The event tracks whether Denver experiences at least two consecutive days with average temperatures above 90°F during the week of August 24-30, 2026. It uses official weather data to determine daily averages from hourly readings.
Multiple markets assess consecutive days of Denver's average temperature exceeding 90°F from August 24–30, 2026. Each market requires a specific minimum streak length (2–6+ days) of daily averages strictly above 90°F, calculated as the mean of hourly temperatures reported by The Weather Company for KDEN from 12:00 AM to 11:59 PM local time, rounded to the nearest degree. Only days within the specified week count, and a day with fewer than 18 hourly values or an average of exactly 90°F breaks the streak. Data is taken as published at expiration; later revisions are ignored.
This market resolves around Sep 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Official meteorological data from recognized sources will be used to determine whether the average temperature in Denver reached above 90°F for two or more consecutive days during the specified week. Until then, traders can continue to buy or sell contracts based on evolving expectations.
Key signals include medium- to long-range weather outlooks from national meteorological services, sudden shifts in atmospheric patterns like heat dome formations, and updates from regional climate models. Any announcement indicating a higher probability of prolonged heat in the Denver area could push this market toward higher prices, while cooler-than-expected forecasts may drive prices down. Traders will watch these developments closely as resolution approaches.
