Shayne Coplan, founder and CEO of Polymarket, has become the youngest self-made billionaire following a $2 billion investment from the Intercontinental Exchange at an $8 billion valuation. The platform, which allows users to wager on real-world outcomes using cryptocurrency, gained significant traction during the 2024 U.S. presidential election, despite facing regulatory challenges and penalties in the past. With a recent acquisition of a licensed exchange, Polymarket is now positioned as a legitimate player in the gambling and financial forecasting industries.
