What the contract requires
Condition. The maximum temperature recorded at Boston (CLIBOS) on October 1, 2026, is between 79 and 80 degrees Fahrenheit inclusive, according to The Weather Company's official final data.
Named authority. The Weather Company (owner of weather.com)
Form the evidence must take. The official and final maximum/minimum temperature as reported by The Weather Company, specifically the non-preliminary publication that is considered final. The rules mention that a status of 'Final' on weather.com/kalshi is provided for convenience but does not guarantee error-freeness. The data must be from The Weather Company, not other sources like AccuWeather or Google Weather.
Does not count.
- Preliminary Weather Company data that has not been finalized.
- Data from any source other than The Weather Company, such as AccuWeather, Google Weather, or other private/third-party services.
- Data for a different date or location (e.g., not CLIBOS or not October 1, 2026).
- The temperature value rounded or converted differently from The Weather Company's official final value.
Deadline. Not explicitly specified beyond the event date (October 1, 2026). The rules refer to 'Expiration Date' without defining it, and allow delays if material errors are found in the initial non-preliminary publication, up to the Expiration Date or a corrected revision, whichever comes first. If no data is available by then, the market resolves to the last fair price.
