Of the 46,986 domains that came up for renewal between Aug 2025 and Jul 2026, the share renewed rather than deleted. How this is computed.
For comparison, the median new gTLD keeps 67.40% and .com, .net and .org together keep 73.18%.

74,103 attributed to registrars in Jul 2026, against 73,230 in 10 Nov 2026’s zone — the zone is 873 smaller. The two are months apart, and a registry's own count also includes registrations that are not delegated in the zone. Why there are two clocks.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for July 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
