Interactive Brokers Group released its October brokerage metrics on Monday, November 2, 2026. The figures show a broker adding customers and margin exposure while trading activity remained softer than a year earlier. The release was carried by Morningstar from Business Wire.

Accounts and lending lead growth

Client accounts reached 5.678 million at the end of October, an increase of 34 percent from October 2025 and 2 percent from September. The expansion gives Interactive Brokers a broader base for future order flow and balances, even as monthly activity remains sensitive to market participation.

Client margin loan balances rose to 106.8 billion US dollars, gaining 31 percent year over year and 2 percent month over month. The increase points to stronger financing demand and can support interest-related revenue, although lending balances also depend on market levels and client positioning.

Client equity stood at 928.6 billion US dollars, 19 percent above the prior year but 4 percent below September. Client credit balances reached 180.5 billion US dollars, including 6.2 billion US dollars in insured bank deposit sweeps, up 15 percent annually and down 3 percent from the previous month.

Trading recovers but lags last year

Daily average revenue trades rose 5 percent from September to 4.306 million, but they were 4 percent below October 2025. The combination of stronger sequential activity and weaker annual momentum leaves the near-term earnings contribution from transaction-related revenue dependent on whether client engagement continues to improve.

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 trading US Reg-NMS stocks, the company said the October all-in execution and clearing cost was 1.1 basis points against a daily VWAP benchmark, compared with 2.4 basis points for the rolling 12 months.

What the figures mean for investors

The monthly release reinforces two elements of the Interactive Brokers model: account growth and client financing are expanding, while order activity has not yet matched the prior year's pace. Rising margin loans may cushion weaker trading volumes, but the mix also increases exposure to market conditions and credit demand.
