Interactive Brokers (IBKR.US), a leading electronic trading firm, has reported its financial performance for the third quarter of 2025. According to the earnings release, Interactive Brokers achieved a net revenue of $1.66 billion in Q3, marking a 21% increase from $1.365 billion in the same period last year, surpassing market expectations of $1.505 billion. The adjusted earnings per share stood at $0.57, up from $0.40 a year ago, and exceeding the market estimate of $0.54. The rise in commission revenue by 23% year-on-year to $537 million was attributed to an increase in client trading volumes. Trading volumes for stocks and options rose by 67% and 27%, respectively, while futures trading volume saw a decrease of 7%. Net interest income also increased by 21%, reaching $967 million, driven by enhanced securities lending activities as well as a rise in average margin loans and credit balances. Other fees and service revenue declined by 8% to $66 million, primarily due to a $12 million decrease in risk exposure fees, partially offset by a $3 million increase in FDIC assessment fees. Execution, clearing, and distribution costs fell by 21% to $92 million, attributed to reduced regulatory fees and increased liquidity rebates from certain exchanges resulting from higher stock and options trading volumes. Furthermore, the board of Interactive Brokers declared a quarterly cash dividend of $0.08 per share, payable on December 12, 2025, to shareholders recorded as of December 1, 2025. As of the time of reporting, Interactive Brokers' stock fell over 2% in after-hours trading on Thursday.
