Polymarket sports historical data
Polymarket runs per game markets across the major leagues: moneylines, totals, spreads, and in game props for MLB, NBA, NFL, NHL, ATP and WTA tennis, UFC, and soccer competitions. Odds move continuously from listing through the final whistle, and the order book records how the market digested every scoring play.
Marketlens captures the full order book for every game, so line movement survives at millisecond resolution: opening prices, pre game drift, in game repricing. Polymarket's own API serves only the live book; this archive is the historical record.

How much do these markets trade?

Can I backtest strategies on sports markets?

Execution mode replays the order books tick by tick and fills simulated orders against real depth with queue priority, latency, and fee modelling; Alpha mode replays one bar per market for slower signals over long windows.
Other categories: crypto, weather, equities, or the full catalog.
