Description

This event tracks the highest temperature reached in Boston on a specific date in the future. The outcome depends entirely on official weather data from a designated source, ensuring consistency in measurement. Participants can assess historical trends and seasonal patterns to inform their expectations.

Kalshi

The event resolves based on the maximum temperature recorded in Boston (CLIBOS) on August 16, 2026, as reported by The Weather Company. Six distinct temperature ranges define possible outcomes: 78°F or below, 79–80°F, 81–82°F, 83–84°F, 85–86°F, and 87°F or above. Each market corresponds to one of these ranges, and the official temperature value from The Weather Company is the sole determinant of the result. While other weather services may provide similar data, they are not used for resolution purposes. This structure ensures an objective, source-specific evaluation of Boston's weather conditions on the specified date.
