Polymarket appoints former Amazon CFO Warren Jenson

Polymarket has appointed veteran finance executive Warren Jenson as its new Chief Financial Officer. Jenson, who previously held CFO roles at Amazon, Electronic Arts, Delta Air Lines, and NBC, will report to Founder and CEO Shayne Coplan. His responsibilities will include overseeing financial operations, capital planning, long-term business strategy, and the development of financial infrastructure to support the company’s growth.

The appointment comes as Polymarket seeks to expand its U.S. presence and compete more effectively with rival prediction market Kalshi. While Polymarket recently surpassed $1 billion in annualized revenue, it faces significant competition in trading volume. Data from Piper Sandler indicates that in August, combined volumes for Kalshi and Polymarket reached $48.4 billion, with Kalshi accounting for approximately $40 billion of that total.

In addition to Jenson, Polymarket has recruited former Uber executive Travis VanderZanden as Chief Growth Officer to strengthen its leadership team during a period of rapid industry expansion.
