This event tracks the highest temperature that will be recorded in San Antonio on a specific future date. The outcome depends solely on official weather data from a designated source, making it a straightforward test of meteorological prediction accuracy.
The event determines whether the maximum temperature in San Antonio on October 18, 2026, falls within specific ranges as reported by The Weather Company. Each market corresponds to a distinct temperature range, with one market resolving if the temperature is 70°F or below, another for 71-72°F, and so on, up to a final market for temperatures above 78°F. All markets use The Weather Company as the exclusive source for temperature data, with provisions for handling preliminary data, potential errors, and unresolved data scenarios. If a material error is identified in the initial data publication, the expiration may be delayed until a corrected value is released or until the expiration date, whichever comes first. In cases where data remains unavailable by the expiration date, all markets resolve to the last fair price determined by the exchange. The 'Final' status on The Weather Company's platform is informational and does not exempt the data from potential revisions or error handling under these rules.
