This set of markets will determine the lowest temperature recorded in Houston on a specific date in the future. The outcome depends solely on official weather data from a designated source, making it a straightforward test of meteorological conditions for that day.
All markets resolve based on the minimum temperature recorded at Houston (CLIHOU) on September 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 71°F, 71-72°F, 73-74°F, 75-76°F, 77-78°F, or above 78°F. The official data from The Weather Company is the sole determinant, even if other sources show different values. Preliminary data may be subject to rounding or conversion differences, so participants should exercise caution. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential revisions.
