Interactive Brokers’ Stock Jumps as Q2 Revenue and Income Beat Street Estimations

Interactive Brokers (Nasdaq: IBKR) generated $516 million in commission revenue in the second quarter of 2025, marking a 27 per cent year-over-year increase. The broker’s net quarterly revenue came in at $1.4 billion, mainly driven by interest income.

IBKR Beats the Streets

The Connecticut-headquartered broker ended the quarter with net income of over $1 billion, representing a 24.3 per cent yearly increase. Earnings per share stood at $0.51.

Both revenue and income exceeded market expectations, which were estimated at $1.33–$1.36 billion and $0.45–$0.47 per share, respectively.

These results helped Interactive Brokers push its quarterly pre-tax profit margin to 75 per cent—both reported and adjusted—compared to 72 per cent and 73 per cent in the previous year.

The strong quarterly performance also lifted IBKR’s stock price. In after-hours trading, IBKR shares jumped over 4.51 per cent, reaching a new all-time high of over $62.

A Growing Customer Base

The rise in commission revenue aligns with a growing number of clients on the brokerage platform. At the end of June, the platform had 3.87 million customer accounts, up 32 per cent year over year.

The broker also revealed that customer trading volumes rose across asset classes: stocks by 31 per cent, options by 24 per cent, and futures by 18 per cent. It executed a total of 248,587 trades in the quarter, a 4 per cent increase quarter-over-quarter.

Furthermore, customer equity on the platform increased by 34 per cent to $664.6 billion, while total daily average revenue trades (DARTs) climbed by 49 per cent to 3.55 million.
