Nearly every stock purchase in the United States runs through a broker-dealer, yet the term covers firms as different as a national wirehouse, a mobile trading app, and a back-office clearing operation. According to FINRA’s 2026 Industry Snapshot, 3,184 FINRA-registered broker-dealers were operating at the end of 2025.
What Is a Broker-Dealer?
A broker-dealer is a firm or individual that trades securities in two capacities: as a broker, executing transactions on behalf of clients, and as a dealer, buying and selling securities for its own account as principal.
Every broker-dealer conducting business with the public in the United States must register with the Securities and Exchange Commission and become a FINRA member.
Registration begins with Form BD, the Uniform Application for Broker-Dealer Registration, which is filed with the SEC, self-regulatory organizations including FINRA, and jurisdictions, submitted electronically before a signed and notarized copy is sent to FINRA.
The type of firm behind an account matters, because business model shapes compensation structure and the resources available when a dispute arises, a point addressed at the close of this guide.

Broker-Dealer vs. Investment Advisor
The most consequential distinction is the legal standard each owes its clients. Investment advisors are held to a fiduciary standard, while broker-dealers historically operated under a suitability standard supplemented, since June 30, 2020, by Regulation Best Interest.
The SEC’s interpretation of adviser fiduciary duty states that under the duty of loyalty an investment adviser must eliminate or make full and fair disclosure of all conflicts of interest so that a client can provide informed consent, whereas a broker under the suitability standard needed only to reasonably believe a recommendation was appropriate.
That difference carries practical weight where conflicts of interest exist. A fiduciary advisor’s obligation applies on a continuous, ongoing basis, while a broker’s best-interest duty attaches at the moment a recommendation is made.
Because broker-dealers may earn commissions and distribute proprietary products, the compensation model itself can create incentives that a fiduciary structure is designed to address.
More than half of FINRA-registered representatives now hold both credentials: according to FINRA’s 2026 Industry Snapshot, 331,802 individuals maintain both broker-dealer and investment adviser registration, which blurs the line for many investors trying to identify which standard applies to their account.
Firms and advisers operating under the advisory standard, including dually registered professionals, are addressed further in the firm’s discussion of registered investment adviser representation.
Who is considered a broker-dealer?
A broker-dealer is a firm or individual engaged in the business of buying and selling securities, acting as a broker when executing trades for clients and as a dealer when trading for its own account. To conduct securities transactions with the public in the United States, a broker-dealer must register with the SEC and become a FINRA member by filing Form BD.
Types of Broker-Dealers, With Real Examples
Broker-dealers are most usefully categorized by business model and structure rather than by size alone. The sections below group real firms into the categories investors and registered representatives encounter most often, from national wirehouses to the clearing firms that operate behind the scenes.
Wirehouses
Wirehouses are large, full-service national firms, typically affiliated with a bank or a major brokerage franchise, that maintain in-house research, proprietary product lines, and extensive advisor networks. Commonly cited wirehouse firms include:
Merrill Lynch
Morgan Stanley
UBS
Wells Fargo Advisors
Independent Broker-Dealers
Under the independent model, financial professionals operate under their own business name or brand while remaining licensed through the broker-dealer, which handles compliance oversight and trade execution. This structure gives advisors greater autonomy over their practice while leaving regulatory obligations with the firm. Representative independent broker-dealers include:
LPL Financial
Raymond James
Commonwealth Financial Network
Ameriprise
Regional Broker-Dealers
Regional broker-dealers maintain a strong footprint in specific geographic areas and are often full-service in character but smaller than the national wirehouses. Well-known regional firms include:
Stifel
Edward Jones
D.A. Davidson
Full-Service vs. Discount Brokerages
Full-service brokerages pair advice with execution and generally charge higher fees for that combination. Discount and online brokerages are built for self-directed investors who buy and sell securities on their own, often at low or zero commission.
Charles Schwab, Fidelity, and E-Trade are frequently cited crossover examples, having evolved from discount brokerages into firms that now offer both self-directed platforms and advisory services.
The distinction has blurred further as full-service firms add digital self-serve tools, leaving business model, not fee schedule alone, as the more reliable way to classify a firm.
Clearing Firms
Not every broker-dealer holds the assets its clients see on a statement. The industry distinguishes between introducing broker-dealers, which interact with clients and originate transactions, and clearing firms, which hold custody of securities, settle trades, and provide the back-office infrastructure that smaller introducing firms rely on. Major clearing firms include:
Pershing (a BNY company)
National Financial Services (Fidelity’s clearing arm)
Apex Clearing
This matters for investors because the firm that actually holds custody of the assets is often not the firm the client interacts with day to day. When something goes wrong, identifying both the introducing and the clearing broker-dealer can be central to understanding where responsibility lies.
Insurance- and Bank-Affiliated Broker-Dealers
Some broker-dealers are owned by or affiliated with insurance companies or banks and frequently distribute proprietary annuity or insurance products alongside conventional securities.
Equitable Advisors, a member of FINRA affiliated with the Equitable insurance group and a subsidiary of Equitable Holdings, Inc., is one example of an insurer-owned broker-dealer.
These affiliations are relevant when evaluating product recommendations, because a firm that manufactures the products it sells may have conflicts of interest that Regulation Best Interest requires it to disclose.
The Broker-Dealer Landscape Is Evolving
The composition of the industry is shifting. Fintech platforms and robo-advisors such as Betterment and Wealthfront have introduced automated, low-cost portfolio management, and Robinhood established itself as a mobile-first broker-dealer built around commission-free trading. These entrants have pressured traditional firms to lower costs and expand digital access.
At the same time, the industry is consolidating. FINRA reports that the number of member firms declined due to ongoing concentration even as the count of registered representatives reached record levels. The result is a smaller number of firms that vary widely in size, capital, and compliance infrastructure.
How Many Broker-Dealers Are There?
FINRA publishes annual firm counts in its Industry Snapshot, and the multi-year trend is downward. According to FINRA’s 2026 Industry Snapshot firm data, the total number of FINRA-registered broker-dealers fell to 3,184 at the end of 2025, compared with 3,249 a year earlier and down from 3,394 in 2021. During 2025 alone, 163 firms left FINRA membership, compared with just 98 new entrants.
Small firms have absorbed most of the contraction. The number of firms with between one and 150 registered representatives fell to 2,832, down from 3,048 in 2021. Meanwhile, the workforce grew: registered representatives reached 639,723 in 2025, a 5% increase since 2021, according to FINRA’s announcement of the report.
A declining firm count paired with a rising headcount means more representatives concentrated in fewer, larger firms. It also means the size and resources of the firm behind any given account vary considerably, which affects both investors and registered representatives when a dispute arises.

How to Verify a Broker-Dealer
Anyone can confirm a firm’s registration and disciplinary history in a few minutes using free public tools. The walkthrough below identifies where to look and what each source discloses.
FINRA’s firm registry. FINRA maintains a public list of the firms it regulates, which confirms whether an entity is a current member in good standing. This is the baseline check: a firm that does business with the public but does not appear in FINRA’s records is a warning sign.
BrokerCheck. BrokerCheck shows a snapshot of a broker’s employment history, regulatory actions, investment-related licensing information, arbitrations, and complaints. To use it, enter the name of the firm or individual at brokercheck.finra.org. According to FINRA’s guide to BrokerCheck, the report includes the individual’s employment history for the last 10 years and a qualifications section listing current registrations or licenses, along with any disclosure events. The underlying data comes from the Central Registration Depository, so the same filings regulators review are visible to the public.
Form BD. Because Form BD is the Uniform Application for Broker-Dealer Registration filed with the SEC, self-regulatory organizations including FINRA, and jurisdictions, it is the source document behind a firm’s public profile. Form BD is a disclosure record that details a firm’s ownership, business lines, control persons, and disciplinary history, providing the structural facts that reveal how a firm is organized and who stands behind it.
The firm’s own disclosures. A firm’s website is a legitimate part of due diligence when read critically. Review its compliance and legal disclosure pages and its client relationship summary (Form CRS), which is required to summarize services, fees, conflicts of interest, and the standard of conduct the firm owes clients. These documents state, in the firm’s own words, how it is compensated and where its interests may diverge from a client’s.
Why a Clean BrokerCheck Record Matters
For investors, a clean record is a baseline diligence signal before opening an account or entrusting an advisor with assets. Disclosures do not automatically indicate wrongdoing, but a pattern of customer complaints or regulatory actions warrants closer scrutiny.
For registered representatives, the stakes are different but equally real: disclosures follow a professional across firms and can affect employability, because prospective employers review the same record. That reality makes accurate U4 and U5 reporting consequential and, where warranted, makes the expungement of inaccurate disclosures important as well.
What are the major broker-dealers in the US?
There is no single official ranking of broker-dealers, and any list depends on the metric chosen: assets, revenue, or advisor headcount. Firms consistently described as major by size and prominence include Merrill Lynch, Morgan Stanley, Wells Fargo Advisors, UBS, LPL Financial, Raymond James, Edward Jones, Charles Schwab, Fidelity, and Ameriprise. This is an illustrative list of large firms, not a ranked measurement.
Why Firm Type Matters When Something Goes Wrong
The category a broker-dealer falls into is not incidental. It has direct consequences for accountability and for the support available when a dispute arises.
For investors. A broker-dealer has a supervisory duty over its registered representatives, and claims for broker misconduct involving a securities transaction are frequently brought against the firm itself, not only the individual who committed the alleged wrong.
Firm type can affect this: a large wirehouse and a small independent broker-dealer may have very different insurance coverage and financial resources with which to respond to a claim.
Investor-side claims are typically resolved through FINRA arbitration, and Bakhtiari & Harrison handles investor cases on a contingency fee basis: no recovery, no fee.
For registered representatives. When a rep is hired or leaves a firm, the firm files disclosures on that rep’s record through Form U4 and Form U5, and the language a firm chooses on a U5 termination can shape a career.
Firm size and resources affect the support a representative receives during a dispute or an expungement effort: larger firms may provide counsel and administrative assistance, while a representative at a smaller firm, or one who has left the firm entirely, may find no institutional support at all.
Representatives facing that gap can review how FINRA expungement works when a firm declines to participate, and can learn more about representation for financial professionals.
The type of broker-dealer behind an account or a registration determines who bears responsibility and who has the resources to respond when a matter proceeds to arbitration or a regulatory investigation.
Speak With a Securities Attorney About a Broker-Dealer Dispute
Identifying the type of broker-dealer involved is the first step. Resolving a dispute with one requires counsel who understands how these firms operate from the inside. Bakhtiari & Harrison represents investors with claims against broker-dealers, as well as financial professionals in disputes with their firms, in FINRA arbitration and in court.
For investors: When losses trace back to a broker’s recommendations or a firm’s failure to supervise, we evaluate whether a claim against the broker-dealer is viable. All investor cases are handled on a contingency fee basis: no recovery, no fee.
For registered representatives: When a Form U5 termination disclosure, a customer complaint, or a dispute with a firm is affecting a career, we advise on U5 defamation, FINRA expungement, and employment disputes with broker-dealers.
