This market tracks the lowest temperature recorded in Oklahoma City on July 10, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Oklahoma City Will Rogers Airport, which measures the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Oklahoma City Will Rogers Airport on July 10, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Southern Region Climate portal under the Oklahoma City Will Rogers Airport location with Daily Climate Report selected. 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 resolution source.
Prediction market odds reflect aggregated trader expectations and often diverge from traditional meteorologist forecasts because they incorporate real-time information and financial incentives for accuracy. While weather analysts publish deterministic low-temperature predictions based on atmospheric models, this market prices uncertainty across multiple outcome ranges. Comparing the two reveals whether traders are more bullish or bearish on extreme cold than official forecasts suggest. Over time, prediction markets have proven competitive with or superior to single-model predictions for weather events, especially when participants have skin in the game.
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 contract trades independently, and the price of a share reflects the collective belief in that outcome's probability. Traders profit by correctly predicting the actual low temperature on the specified date, and the bid-ask spread tightens as volume increases and consensus strengthens around likely outcomes.
This market resolves around Jul 11, 2026, once the actual lowest temperature recorded in Oklahoma City on July 10, 2026 is confirmed and verifiable from credible public sources. The outcome is determined by comparing the recorded low against the temperature thresholds defined in each contract. Traders holding shares in the correct range receive their payout, while incorrect predictions result in a loss. Resolution is typically finalized within hours of the market close once official data is published.
Major weather pattern shifts, updated seasonal forecasts, and atmospheric anomalies can significantly move odds in this market. Tropical systems, polar vortex disruptions, or unexpected high-pressure systems over Oklahoma could all trigger repricing. Real-time model updates from the National Weather Service and other meteorological agencies often prompt trader repositioning. Additionally, historical temperature records and climate data releases may influence long-term expectations. As July 2026 approaches, short-term forecast updates and actual early-summer weather trends will drive the most volatile price swings.
