The largest market in the corpus writes AI into roles more often than any other, and most of those roles name nobody to overrule it.
Scale, and a sector mix that no other market shares.
Across 15,194 live United States specifications from 128 employers, as at 14 September 2026.
Where a cell falls under 50 specifications the share is held and counts print beside shares. AI-central share moves with sector mix; the sector cell is named beside every share.
How many United States specifications mention AI
3,748 of 15,194, 24.7%. Technology is the largest United States cell at 5,627 live specifications, more than Australia's entire live count; financial services 4,120; advertising and agencies 2,064. The United States share is a technology share before it is a national one. The comparison page states this beside every United States figure.
Which United States sectors write AI into roles

How many United States AI roles define who overrules the model
