This market will resolve to the temperature range that contains the highest temperature recorded at the Hartsfield-Jackson International Airport Station in degrees Fahrenheit on 25 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Hartsfield-Jackson International Airport Station, available here: https://www.wunderground.com/history/daily/us/ga/atlanta/KATL. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.

Prediction market odds reflect real-money trader conviction and aggregate dispersed information, often diverging from traditional weather forecasts or analyst models. While meteorologists rely on atmospheric data and historical patterns, this market prices outcomes based on collective trader belief and risk appetite. Comparing the current implied probability to official National Weather Service forecasts or seasonal climate models can reveal where the crowd expects conditions to deviate from baseline expectations. Such gaps often signal either market inefficiency or genuine uncertainty that traditional forecasts may underweight.
This market resolves around Jun 25, 2026, once the highest temperature recorded in Atlanta on June 25 becomes verifiable from credible public sources. The outcome is determined by comparing the official daily high to the contract's specified temperature range. Once the event passes and data is confirmed, the market settles automatically, and traders' positions are credited or debited based on whether their prediction matched the realized outcome.
Weather pattern shifts, seasonal climate anomalies, and updated meteorological forecasts are primary catalysts that can shift odds in this market. Major atmospheric systems—such as high-pressure ridges, tropical moisture intrusions, or cold fronts—can significantly alter temperature expectations. Additionally, historical heat records, El Niño or La Niña conditions, and real-time model consensus updates published by the National Weather Service often trigger repricing. As June 25 approaches, intraday forecast refinements and actual observed temperatures in the days leading up to the event will likely drive final price adjustments.
