Founded in 1977 by billionaire financial pioneer Thomas Peterffy, Interactive Brokers has fundamentally transformed modern capital markets through relentless software automation, low-cost execution, and programmatic access. The firm provides sophisticated institutional investors, hedge funds, registered investment advisors (RIAs), proprietary trading firms, and active retail traders with direct access to trade stocks, options, futures, currencies, bonds, mutual funds, and exchange-traded funds across more than 150 electronic exchanges in 34 countries and 27 currencies from a single unified account. Operating with an extraordinary pre-tax profit margin exceeding 70%, Interactive Brokers serves over 3.1 million institutional and active client accounts managing more than $540 billion in client equity. Under the leadership of Chief Executive Officer Milan Galik and Founder & Chairman Thomas Peterffy, the company generates $5.15 billion in annual net revenue and $3.20 billion in net income, cementing its status as the world's most profitable and technologically advanced electronic brokerage.

Interactive Brokers operates a highly automated, low-overhead electronic direct-market-access brokerage model driven by two powerful economic engines: (1) Net Interest Income (~65% of net revenue), where the firm earns high spreads by collecting low-cost client cash balances and investing them in short-term US Treasury bills or lending them to margin borrowers at industry-leading benchmark-plus margin rates; and (2) Commissions and Execution Fees (~30% of net revenue), earned by routing trades across 150+ market centers globally using its proprietary SmartRouting algorithm, which continuously scans competing exchanges to deliver National Best Bid and Offer (NBBO) execution. By automating trade matching, margin risk evaluation, and account administration, Interactive Brokers maintains an ultra-lean global headcount of approximately 3,100 employees, producing extraordinary operating leverage and pre-tax margins exceeding 70%.
