Polymarket named Warren Jenson its chief financial officer on Sept. 10, placing him in charge of the prediction market's financial and capital strategy. Jenson reports directly to founder and CEO Shayne Coplan.
His responsibilities include leading the finance organization, strengthening long-range planning and developing the company's financial infrastructure. The appointment coincides with Polymarket's expansion across its U.S. exchange and international platform.
"We're assembling the team to match the opportunity in front of us," Coplan said.
Jenson previously served as CFO for Amazon, Electronic Arts, Delta Air Lines and NBC. He also held finance and operations leadership roles at Nielsen and Liveramp.
The appointment follows reports that Donald Trump Jr.'s investment firm, 1789 Capital, is investing approximately $300 million as part of a roughly $1 billion funding round that would value Polymarket at about $21 billion.
Jenson's ties to crypto predate this hire. He joined Ripple's board of directors on May 19, 2023, and chaired its audit committee. At the time, Ripple CEO Brad Garlinghouse cited Jenson's emphasis on transparency and accountability. Jenson has since identified transparency as critical for cryptocurrency companies seeking a larger role in financial services.
Jenson currently serves on the boards of Digitalocean and Dropbox.
Polymarket's domestic expansion rests on its 2025 acquisition of QCEX, a licensed derivatives exchange and clearinghouse, for $112 million. That deal gave Polymarket the regulatory infrastructure to return to the U.S. market as a designated contract market operating under Commodity Futures Trading Commission oversight.
The Polymarket platform lets traders buy and sell shares tied to real-world event outcomes. Winning contracts settle at $1, losing ones at zero.
