Description

This event tracks the peak temperature in Philadelphia on a specific summer day in 2026, using official government data as the definitive source. It divides possible temperature outcomes into distinct ranges, each representing a different market resolution condition. The event highlights the importance of relying on authoritative meteorological reports for accuracy.

Kalshi

The event determines resolution based on the highest temperature recorded at Philadelphia International Airport on August 8, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and methodology, with the NWS report serving as the exclusive authority for temperature verification. Traders must recognize that preliminary data may contain rounding or conversion discrepancies, and final resolution depends solely on the official NWS publication. The structure creates a comprehensive temperature spectrum covering all plausible outcomes for that date, ensuring complete market coverage within defined thermal bands.
