Interactive Brokers (IB) is a U.S.-based online discount brokerage firm. It is headquartered in Greenwich, Connecticut and has a number of offices around the world. The IB Group consists of subsidiaries operating on a number of stock, option, futures, and bond exchanges worldwide and also provides trading in ETFs and CFDs.
IB is regulated by the U.S. Securities and Exchange Commission and the regulatory policies of the exchanges on which it trades. IB posts its Electronic Brokerage monthly performance metrics on its website.
In 2009 Barron's Magazine said that Interactive Brokers maintained a position as "the least expensive trading venue for investors." IB has held the ranking as the lowest cost broker for five straight years.
The company started in 1977 when Thomas Peterffy bought a seat on the American Stock Exchange as an individual market maker. The following year he formed T.P. & Co. to expand trading activities to several members under badge number 549. The firm was the first to use computer-generated fair value sheets printed daily.
Timber Hill was formed in 1982, and in 1983 were the first to use handheld computers for trading, allowing them to track positions and rapidly re-price options on one stock, unlike others who used fair value pricing sheets updated once or twice a day.
In 1984 Timber Hill began coding a computerized stock index futures and options trading system, and in February 1985 Timber Hill's system and network was brought online, allowing computerized trading; Timber Hill could now centrally price and manage risk on a portfolio of equity derivatives traded in multiple locations around the country.
By 1987 Timber Hill had become self-clearing in equities and joined the National Securities Clearing Corp. and the Depository Trust Company. They also became members of The Options Clearing Corporation, the New York Futures Exchange, the Pacific Stock Exchange and the options division of the NYSE. The firm traded on the PSE, the CME, the CBOT and the CBOE.
In 1990 Timber Hill Deutschland GmbH was incorporated in Germany, and shortly thereafter began trading equity derivatives at the Deutsche Terminborse (DTB), now Eurex, for the first time applying its trading system on a fully automated exchange.
In 1993 Interactive Brokers Inc. was incorporated as a US broker-dealer, making Timber Hill's intercontinental electronic network and trade execution services available to customers. In 1995 IB developed a customer trader workstation which provided professional customers access to exchanges around the world, and IB executed its first trades for public customers.
In 2000 IB introduced a "smart routing" linkage for multiple-listed equity options, and began to clear online trades for customers trading stocks and equity derivatives through the IB system.
In 2001 the corporate name of The Timber Hill Group LLC was changed to Interactive Brokers Group LLC.
On May 3, 2007 the company issued 40,000,000 shares or approximately 10% of the capital of Interactive Brokers Group LLC in a public offering, at a price of US$30.01 per share under the NASDAQ ticker symbol IBKR.
In 2011 Interactive Brokers became the largest online broker in the US as measured by Daily Average Revenue Trades.
The company is headquartered in Greenwich, Connecticut in the United States and has offices in Budapest, Chicago, Hong Kong, London, Montreal, Mumbai, Shanghai, Saint Petersburg, Sydney, Tallinn, Tokyo, and Zug.

In 2014 Interactive Brokers, according to their Web site, introduced "exposure fees", overriding margin requirements, for accounts which carry short options positions or other positions the firm deems high-risk, which other firms do not charge. A fluctuating daily fee is charged in addition to the usual commissions and to the initial and margin maintenance fee for these positions. IB say that they calculate this fee on their own discretion and using their own algorithms, subject to change without notice.  This sparked objection in many forums regarding the impact of these non-standard additional fees.  Analysis of the calculations shown on the IB Web site indicated that many charges were higher than traditional brokers; e.g., borrow rates based on security prices were rounded up to the nearest dollar, as opposed to industry standard of just 102% or price, etc.[clarification needed]
