This market tracks the lowest temperature recorded in Oklahoma City on July 2, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Oklahoma City Will Rogers Airport, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at Oklahoma City Will Rogers Airport on July 2, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website by navigating to the Observed Weather tab and selecting Oklahoma City Will Rogers Airport with Daily Climate Report. The reported minimum temperature will fall into one of six temperature bands: 69°F or below, 70-71°F, 72-73°F, 74-75°F, 76-77°F, or 78°F and above. 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 rather than preliminary estimates or third-party weather services.
Prediction market odds reflect real-money incentives for accuracy, often diverging from traditional weather analyst forecasts because traders incorporate a broader range of data sources and risk adjustments. While meteorologists publish deterministic forecasts based on numerical models, this market aggregates the beliefs of many participants betting their capital on the outcome. Analyst forecasts tend to be issued closer to the event date and may carry institutional confidence intervals, whereas market odds update continuously as new information arrives, sometimes leading to earlier or more extreme probability shifts than official predictions.
On Kalshi, this market is priced through an 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 market's uncertainty; wider spreads indicate less consensus, while tighter spreads suggest stronger agreement on the likely low temperature. Prices move as new orders flow in, with each trade updating the marginal probability. Traders can enter limit or market orders to express their views on whether the actual low will fall within specified bands, and the platform's matching engine continuously clears trades at negotiated prices.
This market resolves around Jul 3, 2026, after July 2, 2026 has passed and the actual low temperature for Oklahoma City can be verified. The outcome is determined by comparing the recorded minimum temperature against the predefined outcome brackets or thresholds established at market creation. Once credible public reporting confirms the official low, the market settles and winning positions are credited. Traders should monitor weather station data and official meteorological records in the days following the event to understand how their positions will be adjudicated.
Major weather pattern shifts, updated seasonal climate outlooks, and long-range forecast model runs can significantly move this market. Tropical activity, jet stream positioning, and high-pressure system development over the Great Plains are key catalysts that traders monitor. Additionally, historical temperature anomalies for early July and any El Niño or La Niña signals influence expectations. As the event date approaches, medium-range forecasts become more precise, typically triggering sharper price movements. Real-time atmospheric data releases and any unusual heat or cold events in neighboring regions may also prompt traders to reassess their positions.
