A real time prediction market platform inspired by Polymarket and Kalshi, built for a University of Chicago Physics PhD department event. Users trade on outcome probabilities across department-specific questions using currency, with real-time market pricing, automated resolution, and a live leaderboard to drive engagement in forecasting event outcomes.
The platform allows 200–300+ simultaneous participants to trade virtual currency on department specific outcomes, with prices updating dynamically to represent the group’s changing predictions. Built with JavaScript and Firebase Realtime Database, it synchronizes trades, balances, portfolios, messages, and leaderboard rankings across connected devices. A custom pool based market model powers the probability pricing and proportional payouts, while an administrative dashboard handles market creation, user management, outcome resolution, and automatic settlement.
