Polymarket International only · hourly sampling requested · may be cached for up to a few minutes. The example is the Yes token for “Xi Jinping out before 2027?”; it is live provider data, not a forecast recommendation.

Choose an outcome token or load the live example to inspect its sampled price history.

Read the historical data guide for outcome identifiers, CSV units and research limits.

What this viewer retrieves

It calls Polymarket International’s price-history endpoint with the outcome asset ID, chosen interval and 60-minute fidelity. The chart sorts samples chronologically and retains the last returned value when timestamps repeat. It does not interpolate missing records or provide historical order-book depth.

Use the exact outcome token

A market can have multiple outcome tokens. A Yes token’s prices are different from a No token’s prices; a market slug or condition ID is not the expected asset ID. Preserve the market question and outcome mapping separately before interpreting a series.

CSV fields and research notes

The CSV contains UTC timestamps and raw dollar prices, such as 0.43 for 43¢. Save the token, selected period, retrieval time and original contract rules alongside your export. The API may return an empty or incomplete history; no records are invented to fill gaps.

Price history is not an accuracy dataset

Final resolutions, contract rules, forecast horizons and sampling exclusions still need to be joined before evaluating performance. Read the accuracy methodology guide, then use the Brier calculator for independently assembled binary forecasts. This viewer does not establish a win rate or profitable strategy.
