Description

This event tracks the highest temperature expected in Houston on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and make informed predictions about extreme heat events. The outcome depends solely on the official temperature reading from the chosen weather source.

Kalshi

The event resolves based on the maximum temperature recorded in Houston (CLIHOU) on August 18, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and methodology, ensuring consistency in evaluation. Secondary rules clarify that while other weather services may provide similar data, The Weather Company's report is the sole authority for determining the final outcome.
