Polymarket has appointed veteran finance executive Warren Jenson, former CFO of Amazon and Delta Air Lines, as its first chief financial officer. The hire comes as the prediction market platform seeks to scale its CFTC-regulated U.S. exchange and reclaim market share from rival Kalshi, which recorded $40 billion in trading volume in August 2026 compared to Polymarket's smaller share. Jenson will oversee capital strategy and long-term planning under CEO Shayne Coplan.
