Thomas Peterffy is the founder, chairman and chief executive officer of Interactive Brokers Group, Inc., the U.S.-based broker-dealer and proprietary trading business.[1][2]

He announced in January 2019 that he will step down as CEO in Q3 2019, concurrent with his 79th birthday, after running Interactive Brokers for 42 years. He appointed Milan Galik as CEO but will remain chairman.[3]


Peterffy emigrated from Hungary to the United States in 1965.[4] After working for 10 years as computer programmer, he became a member and options trader at the American Stock Exchange.

Peterffy developed hand-held computers as an aide to floor trading in the early 1980s, ahead of much of the rest of the industry. He established Timber Hill as a proprietary trading firm and used his technological edge to make it into a major market making firm.

When high-speed trading came along it squeezed the profit out of Timber Hill's computer-driven marketmaking operation, so Peterffy looked to develope his own discount brokerage.[5] He began developing a communications network in the 1980s for routing orders to exchanges and stock markets around the world, which became the foundation for Interactive Brokers Group, Inc. His smart order routing systems created a model for customer execution.[6][7]


Peterffy received the Joseph P. Sullivan Award at the 24th Annual Options Industry Conference in May 2006, and in 2007 he was inducted into the FIA Futures Hall of Fame.

In November of 2007, Peterffy received the American Hungarian Foundation George Washington Award.[8]
