Surge in Trading Volumes and Client Equity

Interactive Brokers reported an average of 3.864
million daily revenue trades in September, reflecting a 47% increase compared
to the same month last year and an 11% rise from August 2025.

This jump underlines a rising engagement level among
traders using IBKR’s automated platform. Alongside this, client equity soared
to $757.5 billion, marking a 40% year-on-year increase and a 6% rise
month-over-month, highlighting growing investment inflows and retained wealth
on the platform.

Client margin loan balances rose to $77.3 billion, up
39% from last year and 8% from the previous month, indicating that traders are
leveraging more capital for their positions. Credit balances, including $6.2
billion in insured bank deposit sweeps, also climbed by 33% annually to $154.8
billion.

Expanding Client Base and Trading Activity

The total number of client accounts reached 4.127
million, increasing 32% compared to September 2024 and growing 2% relative to
August.

The net addition of new accounts was 111,900 in

broker with nearly 39,000 accounts and $413.5 million in assets, the reported
net growth adjusted to 73,100 accounts.

Interactive Brokers expects a further closure of
around 2,900 accounts linked to this broker withdrawal by early October.
Despite this, the average cleared daily trades (DARTs) per client was 203,
showing sustained average activity across the client base.
