This market tracks the lowest overnight temperature recorded in Los Angeles on July 5, 2026. Resolution uses the official National Weather Service Climatological Report (Daily) for Los Angeles Airport, which may differ from other weather sources due to measurement methodology and rounding conventions.
Resolution is determined by the minimum temperature recorded at Los Angeles Airport on July 5, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Los Angeles NWS office. The official temperature is divided into six ranges: 55°F or below, 56-57°F, 58-59°F, 60-61°F, 62-63°F, and 64°F or above. Each range corresponds to a separate market outcome. 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 takes precedence over other weather sources such as AccuWeather or Google Weather.
Prediction market odds reflect real-time consensus from traders with financial incentives to forecast accurately, often diverging from traditional meteorologist models or seasonal averages. While weather analysts rely on atmospheric data and historical patterns, this market aggregates the collective judgment of participants betting on the actual outcome. Comparing the two reveals whether traders are pricing in factors analysts may underweight—such as unusual climate patterns or recent anomalies—or whether they are more conservative. Over time, prediction market prices tend to incorporate new information faster than published forecasts update, making them a useful barometer of evolving expectations.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell contracts representing 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 current supply and demand for each outcome, with prices ranging from near zero to near 100 cents per contract. As new information emerges or trader sentiment shifts, prices adjust dynamically. Participants profit by correctly predicting the lowest temperature, incentivizing accurate pricing and deep liquidity across the outcome space.
This market resolves around Jul 6, 2026, once the lowest temperature recorded in Los Angeles on July 5, 2026 is verifiable from credible public sources. The outcome is determined by official meteorological data, typically from the National Weather Service or equivalent authoritative weather reporting. Traders' positions settle based on which temperature bracket or specific outcome occurred on that date. Resolution is automatic once the data is confirmed and published.
Major climate patterns, seasonal forecasts, and atmospheric anomalies published by meteorological agencies can shift trader expectations significantly. El Niño or La Niña conditions, unusual jet-stream positioning, or heat-wave warnings may push prices higher or lower depending on their implied effect on July temperatures. Real-time weather updates closer to the event date typically trigger sharp repricing as uncertainty narrows. Long-range climate models and any unusual solar or oceanic activity could also influence how traders position themselves. As the event date approaches, intraday weather reports become increasingly important drivers of market movement.
