Frontrunner is a decentralized sports prediction market where users can buy shares of sports propositions and trade them like they would options, contracts, or stocks. 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 fully transparent markets and liquid positions which fundamentally change the way that people invest in their sports knowledge and beliefs.
