This event tracks the highest temperature recorded in Philadelphia on a specific date in the future, using official government data. The outcome depends on how hot it gets, with different ranges determining success. All markets share the same measurement source and methodology for consistency.
All markets in this event resolve based on the highest temperature recorded at Philadelphia International Airport on August 6, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). The market that matches the actual temperature range achieved will resolve to Yes, while all others resolve to No. The NWS report is the sole authority for determining outcomes, and traders should be aware that preliminary data may contain rounding or conversion nuances that could affect interpretation before the final report is published. Each market defines a specific temperature range for resolution, creating a tiered structure where only the correct range market will pay out as Yes. This approach ensures precise alignment with actual weather conditions while maintaining a clear, objective standard for evaluation.
