This market tracks the overnight low temperature in Los Angeles on June 30, 2026, divided into six temperature bands. The outcome will be determined by the official National Weather Service daily climatological report for Los Angeles Airport.
Resolution is based on the minimum temperature recorded at Los Angeles on June 30, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Los Angeles Airport, CA. The official data source is accessed through the NWS website at the specified URL under the Observed Weather tab. Temperature bands are: 55°F or below, 56-57°F, 58-59°F, 60-61°F, 62-63°F, and 64°F or above. Each band resolves to Yes if the recorded minimum falls within its range. 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 readings or third-party weather services.
Prediction market odds reflect real-money incentives that often reveal trader confidence diverging from published analyst forecasts. While meteorologists issue seasonal outlooks and historical climate normals for Los Angeles, this market aggregates dispersed knowledge from participants who profit only if their temperature prediction proves correct. Analyst forecasts tend toward consensus ranges, whereas market odds can price in tail risks or unusual patterns that traditional models underweight. The comparison highlights how financial skin-in-the-game sometimes surfaces insights that pure statistical models miss, though both approaches draw on the same underlying climate and weather data.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract reflects the probability traders assign to that temperature band occurring, with prices ranging from near-zero to near-unity. As new information arrives—seasonal forecasts, atmospheric patterns, or real-time weather updates—traders adjust bids and asks, moving the price to equilibrate supply and demand. The spread between buy and sell prices tightens as the event date approaches and uncertainty narrows.
This market resolves around Jul 1, 2026, once June 30, 2026 has passed and the lowest temperature recorded in Los Angeles that day is verifiable from credible public sources. The outcome is determined by comparing actual recorded temperatures against the predetermined ranges offered in the market. Resolution hinges on official meteorological data, typically from established weather stations or national weather services, ensuring an objective and transparent settlement. Traders' positions are settled based on which temperature band the verified low falls into.
Long-range climate oscillations—such as El Niño or La Niña patterns—can shift seasonal temperature expectations for Southern California and move odds significantly. Major atmospheric blocking patterns or heat dome formations reported months in advance may trigger repricing as traders adjust for unusual warmth. Seasonal trend data released by meteorological agencies often sparks trading activity. As June 2026 approaches, real-time weather forecasts become more precise, typically narrowing the range and concentrating liquidity around the most likely outcome. Unexpected volcanic activity or solar variations could also influence stratospheric conditions, though such events remain rare catalysts for this particular market.
