Shayne Coplan, founder of the prediction market platform Polymarket, has become the youngest self-made billionaire following the company's valuation reaching $9 billion. This milestone comes after overcoming significant challenges, including an FBI raid in 2024 and subsequent regulatory hurdles. In 2025, federal probes were dropped, allowing Polymarket to resume operations in the U.S. Built on the Polygon network, Polymarket facilitates event betting using stablecoins and has attracted interest from both the crypto sector and traditional finance. The platform has secured partnerships with major entities such as Intercontinental Exchange, UFC, and NHL. As the intersection of financial institutions and decentralized systems grows, Coplan's success underscores the potential of blockchain-based markets. Polymarket also adheres to Countering the Financing of Terrorism regulations, ensuring compliance with international standards.
