Description

This event tracks the lowest temperature recorded in Boston on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and make informed predictions about temperature patterns. The outcome depends solely on the official temperature report from The Weather Company.

Kalshi

The event determines the resolution based on the minimum temperature recorded at Boston’s CLIBOS station on August 20, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the recorded low falls within a particular range, that market resolves to Yes; all others resolve to No. While other weather sources may offer similar data for reference, The Weather Company’s report is the exclusive, binding authority for all determinations. This structure ensures clarity and consistency in evaluating the event’s outcome.
