The report showed that net revenue increased by 21% to $1.66 billion, up from $1.37 billion in the same quarter of 2024. Adjusted net revenues totaled $1.61 billion, reflecting continued momentum across key business lines. Income before income taxes increased to $1.31 billion, up 44% from the prior year’s $909 million, resulting in a robust pretax profit margin of 79%, compared to 67% a year earlier.
The company’s net interest income climbed 21% to $967 million, supported by higher securities lending activity, margin loans, and customer credit balances. Commission revenue also surged 23% to $537 million, driven by significantly higher trading volumes — up 67% in stocks and 27% in options, while futures trading fell slightly by 7%.
Operational efficiency and strong balance sheet
Interactive Brokers reported substantial operational efficiency, with general and administrative expenses falling 59% to $62 million, largely due to the non-recurrence of regulatory and consolidation-related costs from the prior year. Execution and clearing fees also decreased 21% following the SEC’s decision to reduce the Section 31 transaction fee to zero.
The firm’s balance sheet remains solid, with total equity reaching $19.5 billion, up from $16.6 billion at the end of 2024. The Board of Directors declared a quarterly cash dividend of $0.08 per share, payable on December 12, 2025, to shareholders of record as of December 1, 2025.
Customer accounts expanded 32% year-over-year to 4.13 million, while customer equity jumped 40% to $757.5 billion. Daily average revenue trades (DARTs) grew 34% to 3.62 million, underscoring the continued growth in user engagement and platform activity.
Strategic outlook and market position
Interactive Brokers’ results highlight the benefits of its automated trading infrastructure, diversified revenue streams, and strong global footprint. The company noted that its currency diversification strategy slightly reduced comprehensive earnings by $33 million, reflecting a minor 0.25% decline in the U.S. dollar value of its GLOBAL currency basket.
CEO Thomas Peterffy reaffirmed the firm’s commitment to providing advanced trading technology, global market access, and regulatory transparency. With rising client activity and expanding assets under custody, Interactive Brokers remains one of the most profitable and efficiently run brokers in the industry.
The company continues to attract both institutional and retail investors seeking low-cost, technology-driven trading solutions across more than 160 markets worldwide.
