Prediction Markets Daily Markets
Every Polymarket market since November 2022, point in time: its question, rules, outcomes, event and tags, the date it was created and, from the moment it was resolved and not before, its outcome. The companion of PredictionMarkets-Hourly-Price and PredictionMarkets-Daily-Price, whose symbol values are listed here per market.
Point in Time
Each market has one row dated created_at, with resolved false and every outcome field null, and, once resolved, a second row dated resolved_at carrying payouts and winning_outcome. Take, for each market, the last row with date <= t: that is what was known at t. A market is absent before its creation.
resolved_at is the block time of the oracle's on-chain settlement (resolution_source = onchain). For markets resolved after 2026-10-26 it is Polymarket's closing time plus two hours (gamma): that closing time preceded the on-chain settlement on 11 % of the markets sampled, by up to 37 minutes, so the margin makes the date late rather than early.
The descriptive fields (question, rules, end date, tags) are Polymarket's current text as of metadata_asof; Polymarket can edit an end date after creation.
Not Included
The 5- and 15-minute "Up or Down" crypto markets (the majority of markets created in 2026) are left out. Hourly and daily "Up or Down" markets are kept.
