Description

This event tracks the highest temperature reached in Phoenix on a specific future date, using official government data. Participants assess whether conditions will lead to certain temperature ranges being met or exceeded on that day.

Kalshi

All markets resolve based solely on the maximum temperature recorded in Phoenix on August 12, 2026, as officially reported by the National Weather Service's 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 is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may offer guidance, only the NWS figure determines resolution. Traders should be aware that NWS data may include rounding or conversion nuances, and reports across locations may update at different frequencies, requiring careful verification of the official figure.
