Concentration index by category

How this is computed

For each category we count the brands whose ultimate controlling owner is each company, turn the counts into shares of the category, then square each share (as a percentage) and add them up. That sum is the Herfindahl-Hirschman Index, or HHI. It runs from near 0 (many owners with a few brands each) to 10,000 (one owner holds everything). It counts brands, not revenue, because Brandtree does not hold revenue by brand, so a company with one huge brand and a company with one tiny brand count the same. The top-three share is the percentage of brands held by the three largest owners.

Only categories with at least 8 brands under a verified or reported controlling owner and at least 2 owners are listed, the same bar the category pages use. Licensed brands and minority stakes are not counted as ownership. Categories nest, so a parent such as Beer includes the brands of its sub-categories and appears alongside them.

Reading the number. Competition regulators have long treated an HHI under 1,500 as unconcentrated, 1,500 to 2,500 as moderately concentrated and above 2,500 as highly concentrated. Those bands are written for revenue shares in a defined market; applied to brand counts in a catalogue category they are only a rough guide. An HHI of 2,500 is what four equal owners would score; 5,000 is two equal owners.

Coverage caveat. Brandtree adds a company when its filings list its brands, so large owners are better covered than small independents. Small categories can score as concentrated simply because few brands are tracked, so check the brand count beside each score. Scores describe this dataset as of 2026-10-16, not the whole market.
