Interactive Brokers Q3 Earnings Match Estimates as Revenue Beats but Shares Slip 2% After Hours

Interactive Brokers Group reported third-quarter 2026 results after the close on October 15, delivering a mixed picture that sent shares down roughly 2% in after-hours trading. GAAP net revenues came in at $1.91 billion, up 15% year over year and ahead of the $1.86-1.89 billion consensus, while adjusted revenue of $1.87 billion fell just short of the $1.89 billion estimate. Adjusted earnings per share of $0.67 matched most estimates, with GAAP diluted EPS of $0.69, compared with $0.59 on a GAAP basis and $0.57 adjusted in the year-ago quarter.

Net interest income rose 19% year over year to $1.15 billion, driven by higher average customer margin loans and customer credit balances. Commission revenue grew 12% to $602 million on an 18% increase in daily average revenue trades, which reached 4.27 million. Customer accounts expanded 35% year over year to 5.58 million, and customer equity climbed 27% to $964.7 billion. Customer margin loans increased 36% to $105.2 billion and customer credits rose 20% to $186.2 billion. Pretax profit margin stood at 78%, down 100 basis points year over year, with adjusted pre-tax income of $1.45 billion. Other income fell 18% year over year to $70 million, partly reflecting currency diversification effects including a $40 million gain in other income offset by a $44 million loss in other comprehensive income.

The company raised its quarterly dividend by 71.4% to $0.15 per share from $0.0875 per share, and outlined a $0.60 annual dividend plan. Interactive Brokers also announced plans to expand its autonomous AI trading rollout. Despite the headline beat on reported revenue, the after-hours decline reflected the adjusted revenue and EPS shortfall, along with a slowdown in customer stock trading noted by analysts, even as futures trading showed growth.
