Interactive Brokers’ October DARTs Rise 5%, Fall 4% Year Over Year

Interactive Brokers Group recorded 4.306 million daily average revenue trades (DARTs) in October, up 5% from September but down 4% from October 2025. The company listed its October metrics Nov. 2.

DARTs measure customer orders divided by the number of trading days in a period. October had 22 U.S. trading days, compared with 21 in September and 23 in October 2025. Annualized average cleared DARTs per client account were 163 in October.

Client accounts totaled 5.6776 million at October’s end, a 2% increase from September and a 34% rise from a year earlier. Client equity stood at $928.6 billion, down 4% month over month and up 19% year over year.

Margin loans reached $106.8 billion, up 2% from September and 31% from October 2025. Client credit balances totaled $180.5 billion, including $6.2 billion in FDIC program client credits. The balance fell 3% from September and rose 15% year over year.

The October metrics did not provide a separate count of crypto-related orders, so they do not show whether crypto activity contributed to the monthly increase in DARTs.
