# Settled Prediction Markets
Monthly JSONL partitions of every prediction market that settled on Kalshi or Polymarket with meaningful volume (> $10K). Each row: venue, ticker, title, predicted price (final + t-24h), resolved outcome (0/1), resolved timestamp, category. Ideal for calibration analysis and forecasting research.
