This event tracks the highest temperature recorded in Oklahoma City on June 28, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, which provides the authoritative maximum temperature measurement for the location.
Resolution is based on the maximum temperature recorded at Oklahoma City Will Rogers Airport on June 28, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS regional climate portal for the Oklahoma City office. Temperature ranges are divided into six bands: 93°F or below, 94-95°F, 96-97°F, 98-99°F, 100-101°F, and 102°F or above. Each temperature band corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution. While secondary sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) serves as the authoritative source for determining the actual outcome.
Prediction market odds reflect aggregated trader expectations and often incorporate real-time data faster than traditional weather forecasts. While meteorologists and climate analysts publish seasonal outlooks and historical temperature trends for Oklahoma City in late June, this market prices in collective market intelligence from participants actively betting on the outcome. Comparing the implied probability here to published analyst consensus can reveal where traders see divergence from official forecasts, though both sources draw from similar underlying climate and atmospheric data.
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. The bid-ask spread reflects the current liquidity and conviction among participants; tighter spreads indicate higher confidence and trading activity, while wider spreads suggest uncertainty or lower volume. As new weather models, seasonal data, and real-time atmospheric conditions emerge, traders adjust their positions, moving the price to reflect updated expectations for the June 28 high.
This market resolves around Jun 29, 2026, once the actual highest temperature recorded in Oklahoma City on June 28, 2026 is verified and confirmed. The outcome is determined by comparing the day's official temperature reading against the market's predefined outcome brackets or thresholds. Resolution occurs after the event date when credible public reporting of the temperature is available, allowing traders' positions to settle based on the verified result.
Major weather pattern shifts, updated seasonal climate forecasts, and historical temperature anomalies for Oklahoma City in late June can all influence trader positioning. El Niño or La Niña developments, changes in atmospheric pressure systems, and long-range model updates from meteorological agencies may trigger repricing. Additionally, real-time heat waves or cold snaps in the weeks leading up to June 28 could shift expectations about regional temperature extremes, causing sharp movements in this market as traders adjust their bets based on evolving conditions.
