Interactive Brokers Q2 Revenue Climbs to $1.9 Billion as Client Accounts Reach 5.2 Million

Interactive Brokers Group reported higher second-quarter profit and revenue on Tuesday, driven by growth in customer accounts, trading volumes and margin lending. The automated broker posted net revenue of $1.90 billion for the three months through June, up 28% from $1.48 billion a year earlier, while diluted earnings per share rose to $0.69 from $0.51. Pretax income came in at $1.46 billion, a 32% annual increase, with the pretax margin at 77%. The firm ended June with 5.19 million customer accounts, up 34% year-over-year, and customer equity reached $930.3 billion, up 40%.

Commission revenue rose 30% to $673 million, driven by higher customer trading, with options volume up 17%, stock volume up 14% and futures volume up 2%. Daily average revenue trades climbed 36% to 4.82 million. Net interest income, the largest revenue source, rose 23% to $1.06 billion, attributed to higher average margin loans and credit balances. Margin loans ended the quarter at $108.5 billion, up 67%, and customer credit balances rose 27% to $182.4 billion.

However, net interest margin slipped to 1.93% from 2.07% a year earlier as yields fell across interest-earning assets. The annualized yield on customer margin loans dropped to 4.10% from 4.67%, and the yield on segregated cash and securities fell to 3.32% from 3.86%. The pretax margin held at 77%, above the year-ago 75% but below the 79% reported in Q3 2025.

Interactive Brokers caters to active traders, financial advisors and institutions, a base that kept trading through the quarter. In contrast, Robinhood reported slower revenue growth in Q1, with net revenue up 15% and crypto trading volumes down. Interactive Brokers has added prediction-market contracts and AI trading tools from ChatGPT and Grok to maintain engagement. Commission per cleared order was little changed at $2.64, reflecting volume-driven growth.

The board declared a quarterly dividend of $0.0875 per share, unchanged from the prior quarter. Total equity stood at $22.3 billion at quarter-end. The firm’s GLOBAL currency basket strategy cut comprehensive earnings by $36 million as the dollar value of the basket fell about 0.21%. Reported net income was $1.34 billion, with $1.03 billion attributable to noncontrolling interests, leaving $312 million for common shareholders.
