This market tracks the overnight low temperature in Oklahoma City on July 8, 2026, as recorded by the National Weather Service at Will Rogers Airport. The outcome will be determined by the official NWS Climatological Report (Daily), which may differ from other weather sources due to measurement methods and rounding conventions.
Resolution is based on the minimum temperature recorded at Oklahoma City Will Rogers Airport on July 8, 2026, according to the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 65°F or below, 66-67°F, 68-69°F, 70-71°F, 72-73°F, and 74°F or above. Each range corresponds to a distinct market outcome. Data must be obtained from the official NWS source at the specified URL, navigating to the Observed Weather tab and selecting Oklahoma City Will Rogers Airport with Daily Climate Report. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the official final value from the NWS Climatological Report (Daily) takes precedence over other weather services.
Prediction market odds reflect aggregated trader expectations and often diverge from traditional meteorologist forecasts because markets incorporate real-time information, uncertainty premiums, and diverse participant views. While weather analysts issue point forecasts or ranges based on atmospheric models, this market prices the probability of specific temperature thresholds, allowing traders to express nuanced views on tail risks and model disagreement. Over time, prediction markets have shown competitive accuracy against expert forecasts, particularly when liquidity is sufficient and participants have strong incentives to forecast accurately.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to 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 market's liquidity and uncertainty; tighter spreads indicate higher confidence and trading activity, while wider spreads suggest lower participation or genuine disagreement among traders. Prices range from 0 to 100 cents per share, with each cent representing a 1% probability increment, making it intuitive to compare market-implied odds across competing temperature bands.
This market resolves around Jul 9, 2026, once the lowest temperature recorded in Oklahoma City on July 8, 2026 is verified against credible public sources. The outcome is determined by the actual low temperature reported for that date, measured in degrees Fahrenheit according to standard meteorological conventions. Traders holding shares in the outcome band that contains the verified temperature receive their payout, while other positions expire worthless.
Major weather pattern shifts, updated seasonal forecasts, and real-time atmospheric data releases can significantly move this market. Tropical systems, heat domes, or cold fronts approaching Oklahoma in early July would trigger repricing as traders adjust expectations. Additionally, historical analogues—such as past July heat waves or cool spells—may influence sentiment. As the event date approaches, short-range forecast models become more reliable and typically narrow the range of plausible outcomes, often causing the market to consolidate around a tighter probability distribution.
