This market tracks the lowest temperature recorded in Los Angeles on July 10, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on which temperature range the recorded minimum falls into.
Resolution is determined by the minimum temperature recorded at Los Angeles Airport on July 10, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Los Angeles Airport, CA location on the NWS website. The official data source is the NWS Climatological Report rather than preliminary reports or third-party weather services. Temperature measurements may be subject to rounding and conversion nuances in preliminary NWS data, so traders should verify against the final official report. Each outcome corresponds to a specific temperature range: 59°F or below, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or 68°F and above.
Prediction market odds reflect aggregated trader expectations and often diverge from traditional weather forecasts issued by meteorologists and climate analysts. While meteorological models rely on atmospheric physics and historical data, this market incorporates real-time information and trader conviction through price discovery. Comparing the implied probability from market odds to published forecasts from the National Weather Service or other agencies can reveal where traders expect conditions to deviate from official predictions, making this a useful cross-check for understanding competing views on July 10th's low temperature.
On Kalshi, this market is priced through continuous order-book trading, where buyers and sellers set bid and ask prices for each temperature outcome bracket. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders profit by correctly predicting whether the actual low will fall into their chosen range, with payouts determined by the final verified temperature reading. The spread between bid and ask reflects market uncertainty; tighter spreads indicate high confidence in a particular outcome, while wider spreads suggest disagreement about where the low will land.
This market resolves around Jul 11, 2026, once the lowest temperature recorded in Los Angeles on July 10, 2026 is confirmed and verifiable from credible public sources. The outcome is determined by the actual observed low for that calendar day, measured in degrees Fahrenheit according to standard meteorological reporting. Traders holding positions in the outcome bracket matching the verified temperature receive their payout, while other positions expire worthless.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can significantly move odds in this market. Tropical systems, heat domes, or unusual atmospheric blocking patterns developing weeks or months before July 2026 would trigger repricing as traders adjust expectations. Historical temperature records for Los Angeles in early July, El Niño or La Niña conditions, and broader climate trends also influence positioning. As the event date approaches, daily forecast updates and real-time atmospheric data will drive increasingly volatile trading.
