Interactive Brokers, an automated global electronic broker and Nasdaq-listed financial services group, has revealed that both its individual and hedge fund clients outperformed the S&P 500 Index on average in 2025.
The results published by the broker show that in 2025 its individual clients achieved an average return of 19.20%, compared with the 17.9% return delivered by the S&P 500 Index.
Over the same period, hedge fund clients using Interactive Brokers recorded average returns of 28.91%, outperforming the benchmark by approximately 11 percentage points.
The firm attributes this performance to several core features of its offering. Clients can earn interest of up to USD 3.14% on uninvested cash balances, allowing capital to remain productive even when not fully deployed. In addition, margin rates as low as USD 4.14%, which are up to 55% lower than industry averages, help improve capital efficiency.
Global market access is another differentiating factor. Interactive Brokers clients can trade across more than 160 markets worldwide, enabling diversification across regions and asset classes. This is supported by professional-grade execution, including advanced order types, smart routing and institutional-quality trading tools designed to enhance transparency and disciplined risk management.
The company is a member of the S&P 500, serves more than four million clients globally and oversees over $750bn in client assets.
Interactive Brokers founder and chairman Thomas Peterffy said, “Investment returns are not just about picking the right trades. They are influenced by the costs you pay, the prices you get, and how efficiently your capital is put to work.
“When investors pay less in fees and trade with efficient execution, those advantages add up and compound over time. All of this is more evidence that the best-informed investors choose Interactive Brokers.”
