Description

This market tracks the highest temperature recorded in Phoenix on July 10, 2026, using official National Weather Service data from Phoenix, Arizona. The outcome will be determined by the maximum temperature reading on that specific date.

Kalshi

Resolution is based on the maximum temperature recorded at Phoenix, AZ on July 10, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 108°F or below, 109-110°F, 111-112°F, 113-114°F, 115-116°F, and 117°F or above. Each range corresponds to a distinct outcome. Official data must be obtained from the NWS Climatological Report via the specified URL, selecting Phoenix, AZ with Daily Climate Report. While preliminary NWS data and third-party weather sources may provide guidance, the final determination uses only the official NWS Climatological Report (Daily) values. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect the final reading.

Frequently asked questions

On Kalshi, the Phoenix heat record market dashboard displays real-time odds and trading activity for the highest temperature prediction in Phoenix on July 10, 2026. The interface shows current market prices, 24-hour volume of $41,951, and historical price movements as traders adjust their positions based on weather forecasts and seasonal climate data. Total volume across this market stands at $48,285, reflecting ongoing trader interest in extreme heat outcomes for that specific date.

Prediction market odds often diverge from traditional meteorological forecasts because traders incorporate broader information—including climate patterns, historical precedent, and real-time atmospheric data—into their pricing. While weather analysts issue point estimates or confidence intervals, this market aggregates collective trader expectations into live probabilities. Comparing the two reveals whether the crowd is pricing in more or less tail risk than official forecasts suggest, offering a complementary lens on extreme heat likelihood.

This market resolves around Jul 11, 2026, once July 10, 2026 has passed and the highest temperature recorded in Phoenix that day is confirmed. The outcome is determined by verified public reporting of the actual maximum temperature, ensuring all traders reference the same factual record. Positions are settled based on which temperature bracket or range the final reading falls into, with payouts distributed accordingly.

Major climate forecasts, seasonal pattern updates, and long-range weather models will influence trader positioning as July 2026 approaches. El Niño or La Niña conditions, atmospheric pressure systems, and historical heat wave data serve as key catalysts. Additionally, any shift in Phoenix's urban heat island effect or unexpected atmospheric anomalies could prompt sharp repricing. Traders monitor both meteorological institutes and real-time atmospheric indicators to adjust their exposure ahead of the settlement date.
