The event tracks whether Denver experiences at least two consecutive days with average temperatures above 90°F during the week of August 31 to September 6, 2026. It examines heat patterns over a specific period to determine if such a temperature streak occurs.
Multiple markets assess consecutive days of average temperature above 90°F in Denver from August 31 to September 6, 2026. Each market specifies a minimum number of consecutive days (ranging from 2 to 6 days) required for a 'Yes' outcome. A day's average temperature is 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 whole degree. Only days within the specified date range count toward a streak. A day with an average of exactly 90°F does not satisfy the condition, and any day with fewer than 18 reported hourly values breaks the streak. Data used for resolution is as published at the Expiration Time, with later revisions disregarded.
Currently, this market reflects trader expectations through its probability pricing, which can diverge from or align with analyst forecasts. Analysts may issue reports on regional weather patterns, historical trends, or climate models that influence public sentiment. When their projections differ from the market’s implied probability, it often signals an opportunity for traders to react to new information. Comparing this market’s odds to expert outlooks provides a useful barometer of collective investor confidence versus institutional or scientific predictions.
This market resolves around Sep 8, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, official meteorological data will be used to count the number of consecutive days with an average temperature above 90°F in Denver during the week of Aug 31, 2026. The result is binary — either the streak meets the threshold or it does not — and is settled based on publicly available records.
Several signals could shift this market before resolution. Updates from major weather forecasting services, sudden shifts in long-range climate models, or extreme early-season heat events in the region may cause traders to reassess probabilities. Additionally, unexpected atmospheric patterns such as El Niño developments or unusual jet stream behavior could influence expectations. Any widely reported deviation from historical norms will likely trigger volatility as participants react to new data.
