Biography

A digital trading pioneer, Thomas Peterffy chairs Interactive Brokers, which markets its specialized trading platform to sophisticated investors. He founded Interactive Brokers in 1993 after originally starting in market-making, and was CEO until December 2019. In March 2017, he announced part of his market-making operation would phase out. It had been under attack by faster competitors. Peterffy arrived in America in 1965 at age 21, the penniless descendant of Hungarian aristocrats who lost nearly everything to the Soviets. He is a major landowner, with more than 560,000 acres, primarily located in his home state of Florida.
