Description

This set of markets focuses on predicting Boston's weather conditions for a specific day in the future. Each market corresponds to a different temperature range, allowing participants to bet on where the actual high temperature will fall. The outcome is determined by official weather data from a designated source.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's CLIBOS station on September 6, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 66° or below, 67-68°, 69-70°, 71-72°, 73-74°, or 75° and above. The Exchange holds final discretion to address material errors in initial data publications, potentially delaying resolution until a corrected version is released or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. While other weather sources may offer guidance, only The Weather Company's official report serves as the binding determinant for all outcomes.
