Interactive Brokers is an automated electronic brokerage that executes, clears, and settles trades for institutional and individual customers globally. The firm offers access to stocks, options, futures, forex, bonds, ETFs, mutual funds, cryptocurrencies, and other asset classes across more than 170 exchanges in 40 countries — all from a single platform. Interactive Brokers targets sophisticated, active investors and serves hedge funds, RIAs, introducing brokers, and individual traders. As of FY25, the firm had approximately 4.4 million customer accounts across 200+ countries. Revenue comes primarily from two sources: commissions (~35% of net revenues), driven by trade volumes across products, and net interest income (~60% of net revenues), earned on segregated customer cash, margin loans, and securities lending. The business model carries significant operating leverage — most brokerage and compliance functions are automated through proprietary software, keeping headcount costs low. Interactive Brokers grows almost entirely organically, relying on low costs and broad market access rather than promotional incentives. Key growth vectors include international expansion (the majority of new accounts come from outside the U.S.), the introducing broker channel, overnight trading, cryptocurrency, and ForecastEx, an owned CFTC-registered prediction market exchange. Interactive Brokers has also applied for a U.S. National Trust Bank charter, primarily to enable custody of mutual fund and ETF assets.
