This market tracks the overnight low temperature in Los Angeles on July 6, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Los Angeles International Airport, which records the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Los Angeles on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily) accessible via the Los Angeles NWS office. The official data source is the NWS Daily Climate Report for Los Angeles Airport, CA, available through the specified NWS regional office portal. 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 for resolution. While secondary sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) value is used for final determination.
Prediction market odds often diverge from traditional meteorological forecasts because they reflect real-money trader conviction rather than statistical models alone. While weather analysts rely on atmospheric data and historical patterns, this market incorporates broader information—including trader expertise, recent climate trends, and event-specific factors. Over time, prediction markets have demonstrated competitive accuracy against expert forecasts, particularly when liquidity is high and diverse participants contribute their knowledge. Comparing odds here to published forecasts from meteorological services can reveal where the crowd sees asymmetric risk.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit buy and sell orders for outcome shares. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the marginal probability traders assign to it; higher prices indicate greater collective confidence in that temperature range occurring. Traders profit by correctly predicting the lowest temperature, and the bid-ask spread represents the current disagreement between buyers and sellers about the true probability.
This market resolves around Jul 7, 2026, once July 6, 2026 has passed and the day's lowest temperature can be verified. The outcome is confirmed against credible public sources reporting the actual low temperature recorded in Los Angeles on that date. Traders holding shares in the correct outcome band receive their payout, while incorrect positions expire worthless. The resolution process is automatic once the verified temperature data becomes available.
Several factors could shift odds significantly before resolution. Updated seasonal forecasts, El Niño or La Niña patterns, and long-range climate models may influence trader expectations. Major weather systems approaching Southern California in early July would trigger sharp repricing. Historical temperature records for that date and recent heat or cold trends in the region also inform positioning. As July 6, 2026 approaches, short-term meteorological forecasts will become increasingly precise, likely narrowing the range of plausible outcomes and concentrating liquidity around the most probable temperature band.
