The event tracks the highest temperature in Chicago on August 28, 2026, categorizing outcomes into six distinct temperature ranges from below 79°F up to 88°F or above. Each range has specific criteria for resolution based on official weather data.
The event resolves based on the maximum temperature recorded at Chicago (CLIMDW) on August 28, 2026, as reported by The Weather Company. Six markets correspond to temperature ranges: less than 80°F, 80-81°F, 82-83°F, 84-85°F, 86-87°F, and greater than 87°F. If the recorded temperature falls within a specific range, the corresponding market resolves to Yes. All secondary rules emphasize that The Weather Company’s data is the sole authority, cautioning users about potential discrepancies in preliminary readings from other sources due to rounding or conversion differences.
