This market tracks the lowest temperature recorded in New Orleans on July 11, 2026. The outcome will be determined by the official National Weather Service daily climatological report for New Orleans, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at New Orleans, LA on July 11, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Southern Region Climate portal by selecting New Orleans with the Daily Climate Report option. Traders should use the latest available version of the data for the specified date. While preliminary NWS data and alternative weather sources like AccuWeather or Google Weather may provide guidance, the final authoritative value is determined exclusively by the NWS Climatological Report (Daily). Preliminary NWS reporting may be subject to rounding and conversion nuances that could affect interpretation of borderline values.
Prediction market odds reflect aggregated trader expectations and often diverge from traditional meteorological forecasts. While weather analysts rely on numerical models and historical climate data, this market incorporates real-time information and trader conviction through price discovery. Comparing the two reveals whether the crowd is pricing in more or less risk than official forecasts suggest. Over time, prediction markets have demonstrated competitive accuracy for weather events, particularly when traders have access to the same underlying data as analysts. Monitoring both sources helps identify where consensus breaks down and where outlier outcomes may be underpriced.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to specific temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, and the price of a share reflects the collective probability assigned by active traders. Bid-ask spreads tighten as volume increases, rewarding liquidity providers and allowing larger positions to execute with lower slippage. The platform's matching engine ensures transparent price discovery, with all trades recorded on the public order history. Traders can enter limit or market orders to express their view on the lowest temperature outcome.
This market resolves around Jul 12, 2026, once the event concludes and the lowest temperature for July 11, 2026 in New Orleans is verifiable from credible public sources. The outcome is determined by comparing actual recorded temperatures against the predefined brackets offered in the market. Resolution typically occurs within hours of the official close of the trading day, after meteorological data has been confirmed and published. Traders holding shares in the correct outcome bracket receive their payout automatically, while incorrect positions expire worthless. The exact timing depends on data availability and platform processing.
Major weather pattern shifts, updated seasonal forecasts, and tropical system developments could significantly alter odds in this market. As summer 2026 approaches, traders will incorporate new climate models, historical analogues, and real-time atmospheric conditions into their pricing. Unexpected heat waves or cool fronts in the weeks leading up to July could trigger sharp repricing. Media coverage of extreme weather elsewhere may also influence trader sentiment about regional temperature extremes. Additionally, any significant changes to New Orleans' urban heat island effect or local infrastructure could shift baseline expectations. Continuous monitoring of meteorological updates and market activity helps traders identify turning points.
