What Is an Independent RIA? The Definition, the Rules, and How It Differs From Corporate and Hybrid RIAs

The short answer: An independent RIA is a registered investment adviser owned by its own advisors rather than by a broker-dealer, bank or wirehouse. It is registered with the SEC or its home state, owes clients a fiduciary duty, is typically paid through fees rather than commissions, and holds client assets at an outside custodian.

"Registered investment adviser" is the regulatory status. "Independent" describes ownership. Plenty of RIAs are owned by broker-dealers and large financial firms; an independent one belongs to the people who advise its clients, and they control its agreements, its technology, its investment offering and its enterprise value.

The three kinds of RIA an advisor meets

Advisors leaving a wirehouse or a broker-dealer hear three terms that sound alike and describe different ownership:

Michael Kitces described the corporate side plainly: in a corporate RIA the advisor uses the firm's processes, systems and software, while in an independent RIA the advisor controls the agreements, the offering, the systems and the technology. The hybrid sits between the two, owning the advisory business while keeping a broker-dealer for commission products; what a hybrid RIA is covers it in full.

Who regulates an independent RIA

Size decides. Under Section 203A of the Investment Advisers Act and SEC Rule 203A-1:

• Under $100 million under management, an adviser generally registers with its home state. Advisers under $25 million generally cannot register with the SEC at all.
• Between $100 million and $110 million, the adviser may register with the SEC but need not.
• At $110 million, it must register with the SEC, and once registered it need not withdraw unless assets fall below $90 million.

Two points surprise advisors. First, the people are registered separately from the firm: investment adviser representatives are registered by the states, including those who work for SEC-registered firms, according to NASAA. Second, the standard is the same at any size. An investment adviser is a fiduciary under federal law, and the SEC's 2019 interpretation describes that duty as a duty of care and a duty of loyalty, owed across the whole relationship.

Most RIAs are small firms

The Investment Adviser Association's 2026 snapshot, built from the Forms ADV on file, counts 16,544 SEC-registered advisers. The median firm has 8 employees and $446.9 million under management, and 92.8% of them have 100 or fewer non-clerical employees. Beneath them sit 15,799 state-registered advisers, the average of which has one non-clerical employee.

That is the shape of the channel: a large number of small, owner-run firms, with the largest RIAs pulling the averages up. The SEC's own adviser data, sorted by state, is the basis of our RIAs by state directory.

How big the independent channel is, and how fast it grows

Cerulli, as reported by WealthManagement.com, put independent RIAs at about 16% of advisor headcount and 16% of assets on 2023 data, up from 12% of assets a decade earlier; hybrid RIAs added another 13% of advisors and 11% of assets. Cerulli's 2023 research had the number of independent RIA firms growing 2.4% a year over the preceding decade and the advisors working in them growing 5.2% a year.

The advisors already there tend to stay. Cerulli's February 2026 research found 88% of independent RIA advisors very likely to stay with their current firm over the next 12 months, and 97% of those who would switch saying they would move to another independent RIA.

Three ways to become one

Start your own. The most control and the most work: registration, a compliance program, a custodian, technology, insurance and staff. The dollar cost of launching is modest next to the months of operating lift, which what it costs to start an RIA or join a platform sets out line by line.

Join an existing independent RIA. You trade some ownership, often all of it at first, for a firm that already runs. The questions are the ones any partner asks: what you own, what you can build, and what happens on a sale.

Launch through a supported-independence platform. The platform runs the middle and back office for a share of revenue while you own the practice. Kitces's 2024 analysis of affiliation models puts the general rule simply: the more services a platform covers, the more it charges and the lower the advisor's effective payout. Independent RIA platforms compared lays out the five types.

What changes for the advisor

• Fees only. A fully independent RIA earns advisory fees and sells no commission products. Advisors who leave a broker-dealer let the Series 7 lapse, and the two-year rule decides how long the door stays open.
• Custody moves outside. Client assets sit at a qualified custodian in accounts titled to the client, never with the advisor. How custody actually works explains the mechanics clients will ask about.
• The business becomes an asset. An advisor who owns the RIA owns its enterprise value, which is the number that matters at succession.

How to decide

The decision comes down to three numbers for your own practice: what share of revenue is advisory versus commission, what the practice nets after the costs of running it, and what it would be worth as a business you own. Going independent as a financial advisor compares all four paths side by side.

Advisors who want those three numbers run on their own practice, confidentially, are welcome to request an introduction.
