Still a .com market: 2,851 of 3,461 vendor domains end in .com, and only 65 end in .ai
Sorted by top-level domain, the index shows an industry that talks about reinvention and registers the same suffix it did twenty years ago. .com holds 82.4% of vendor domains, and the entire .io, .ai, and .co cohort adds up to 322.
Every listing in The Wall's index carries a website, and the August 9 snapshot records 3,461 domain strings across 70 distinct top-level domains. Sorted by suffix, the distribution barely moves off a single answer. 2,851 domains end in .com. That is 82.4% of the index, and it leaves 610 domains, 17.6%, to split every other suffix in existence between them.
The alternative-suffix cohort that gets the most attention is smaller than its share of voice. .co, .io, and .ai together account for 322 domains, 9.3% of the index. Startup-flavored suffixes have not displaced .com in this market. They have taken roughly one domain in eleven.
Top-level domains across 3,461 vendor websites
| Top-level domain | Domains | Share of index |
|---|---|---|
| .com | 2,851 | 82.4% |
| .co | 139 | 4.0% |
| .io | 118 | 3.4% |
| .ai | 65 | 1.9% |
| .agency | 58 | 1.7% |
| .net | 37 | 1.1% |
| .studio | 25 | 0.7% |
| .us | 13 | 0.4% |
| .org | 12 | 0.3% |
| .media | 12 | 0.3% |
| All other suffixes (60 TLDs) | 131 | 3.8% |
The tail is long and almost entirely decorative. 40 of the 70 suffixes in the index appear exactly once. The suffixes that describe what a firm does, .agency, .studio, .media, .digital, .marketing, and .design, account for 124 domains combined, 3.6% of the index. Hyphenated domains are rarer still at 97, 2.8%, and the median second-level domain runs 10 characters.
One number is worth holding onto. The index's AI Marketing pillar carries 105 listings in the same snapshot, and only 65 domains in the entire 3,461-domain index end in .ai. The suffix cannot cover the category even if every .ai registrant in the index were an AI-marketing firm. A buyer reading domain suffixes as a capability signal is reading noise. The category field on a profile is the signal.
Two sourcing notes. Suffix counts are computed from the domain strings recorded in the August 9 index snapshot, which holds 3,461 domain records against a 3,460-listing total, a one-record variance carried through from the capture. A small number of single-occurrence suffixes appear to be malformed capture artifacts rather than real registrations; they sit inside the 131-domain "all other" row and change none of the figures above by more than a rounding step. How domains are checked before a listing publishes is covered in the verification briefing.
How this was computed. Figures are computed from The Wall's index of approved, US-based, machine-verified-live listings, using the index snapshot current when each briefing was published: 2,286 listings at launch (August 3, 2026) and 3,460 in the latest snapshot (captured August 9, 2026). Engagement data (rates, minimum project sizes, team sizes, founding years, ratings) are provider-declared figures published on public Clutch profiles; they were present for 1,738 of the 2,286 launch listings, and coverage counts for later snapshots are stated inside each briefing that uses them. Percentages of "disclosed" values exclude listings that publish no figure. Nothing in this briefing is estimated or modeled. Sourcing standards: editorial policy.
