Michael Lewis

Brad Katsuyama’s journey began in 2007 when he uncovered a troubling issue in the stock market: high-frequency trading (HFT) firms were exploiting electronic orders through a practice called front-running, causing prices to shift before trades could be completed. To combat this, Katsuyama developed "Thor," a tool that synchronized order delivery across exchanges, but he soon realized the problem was systemic, fueled by opaque practices like "dark pools" and incentives benefiting HFT firms at the expense of investors. Determined to address these injustices, Katsuyama launched an educational campaign to expose the flaws in the market and ultimately created the Investor's Exchange (IEX) in 2013, a transparent stock market designed to protect investors. Despite significant challenges, including resistance from entrenched financial institutions, Katsuyama’s efforts gained momentum, especially after Goldman Sachs, influenced by lessons from the 2008 financial crisis, placed a major order with IEX. This pivotal moment validated IEX’s mission, marking a critical step toward reforming a broken financial system.
