Description

This event tracks the highest temperature recorded in Houston on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on how warm it gets that day, with different markets covering various temperature ranges.

Kalshi

All markets resolve based solely on the maximum temperature recorded at the Houston (CLIHOU) location on September 17, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 88°F, 88-89°F, 90-91°F, 92-93°F, 94-95°F, or above 95°F. The Exchange reserves the right to delay resolution if it identifies a material error in the initial data publication, extending the evaluation period until a corrected version is released or the expiration date passes. If data remains unavailable by the expiration date, all markets will resolve at the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion factors, and users should exercise caution when interpreting early data. The 'Final' status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential resolution adjustments.
