Interactive Brokers Group Inc-CL A (NASDAQ:IBKR) reported fourth-quarter earnings for 2025 that surpassed analyst expectations, driven by robust growth in customer trading activity and net interest income. The electronic brokerage giant posted adjusted earnings per share (EPS) of $0.65 and adjusted net revenues of $1.67 billion for the quarter ended December 31, 2025.
Earnings and Revenue Performance Versus Estimates
The company’s results came in ahead of Wall Street’s forecasts. The reported figures represent a solid beat on both the top and bottom lines.
- Adjusted EPS: Reported at $0.65, beating the analyst consensus estimate of $0.603.
- Adjusted Net Revenue: Reported at $1.67 billion, exceeding the estimated $1.64 billion.
This performance marks a continuation of year-over-year growth. Compared to the fourth quarter of 2024, adjusted EPS rose from $0.51, while adjusted net revenues increased from $1.42 billion.
Market Reaction
Following the earnings release after the market close on Tuesday, January 20, 2026, IBKR shares experienced modest movement in after-hours trading. The stock was down approximately 0.7% in the extended session. This muted reaction suggests the market may have anticipated the strong results, as the stock had climbed over 13% in the month leading up to the report and was trading near a technical breakout level. The slight pullback could reflect profit-taking or a "sell-the-news" dynamic after the pre-earnings run-up, rather than disappointment with the fundamentals.
Key Financial and Business Highlights
The earnings beat was underpinned by strength across Interactive Brokers’ core business segments, reflecting healthy engagement from its growing client base.
Financial Highlights (Year-over-Year for Q4):
- Commission Revenue: Increased 22% to $582 million, fueled by higher customer trading volumes across options (+27%), futures (+22%), and stocks (+16%).
- Net Interest Income: Rose 20% to $966 million, driven by higher average customer margin loans and credit balances.
- Pretax Profit Margin: Expanded to 79%, up from 76% (adjusted) in the year-ago quarter, demonstrating the company’s operating leverage.
- Total Equity: Stood at $20.5 billion.
Business Metrics (Year-over-Year for Q4):
- Customer accounts grew 32% to 4.40 million.
- Customer equity increased 37% to $779.9 billion.
- Daily Average Revenue Trades (DARTs) rose 30% to 4.04 million.

The company also declared a quarterly cash dividend of $0.08 per share, payable in March 2026.
Forward-Looking Estimates
While the press release did not provide formal financial guidance for the coming quarters, analyst estimates offer a benchmark for future performance. For the first quarter of 2026, the consensus projects revenue of approximately $1.64 billion and EPS of around $0.57. For the full 2026 fiscal year, analysts are currently modeling sales of about $6.79 billion and revenue of $2.39 billion. Investors will likely listen for any commentary on these trends during the company’s earnings conference call.
Conclusion
Interactive Brokers delivered a strong finish to its 2025 fiscal year, exceeding earnings and revenue forecasts on the back of powerful growth in client activity and assets. The expansion of its high-margin business model is evident in the widening pretax profit margin. The initial market reaction appears neutral to slightly negative, potentially indicating the results were already priced in. The key question for investors moving forward will be whether the firm can sustain this momentum in client acquisition and engagement amid the prevailing market environment.
