Interactive Brokers stock sees October activity rebound despite yearly dip
Published on 11/06/2026 at 16:24 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWSOctober activity and growth drivers
- Interactive Brokers reported 4.306 million daily average revenue trades in October, up 5% from September but down 4% year over year.
- Client accounts reached 5.678 million, while margin loans rose to 106.8 billion US dollars.
- Third-quarter revenue and net interest income increased year over year, although the pretax margin narrowed slightly.
Interactive Brokers released its October operating figures on Monday, November 2, adding a fresh read on customer growth, trading activity and margin lending. Zacks reported on Friday, November 6, that daily average revenue trades recovered from September but remained below the year-earlier level.
Total client DARTs reached 4.306 million in October, 5% above September and 4% below October 2025, according to Zacks. The figures point to improving sequential activity, but they also show that trading volumes have not fully regained last year's pace.
Accounts and lending remain supportive
Client accounts rose 34% year over year to 5.678 million. Margin loan balances increased 31% to 106.8 billion US dollars, while client credit balances climbed 15% to 180.5 billion US dollars. Client equity reached 928.6 billion US dollars, 19% above the year-earlier level.
The operating mix gives investors two contrasting signals. Account additions and lending balances support the brokerage's interest income and future transaction potential, while the year-over-year DART decline leaves trading-driven revenue exposed to market participation.
Third-quarter results set the backdrop
Interactive Brokers reported third-quarter 2026 GAAP net revenue of 1.914 billion US dollars for the period ended September 30, up from 1.655 billion US dollars a year earlier. The company reported diluted earnings per share of 0.69 US dollars, while adjusted diluted earnings per share was 0.67 US dollars. Net interest income rose 19% to 1.154 billion US dollars, according to the company's announcement carried by Financial Times.
