IBKR's Customer Accounts Grow in August 2025: What's Behind it?

Amid a favorable trading backdrop, Interactive Brokers’ IBKR Electronic Brokerage segment reported a 32% year-over-year rise in total customer accounts in August 2025. Compared with the previous month, customer accounts grew 2% to 4.05 million.

Net new accounts in August were 96,100, up 44% year over year and 4% from July 2025. Total client Daily Average Revenue Trades (DARTs) were 3,488,000, representing a 29% increase from August 2024 but a marginal decline from July 2025.

Along with heightened market volatility and increased client participation, factors that drove the rise in customer accounts include targeted product innovations, efficient onboarding, global expansion and increased visibility via IBKR’s strategic moves like the stock split and S&P 500 inclusion.

Interactive Brokers’ continued efforts to diversify its product suite and develop proprietary software to automate broker-dealer functions, along with the company’s solid DART numbers, have been aiding top-line growth. Over the last five years (2019-2024), the company’s total net revenues witnessed a compound annual growth rate of 21.8%, with the upward momentum continuing in the first half of 2025.

Given its technological superiority, IBKR’s revenues are expected to continue to improve in the near term, supported by higher client acquisitions. The Zacks Consensus Estimate for the company’s 2025 and 2026 revenues is $5.68 billion and $6.03 billion, indicating year-over-year growth of 8.8% and 6.2%, respectively.
