This market tracks the highest temperature recorded in Oklahoma City, Oklahoma on June 17, 2026. The outcome is determined by the daily maximum temperature reported by the National Weather Service's official Climatological Report, with resolution based on which temperature range the recorded high falls within.
Resolution is determined by the maximum temperature recorded at Oklahoma City on June 17, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Oklahoma City NWS office climate data portal using Oklahoma City Will Rogers Airport as the reporting location. The official temperature data source is the NWS Daily Climate Report, which should be consulted in its latest version as of the resolution date. Traders should be aware that preliminary NWS reporting may be subject to rounding and conversion nuances that could affect final values. While secondary sources like AccuWeather or Google Weather may provide guidance, only the official NWS Climatological Report (Daily) constitutes the authoritative data for market resolution.
Prediction market odds reflect real-time trader conviction and aggregate dispersed information from thousands of participants, whereas traditional weather forecasts rely on meteorological models and expert analysis. This market synthesizes expectations about atmospheric conditions, seasonal patterns, and climate trends into a single probability estimate. While meteorologists publish deterministic forecasts days or weeks ahead, prediction markets allow continuous repricing as new data emerges, often capturing nuances that static forecasts miss. Both approaches offer value: markets excel at capturing tail risks and shifting sentiment, while analysts provide detailed physical reasoning.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing different temperature 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 balance of supply and demand; tighter spreads indicate high confidence and liquidity, while wider spreads suggest uncertainty or lower trading interest. Prices range from 0 to 100 cents per share, with each cent representing a 1% probability increment. As traders place orders, prices adjust dynamically to clear the market and reflect evolving expectations about June 17 conditions in Oklahoma City.
This market resolves around Jun 18, 2026, after June 17, 2026 has concluded. The outcome is determined by the verified highest temperature recorded in Oklahoma City on that date, confirmed once the event is observable from credible public reporting. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. Resolution timing allows sufficient time for official temperature data to be published and cross-checked, ensuring accuracy and fairness for all participants.
Major weather pattern shifts, seasonal forecasts, and long-range climate models can significantly influence trader positioning. Announcements of heat waves, drought conditions, or unusual atmospheric blocking patterns typically drive prices upward for hotter outcomes. Conversely, predictions of cooler-than-normal patterns or increased cloud cover may lower odds. Real-time weather updates in the days immediately before June 17 often trigger sharp repricing as traders incorporate the latest data. Historical temperature records for that date and time of year also serve as reference points that anchor expectations and guide trading decisions.
