What is Polymarket?

Polymarket is a decentralized prediction market where you trade on real-world outcomes—elections, sports (NFL, NBA, soccer, tennis, etc.), and more. Prices reflect market sentiment. This polymarket-sports-trading-bot connects to Polymarket’s APIs (Gamma + CLOB) to automate polymarket-sports-betting on selected sports markets.
