About Polymarket

Polymarket is the world's largest prediction market where users bet on their beliefs and earn for being right. By trading on markets from politics and DeFi to conspiracy theories and culture, our users generate price-driven forecasts that provide unbiased insights into the likelihood of certain events happening. The result is an unbiased source of truth that helps people understand and better prepare for the future.

We believe the existence of markets on current events will save society from fake news and misinformation by enabling accountability on the internet — letting people put their money where their mouth is and have skin in the game rather than pushing false narratives with no consequences. Markets breed truth. Our overarching vision is to create a world where anyone can create and trade markets on anything. As the market leader, we're steadily making that dream a reality and working to redefine the way people engage with and understand the world around them, but there remains a lot left to build.
