The June uptick marks a month-over-month (MoM) improvement in DARTs following two consecutive monthly declines, down 11% in May and 4% in April. YoY growth has consistently remained above 40% in recent months.

Other key brokerage metrics for June included:  

• Ending client equity totaled $664.6 billion, up 34% from the previous year and 6% higher than the prior month.
• Ending client margin loan balances stood at $65.1 billion, reflecting an 18% YoY increase and 6% MoM growth.
• Ending client credit balances were $143.7 billion, including $5.8 billion in insured bank deposit sweeps, up 34% from June 2024 and 7% from May 2025.
• Client accounts grew to 3.866 million, representing a 32% YoY increase and 2% MoM growth.

Additional performance indicators included an annualized average of 195 cleared DARTs per client account and an average commission per cleared commissionable order of $2.54, including exchange, clearing, and regulatory fees.

Interactive Brokers, a leading global automated electronic broker, expanded its global footprint with the opening of a new office in the Dubai International Financial Centre (DIFC) last October. The branch operates under a Category 4 license issued by the Dubai Financial Services Authority (DFSA).

In contrast, the company’s Hong Kong branch faced regulatory scrutiny earlier this year. In April, Interactive Brokers Hong Kong Limited was fined $4.2 million by the Securities and Futures Commission (SFC) for breaches related to the handling of client assets.
