Current coverage
This page currently includes 11 source-reviewed direct matches. The count reflects products that directly complete this task, not a ranking, endorsement or investment-performance score.
Task match
Choose Polymarket historical replay products by archive start date, event and quote granularity, recorded versus reconstructed order books, symbol mapping, export format and survivorship handling. Backtests should model fees, latency and realistic fill constraints.
Direct answer and selection criteria
This page currently includes 11 source-reviewed direct matches. The count reflects products that directly complete this task, not a ranking, endorsement or investment-performance score.
Separate recorded from reconstructed order books. Confirm archive start, sampling gaps and market mapping, then model latency, fees and queue position before treating a replay as an executable backtest.
Check official sources, the latest editorial review date, access requirements and key limitations before choosing. “Unknown” means the fact was not established in public official material; it does not mean no. The latest content update represented here is dated Oct 9, 2026. Methodology.
Evidence-based comparison
For backtests and market replay, the collection method matters as much as the file format.
These can preserve timestamped bid and ask states, subject to the recorder's uptime, depth and capture interval.
These may be useful for research but can omit cancelled orders, queue position or states between sampled observations.
Historical visibility does not establish executable fills. Model latency, fees, slippage, queue priority and data gaps separately.
Product profiles link the first-party sources behind applicable facts. Unknown means the available official material did not establish the fact. Review the methodology.

Practical selection guide
Choose the observation you need before comparing providers: a price series, executed trades and a recorded order book answer different questions.
Record the market and outcome identifiers, required dates and timezone. Check the earliest available observation and resolved-market coverage rather than assuming an archive covers every market.
For a price series, check timestamps and sampling resolution. For trades, check the event fields. For an order book, check bid/ask depth, capture intervals and gaps. A price-history series does not establish historical order-book depth.
Open the linked product profile and source to verify export format, access conditions and documented limitations. Keep the query settings and extraction date with your sample; unavailable coverage remains unknown.
A replay can inspect past observations; it cannot guarantee that an order would have filled. State assumptions for latency, fees, slippage and queue priority before interpreting a backtest.
These are existing catalog reviews, not new hands-on tests. Check each profile’s dated evidence before relying on a capability or price. Unknown remains unknown.
