Description

This event tracks the highest temperature reached in San Antonio on a specific date in the future, using data from a designated weather authority. Participants assess the likelihood of different temperature ranges based on historical trends and climate forecasts. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event resolves based on the maximum temperature recorded in San Antonio (CLISAT) on August 20, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes. All markets are mutually exclusive and collectively exhaustive, ensuring one and only one will resolve as Yes depending on where the actual temperature falls. The Weather Company’s data is the sole authority for determining the official temperature, and all participants must accept this source as final regardless of discrepancies with other weather services.
