IBKR Hedge Fund Clients Post Higher Returns

In 2025, Hedge fund clients posted stronger results. Their average return reached 28.91%, outperforming the benchmark by about 11 percentage points.

The company linked client performance to lower trading costs, execution quality, and access to global markets. It said these factors supported returns over time.

Thomas Peterffy, Founder and Chairman of Interactive Brokers, said returns depend on more than trade selection. He said they are influenced by “the costs you pay, the prices you get, and how efficiently your capital is put to work.”

He added that when investors “pay less in fees and trade with efficient execution,” the benefits “add up and compound over time.”

Clients Earn Interest, Margin Rates Low

During the year, clients earned interest on uninvested cash balances. The broker said rates reached up to 3.14% on eligible cash.

Interactive Brokers also pointed to its margin and financing terms. It said margin rates were as low as 4.14%, which it said were below industry averages.

The firm offers trading in stocks, options, futures, currencies, bonds, and funds through a single platform. It said it serves more than four million clients worldwide and holds over $750 billion in client assets.
