Interactive Brokers sees surge in trading activity in April
Interactive Brokers, a global leader in automated electronic trading, reported strong financial and operational results for April 2025, emphasizing continued growth in trading activity and client engagement.
- Chosen by 2 400+ local traders in the last 3 months.
- Traders earn on average 12% more per month vs other brokers.
According to the company’s press release, Daily Average Revenue Trades (DARTs) totaled 3.818 million, representing a 63% increase compared to April 2024 and a 10% rise over March 2025.
One of the key financial indicators was total client equity, which reached $588.1 billion — 28% higher year-over-year and 3% above the previous month. This signals a high client retention rate and a steady inflow of new users.
Credit activity and investor behavior
Despite a 9% month-over-month decline in margin loan balances, the total stood at $58.2 billion, still 15% higher than in April of the previous year — indicating continued interest in leveraged trading strategies.
Meanwhile, client credit balances rose to $132.8 billion, including $5 billion in FDIC-insured bank deposit sweeps. This figure reflects a 26% year-over-year increase and a 6% monthly growth, suggesting a more cautious investor stance and readiness to seize market opportunities.
Client base expansion and commission structure
Interactive Brokers’ client base expanded to 3.71 million accounts, up 32% compared to April 2024. This growth underscores the platform’s strong appeal among both retail and institutional traders.
In April, the average cleared commissionable order cost $2.75, including $2.16 for stocks, $3.63 for equity options, and $3.75 for futures.
Transparency, cost efficiency, and currency diversification
Financial transparency remains a core value for IBKR. The average all-in cost of U.S. Reg-NMS stock trades for IBKR PRO clients stood at 4.1 basis points in April, slightly above the 12-month average of 3.9 basis points. Total commissions and execution costs reached $212.4 million, with $159.7 million attributed to execution costs alone.
The company also noted that its GLOBAL currency basket, used for currency risk diversification, appreciated by 0.96% in April and 1.715% year-to-date, contributing modestly to comprehensive income.
Interactive Brokers continues to strengthen its position through automation, cost control, and transparency — a solid foundation for further growth amid evolving market dynamics and client expectations.
Earlier, Interactive Brokers reported a 19% revenue increase in Q1 2025.
