Interactive Brokers Posts Stellar Quarterly Performance Fueled by Client Surge

Interactive Brokers has delivered a powerful quarterly report, showcasing results that significantly outpaced market forecasts. The electronic brokerage firm demonstrated remarkable strength across its key business segments, driven by a substantial expansion of its client base and heightened trading activity.

Earnings and Revenue Exceed Expectations

For the third quarter of 2025, Interactive Brokers reported a diluted earnings per share (EPS) of $0.59. On an adjusted basis, EPS came in at $0.57, soundly beating analyst projections of $0.49. The company’s net revenue climbed 21.2 percent to reach $1.66 billion, reflecting robust performance in its core operations.

A breakdown of the revenue streams reveals solid growth across the board:
* Commissions: Increased by 23 percent to $537 million.
* Net Interest Income: Grew by 21 percent to $967 million.

This balanced growth underscores the company’s operational resilience and its ability to thrive in a competitive brokerage landscape.

Unprecedented Client and Trading Momentum

A central theme of the report was explosive client acquisition. The total number of customer accounts surged by an impressive 32 percent, reaching 4.13 million. This influx of new users translated directly into significantly higher market activity, as evidenced by sharp increases in trading volumes:
* Equity Trades: Jumped 67 percent.
* Options Contracts: Rose 27 percent.
* Daily Average Revenue Trades (DARTs): Grew 34 percent to 3.62 million.

Should investors sell immediately? Or is it worth buying Interactive Brokers?

This powerful combination of client growth and elevated engagement provides a strong, sustainable foundation for future revenue.

Strategic Moves and Institutional Confidence

The company’s growth trajectory and future prospects are attracting significant attention from major institutional investors. STRS Ohio, for instance, dramatically increased its stake in the second quarter by a staggering 1,369.2 percent, bringing its holding to 132,459 shares. This substantial investment signals deep confidence in the firm’s long-term strategy.

Strategically, Interactive Brokers continues to expand its product ecosystem. The recent launch of the Karta Visa Card offers clients the ability to spend globally without incurring foreign transaction fees. Furthermore, a partnership with HSBC on the HSBC WorldTrader platform is strategically aimed at capturing a larger share of the international accounts market.

Market Analysts Maintain Bullish Outlook

The consensus among market experts remains positive, with an average rating of “Moderate Buy” and a price target of $72.08. In a notable show of confidence, Goldman Sachs reaffirmed a “Buy” rating on the stock in October, setting a price target of $91.00. These assessments reflect a widespread belief that Interactive Brokers is well-positioned to maintain its current growth trajectory.
