Polymarket Names Warren Jenson as First CFO to Support US Growth and Competitive Positioning
Polymarket appointed finance veteran Warren Jenson as its first CFO. Jenson brings experience from Amazon, Nielsen and LiveRamp to support US scaling under CFTC oversight. The move comes as Kalshi led August prediction market volume $40 billion to Polymarket’s share of a $48.4 billion combined total.
SCCG Take — The addition equips Polymarket with proven financial leadership to execute on $21 billion valuation and regulatory compliance. It signals a shift toward operational maturity in a market where volume leadership now favors Kalshi.
Polymarket has appointed Warren Jenson as its first chief financial officer. Jenson, 69, previously served as CFO at Amazon, Electronic Arts, Delta Air Lines and NBC. He joins as the company scales US operations under Commodity Futures Trading Commission oversight and seeks to narrow the volume gap with rival Kalshi.
Jenson will report to CEO Shayne Coplan. He most recently held the CFO post at Nielsen, which he left in January 2025. Before that, he spent more than four years as president and CFO of LiveRamp. Jenson also serves on the boards of Dropbox and Ripple.
Leadership Bench Buildout
The hire forms part of broader executive additions. This summer Polymarket named Travis VanderZanden, a former Uber executive, as chief growth officer. Founded in 2020 by Coplan, now 28, the company recently marked its sixth year.
“His experience will be critical to everything we build from here,” Coplan said. “We’re assembling the team to match the opportunity in front of us,” Coplan said.
Market Share and Regulatory Backdrop
Combined trading volume at Kalshi and Polymarket reached $48.4 billion in August, according to data from Piper Sandler. Kalshi accounted for $40 billion of that total. Polymarket is also facing newer entrants including Robinhood and DraftKings.
The company has surpassed $1 billion in annualized revenue and holds a $21 billion valuation after a $1 billion funding round. 1789 Capital, where Donald Trump Jr. is a partner, is investing about $300 million. Intercontinental Exchange disclosed a $1.6 billion stake earlier this year. Polymarket maintains a data partnership with Dow Jones and a promotional partnership with LeBron James.
The platform has drawn Senate scrutiny over its marketing practices, including allegations of social-media promotion of fake bets.
