How Kalshi weather markets work
Weather is one of Kalshi's more distinctive categories: you can trade on whether a city hits a temperature, whether it rains, or how a storm season plays out. Because weather is measured by official instruments, these markets have unusually clean resolution.
Here is how they work.
Weather as a Yes/No contract
A weather market is the same event contract as anything else on Kalshi: a precise Yes/No question, such as whether a specific city's high temperature will exceed a threshold on a given day. It pays $1 if correct and $0 if not, and the price is the market's implied probability.
They settle on official readings
Weather markets resolve against an official data source, such as a designated weather station's recorded measurement. The resolution rules specify exactly which station, which measurement, and over what window. That precision is what makes weather markets relatively clean: the outcome is a published number, not a judgment call.
Read the fine print
The details decide the trade. Two markets about the same city can differ on the exact station, the rounding, or the cutoff time. Before trading, confirm the precise threshold and the official source in the resolution rules, because weather outcomes can hinge on a single degree or a measurement taken at a particular site.
Why traders like them
Weather markets reward people who follow forecasts and understand the data, and they are uncorrelated with the news cycles that drive politics or economics. Liquidity varies, so as always, check the order book depth before sizing a position.
