2026 data ranking
A low leader share means AI assistants spread their recommendations across many businesses instead of repeatedly naming one favorite. We ranked the five most open categories in MentionedOn’s live corpus of 42,100 recorded answers across 840 city-and-category leaderboards.
Across 40 cities, the most-mentioned business captured only about 20% of category mentions on average. The remaining mentions were split among competitors, which makes this one of the least concentrated categories in the dataset.

Leader share measures how much of each market’s observed AI mentions went to its top business. Lower concentration suggests more room to enter the answer set, but it does not guarantee placement. Results vary by city, model, prompt, and refresh date. Business names are normalized from model output, not matched to an audited business registry.
