Published . This page is the permanent record of the September 2026 Edition: the standing of every category as measured in it, under vendor table v2026-11-09.1. The unqualified category addresses and the home page carry the latest edition.
No category changed leader.
The floor is 12 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one can't be told apart from repeat variation, and both are shown. Each index measures its own floor from its own repeat, over its own categories, so the floor differs from one index to the next. How the floor is measured · Every change resolves to its category page.
