This event tracks the lowest temperature that will occur in San Antonio on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.
The event resolves based on the minimum temperature recorded at San Antonio's CLISAT station on September 18, 2026, as reported by The Weather Company. Six separate outcome ranges are defined: 69° or below, 70-71°, 72-73°, 74-75°, 76-77°, and 78° or above. If the recorded low falls within any of these temperature bands, the corresponding market resolves to Yes, with the final 78°+ range acting as the catch-all for any temperature above 77°. All markets share identical secondary rules regarding data verification: preliminary readings may vary due to rounding or conversion differences, and The Weather Company’s final reported value is the sole arbiter. If the Exchange identifies a material error in the initial publication before expiration, it may delay resolution until a corrected value is released or until the expiration date itself. Should no valid data exist at expiration, all markets resolve to the last fair price determined by the Exchange. The "Final" status on The Weather Company’s platform is informational only and does not override these resolution procedures.
