Interactive Brokers (IBKR)

The company traces its roots to electronic market making and helped pioneer automated trading in financial markets before expanding its brokerage operations in the early 1990s. Today, clients use Interactive Brokers to trade a wide range of instruments, including stocks, options, futures, currencies, bonds, mutual funds, and exchange-traded funds. Its platforms include Trader Workstation, web and mobile tools, and application programming interfaces used by clients who need advanced order types, portfolio tools, and algorithmic trading functionality.

Interactive Brokers operates across a large network of electronic exchanges and supports trading in multiple countries and currencies. This international reach is a key part of its appeal, particularly for investors who need access to markets outside their home country. A large share of its account base is outside the United States, reflecting the company’s global positioning.

Revenue comes from commissions, net interest income, margin lending, securities lending, and other brokerage-related services. Its low margin rates and emphasis on execution quality make it especially attractive to active and professional customers, while its expanding product set has also broadened its appeal to self-directed retail investors. Interactive Brokers stands out in the brokerage industry for combining scale, automation, risk controls, and global market access in a single platform.
