Kalshi
The minimum overnight temperature in New Orleans on May 30, 2026, will be recorded according to the National Weather Service's daily climatological report.
Prediction market odds on Kalshi reflect aggregated trader beliefs about New Orleans' lowest temperature on May 30, 2026, and often diverge from traditional meteorological forecasts. While weather analysts rely on deterministic models and historical climatology, prediction markets incorporate real-time information, trader expertise, and forward-looking sentiment. Markets may price in tail risks or seasonal anomalies that formal forecasts downweight. Comparing Kalshi odds to National Weather Service seasonal outlooks or private meteorology firms can reveal where traders see value or disagreement with conventional wisdom about late May temperatures in New Orleans.
On Kalshi, the lowest temperature in New Orleans on May 30 is priced as a binary or range-based contract reflecting the probability of specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders buy and sell shares corresponding to different temperature bands, with prices ranging from 0 to 100 cents per share. The contract's value depends on real-time demand, historical volatility in late-May New Orleans weather, and proximity to the resolution date. As May 30 approaches, prices typically tighten around the most likely outcome, and liquidity may shift toward the most probable temperature range.
The market resolves on May 31, 2026, after the lowest temperature in New Orleans on May 30, 2026 has been recorded and verified. Resolution timing allows for official data collection and confirmation from authoritative weather sources. The specific temperature reading that determines the outcome is established by standard meteorological measurement protocols for the New Orleans area on that date. Once the official low is confirmed, the market settles according to which outcome bracket or threshold the recorded temperature falls into, and traders' positions are finalized.
Several factors could shift odds for New Orleans' May 30 low temperature. Major weather pattern changes—such as shifts in the jet stream, tropical system development, or anomalous high or low pressure systems—will influence trader expectations. Updated seasonal forecasts from NOAA or other meteorological agencies may alter market pricing. Historical analogs and climate indices like the Atlantic Multidecadal Oscillation or El Niño status could sway sentiment. As May 2026 approaches, real-time weather models will become more precise, typically narrowing the range of plausible outcomes and concentrating trading activity around the most probable low temperature.
