This event tracks whether Austin, Texas will experience extreme heat on a specific summer day in 2026. The outcome depends on official temperature readings from a trusted government weather agency. Participants can speculate on how high temperatures might climb during that period.
All markets resolve based solely on the highest temperature recorded at Austin Bergstrom International Airport on July 30, 2026, as documented in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 98°F, 98–99°F, 100–101°F, 102–103°F, 104–105°F, or above 105°F. The NWS report serves as the definitive source, overriding any other weather data or preliminary readings. Traders must recognize that early or unofficial data may differ due to rounding, conversion, or reporting delays, and only the final NWS entry determines resolution. All secondary rules emphasize reliance on this authoritative source and caution regarding interim data interpretation.
