This event tracks whether the air temperature in Houston, Texas, will reach a certain threshold during August 2026, as measured at Houston Hobby Airport and confirmed by official weather authorities. It focuses on extreme heat conditions occurring over the specified month and location. The outcome depends solely on the official temperature recordings for that period.
If a daily maximum air temperature of at least 103°F occurs in Houston, Texas, at Houston Hobby Airport in August 2026 as confirmed by the National Weather Service, then the market resolves to Yes.
This market resolves around Sep 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, official meteorological records from Houston Hobby Airport for August 2026 will determine whether the maximum temperature reached at least 103°F. The result is binary — either the threshold is met or it isn’t — and is settled based on publicly available data without reference to internal platform mechanisms.
Several signals could shift this market before Sep 1, 2026. Early-season heatwaves, climate model updates, and government weather alerts for the Houston area often influence trader sentiment. Additionally, unexpected shifts in atmospheric patterns — such as the strength or timing of La Niña or El Niño effects — may cause rapid re-pricing. Any credible forecast indicating a high probability of extreme temperatures in August 2026 can dramatically adjust the top-outcome odds on Kalshi as traders react to new information.
