Shayne Coplan, Founder of Polymarket

At just 26 years old, Shayne Coplan has transformed Polymarket into a cultural powerhouse that’s redefining how the world predicts and engages with events both big and small.

From accurately forecasting U.S. election results to shaping conversations across politics, sports, and global affairs, Polymarket has become the go-to platform for real-time predictions and a mirror of public sentiment.

It’s not just the world’s largest prediction market—it’s a cultural phenomenon, shaping how we understand the future.

How did Shayne take an ambitious idea and turn it into one of the most impactful tools for prediction?
