**Interactive Brokers (IBKR) is scheduled to report third-quarter 2026 results after the close on October 15, with consensus estimates at $0.67 EPS and $1.86 billion revenue.** Trader sentiment favoring a miss at 65% implied probability reflects recent moderation in key activity metrics, including September daily average revenue trades rising just 6% year-over-year while client accounts grew 35% to 5.576 million. Downward revisions to EPS estimates over the past 30 days, combined with softer sequential trading volumes, have tempered expectations despite strong prior-quarter beats and expanding client equity. Net interest income and margin trends remain supportive, but the earnings catalyst and any commentary on volume sustainability will likely drive near-term repricing.
