This market tracks the highest temperature recorded in Oklahoma City on June 13, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which provides the authoritative maximum temperature measurement for the city.
Resolution is based on the maximum temperature recorded at Oklahoma City Will Rogers Airport on June 13, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website at the provided URL, selecting the "Observed Weather" tab and "Oklahoma City Will Rogers Airport" location with Daily Climate Report. 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 other weather sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) serves as the authoritative source for determining the outcome.
Prediction market odds reflect real-money consensus from traders who profit or lose based on accuracy, creating a strong incentive for honest price discovery. Traditional weather forecasters and meteorological models publish deterministic or probabilistic temperature predictions, but they do not carry financial stakes. This market aggregates dispersed trader knowledge—including access to private weather data, historical patterns, and regional climate expertise—into a single probability estimate. When analyst forecasts and market odds diverge significantly, it often signals either new information traders have priced in or an opportunity for informed participants to arbitrage the gap.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome bracket has its own bid-ask spread, and the midpoint of the tightest spread reflects the marginal trader's belief about that outcome's probability. As new information arrives—updated weather forecasts, seasonal data, or real-time atmospheric conditions—traders adjust their positions, moving prices up or down. The platform's matching engine executes trades instantly, ensuring prices remain responsive to market conditions.
This market resolves around Jun 14, 2026, once the highest temperature recorded in Oklahoma City on June 13, 2026 is verified and confirmed. The outcome is determined by comparing the final recorded high against the outcome brackets offered in the market, with winning shares paid out according to which bracket contains the verified temperature. Resolution occurs after the event date has passed and credible public reporting has established the definitive temperature reading. Traders holding shares in the correct bracket receive their payout proportional to the market's final odds.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can significantly move prices in this market. El Niño or La Niña conditions, changes in jet-stream positioning, and historical heat-wave patterns for early June in Oklahoma will influence trader positioning. Real-time atmospheric data released closer to the event date—such as high-pressure system development or moisture availability—typically triggers sharp repricing. Additionally, any unusual climate events or record-breaking temperatures in neighboring regions may prompt traders to adjust their Oklahoma City forecasts upward or downward.
