This market tracks the lowest temperature recorded in Los Angeles on July 1, 2026. The outcome is determined by the minimum temperature reading from the National Weather Service's official daily climatological report for that date.
Resolution is based on the minimum temperature recorded at Los Angeles Airport, CA on July 1, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six bands: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, and 61°F or above, with each band corresponding to a distinct 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 data sources.
Prediction market odds reflect real-money incentives, so traders who misjudge conditions face direct financial loss. This creates a powerful mechanism for aggregating dispersed information. Meteorologists and climate analysts publish seasonal forecasts and historical temperature patterns for Los Angeles, but they typically issue ranges and probabilities rather than binary outcomes. This market distills those expert views—plus trader research and real-time data—into a single price. When odds diverge sharply from published forecasts, it often signals either new information the broader analyst community hasn't yet incorporated, or an opportunity for informed traders.
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 market's confidence in each outcome; tighter spreads indicate consensus, while wider spreads suggest uncertainty. As new weather models, historical data, or seasonal patterns become available, traders adjust their positions, moving the price. You can place limit or market orders to express your view on the lowest temperature Los Angeles will experience on that date.
This market resolves around Jul 2, 2026, once the event has occurred and the outcome is verifiable from credible public sources. The lowest temperature recorded in Los Angeles on July 1, 2026 will determine which outcome is correct. Traders who backed the accurate temperature range or threshold will receive their winnings, while incorrect positions expire worthless. The resolution process is automated once the data is confirmed, ensuring all traders receive payouts fairly and transparently.
Updated seasonal climate forecasts, El Niño or La Niña patterns, and long-range weather models will all influence trader expectations and shift odds. Major atmospheric events—such as heat waves or unusual cold fronts affecting California—can trigger repricing. Historical temperature records and anomalies for early July in Los Angeles provide a baseline, but any shift in climate indices or meteorological outlooks may prompt traders to adjust positions. As July 1, 2026 approaches, short-range forecasts become more reliable and typically narrow the range of plausible outcomes, tightening the market.
