// updated 2026-08-22
Polymarket is a prediction market, not a chain. Supanode indexes its on-chain fills and the metadata around them into a SQL-queryable warehouse - one product, the Indexer.
One product: Indexer. The history is already collected and structured - 1.82 billion fills back to November 2022. You write SQL.
What you get
- Fills: every on-chain fill leg from the CTF Exchange, with wallet, outcome token, side, token and USDC amounts, fee, maker flag, and the full Polygon transaction envelope.
- Markets: questions, outcomes, CLOB token ids, current pricing and liquidity, resolution status - 140 typed columns.
- Events: titles, slugs, categories, dates, and volume aggregated across the markets an event contains.
- Executed probability: USDC over tokens gives the traded probability directly, so the fill history is also the price history.
- Order-book depth: available separately as a CLOB capture archive - snapshots plus price-level changes, replayable to any moment. See Order-book archive.
Query it directly over ClickHouse SQL, or have us deploy custom REST endpoints for recurring queries.
