What the archive says about markets like this
This market is one of 1,914 resolved binary contracts in the PredictWire Calibration Archive. A Polymarket contract with lifetime volume of $400.4M sits in the top tier of archive volume — very liquid markets have a volume-weighted Brier of 0.0665 across the archive, compared to 0.0865 for the full set. Liquidity matters for calibration.
The Wire Score framework uses every (price, outcome) pair in the archive to calibrate raw prices into probabilities and to assign a letter grade based on confidence-band width. v2 fits a separate calibration curve per category (politics, sports, crypto, geopolitics, other) and falls back to a global curve when a category is too thin. Across all 194,111 archive snapshots, Wire Score v2 improves Brier by +4.86% over raw prices (and +2.85% over v1) while remaining monotone across grades.
