These markets focus on predicting Chicago's weather conditions for a specific date in 2026. Outcomes depend on the exact high temperature recorded at a designated weather station, with different markets covering various temperature ranges.
All markets resolve based on the maximum temperature recorded at Chicago's CLIMDW weather station on October 29, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 68°F, 68-69°F, 70-71°F, 72-73°F, 74-75°F, or above 75°F. The Weather Company's official report is the sole determinant, even if other sources show different data. Preliminary readings may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial data before expiration, it may delay resolution until a corrected version is published or until the expiration date. If data remains unavailable by expiration, markets resolve at the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not guarantee error-free data.
