What adviser size tells you—and what it leaves out

The middle of the list deserves a look

Large firms are easy to notice. In our covered September 2026 population, however, 9,577 of 14,412 advisers with valid reported regulatory AUM were below $1 billion. That is 66.5%. The median was $485,745,940.00.

Those figures describe this study’s covered legal entities, not the entire adviser industry. The population contains different business models, including institutional managers and firms serving individuals. It is not a ready-made shopping list for personal financial advice.

A league table can tell you who is bigger. It cannot tell you who should get the job.

What the median actually answers

The median is the middle of the ordered valid amounts. It describes a central firm by reported asset size without letting the largest values dominate the result. It is not the average amount invested by a client, a recommended account balance or an estimate of a firm’s value.

Regulatory AUM measures reported assets under the filing’s definition. It does not measure investment performance, service quality or how much attention a particular client receives. A larger number may help describe the scale of a business; deciding whether that business fits your needs requires different evidence.

Keep the legal entity, source month and asset definition together. A group-level headline, an adviser’s regulatory AUM and the securities reported on Form 13F can describe different things. Read the asset-definition guide before comparing them.

Turn a size comparison into a useful shortlist

1. Define the work. Start with the services you need. Reported client types and services are more useful here than a position in an AUM ranking.
2. Check the entity. Open the firm profile and confirm its legal identity and CRD. Similar names and affiliated entities should not silently become one business.
3. Align the dates. Compare a common source month where possible. A snapshot month identifies the archived data, not necessarily the date the assets were measured.
4. Read the disclosures. Check fees, account minimums and service terms in the firm’s own materials. The directory does not establish suitability or recommend an adviser.

A city page helps narrow geography. Its membership follows qualified reported principal offices, not every branch or every firm serving local clients. Start with Boulder, Buffalo, Carlsbad, California, Plymouth, Minnesota or Rochester, New York, or browse the full directory.

Source, calculation and limits

This article uses the unchanged September 2026 adviser-size study and methodology. Of 17,301 eligible directory firms, 152 had an older source month and 2,286 had unavailable or unqualified public principal-office geography. The resulting covered population is 14,863 firms.

The percentage divides the two size bands below $1 billion by the 14,412 valid amounts, then rounds to one decimal place. The 451 missing amounts are excluded from that denominator; they are not zero. Affiliated legal entities are not consolidated. We do not add these assets together as unique investor wealth, because assets can overlap between managers.

No new source data was acquired for this article. The underlying study provides state tables, exact band definitions and SEC Form ADV source information. Size alone does not establish returns, organic growth, advice quality or client outcomes.
