This market tracks the lowest temperature recorded in Phoenix on June 12, 2026. The outcome is determined by the daily minimum temperature reported by the National Weather Service for Phoenix, Arizona, divided into six temperature bands ranging from 75°F or below to 84°F or above.
Resolution is based on the minimum temperature recorded at Phoenix on June 12, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Phoenix, AZ. The official data source is accessed via the NWS Phoenix office website under the Observed Weather tab. Temperature bands are: 75°F or below, 76-77°F, 78-79°F, 80-81°F, 82-83°F, and 84°F or above. 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.
Prediction market odds reflect real-money commitments from traders and often diverge from traditional weather forecasts issued by meteorologists and climate analysts. While meteorological models rely on atmospheric data and historical patterns, this market aggregates the beliefs of participants who have financial incentive to be accurate. Comparing the implied probability here to official forecasts from the National Weather Service or other agencies can reveal where the crowd sees risk differently than institutional experts.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different temperature ranges or outcomes. 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 outcome, and the current bid-ask spread reflects the tightest prices at which traders are willing to transact. As new information emerges or trading interest shifts, prices adjust in real time, allowing you to enter or exit positions at market rates.
This market resolves around Jun 13, 2026, once the lowest temperature recorded in Phoenix on June 12, 2026 is verified against credible public sources. The outcome is determined by official meteorological data, typically from the National Weather Service or equivalent weather monitoring authority. Traders' positions settle based on which temperature bracket or outcome the actual low falls into, with payouts distributed accordingly once the event is confirmed.
Major weather pattern shifts, seasonal climate anomalies, and long-range forecast updates from meteorological agencies can all influence trading activity in this market. El Niño or La Niña conditions, volcanic activity, or unusual solar cycles may alter expectations for June temperatures in the Southwest. As the event date draws closer, weekly and daily forecasts become more precise, typically triggering repricing. Real-time atmospheric data and any unusual heat or cold events in the months leading up to June 2026 will likely drive trader repositioning.
