Good morning. Polymarket makes a business out of uncertainty. Now it’s bringing some certainty to its own finances by hiring seasoned CFO Warren Jenson as its first finance chief.

Jenson, who has served as CFO of Amazon, Electronic Arts, Delta Air Lines, and NBC (then a General Electric business) as well as Nielsen, will lead Polymarket’s finance organization, set financial and capital strategy, strengthen planning, and build infrastructure for its next phase, the company announced Thursday.

Shayne Coplan, founder and CEO of Polymarket, said Jenson led finance at “some of the most consequential companies in the world, and his experience will be critical to everything we build from here.”Jenson’s hire also lands at a pivotal financial moment: Polymarket is raising about $1 billion led by the venture firm where Donald Trump Jr. is a partner, 1789 Capital, at a valuation of roughly $21 billion, which is a 40% jump from the $15 billion mark it garnered just months ago.

Jenson’s most recent CFO role was at Nielsen, where he also served as president and led the company’s modernization and analytics business. Before that, he was president at LiveRamp, where he led finance and international efforts.
