Polymarket has implemented a hybrid system that updates match scores in just 100 milliseconds, enhancing real-time market price changes based on live sports scores. This system utilizes a Central Limit Order Book (CLOB) for off-chain order matching, combined with on-chain settlement via Conditional Token Framework (CTF), which splits USDC into YES/NO shares for rapid transactions. The platform sources data directly from official league sites like the NBA and NFL through its /sports API, ensuring accurate and timely score updates. Utilizing WebSocket technology, Polymarket streams instant updates, aggregating data into a local order book without block delays. This setup allows for faster order matching compared to on-chain decentralized exchanges like Augur, which rely on slower block-based matching. Polymarket's architecture, which combines centralized speed with blockchain security, offers deep liquidity and the ability to place limit orders, providing a competitive edge in the prediction market space.
