David Silber, Head of Institutional Equity Derivatives, Citadel Securities

It was a pleasure to welcome David Silber, Head of Institutional Equity Derivatives at Citadel Securities, to the Alpha Exchange to discuss the evolution of listed options markets, institutional liquidity, and the technology reshaping modern derivatives trading. We begin with Dave’s early career on the floor of the Chicago Board Options Exchange during the transition to multi-listed options, where market making, open outcry, and physical proximity to order flow defined liquidity provision. He reflects on the evolution of the options market from paper tickets and fractional pricing to today's electronic ecosystem, highlighting how advances in technology have fundamentally changed both price discovery and risk management. We then turn to the creation of Citadel Securities’ institutional derivatives business. Dave explains how his experience across multiple firms led him to identify opportunities to reduce friction in institutional options execution by combining technology, quantitative research, and broad access to liquidity. He describes how automation, electronic execution, and competitive pricing have transformed the institutional trading experience while expanding access to listed options. The discussion also examines recent growth in listed options markets, including increasing contract volumes, shorter-dated expirations, and the expanding use of listed options by institutional investors for hedging, leverage, and portfolio management. Dave shares his perspective on liquidity provision, risk management, and the importance of maintaining resilient markets during periods of elevated activity. We conclude with a discussion on recruiting talent, developing strategy and data products for clients, and aligning sales, trading, and technology teams around creating a more efficient experience for institutional investors. I hope you enjoy this episode of the Alpha Exchange, my conversation with David Silber.
