Description

This event tracks the highest temperature recorded in Louisville on a specific date in the future, using data from a designated weather provider. The outcome depends on where the temperature falls within predefined ranges, reflecting possible weather conditions for that day.

Kalshi

The event determines the outcome based on the maximum temperature recorded in Louisville on September 3, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that resolves to Yes if the recorded temperature falls within that range. All markets share common secondary rules emphasizing that The Weather Company’s data is the official source, despite potential discrepancies with other weather services. Preliminary data may be subject to rounding or conversion differences, and participants should exercise caution when interpreting early readings. The exchange retains the discretion to address material errors in the initial data publication by extending the expiration period until a corrected version is released or the original expiration date passes, whichever comes first. If 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 only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
