Calibration Scorecards (Hugging Face)

Monthly Brier + log-loss breakdowns for Kalshi + Polymarket

Monthly rollups of calibration metrics computed off settled-markets. Each month provides:

  • Mean Brier + mean log-loss (overall)
  • Per-venue (Kalshi vs Polymarket) breakdowns
  • Per-category (macro, geo, crypto, event, policy, ...) breakdowns
  • 10-bucket calibration histogram (actual resolution rate vs predicted probability)

Published with a 14-day delay after month-end to capture late resolutions. Good benchmark for any probabilistic forecaster.
