Interactive Brokers courts RIAs with low fees, global tools

Interactive Brokers is actively courting registered investment advisers by highlighting a custody business that holds more than $100 billion in RIA assets. The firm advertises no custody fees, no minimum assets under management, no ticket charges and access to 170 markets across 29 currencies. Across all affiliates Interactive Brokers reports more than $903 billion in client assets.

Amanda McLean, director of sales, institutional, described the firm’s focus on advisory clients and noted expanded service teams aimed at RIAs over the past decade. McLean said the company is “very committed as a fiduciary” and that the platform integrates with many third-party providers through automated connections to custody and portfolio tools.

The firm points to a unified master account that allows trading across multiple markets and currencies and to published rates for commissions, margin and a stock-yield enhancement program. Interactive Brokers advertises a competitive cash sweep yield of up to 3.13% in U.S. dollars and reports that RIA accounts at the firm outperformed the S&P 500 in 2025 by 2.67 percentage points. The company also established a dedicated RIA transition team last year to assist firms moving custody and accounts.

Industry consultants and analysts say the firm has room to increase its share of the RIA channel while facing a custody market concentrated among several large providers. Stephen Caruso of Cerulli Associates called Interactive Brokers “an emerging custodian” and pointed to opportunities if the company develops advisor-specific service and technology. Wolfe Research analyst Steven Chubak initiated coverage and projected sustained account growth, noting that the firm has already absorbed many upfront international expansion costs.

On an analyst call, CEO Milan Galik listed financial advisors among channels that are contributing to the company’s global account growth. The firm has announced partnerships overseas and released new product interfaces, including a unified prediction-market feature introduced in May and a recent collaboration with a South Korean securities firm.

Interactive Brokers stresses published, transparent pricing and contrasts that with negotiated deals and low-yield cash sweep arrangements at some competitors. The company’s materials state it does not operate an in-house advisory business, proprietary wealth arm, referral network or proprietary products, and that its primary business is providing trading technology, pricing and market access to advisory firms.
