What happened
Polymarket appointed Warren Jenson as chief financial officer, announcing the hire in a PR Newswire release dated September 10, 2026. Bloomberg's headline the same day described him as the company's first CFO. The release said Jenson would lead the finance organization and set financial and capital strategy, and would also oversee long-range planning and building the company's infrastructure. He reports to founder and chief executive Shayne Coplan.
The release said Jenson was previously CFO of Amazon, Electronic Arts, Delta Air Lines and NBC. He was also president and CFO at Nielsen and president at LiveRamp, where he led finance and ran international efforts. He serves on the boards of DigitalOcean, Dropbox and Ripple. The release said the appointment came as Polymarket scaled its CFTC-regulated U.S. exchange, expanded its global platform and added senior leaders. Bloomberg's headline tied the hire to a push to regain ground on Kalshi. The release gave no start date, compensation or equity terms.

Why it matters
Bloomberg's headline called Jenson Polymarket's first CFO. The new role owns financial and capital strategy, a function the company had not filled at that level before.
Jenson's earlier CFO roles at Amazon, Electronic Arts, Delta Air Lines and NBC, per the release, show the scale of finance operation he has run before.
The company tied the hire to scaling its CFTC-regulated U.S. exchange, so the finance function is being built alongside regulatory exposure.
