What is Resolved Markets?

Resolved Markets captures live orderbook snapshots from Polymarket's CLOB (Central Limit Order Book) for 100+ prediction markets across multiple categories — crypto (BTC, ETH, SOL, XRP), sports (NBA, NFL, EPL), economics (Fed/FOMC decisions), and weather (city temperatures, hurricanes, climate).

Every 250ms, the system captures full depth-of-book data including best bid/ask, spread, depth totals, and the complete bid/ask arrays — all stored in ClickHouse for columnar analytics at scale.
