Description

The event focuses on the lowest temperature in San Antonio on August 18, 2026, using The Weather Company’s data as the official record. Outcomes are determined by where the minimum temperature falls within predefined ranges.

Kalshi

The market resolves based on the minimum temperature recorded at San Antonio (CLISAT) on August 18, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature is 70°F or below, the first market resolves to Yes. If it is between 71°F and 72°F, the second market resolves to Yes, and this pattern continues for subsequent ranges up to 77°F to 78°F. For temperatures of 79°F or above, the final market resolves to Yes. The Weather Company’s data is the sole authority for determining the outcome, and all participants must rely on this source for accuracy.
