Most Popular Domain Extensions in 2026: Deep Analysis

January 1, 2026

Across every TLD we track, we're seeing something unprecedented: every single extension is growing. No exceptions. This contrasts sharply with previous years where there were always winners and losers.

As of late 2025, total global domain registrations reached 386.9 million, up 6.2% year-over-year and accelerating.

.com — 303.7 Million Registrations, +18% Growth

.com currently has 303.7 million registered domains, achieving a strong 18% year-over-year rebound. The aftermarket is equally strong — average resale price surged 63.6% to $23,264.

The largest domain transaction in history: ai.com sold for $70 million in April 2025.

.ai — 1 Million Registrations, $239K Average Resale

.ai crossed 1 million registrations on January 2, 2026. Its average resale price of $239,516 is roughly 10x that of .com premium domains.

If you're building an AI startup, a .ai domain is now virtually a requirement.

.xyz — 10 Million Registrations, +240% Growth

The fastest-growing TLD in 2026 by a wide margin. Despite explosive registration growth, its aftermarket price declined 43.6% — suggesting a shift from speculation to actual usage.

Looking Ahead

ICANN will open applications for entirely new TLDs from April 30 to August 12, 2026 — the first new round since 2012.
