Independent Broker-Dealers: What the Public Data Shows

"Independent broker-dealer" is one of the most-used labels in U.S. wealth management and one of the few that no regulator recognizes. There is no independent category in the securities laws, none in FINRA's membership data, and no official list of independent firms. What exists instead is a business model — and a body of public data that tells you a great deal about it, if you know which numbers are real.

This page sets out what the term means, what the regulatory record actually shows about the firms it describes, and — just as important — which public filings will and will not support the figures these firms are usually ranked by.

What the term does and does not mean

Federal law defines the entity, not the adjective. The SEC's Guide to Broker-Dealer Registration defines a broker as "any person engaged in the business of effecting transactions in securities for the account of others" under Section 3(a)(4)(A) of the Exchange Act, and a dealer as "any person engaged in the business of buying and selling securities for his own account, through a broker or otherwise" under Section 3(a)(5)(A). Neither definition mentions independence, ownership or affiliation model.

"Independent" describes how the firm's advisors are affiliated with it. In the independent model, advisors typically operate their own practices, carry their own overhead and business risk, and affiliate with the broker-dealer for supervision, clearing, custody and product access. In the employee model — the wirehouses and bank-owned brokerages — advisors are salaried or draw-based staff of the firm, using its premises and brand.

That distinction has less regulatory weight than most people assume. The SEC guide is explicit on the point:

"We do not differentiate between employees and other associated persons for securities law purposes. Broker-dealers must supervise the securities activities of their personnel regardless of whether they are considered 'employees' or 'independent contractors' as defined under state law."

So independence changes the economics of an advisor's practice — payout, ownership, cost structure — but it does not reduce the supervisory obligations the firm owes over that advisor's securities business. Anyone evaluating an independent broker-dealer as a partner, an acquisition target or a technology customer should read that sentence twice. The supervision burden travels with the firm, not with the employment classification.

The market the term sits inside

Because "independent" is not a regulatory category, there is no official count of independent broker-dealers. There is, however, a precise count of broker-dealers overall, and its trend is the single most useful fact about this market.

FINRA's 2026 Industry Snapshot, published in May 2026 and reporting year-end figures, puts the number of FINRA-registered broker-dealer firms at 3,184 at the end of 2025. FINRA's five-year series in that report reads 3,394 (2021), 3,378 (2022), 3,298 (2023), 3,249 (2024) and 3,184 (2025) — a net decline of 210 firms, or about 6%, in four years.

Over the same period the number of people went the other way. FINRA counts 639,723 registered representatives at the end of 2025, up from 612,392 in 2021. Fewer firms, more advisors: that is consolidation stated as plainly as data can state it.

The size distribution is where the independent model becomes visible without being named. FINRA classifies member firms by headcount — large means 500 or more registered representatives, mid-size means 151 to 499, and small means 1 to 150. At the end of 2025 the split was 155 large firms, 197 mid-size firms and 2,832 small firms. Nearly nine in ten FINRA member firms have fewer than 151 registered people.

The dual-registration fact that reframes the category

FINRA's data on individuals is more revealing than its data on firms. Of the 639,723 people registered with a broker-dealer at the end of 2025, 331,802 — more than half — were also registered as investment adviser representatives. Another 94,562 individuals held investment adviser registration only, giving 734,285 securities-registered individuals in total.

The firm-level picture points the same way. FINRA reports 2,811 firms registered as broker-dealers only and 373 registered as both broker-dealer and investment adviser at the end of 2025, against 32,263 firms registered as investment advisers only — roughly ten investment adviser firms for every broker-dealer.

This matters for anyone building or buying technology for this market. The majority of the people an independent broker-dealer supervises are operating under two regulatory regimes at once, with different standards of conduct, different disclosure obligations and different supervisory records. A platform that models the advisor as purely brokerage-side is modeling a minority of the population.

The largest firm, and what can actually be verified about it

LPL Financial Holdings describes itself in its Form 10-K for the year ended December 31, 2025 as serving "the financial advisor-mediated marketplace as the nation's largest independent broker-dealer, a leading investment advisory firm, and a top custodian." That is the company's own characterization in an SEC filing rather than an independent ranking, and it is worth reading as such — but the scale behind it is reported and auditable.

In its second-quarter 2026 earnings release, dated July 30, 2026 and available through the company's SEC filings, LPL reported:

Metric	Q2 2026	Q2 2025
Advisors	32,475	29,353
Total client assets	$2,562.7 billion	$1,919.2 billion
Brokerage assets	$1,014.3 billion	$858.5 billion

Advisory assets rose 46% year over year to $1.5 trillion in the same release, and total organic net new assets were $23 billion in the quarter.

Part of that growth is acquired rather than organic. LPL's 2025 Form 10-K records that its acquisition of Commonwealth Financial Network — itself an independent broker-dealer — closed on August 1, 2025. Deals of that kind are the mechanism behind the firm-count decline FINRA measures, though an acquired broker-dealer may remain a separate FINRA member for some time after a transaction closes.

More is public than most people realize — and it is not what the rankings use

A common assumption is that privately held broker-dealers disclose nothing. That is wrong, and the correction is useful.

Every SEC-registered broker-dealer files an annual report on Form X-17A-5 Part III, and the SEC's filing instructions require part of it to be public regardless of ownership: "The public document must contain, at a minimum, the statement of financial condition, the notes to the statement of financial condition, and an accountant's report which covers the statement of financial condition." A filer may request confidential treatment for other components, but at least one document must be filed without that request, and the SEC states that anything not marked confidential "will be made public on EDGAR immediately after the individual files the reports on EDGAR."

So an audited balance sheet exists in public for private independent broker-dealers as well as listed ones. That is a far better starting point for diligence than a survey table.

What those filings do not reliably give you is the number the rankings use:

• A statement of financial condition is a balance sheet, not an income statement. Revenue is not among the items the SEC requires to be public, so a revenue league table cannot generally be assembled from these filings.
• The filer is the registered entity, not the group. The broker-dealer that files is often one subsidiary of a larger organization. Advisor headcounts and asset totals quoted for a "firm" frequently describe the parent, which is not what filed.
• Gross revenue is not comparable across payout models. Revenue at an independent broker-dealer includes the advisor payouts that pass straight through it. Two firms with identical retained economics can differ severalfold on headline revenue.
• The boundary is drawn by each publisher. Because no regulator maintains an independent category, every list decides for itself which firms qualify, and firms running both employee and independent channels may appear on one and not another.

This page therefore does not publish a ranked table of independent broker-dealers by revenue. Rankings from trade publications are often the only comparative view available and they have real value, but a figure taken from one belongs in a sentence that names the publisher and the year — not repeated as a fact about the industry.

How to read this market

For an operator, an acquirer or a vendor evaluating the independent channel, the public record supports a small number of firm conclusions:

Consolidation is measurable, not anecdotal. FINRA's own series shows 210 fewer member firms in 2025 than in 2021 while registered representatives grew by more than 27,000. Scale is accumulating in fewer places.

Most firms are small. With 2,832 of 3,184 member firms holding 150 or fewer registered representatives, the modal broker-dealer is a small business. Technology, compliance and clearing economics that assume enterprise scale do not describe most of the market.

The advisor is usually dual-hatted. With more than half of registered representatives also registered as investment adviser representatives, brokerage-only assumptions about workflow, supervision and disclosure are the exception rather than the rule.

The visible top of the market is genuinely large. One firm reported more than 32,000 advisors and over $2.5 trillion in client assets in mid-2026. Whatever the ranking methodology, the distance between the top of this market and its median member is very wide.
