Weather prediction markets on specific daily temperature ranges offer traders price discovery on meteorological outcomes. Chicago's highest temperature on April 18 can be objectively verified through official National Oceanic and Atmospheric Administration (NOAA) data, making it clearly resolvable. The specific range of 60-61°F represents a narrow band within Chicago's typical April temperature variation. Currently, YES odds are priced at just 5%, implying that market participants believe there is a low probability the daily high will fall exactly within this two-degree window on April 18. This reflects the inherent difficulty in predicting precise temperature outcomes in weather markets—on any given day, most outcomes will fall outside any narrow range. Historical April weather patterns for Chicago show daily highs typically ranging from the mid-40s to the mid-60s Fahrenheit, making the 60-61°F range climatologically plausible but not the most probable outcome for any single day. Market odds may shift as April 18 approaches and meteorological forecasts become increasingly refined. Resolution will be determined by the official NOAA recorded high temperature for Chicago on April 18, compared directly against the 60-61°F range specified in this market.
