IBKR pitches RIAs with a fee page and a promise

Interactive Brokers, the firm Thomas Peterffy launched in 1993, is recruiting RIAs with the weapon its institutional customers have seen all along: a public price list. Financial Planning reports that the company's landing page for advisory-firm owners carries the promise that IBKR will be 'your custodian, not your competitor,' links to current rates for commissions, fees, margin, interest and a stock-yield enhancement program, and puts the advisory side of the custody book at more than $100 billion in assets and hundreds of thousands of client accounts.

The market has noticed the momentum — shares are up 40% this year — but advisors tend to move for details that quarterly returns do not capture, and the fee schedule is the cleanest detail IBKR offers. Amanda McLean, the firm's director of sales for the institutional channel, describes a policy set that reads like a challenge to traditional custodians: no custody fees, no minimum-asset requirement and no ticket charges, and she told Financial Planning that IBKR has always been transparent about its offering and that advisors can come to the firm 'whether they're established or newly formed.'

McLean declined to give Financial Planning more specific metrics for its ongoing series on the channel's fees and business models, leaving the economics of the no-fee book unquantified. Pricing is what starts the conversation; service and operational record are what finish it.

IBKR's trading architecture is the other half of the recruiting asset: a single unified master account can trade across 170 global markets and 29 currencies, and the firm's website says its RIA accounts outperformed the S&P 500's 2025 gain by 2.67 percentage points. Those are useful claims for advisors with internationally mobile clients, but less obvious is how the engineering translates into day-to-day advisory work.

Cerulli Associates describes IBKR as an emerging custodian rather than a default wealth-management platform. Stephen Caruso, Cerulli's director of wealth management, says IBKR could make deeper inroads beyond its reputation as a trading-oriented platform by improving customer service and advisor-specific technology; the example he reaches for is Altruist, whose Hazel AI planning agent rolled out the week after Altruist agreed to sell to Vanguard at a reported price above $4 billion.

That benchmark is the right one for measuring a would-be RIA custodian, because independent advisors rarely leave large platforms for a lower price alone: they leave when a competing platform offers tools worth the move. IBKR can point to engineering depth, but the advisory layer is the part of the stack that remains to be proved.

The slogan lands at a time when, as this publication has argued, custody is no longer neutral. Schwab has said it will end referrals of under-$5 million clients to advisor-network firms in 2027, and Schwab and Fidelity have both pulled back from the tax trade, making the large custodians more obviously rivals to the advisors whose accounts they hold. IBKR's line is a direct answer: it will not be sitting on the other side of the client relationship.

The fee page is the strongest version of that argument, because transparent pricing strips the moving parts out of a decision that usually happens behind proposal sheets and renewal calls. But no custodian sells on price alone for long, and IBKR's decision not to publish service metrics leaves its core claim untested.

The account-opening process and the transfer desk will settle the question, since a modern custodian earns the relationship when clients arrive cleanly, statements read clearly and support answers on the first call. IBKR's bulked-up service teams are a promise in that direction; the numbers that would let an advisor compare them with the rest of the channel have not been published yet.

The next disclosure worth waiting for is the one McLean did not provide to Financial Planning: how many advisory firms have actually moved to IBKR, and how quickly their assets followed. That figure will tell whether the rates page is a recruiting document or the start of a real RIA platform; it is the number that would turn a transparent fee schedule into a documented service record.
