Polymarket has appointed Warren Jenson as its first chief financial officer as the prediction-markets platform expands its regulated U.S. exchange.

The company announced the appointment on Thursday. Jenson will report directly to Polymarket founder and CEO Shayne Coplan and oversee finance, capital strategy, and long-term planning. The newly created role places one executive in charge of the company's finances as it scales its U.S. operations under federal oversight.

Jenson has held senior finance roles at Amazon, NBC, Delta Air Lines, and Electronic Arts during the 1990s and early 2000s. More recently, he served as president and CFO of Nielsen, leaving the company in January 2025. Before Nielsen, he spent more than four years as president and CFO of data platform LiveRamp. He currently serves on the boards of Ripple, Dropbox, and DigitalOcean.

“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.

Expanding the U.S. Platform

Jenson’s appointment comes as Polymarket works to expand its regulated U.S. exchange under the oversight of the Commodity Futures Trading Commission, or CFTC. The agency regulates U.S. derivatives markets, including the event contracts at the heart of prediction markets.

Polymarket had been largely blocked from the U.S. market after a 2022 CFTC settlement required it to exclude American users. The company has since been working to reenter and develop its U.S. operations.

This summer, Polymarket also hired Travis VanderZanden, the founder of a scooter-sharing company, as chief growth officer. Coplan said the company is building a leadership team for its next phase of growth.

“We’re assembling the team to match the opportunity in front of us,” Coplan said.

Polymarket allows users to trade on the outcomes of future events using USDC, a U.S. dollar-pegged stablecoin. Trades are recorded and settled on the Polygon blockchain.

Valuation, Funding, and Competition

Polymarket is valued at around $21 billion following a recent $1 billion funding round. 1789 Capital, a venture capital firm whose partners include Donald Trump Jr., is investing around $300 million in the company. Intercontinental Exchange also holds a disclosed stake valued at $1.6 billion.

Polymarket has a data partnership with Dow Jones, the publisher of The Wall Street Journal. The combination of an exchange-operator stake and a major media data partnership reflects prediction markets’ growing overlap with mainstream finance.

The company faces competition from established prediction-market platform Kalshi and newer entrants Robinhood and DraftKings. Polymarket gained mainstream attention during the 2024 U.S. presidential election and has since expanded into sports markets.

The platform has also faced scrutiny. U.S. senators have called for a federal investigation into its marketing practices, including the promotion on social media of what critics described as fake bets. How that push develops, alongside the pace of the U.S. exchange buildout, is a key area to watch as the company scales.

Jenson described Polymarket 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.”
