Interactive Brokers Reports Strong March 2026 Metrics

Interactive Brokers Group, Inc. has released its key operating metrics for March 2026, reporting strong year-over-year growth across major performance indicators. However, some figures showed a slight decline compared to the previous month. The brokerage recorded 4.329 million Daily Average Revenue Trades (DARTs) during March, marking a 25% increase from March 2025; however, the figure came in 1% lower than February 2026, reflecting a modest sequential dip in trading activity. 

Meanwhile, client equity reached $789.4 billion at the end of the month, representing a significant 38% increase compared to the same period last year. Nevertheless, the total declined by 4% from February levels, indicating short-term market fluctuations or portfolio adjustments by investors. Similarly, client margin loan balances stood at $86.0 billion, increasing 35% year-over-year, yet slipping 4% every month, suggesting a slight reduction in leveraged trading positions.

In contrast, client credit balances continued to show resilience and growth momentum. The firm reported $168.8 billion in client credit balances, including $6.5 billion held in insured bank deposit sweeps, which reflects a 35% increase from the prior year and a 4% rise from the previous month. This upward movement highlights continued inflows and stronger cash positions among clients despite mixed trading activity trends. 

Furthermore, Interactive Brokers expanded its global client base, with total client accounts reaching 4.754 million. This figure represents a 31% increase compared to March 2025 and a 2% gain from February 2026, underscoring sustained customer acquisition and platform adoption. At the same time, the average commission per cleared commissionable order stood at $2.74, inclusive of exchange, clearing, and regulatory fees, maintaining cost efficiency for traders. 

Overall, the March 2026 metrics demonstrate that Interactive Brokers continues to deliver robust annual growth while experiencing minor month-over-month variations. The combination of rising client accounts, higher equity levels, and steady credit balances suggests that the firm remains well-positioned in the competitive electronic trading landscape, even as short-term trading volumes fluctuate.
