Interactive Brokers Group Inc shares rose 2.2% on Friday after the global electronic broker announced that its clients outperformed the S&P 500 Index in 2025.
The company reported that individual clients generated an average return of 19.20% for the year, exceeding the S&P 500’s 17.9% gain. Performance was even stronger among hedge fund clients, who delivered an average return of 28.91%, beating the benchmark by roughly 11 percentage points.
Interactive Brokers said this outperformance was driven by a combination of structural advantages designed to improve results across the entire investment process. These include access to more than 160 global markets, lower trading and financing costs, and highly efficient trade execution that helps investors keep a larger share of their returns.
“Investment returns are not just about picking the right trades,” said Thomas Peterffy, founder and chairman of Interactive Brokers. “They are shaped by the costs you pay, the prices you receive, and how effectively your capital is deployed.”
The firm also pointed to several platform features that supported client performance in 2025. These included interest rates of up to 3.14% on uninvested cash balances and margin rates as low as 4.14%, which are up to 55% below industry averages.
Interactive Brokers, which is listed on Nasdaq and is a member of the S&P 500, now serves more than 4 million clients worldwide and oversees over $750 billion in client assets.
