In the competitive arena of RIA custody, Interactive Brokers (IBKR) is carving out a niche by appealing to financial advisors with a straightforward pitch: low fees, attractive cash yields, and a powerful global trading platform. While the firm is often recognized for its automated execution and technology, its recent efforts to win over registered investment advisors (RIAs) highlight a strategic push to expand its footprint in the wealth management channel.
A Custodian That Positions Itself as a Partner, Not a Competitor
Interactive Brokers’ landing page for RIA owners speaks directly to advisors’ concerns, emphasizing a philosophy of “your custodian, not your competitor.” The firm highlights its transparent pricing model, which includes no custody fees, no minimum asset requirements, and no ticket charges. This approach contrasts with larger rivals that may negotiate opaque pricing or monetize client cash through low-yield sweeps. IBKR also promotes competitive interest on client cash, up to 3.13% USD, and a stock-yield enhancement program.
Amanda McLean, IBKR’s director of sales for institutional clients, underscores the firm’s commitment to advisors. “We’ve always been very transparent about our offering,” she says. “Essentially, advisors can come to us in whatever part of the business cycle—whether they’re established or newly formed—and we’ll engage with them.” The firm has worked with RIAs for 25 years, but has intensified its focus on service teams for advisors over the past decade and a half. Last year, it launched a dedicated team for RIA transitions.
Leveraging Global Technology and Growth
IBKR’s value proposition extends beyond pricing. Advisors gain access to trading in 170 global markets across 29 currencies through a single unified master account. The firm also points to a record of “RIA overperformance at IBKR,” claiming that its RIA clients outperformed the S&P 500 by 2.67 percentage points in 2025. This combination of technology and performance is designed to help advisors grow their practices.
Stephen Caruso, director of wealth management at Cerulli Associates, views IBKR as “an emerging custodian” with potential to make deeper inroads among advisors. He notes that the firm’s reputation as a “trading-oriented platform” is evolving through improved customer service and advisor-specific tools. Caruso suggests that IBKR’s focus on cash yields could be a “contributing factor” to its expansion, especially as some smaller firms express dissatisfaction with larger custodians like Charles Schwab, Fidelity, and BNY Pershing. The trend toward multi-custodian arrangements also opens doors for IBKR.
“They still have a ton of room to grow in the RIA market,” Caruso says. “There’s opportunity out there. Over the years, we’ve said that custody became an oligopoly in a lot of ways.”
Wall Street’s View: Growth at High Margins
While equity analysts are more focused on IBKR’s broader developments—such as a collaboration with South Korean firm Daol Investment & Securities and a new prediction-market interface—they also recognize the RIA channel’s potential. In June, Steven Chubak of Wolfe Research initiated coverage with a note titled “The Gospel According to Peter(ffy),” praising IBKR’s global footprint and sustainable growth.
“IBKR has built one of the only brokerage platforms with a true global footprint and a demonstrated ability to sustain its growth at high incremental margins,” Chubak wrote. He projected ~25% long-term account growth, citing the firm’s unmatched geographic reach and access to channels beyond individual investors, including introducing brokers, prime brokerage, and RIAs. Chubak’s team later raised earnings estimates following strong second-quarter results.
On a July 21 earnings call, CEO Milan Galik echoed this optimism, noting growth across all regions and account types. “Whether it’s financial advisors, introducing brokers, direct accounts—we are pleased with our growth across the board,” he said.
Differentiating from the Giants
IBKR’s recruiting materials take direct aim at competitors, stating that most custodians run their own advisory businesses, sell proprietary products, and operate referral networks. In contrast, IBKR claims to do none of these things. “Interactive Brokers has no in-house advisory team. No proprietary wealth management arm. No referral network. No proprietary products,” the page reads. “Our only business is giving you the technology, pricing, and global market access to run your practice on your terms.”
McLean emphasizes that the firm’s strategy is not solely about being the cheapest option. “It’s not just about having the lowest fees,” she says. “It’s about making an offer that is compelling, so that you as an advisor can have enhanced performance and you can think about growing your assets.”
As IBKR continues to evolve its platform and service offerings, it remains to be seen whether it can translate its low-cost, high-tech appeal into significant RIA market share. But for now, the firm is betting that transparency, global access, and a non-competing stance will resonate with advisors seeking an alternative to the industry’s dominant custodians.
