Polymarket V1: On-Chain Prediction Market Trades from 2022 to 2026

From 2022 to 2026, this dataset captures OrderFilled events from the Polymarket prediction-market platform on the Polygon network. It contains two layers: raw on-chain trade data and a cleaned daily analysis layer with normalized probability fields. The dataset was created by TimeSeventeen and last updated in June 2026.

Use Cases

• Analyze trading volume and activity patterns based on the raw on-chain trade tape.
• Model market probability dynamics based on the cleaned, event-normalized probability fields.
• Study the behavior of market participants with relayer information removed from the daily aligned layer.
• Investigate the lifecycle of prediction markets based on the joined frozen market metadata.

Strengths

• Covers the full v1 lifecycle of the Polymarket platform from 2022 to 2026.
• Provides two structured data layers: raw events and a cleaned, analysis-ready daily layer.
• The cleaned layer includes normalized probability and direction fields for easier analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
