Price history
Polymarket price history for 5-minute crypto markets
Full price history for every Polymarket 5-minute Up or Down window: every change to the best bid and ask on both outcomes, every trade, and the official opening and closing prices each window settled on.
Two kinds of “price”
Market prices are what the Up and Down shares traded at, between 0 and 1 dollar. Our book and trade files give these tick by tick, with millisecond timestamps.
Settlement prices are the crypto prices each window resolved on: Polymarket's opening and closing 60-second Chainlink TWAPs. They are in our window files as open_twap60 and close_twap60, alongside the result.
Why not just use the API?
Polymarket's public API gives a price series for a market, sampled over time, and the order book as it is right now. It does not give you the past order book, which is what you need to know what you could actually have bought and at what size. Our files are recorded live from the market feed, so the history includes the book.
