Recent moves
Interactive Brokers profit jumps, dividend nearly doubles
The move
Interactive Brokers reported third-quarter diluted earnings of $0.69 per share, up from $0.59 a year earlier, on GAAP net revenue of $1.91 billion, up from $1.66 billion. Commission revenue rose 12% to $602 million and net interest income climbed 19% to $1.15 billion. The company raised its quarterly dividend to $0.15 per share from $0.0875. Founder Thomas Peterffy also said in a CNBC interview that customers remain wary of autonomous AI trading tools even as the brokerage expands access to them.
Why it matters
It shows one of the largest retail and institutional brokerages still growing briskly even as rate cuts loom, with client caution about AI trading tools acting as a check on how fast that technology spreads through markets.
The bear case
Stock trading volume fell 24% from a year earlier, so some of the revenue strength is coming from interest income and fees rather than client trading activity.
What to watch
Whether AI-trading adoption among Interactive Brokers clients picks up in next quarter's results.
Interactive Brokers raises its dividend 71%
The move
Interactive Brokers reported third-quarter 2026 revenue of $1.91 billion and diluted EPS of $0.69, both up from a year earlier, in results released October 15. The board raised the quarterly dividend from $0.0875 to $0.15 per share.
Why it matters
Customer margin loans climbed 36% to $105.2 billion and net interest income rose 19%, signs that trading and borrowing activity at the brokerage stayed strong even as commission revenue cooled from the second quarter.
The bear case
Commission revenue fell from $673 million in the second quarter to $602 million in the third, as daily trading volume slowed from its prior pace.
What to watch
Whether trading volumes pick back up as the rest of Q4 earnings season unfolds.
