Interactive Brokers Group, Inc. Financial Overview 2021–2025

Updated Jul 10, 2026

Interactive Brokers Group achieved a staggering 77%a pretax profit margin in FY2025, reflecting exceptional cost control alongside aggressive global expansion. This elite profitability underscores the central investment thesis: a highly automated, low-cost electronic brokerage model that captures massive operational leverage as global trading volumes and customer cash balances rise.

The company’s growth trajectory has been relentless. Total net revenues more than doubled, climbing from $2.714 billion in FY2021 to $6.2 billionb in FY2025. This expansion was heavily fueled by an explosion in net interest income, which reached $3.6 billion in FY2025 on the back of expanded margin loans and customer credit balances. Active client acquisition compounded this financial success. By the end of FY2024, over 85% of new customers originated outside the U.S., driving total accounts to 3.337 million. As institutional interest accelerated following the company's addition to the S&P 500 Index in August 2025, management executed a four-for-one stock split to improve share accessibility.

Despite evolving central bank policies and mixed equity market conditions, the underlying balance sheet remains highly resilient. Total equity expanded to $19.5 billionc by the close of Q3 2025. Rewarding this sustained top-line acceleration and strict margin discipline, the market valued the stock at $64.31 per share, trading at a multiple of 29.0x earnings at the close of FY2025.

Recent Developments (Q4 2025 and Q1 2026)

Through Q4 2025 and Q1 2026, Interactive Brokers maintained momentum by diversifying revenue streams, capitalizing on rising fixed-income trading and sustained market volatility. On April 29, 2026, shareholders elected all ten director nominees—with founder Thomas Peterffy securing 88.11% support—and extended the stock incentive plan through April 24, 2037. Notably, corporate proposals faced an aggregate of 58,060,145 non-votes.

Bulls argue that expanding fixed-income capabilities creates a durable transaction revenue base capable of offsetting potential interest income declines. Conversely, bears warn that premium pricing leaves little room for error if retail engagement cools. As of May 7, 2026, the stock commanded a steeper valuation of $83.71d per share, pushing its market capitalization to $21.4 billion at a 37.7x trailing earnings multiple on an annual EPS of $2.22.

What to watch: fixed-income trading volume trends; shifts in customer margin utilization rates.
