# Prediction Markets

> Query examples for PredictionTrades, PredictionManagements, and PredictionSettlements Cubes

## 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.

<Note>
  Prediction Market Cubes are available in the **EVM** Chain Group. They are primarily used with `network: polygon`.
