Bain Capital VenturesTTDF VenturesIEX Exchange is a U.S. stock exchange founded in 2012 by Brad Katsuyama and Ronan Ryan to counter high-frequency trading practices, opening for trading in October 2013 and becoming a registered national securities exchange in September 2016. Its signature feature is a 38-mile coil of fiber-optic cable that creates a 350-microsecond speed bump in front of its matching engine in Weehawken, New Jersey.
The exchange won SEC approval to list companies in October 2017 and listed its first company, Interactive Brokers, in October 2018, before leaving the listing business in September 2019. IEX traded $40 billion daily as of the first half of 2026 and won the 2025 Global Markets Choice Award for Most Innovative Exchange.
