**Interactive Brokers (IBKR) reports Q3 2026 results on October 15, with trader-implied odds of 65% for an earnings beat reflecting the broker’s recent track record and robust client metrics.** In Q2, IBKR delivered EPS of $0.69, exceeding consensus by 5–13%, alongside 28% revenue growth driven by higher commissions and net interest income. September brokerage data showed client accounts rising 35% year-over-year to 5.576 million, client equity reaching $964.7 billion (+27%), and margin loan balances surging 36%, supporting interest revenue while DARTs increased 6% annually. These trends, combined with a history of margin expansion above 70%, underpin consensus estimates around $0.67–$0.71 EPS, though sequential moderation in trading activity introduces modest uncertainty ahead of the release.
