ALT Line chart titled 'Polymarket calibration, by price decile.' Each market is plotted once, at the price of the outcome Polymarket lists first (Yes, on Yes/No markets). X axis: that outcome's stated price as implied probability. Y axis: share that resolved yes, meaning the first-listed outcome happened. Two lines, 24 hours before resolution (blue) and 30 days before resolution (orange), against a dashed perfect-calibration diagonal. The 24-hour line tracks the diagonal below 80 cents, and its top two bins resolve under their stated price. The 30-day line sits below the diagonal in every bin from 10 cents up. Covers all resolved markets October 2025 through September 2026, short-duration Up/Down price markets excluded by policy.
