Frequently asked questions

On Kalshi, the lowest temperature in Chicago on May 29, 2026 is priced as binary or range-based contracts tied to specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders buy or sell shares at prices between 0 and 100 cents, where the price reflects the implied probability of that outcome occurring. Each contract settles based on the official low temperature recorded for that date. Kalshi's order book displays bid-ask spreads, allowing traders to enter at their preferred price or accept market rates. Volume and liquidity vary by contract, affecting execution speed and slippage for larger positions.

The market resolves on May 30, 2026, after the lowest temperature for May 29, 2026 in Chicago is officially recorded. The outcome is determined by the actual low temperature observed on that date, measured by the designated weather station or official source specified in the contract terms. Once the data is published and verified, the market settles automatically and traders receive payouts based on which outcome bracket or threshold their position matched. Early resolution is not expected unless extraordinary circumstances prevent standard temperature reporting.

Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from the National Weather Service can significantly move odds for Chicago's May 29 low. Tropical systems, polar vortex disruptions, or persistent high-pressure systems weeks in advance may alter trader expectations. Real-time model consensus changes in early May will likely trigger sharp repricing as the event date approaches. Historical temperature records for late May in Chicago also anchor trader priors. Media coverage of unusual spring weather or climate events may shift retail trader participation, adding volatility to the market price independent of meteorological fundamentals.
