.icu TLD stats

• Run by ShortDot
• Our model compares it with 12 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 24 Oct 2026, a different count taken on one night.

In its first year, to April 2019, 39 registrars held 10 or more .icu names and the largest held 32%; by its eighth, to April 2026, 107 did and the largest held 18%.

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.

GNAME.COM PTE. LTD. held 17.9% of .icu names in May 2026; the largest five together held 50.9%.

Shares add to 100%. From the registry's report for May 2026.

When we scored the 2026 round, our model listed .icu among the closest 2012-round TLDs for 12 applied-for strings. No applicant made these comparisons; strong and moderate are how close it judged each match.

Counted from the registry’s own zone file on the night of Oct 24, 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.

Names under management at month end, as the registry reported it. Dashed months are third-party estimates. Sunrise Apr 2018 to May 2018; general registration May 2018.
