- Interactive Brokers expanded its customer base and margin lending in October.
- Trading activity improved from September but remained below the prior-year level.
- Investors will watch whether account growth converts into stronger activity and commission revenue.
Interactive Brokers Group's October operating figures show continued expansion in customers and margin lending, while trading activity remained below the year-earlier level. The company published its monthly brokerage metrics on Monday, November 2, according to its investor relations page.
Accounts expand faster than trading
Client accounts reached 5.678 million at the end of October, up 34 percent from October 2025 and 2 percent from September. That wider customer base gives the broker more potential to generate commissions, interest income and other service revenue when market participation strengthens.
Daily average revenue trades rose 5 percent from September to 4.306 million. They were nevertheless 4 percent below October 2025, leaving transaction-driven revenue dependent on a sustained recovery in client activity.
Margin lending supports revenue mix
Ending client margin loan balances increased 31 percent year over year and 2 percent month over month to 106.8 billion US dollars. Client credit balances rose 15 percent year over year to 180.5 billion US dollars, including 6.2 billion US dollars in insured bank deposit sweeps.
Client equity reached 928.6 billion US dollars, 19 percent above the prior-year level but 4 percent below September. The figures point to a growing asset and lending base, while also showing that monthly balances remain sensitive to market conditions.
