Description

This event assesses whether specific temperature thresholds will be met in San Antonio on October 31, 2026. Outcomes depend on the highest temperature recorded that day, with different markets covering various temperature ranges.

Kalshi

The event determines if the maximum temperature in San Antonio on October 31, 2026, falls within any of several defined ranges, with outcomes resolving based on data from The Weather Company. Each market corresponds to a specific temperature interval: below 78°F, 78–79°F, 80–81°F, 82–83°F, 84–85°F, or above 85°F. The official temperature value is exclusively sourced from The Weather Company, and users should exercise caution with preliminary data due to potential rounding or conversion discrepancies. If the Exchange identifies a material error in the initially published data, it may delay resolution until a corrected version is released or until the expiration date. Should no valid data be available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company’s platform is informational and does not guarantee data accuracy or exemption from revision.
