Interactive Brokers (IBKR) was founded by Thomas Peterffy in 1978. Initially, the firm began its journey as a market maker, a crucial player that provides liquidity in financial markets. Peterffy was a pioneer in the early adoption of computerized trading, utilizing automated systems at a time when most trading was manually executed. By the mid-1980s, IBKR transitioned from trading on the floor to the screen, being one of the first to use computer-generated fair value sheets. Over the years, the firm shifted its focus from market-making to brokerage, capitalizing on its cutting-edge technology to offer advanced trading platforms. This transition allowed IBKR to serve a broader clientele, from individual traders to large institutions, giving them access to global markets at competitive rates.
