Frontrunner is a decentralized sports prediction market where users can buy shares of sports propositions and trade them like they would stocks or options. Unlike traditional sportsbooks where users place a bet and wait, Frontrunner gives users full control over their portfolios, allowing them to dynamically buy and sell positions as the odds change. By leveraging the power of free markets and the blockchain, we create transparent markets and liquid positions to reduce counterparty risk, create new types of sports-related markets, and fundamentally change the way in which people invest in their sports knowledge and beliefs.
