Before most financial advisors pick out office furniture or decide on a logo, they have to answer one much bigger question: who’s going to hold the money?
That’s the RIA custodian question. And it’s one of the most important calls you’ll make as a registered investment advisor. In the financial services world, your custodian shapes your pricing, your daily workflow, your tech stack, and what your clients actually experience when they log in to see their accounts.
This guide walks through what an RIA custodian is, what they actually do, how they make money, who the major providers are in 2026, and how to pick the right one for your firm.
What is an RIA Custodian?
An RIA custodian is an independent, regulated financial institution that holds client assets on behalf of a registered investment advisor and executes the trades the advisor places. The custodian keeps the securities and cash, settles transactions, maintains records, and sends statements and tax forms to clients. The advisor manages the strategy. The custodian handles the money.
This split isn’t optional. The Investment Advisers Act of 1940 requires RIAs to use a separate “qualified custodian” to hold client funds and securities. The point is to keep advisors from ever touching client money directly. If you want a recent reminder of why that rule exists, look at the FTX case. Sam Bankman-Fried and his team commingled client funds with the firm’s own trading book. That’s exactly what the custody rule is designed to prevent.
Under SEC rules, a qualified custodian has to be one of the following:
- A federal or state-chartered bank or savings association
- A registered broker-dealer
- A trust company that meets certain requirements (many trust companies are set up specifically to serve as RIA custodians)
- A registered futures commission merchant
- A foreign financial institution that meets specific requirements
Banks, broker-dealers, and trust companies all fall under the same umbrella of qualified financial institutions, each with their own regulatory oversight.
The SEC has been working on updates to the custody rule (sometimes called the Safeguarding Rule) that could tighten things further. Worth keeping an eye on, but the core requirement isn’t changing.
Think of the custodian as a bank vault with a trading desk attached. You’re the architect drawing up the plan. They’re holding the blueprints and the safe.
What Does an RIA custodian Do Day-to-Day?
Day in, day out, your custodian handles the operational layer of your business. That includes:
- Holding client cash and securities in accounts titled in the client’s name
- Executing the trades you place: equities, bonds, mutual funds, ETFs, and other investment products
- Settling transactions and keeping the books of record
- Producing monthly statements, trade confirmations, and year-end tax forms like 1099s
- Running the brokerage infrastructure your clients see when they log in
- In many cases, providing a tech platform, research tools, and a support team for your staff
What they don’t do is give the advice, pick the investments, or own the client relationship. That’s your job. The custodian runs the plumbing. You run the business.
A good custodial services partner makes this invisible. A bad one shows up in your inbox every week in the form of mistakes your client service associate has to clean up.
How do RIA custodians make money?
Most RIA custodians don’t charge advisors a direct fee to hold assets. That sounds great until you look at how they actually generate revenue. The business model works through a handful of channels:
- Ticket charges and transaction fees. A few dollars per trade, usually passed through to the client.
- Cash sweep spreads. This is the big one. When your client’s uninvested cash sits in a sweep account, the custodian earns interest on it and passes only a portion back. The spread is how many custodians quietly make most of their money.
- Payment for order flow. When trades route to certain market makers, the custodian can get paid.
- Margin lending interest. On client accounts that borrow against their portfolios.
- Mutual fund and alternative investment fees. Including revenue sharing and markups on in-house products.
- Paid software tiers and premium services for advisor firms that want more.
Here’s the part to remember: “free custody” isn’t really free. Your clients are paying, just not in a line-item way. Custodians are required to provide disclosures about these revenue streams, and it’s worth actually reading them. The more transparent a custodian is about pricing, the less likely you are to have an awkward conversation with a client down the road.
How your Clients’ Money is Protected
This is the section most articles skip, and it’s one your clients will ask you about. Here’s the short version.
Securities held at a broker-dealer custodian are generally covered by SIPC (Securities Investor Protection Corporation) up to $500,000 per client, including a $250,000 limit for cash. SIPC doesn’t protect against market losses. It protects against the custodian itself going under and client assets going missing. Many major custodians also carry supplemental insurance on top of SIPC coverage.
Cash held at a bank custodian is typically FDIC insured up to $250,000 per depositor per bank. Many custodians use a “cash sweep” that spreads client cash across multiple partner banks, which multiplies the FDIC coverage.
On the regulatory side, FINRA oversees the broker-dealer custodians, the SEC oversees the advisors, and both get visibility into what’s happening. RIAs with custody of client assets also face annual surprise exams by an independent accountant. That’s an extra check to make sure the assets on the statements actually exist.
None of this makes a custodian bulletproof. But the layered protection is why RIAs can confidently tell clients their assets are safe even when the market gets ugly.
The Major RIA Custodians in 2026
The RIA custody market is concentrated. Schwab alone shows up as a custodian for more than 58% of the 23,000+ RIA firms tracked in AdvizorPro’s 2025 market analysis, with Fidelity a distant second.
But the market is shifting. Nearly 30% of RIAs now use two or more custodians, and tech-first newcomers like Altruist are growing fast. Here’s a look at the major players.
Charles Schwab Advisor Services
The default for most independent RIAs. Schwab holds more than $5 trillion in RIA assets as of late 2025, has no AUM minimums for most firms, and offers the deepest integration ecosystem in the space. Charles Schwab offers the iRebal rebalancing tool, a huge library of third-party tech integrations, and transition help for advisors going independent.
The trade-off: if you’re a small firm, you can feel small. The best service levels tend to go to the biggest relationships.
Fidelity Institutional
The solid number two. Fidelity’s institutional wealth services arm supports more than 3,300 advisory firms with its Wealthscape platform, which offers strong proprietary tools for account opening, trading, and reporting, plus open architecture for third-party integrations.
Fidelity typically looks for higher AUM levels than Schwab to bring on a new RIA, often in the $50M to $100M range, unless you’re joining a firm that already custodies there. That makes it tougher for a brand-new RIA to get in the door.
BNY Pershing
BNY Pershing has more than $3 trillion in assets under custody or administration across 1,000+ wealth management clients in 30 countries. Pershing is often called the third of the Big 3 custodians, and it’s a popular choice for larger, professionally-managed firms that want a partner without a retail division competing for their clients. Pershing also provides clearing services to independent broker-dealers and other custodians. It’s a favorite for family office operators and firms serving high-net-worth clients.
LPL Financial
LPL services and custodies roughly $2.3 trillion in brokerage and advisory assets across approximately 1,100 financial institutions and 8 million clients. On the pure RIA side, independent RIA advisory assets hit $324.8 billion at the end of Q3 2025. LPL is the underrated option. It’s better known as a broker-dealer, but it’s a legitimate custodial option, especially for hybrid and breakaway advisors who want a broader platform of services bundled in. LPL has been picking up new clients from firms affected by the Schwab/TD Ameritrade merger.
Altruist
The fast-growing tech-first newcomer. Founded in 2018, Altruist now serves over 4,900 advisors and was the fastest-growing RIA custodian according to the 2025 T3 Software Study.
Its pitch is simple: modern software, flat-fee pricing, no minimums, and deeply integrated technology. Fractional shares, native tax management, and a clean trading platform make it popular with new RIAs, breakaways, and smaller independent advisors.
Altruist acquired Shareholders Service Group (SSG) in 2023, picking up SSG’s 1,600+ advisors and its high-touch service model. If you’re starting a firm in 2026 and you don’t have $50M in AUM on day one, Altruist is probably on your shortlist.
Raymond James
Raymond James has 8,900+ financial advisors firm-wide across all affiliation models, with a dedicated RIA & Custody Services division. Raymond James is a well-known brokerage house that’s more recently leaned into the custodial space. Over the past five years, firms averaging more than $600 million in assets have joined their RIA platform. Raymond James caters to HNW clients and firms doing deeper wealth management and financial planning work.
Interactive Brokers
Interactive Brokers serves around 3,600 financial advisors on its platform. No ticket charges, no custodial fees, no minimums, no in-house products competing with yours. Strong fit for advisors who trade internationally, use options heavily, or serve sophisticated clients who want access to things other custodians don’t offer.
TradePMR
Founded in 1998 by a former RIA and acquired by Robinhood in February 2025 for approximately $300 million. TradePMR supports around 350 RIA firms with roughly $43 billion in assets on its Fusion platform. Robinhood plans to use TradePMR as the backbone for a new referral program connecting its 24 million retail accounts to advisory firms.
Axos Advisor Services
Formerly E*TRADE Advisor Services, bought back from Morgan Stanley and rebranded. Axos Clearing (which includes Axos Advisor Services) had approximately $37.1 billion in assets under custody or administration as of March 31, 2025. No AUM minimum. A good fit for advisors who want something less corporate than the Big 3 but more established than a pure startup.
How to pick the Right Custodian for your Firm
Here are the factors that actually matter when you’re evaluating a custodial relationship.
1. Minimum asset requirements
Some custodians want to see tens of millions in AUM before they’ll even take a meeting. Others will onboard you on day one. If you’re a new RIA, this is your first filter.
2. Pricing and fee transparency
Ask for the full fee schedule in writing. Look at ticket charges, cash sweep rates, margin rates, alternative investment fees, and any software costs. Then read the disclosures. The custodians who make this easy are usually the ones who have nothing to hide.
3. Tech Stack fit
Your custodian’s platform is going to touch everything: your CRM, your portfolio management system, your financial planning software, your billing.
Ask which of your existing tools integrate natively, which ones require middleware, and which ones won’t work at all. Advanced technology at the custodian level means nothing if it can’t talk to the rest of your advisor business.
4. Service Quality
This is the one to dig into. Ask the hardest question in the sales cycle: “If I call with a broken ACAT at 3pm on a Tuesday, how long until I get a real person on the phone?” Whatever the answer is, that’s the service level you’re buying. A good support team is the difference between a smooth business and a daily fire drill.
5. Retail Competition
Does the custodian have a retail division that’s actively marketing to the same clients you serve? Some advisors care deeply about this. Others don’t. Know where you land.
6. Investment Product Access
Make sure the custodian supports what you actually use: equities, mutual funds, ETFs, SMAs, alternatives, fixed income, international securities, and anything else your investment management process relies on. If you promise clients access to something your custodian can’t deliver, you’ve got a problem.
7. Track record and Reputation
How long have they been in the RIA model? Who do they serve now? What do their current advisors say? Your custodian becomes an extension of your fiduciary duty, so the institution’s track record matters.
As Jon Beatty, the COO of Advisor Services at Schwab, has told industry press: size matters less than fit. Bigger custodians offer more products and tools, but the right custodian is the one that serves your specific clients the way you want them served.
Should You use More than One Custodian?
The number of RIAs using two or more custodians climbed to 6,253 in 2024, roughly 27% of the market, and the number keeps growing. There are real reasons to consider it:
- Redundancy during tech outages (which do happen)
- Access to specialized capabilities: one provider for standard brokerage, another for alternatives, crypto, or international
- Leverage on fees when you can credibly move assets
- De-risking after the Schwab/TD Ameritrade merger, which showed advisors what forced repapering actually looks like
The trade-off is complexity. More systems to learn. More reconciliation work. More training for your support team. More integrations to maintain in your tech stack. If you’re a two-person firm, one custodian is probably right. If you’re a growing RIA with varied client needs, two might make sense.
Your Custodian Holds the Money. Your CRM Runs the Business.
Picking the right custodian is one of the biggest calls you’ll make. But it’s one decision in a bigger stack. Your custodian safeguards client assets. Your CRM runs everything else: the relationships, the workflows, the compliance trail, the client communication, the meeting prep, and the coordination across your team.
Here’s where a lot of firms go wrong. They pick a custodian carefully, then bolt on a generic CRM (Salesforce, HubSpot, something like that) and wonder why their business feels clunky. Generic CRMs were built for sales teams and call centers. They don’t understand households, service tiers, proactive touch schedules, 60+ relationship types, or the kind of meeting intelligence that actually helps you prep for a portfolio review.
Financial advisors need software built for the way RIAs actually work. That’s the idea behind Altitude CRM, the CRM built specifically for RIAs and independent advisors and their advisory firms. It bakes in Bill Good Marketing’s proven practice management methodology, pairs it with AI that understands client relationships, and adds meeting intelligence designed for annual reviews, discovery conversations, and planning sessions. It connects to your calendar, your email, and the tools you already use, so the client experience stays consistent from the first prospect meeting to the hundredth review.
If you’re going to spend weeks picking the right custodian, spend the same energy picking the tech stack that runs your advisor business every other minute of the day.
A Final Thought
The RIA custody market is more open than it was five years ago. The Big 4 still dominate, but real alternatives exist at every tier, from new RIAs looking for their first custodial relationship to billion-dollar firms evaluating a second provider.
Treat this decision like a multi-decade partnership, not a checkbox. Ask hard questions. Read the disclosures. Talk to current advisors who use the platform. The right custodian makes your business feel effortless. The wrong one shows up in your inbox every week.
You’ll know the difference within 90 days.
Frequently Asked Questions about RIA Custodians
An RIA custodian is an independent, regulated financial institution that holds client assets on behalf of a registered investment advisor. The custodian keeps the securities and cash, executes the trades the advisor places, settles transactions, and sends statements and tax forms to clients. The advisor handles the strategy and the relationship. The custodian handles the money. The Investment Advisers Act of 1940 requires this separation so advisors never touch client funds directly.
Charles Schwab. Schwab Advisor Services holds more than $5 trillion in RIA assets as of late 2025 and shows up as a custodian for over 58% of the 23,000+ RIA firms tracked by AdvizorPro. Schwab’s lead grew after the 2020 acquisition of TD Ameritrade.
Mostly indirectly. Custodians typically don’t charge RIAs a direct custody fee. Revenue comes from ticket charges on trades, cash sweep spreads (the difference between what the custodian earns on client cash and what it passes back), payment for order flow, margin lending interest, mutual fund revenue sharing, and markups on certain investment products. Clients pay these costs, just not as a line item.
Charles Schwab, Fidelity Institutional, BNY Pershing, and LPL Financial. Together they control the vast majority of RIA custodied assets in the US. Schwab is the clear leader, followed by Fidelity (3,300+ firms), BNY Pershing ($3 trillion+ in assets under custody or administration), and LPL Financial ($2.3 trillion in total brokerage and advisory assets).
Many do. Fidelity often looks for $50 million to $100 million in AUM before onboarding a new RIA. BNY Pershing typically targets firms with $100 million or more. Raymond James caters to larger firms, with new joiners averaging $600 million+ in assets. Schwab, Altruist, Axos Advisor Services, and Interactive Brokers generally have no AUM minimum, which makes them popular with new RIAs. Always ask upfront. Minimum asset requirements can be firm or flexible depending on the custodian and your growth story.
Most custodians don’t charge advisors a direct fee for holding client assets. The common cost layers are ticket or transaction charges on trades (often a few dollars each), cash sweep spreads on uninvested cash, margin interest on borrowed balances, and fees on certain mutual funds, alternatives, or in-house products. Some custodians also charge for premium software tiers or specialized services. Ask for the full fee schedule in writing and read the disclosures carefully. Fee transparency varies a lot across providers.
Focus on seven factors: minimum asset requirements, pricing and fee transparency, tech stack integration, service quality, whether the custodian has a retail division competing for your clients, investment product access, and the firm’s track record with RIAs like yours. The most revealing question to ask in any pitch is how long it takes to get a real person on the phone when something breaks. That answer tells you what you’re actually buying.
