The headline numbers were underpinned by a dramatic expansion in pretax profit margin, which widened to 79% from 67% in Q3 2024, a result of both surging top-line growth and a sharp drop in non-interest expenses to $343 million from $456 million. Commission revenue climbed 23% to $537 million as customer stock trading volumes surged 67%, while net interest income rose 21% to $967 million on stronger securities lending and higher margin loan balances. Customer accounts grew 32% to 4.13 million and customer equity expanded 40% to $757.50 billion, signaling broad platform momentum. The results have drawn growing institutional interest in the post-split shares, following IBKR's four-for-one stock split in June 2025. The board declared a quarterly dividend of $0.08 per share.

Key Takeaways

  • Commission revenue increased 23% on higher customer trading volumes with stock volumes up 67% and options up 27%
  • Net interest income grew 21% driven by stronger securities lending activity and higher average customer margin loans and credit balances
  • General and administrative expenses decreased 59% primarily from non-recurrence of $88 million in legal/regulatory charges and $12 million European consolidation costs
  • Execution, clearing and distribution fees decreased 21% due to SEC Section 31 fee rate reduction to zero and greater exchange liquidity rebates
  • Customer accounts grew 32% to 4.13 million
  • Customer equity increased 40% to $757.5 billion
  • Total DARTs increased 34% to 3.62 million
