These markets track whether Houston will reach specific temperature thresholds on September 18, 2026, based on official weather data. Each market corresponds to a different temperature range, allowing participants to assess the likelihood of various heat levels occurring on that day.
All markets resolve based on the maximum temperature recorded at the Houston (CLIHOU) location on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 89° or below, 90-91°, 92-93°, 94-95°, 96-97°, and 98° or above. The official data source is The Weather Company, and preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial data publication, the Exchange may delay resolution until a corrected value is released or until the expiration date. If no data remains available by the expiration date, markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt markets from potential revisions.
