This market tracks the lowest overnight temperature recorded in Los Angeles on June 29, 2026. The outcome is determined by the official National Weather Service daily climatological report for Los Angeles Airport, which provides the minimum temperature reading for that specific date.
Resolution is based on the minimum temperature recorded at Los Angeles Airport on June 29, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Los Angeles, CA. The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six bands: 53°F or below, 54-55°F, 56-57°F, 58-59°F, 60-61°F, and 62°F or above. Each temperature range corresponds to a separate market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
Prediction market odds reflect aggregated trader expectations and often incorporate the same meteorological models that professional forecasters use, though they may diverge based on how traders weight uncertainty and tail risks. While weather analysts publish seasonal temperature ranges and historical averages for late June in Los Angeles, this market prices in real-time adjustments as traders respond to updated atmospheric conditions and long-range forecasts. The market-implied probability can serve as a useful benchmark against traditional forecasts, though each source—whether a meteorologist or the collective market—brings different strengths in capturing the full distribution of possible outcomes.
On Kalshi, this market is priced through a continuous 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 current balance of supply and demand; tighter spreads indicate higher confidence and liquidity, while wider spreads suggest greater uncertainty or lower participation. As new weather data becomes available or seasonal patterns shift, traders adjust their positions, moving the price up or down to reflect changing probabilities. This dynamic pricing ensures the market continuously incorporates the latest information available to participants.
This market resolves around Jun 30, 2026, once the lowest temperature recorded in Los Angeles on June 29, 2026 can be verified from credible public sources. The outcome is determined by official meteorological data, typically from the National Weather Service or equivalent authoritative weather reporting. Resolution occurs after the trading window closes and the actual temperature reading is confirmed, ensuring all participants have access to the same factual basis for settlement. Traders should monitor weather updates as the date approaches to refine their positions based on the latest forecasts.
Major weather pattern shifts—such as changes in high-pressure systems, marine layer intensity, or upper-atmosphere dynamics—can significantly move this market. Updated seasonal forecasts, El Niño or La Niña developments, and real-time atmospheric models released by meteorological agencies will influence trader positioning. Historical temperature anomalies for late June and any unusual climate events in the months leading up to the date may also shift expectations. As June 29 approaches, daily weather forecasts become increasingly precise, typically causing the market to converge toward the most likely outcome. Traders should track both long-range climate patterns and short-term forecast updates to stay ahead of price movements.
