. The two are counted differently and 19 months apart: a registered name that is not delegated never appears in the zone, and a zone file is read on one night, a report at a month's end.

Counted from the registry’s own zone file on the night of Oct 13, 2026. A zone count is not domains under management: a registered name that is not delegated never appears in the zone, and a name on hold leaves the zone while it stays registered. The two numbers will not agree, and neither is wrong.
