Jenson is a veteran executive with a long track record in finance leadership. He previously served as CFO at Amazon, NBC, Delta Air Lines and Electronic Arts during the 1990s and early 2000s.
More recently, Jenson was president and CFO at Nielsen, which he left in January 2025. Before that, he spent over four years as president and CFO of data platform LiveRamp. He currently sits on the boards of Ripple, Dropbox and DigitalOcean.
Jenson will report directly to Polymarket founder and CEO Shayne Coplan. He will oversee finance, capital strategy and long-term planning for the company.
“Warren has led finance at some of the most consequential companies in the world, and his experience will be critical to everything we build from here,” Coplan said.
Building Out the U.S. Platform
The hire comes at a key moment for Polymarket. The company is working to grow its regulated U.S. exchange after coming under oversight from the Commodity Futures Trading Commission.
Polymarket had been largely blocked from the U.S. market since a 2022 CFTC settlement required it to shut out American users. It has been working to change that.
This summer, the company also brought in Travis VanderZanden, founder of a scooter-sharing company, as its chief growth officer. Coplan said he is building a leadership team to handle the next phase of the company’s growth.
“We’re assembling the team to match the opportunity in front of us,” Coplan said.
Polymarket lets users trade on the outcomes of future events using USDC. Trades are recorded and settled on the Polygon blockchain.
Funding and Competition
Polymarket is currently valued at around $21 billion. That valuation follows a recent $1 billion funding round.
1789 Capital, a venture capital firm where Donald Trump Jr. is a partner, is putting in around $300 million. Intercontinental Exchange also holds a disclosed stake of $1.6 billion.
The company has a data partnership with Dow Jones, publisher of The Wall Street Journal.
Polymarket faces growing competition in the prediction markets space. Rivals include Kalshi, as well as newer entrants Robinhood and DraftKings.
The platform broke into the mainstream during the 2024 U.S. presidential election. Since then, it has expanded into sports markets.
The company has also faced some controversy. U.S. senators have called for a federal investigation into its marketing practices, including social media promotion of what critics described as fake bets.
Jenson said he sees the platform as a major opportunity. “Polymarket created a massive new global market category,” he said. “I’m joining Shayne and the leadership team to put the capital strategy and operating discipline in place to move quickly at scale.”
