Description

This event tracks the highest temperature reached in Boston on a specific summer day in 2026. It categorizes possible temperature outcomes into distinct ranges, each corresponding to a different market resolution. The official temperature reading comes from a designated weather data provider.

Kalshi

The event resolves based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each representing a separate market outcome: less than 84°F, 84–85°F, 86–87°F, 88–89°F, 90–91°F, and greater than 91°F. If the recorded high falls within any of these ranges, the corresponding market resolves to Yes. All markets use The Weather Company as the sole authoritative source for temperature data, ensuring consistency despite variations across other weather services. The secondary rule emphasizes that while external weather platforms may offer guidance, only The Weather Company's reported maximum temperature determines the final resolution.
