Resolved Markets API
Real-time and historical orderbook data from Polymarket prediction markets across crypto, sports, economics, weather, social, and equities — captured at up to ~10Hz with millisecond precision.
What is Resolved Markets?
Resolved Markets captures live orderbook snapshots from Polymarket's CLOB (Central Limit Order Book) for 100+ prediction markets across six categories — crypto (BTC, ETH, SOL, XRP), sports (NBA, NFL, EPL), economics (Fed/FOMC, Nonfarm Payroll), weather (city temperatures, hurricanes, climate), social (Elon tweets), and equities (S&P 500 Up/Down).
Capture is event-driven and throttled per-category: crypto books update every 100ms (~10Hz), S&P 500 every 1s, sports every 500ms, economics every 2s, daily weather every 2s, and social every 3s. Each snapshot includes full depth-of-book (bids/asks arrays), best bid/ask, mid price, spread, depth totals, sequence numbers, and the crypto spot price at capture — all stored in ClickHouse for columnar analytics at scale.
