Interactive Brokers stock tracks October rebound as accounts rise 34%

Interactive Brokers reported stronger sequential trading activity in October, while customer growth and margin lending continued to advance. The figures released on Monday, November 2, and carried by Morningstar show a mixed operating picture for the automated broker.

Accounts expand as trading recovers

Daily Average Revenue Trades reached 4.306 million in October, 5 percent above September but 4 percent below October 2025. The sequential rebound points to improved client activity, although the annual comparison shows that transaction volumes had not fully regained their prior-year pace.

Client accounts rose to 5.678 million at the end of October, an increase of 34 percent from a year earlier and 2 percent from September. That expansion gives Interactive Brokers a larger base from which to generate future order flow, even if monthly trading activity remains sensitive to market participation.

Client margin loan balances increased to 106.8 billion US dollars, up 31 percent year over year and 2 percent month over month. Client credit balances reached 180.5 billion US dollars, including 6.2 billion US dollars in insured bank deposit sweeps. The credit balance rose 15 percent from the prior year but declined 3 percent from September.

Balance growth offsets softer equity

Ending client equity stood at 928.6 billion US dollars, 19 percent higher than a year earlier but 4 percent below the previous month. The combination of rising accounts and margin balances with lower monthly client equity suggests that customer acquisition and financing demand remained supportive, while asset levels still moved with market conditions.

Interactive Brokers also reported 163 annualized average cleared DARTs per client account. The average commission per cleared commissionable order was 2.46 US dollars, including exchange, clearing and regulatory fees. For IBKR PRO clients, the company said the total cost of executing and clearing US Reg.-NMS stocks in October was about 1.1 basis points of trade money against a daily VWAP benchmark.

For investors, the October update leaves two signals in focus. A larger account base and higher margin lending can broaden the earnings base, but the year-over-year decline in DARTs shows that transaction-driven revenue still depends on sustained engagement and market activity. The next monthly metrics update should clarify whether the October rebound continues.
