Overview

ChainStream GraphQL provides three Cubes for prediction market data, primarily available on Polygon. These Cubes cover the full lifecycle of prediction markets — from creation and trading to settlement.
Prediction Market Cubes are available in the EVM Chain Group. They are primarily used with network: polygon.

​
PredictionTrades

​
Recent Prediction Market Trades

  EVM(network: polygon) {
    PredictionTrades(
      limit: {count: 20}
      orderBy: Block_Time_DESC

      Block { Time }
      Transaction { Hash }
      Trade {
