Polymarket order-book depth snapshots (sample)
Event-driven L2 order-book history for short-dated Polymarket crypto markets.
Prediction-market venues publish a live order book and archive none of it. Once a
five-minute market resolves, its depth history is gone and cannot be backfilled by

Capture is event-driven — a snapshot is written on every book and price_change
message rather than on a fixed sampling interval.… See the full description on the dataset page: https://huggingface.co/datasets/V-Corp/polymarket-orderbook-depth-sample.high_frequency_crypto_orderbook
