Kalshi
The overnight low temperature in Phoenix on June 2, 2026, will be recorded by the National Weather Service according to their daily climatological report.
Prediction market odds on Kalshi reflect real-money consensus from traders betting on Phoenix's lowest temperature on June 2, 2026. These odds often diverge from traditional weather analyst forecasts because markets incorporate diverse trader expectations, risk appetite, and forward-looking sentiment. While meteorologists typically issue point forecasts or confidence ranges, prediction markets express probabilities across multiple temperature outcomes. Comparing the two reveals whether traders are pricing in more or less extreme weather than official forecasts suggest, offering a complementary view of temperature expectations.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, the lowest temperature in Phoenix on June 2, 2026 is priced as a set of binary or range-based contracts, each representing a specific temperature threshold or band. Traders buy or sell shares at prices between 0 and 100 cents, where the price reflects the implied probability of that outcome occurring. As new weather data, seasonal patterns, or climate models emerge, traders adjust their positions, moving prices up or down. The most actively traded contracts typically cluster around historically typical June lows for Phoenix, though unusual atmospheric conditions can shift pricing across the full range.
The market resolves on Jun 3, 2026, after the close of trading on June 2, 2026. Resolution is determined by the actual lowest temperature recorded in Phoenix on that date. Official weather station data—typically from the National Weather Service or equivalent meteorological authority—serves as the authoritative source. Once the day concludes and the minimum temperature is confirmed, the outcome is locked in and all contracts settle according to which temperature band or threshold was reached. Traders holding shares in the correct outcome receive their payout.
Several factors can shift market odds for Phoenix's June 2 low temperature. Updated seasonal climate forecasts and long-range weather models may signal cooler or warmer patterns weeks in advance. Short-term atmospheric changes—such as high-pressure systems, monsoon moisture, or upper-level troughs—can alter expectations as June approaches. Historical temperature anomalies and El Niño or La Niña conditions influence regional summer temperatures. Real-time weather updates in late May and early June will drive the most dramatic repricing. Additionally, any unusual solar activity or volcanic aerosols affecting atmospheric conditions could shift trader sentiment about the final outcome.
