How to Export Polymarket Prediction Market Data (Odds, Volume, Trades)
Polymarket lets you browse prediction markets one at a time, but there is no bulk export for tracking odds movement, volume, or trading activity across markets. This tool pulls markets, grouped events, or individual trades as structured data — question, current odds, volume, liquidity, and price history fields.
In short: Manually checking odds and volume across many prediction markets doesn't scale, and prices move constantly as new information comes in. This tool automates it — you get structured, ready-to-use data instead of copying it by hand.
What the data shows: In this sample of 10 active markets, topics range from F1 race outcomes to Ethereum price thresholds to corporate IPO timing — each with a live, crowd-sourced probability from 0% to 99% that updates as new information comes in, the kind of real-time signal that requires checking dozens of individual pages to gather by hand.
