This market tracks the lowest temperature recorded in Phoenix on June 27, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Phoenix, which measures the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Phoenix, Arizona on June 27, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Southwest Region Climate portal by selecting the Phoenix, AZ location with Daily Climate Report. The minimum temperature is divided into six distinct ranges: 76°F or below, 77-78°F, 79-80°F, 81-82°F, 83-84°F, and 85°F or above. Each range corresponds to a separate market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services or preliminary reports.
Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader sentiment and risk appetite alongside meteorological data. While meteorologists issue probabilistic forecasts based on atmospheric models, this market aggregates the collective judgment of traders who have financial incentive to price outcomes accurately. Comparing the current odds to published forecasts from the National Weather Service or other weather agencies can reveal whether traders are pricing in more or less downside risk than official models suggest. This divergence frequently highlights where public expectations differ from expert consensus.
On Kalshi, this market is priced through a continuous order book where traders submit bids and asks for shares tied to the outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each share represents a claim on the payout if the lowest temperature in Phoenix on June 27, 2026 settles below 77 degrees. The market price reflects the equilibrium between buyers and sellers; as new information emerges or trader conviction shifts, the odds adjust in real time. Participants can enter or exit positions throughout the trading window, and the platform's matching engine executes trades at the best available prices.
This market resolves around Jun 28, 2026, once the lowest temperature recorded in Phoenix on June 27, 2026 is verified against credible public sources. The outcome is binary: if the minimum temperature falls below 77 degrees, one side of the market pays out; if it remains at or above that threshold, the other side prevails. Resolution timing depends on when official temperature data becomes available and is confirmed by the platform. Traders should monitor weather reporting from reliable meteorological authorities as the event date approaches.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can all influence trader positioning in this market. As June 2026 approaches, medium-range weather models will become more reliable, potentially triggering significant price moves if they show unexpected heat or cooling trends. Broader climate events—such as La Niña or El Niño conditions—may also affect Arizona's temperature outlook. Additionally, any revisions to historical temperature records or changes in how official measurements are taken could alter trader expectations about what constitutes the final outcome.
