Every crypto prediction market on Polymarket, captured tick-by-tick: the BTC, ETH, SOL, XRP, DOGE, BNB and HYPE up-or-down ladders at 5m and 15m, the hourly multi-strike books, and the longer-dated price targets.
These are the fastest-repricing books on the venue. A 5-minute up-or-down market reprices continuously against spot, so the order book carries the reaction to every move in the underlying — which is why this vertical is usually bought for latency and microstructure work rather than for outcome studies.
A free account claims 5 market·days from July 2026, or buy a single market·day à la carte from $2.
Ranked by how many distinct questions each one has run. Every title links to its own coverage page.
The same three layers as everywhere else in the archive: L1 best bid/ask written on every change, the 25-level L2 ladder on every book update, and the complete trade tape with price, size and aggressor side. All of it came off Polymarket's own websocket feed as it happened, recorded by dual-region sequence-audited collectors — not reconstructed from a public REST endpoint afterwards, which is the difference that matters once you care about resting size and spread regimes.
Bundles arrive as parquet with a CSV twin and a reference dictionary mapping every id back to the real question. The full schema is documented here. For the crypto price feeds themselves — exchange spot, the Chainlink oracle and the TWAPs these markets settle against — see tick-by-tick crypto data.
