What the contract requires
Condition. The maximum temperature recorded at Seattle (CLISEA) on September 10, 2026, is between 71 and 72 degrees Fahrenheit inclusive, as reported by The Weather Company.
Named authority. The Weather Company; Kalshi Exchange (for material error determination)
Form the evidence must take. The official and final value as reported by The Weather Company. The rules state: 'the official and final value used to determine this market is the maximum/minimum temperature as reported by the Weather Company.' Preliminary data may be subject to rounding and conversion differences. The Exchange may delay resolution if there is a material error in the initial non-preliminary publication.
Does not count.
- Preliminary data that may be subject to rounding and conversion differences from the final reported value
- Data from sources other than The Weather Company (e.g., AccuWeather, Google Weather)
Deadline. September 10, 2026, with possible extension until a non-materially-erroneous revision or the Expiration Date, whichever comes first.
- maximum temperature — the highest temperature recorded at the specified location on that date
- Seattle (CLISEA) — likely the weather station identifier for Seattle
- The Weather Company — the data provider
- preliminary — initial readings subject to rounding and conversion
- material error — determined in the sole discretion of the Exchange
This venue published no resolution text for this contract, so the condition above is inferred from the question alone.
What the sources establish
No evidence from the required authority (The Weather Company) has been provided. The sources are either forecasts for other cities, news articles unrelated to temperature, or forecasts for Seattle that are not official final data. The market is still open and the day has not yet concluded.
The evidence is not in the form this contract requires. The contract requires the official final maximum temperature as reported by The Weather Company. None of the provided sources contain any data from The Weather Company, let alone the required official final value for Seattle CLISEA on September 10, 2026.
The event may well have happened. This contract does not resolve on that alone.
The named authority has not established this. The sources below report the event; the contract resolves on what its named source says.
The official final maximum temperature for Seattle (CLISEA) on September 10, 2026, as published by The Weather Company after the day ends, showing a value between 71 and 72 °F inclusive, or a value outside that range, or a material error determination by Kalshi.
