About Interactive Brokers
Interactive Brokers (IBKR) was founded in 1978 by Thomas Peterffy in the United States. Initially established as a market maker under the name T.P. & Co., the firm has since evolved into one of the largest electronic brokerage firms in the world. In 1993, it was rebranded as Interactive Brokers LLC, reflecting its focus on leveraging technology to revolutionize trading. Thomas Peterffy, considered a pioneer in electronic trading, served as CEO until stepping down in 2019, though he continues to serve as Chairman of the Board [1][7].
As of 2025, Interactive Brokers serves over 2 million institutional and retail clients across more than 200 countries and territories [1][6]. The broker is consistently ranked among the top global platforms for active traders and institutional investors due to its robust trading infrastructure, low fees, and access to over 150 markets worldwide. Headquartered in Greenwich, Connecticut, the company maintains a strong international presence with regional offices in North America, Europe, and Asia.
Global Access & Platform Ecosystem
Interactive Brokers offers access to a vast array of financial products including stocks, options, futures, forex, bonds, ETFs, mutual funds, and even cryptocurrencies through regulated partners. Its universal account model allows clients to trade across multiple asset classes from a single account. The platform supports trading on over 150 markets in 33 countries and in 27 currencies, making it a preferred choice for sophisticated global investors [1][4][5].
IBKR provides several proprietary platforms including Trader Workstation (TWS), a powerful desktop application for advanced traders; Client Portal, a web-based interface; and mobile apps for both iOS and Android. Additionally, APIs and FIX connections are available for algorithmic and institutional trading needs. For casual investors, IBKR Lite offers simplified access with no commissions on US-listed stocks and ETFs [2][5].
Trading Fees & Pricing Structure
Interactive Brokers is renowned for its low-cost pricing model. For professional traders, IBKR Pro offers tiered and fixed-rate commissions with extremely competitive rates. For example, stock trades on IBKR Pro can cost as little as $0.0005 per share (tiered) or $0.005 per share (fixed), while futures commissions start at $0.25 per contract [1][6][7].
IBKR Lite, in contrast, offers zero-commission trades on US stocks and ETFs for retail users but routes orders through market makers rather than exchanges, which may affect execution quality. The broker also offers competitive margin rates—among the lowest in the industry— starting as low as 5.83% as of 2025, depending on account balance and regulatory status [3][6].
Interactive Brokers places a strong emphasis on financial transparency and user protection. The company is publicly listed on NASDAQ under the ticker IBKR, and is regulated by several top-tier authorities including the SEC (U.S.), FINRA, FCA (UK), and other regulatory agencies globally.
Client funds are held in segregated accounts, and the broker offers SIPC protection up to $500,000 (including $250,000 for cash). It also provides excess SIPC coverage through London insurers, protecting assets beyond SIPC limits [1][5][9].
