Amid favorable market conditions and higher trading activity, Interactive Brokers Group IBKR recorded a surge in new account openings. The company’s Electronic Brokerage segment reported net new accounts of 135,900 for May. This marks a jump of 82% year over year and 30% from the last month.
Interactive Brokers’ total customer accounts at the end of May were 4.99 million, up 32% from May 2025 and 3% from April 2026.
Rising volatility across equities, options and global futures has triggered a strong wave of trading activity among both retail and institutional investors, benefiting Interactive Brokers. Uncertainty around the rate-cut path, higher Treasury yields, crude-oil swings tied to U.S.-Iran diplomacy, elevated equity valuations, AI-capex concerns and broader macro-driven positioning have supported heavier trading volumes, keeping IBKR’s active, high-frequency client base highly engaged.
In addition to increased trading activities, factors that have been driving growth in IBKR’s client base are the brokerage firm’s competitive pricing and low-fee structure, attractive margin features, continuous product innovation, streamlined onboarding and an efficient operating model.
Supported by the company’s efforts to diversify its product suite and develop proprietary software to automate broker-dealer functions, along with its solid Daily Average Revenue Trade (DART) numbers, its revenues are expected to increase. Over the last five years (2020-2025), IBKR’s total net revenues witnessed a compound annual growth rate of 22.8%, with momentum continuing in the first quarter of 2026.
