Polymarket Weather Markets: Trade Temperature Odds With a Forecast Edge
Polymarket lists live weather markets on daily city temperatures and other climate outcomes. Each one is a yes/no contract whose price moves like a probability — a share at 72¢ means the market is pricing roughly a 72% chance. Kumo Edge reads those markets through the lens of real forecast models, so you can see when the odds drift away from what the weather is actually likely to do.
How Polymarket weather odds work
Buy “Yes” or “No” shares on an outcome such as a city's daily high temperature falling in a given range. As new forecast data arrives, fair value shifts — and the market price doesn't always keep up. That lag between the forecast and the posted odds is the opportunity Kumo Edge is built to surface.
What Kumo Edge gives Polymarket traders
- A model-based probability for each temperature outcome, next to the live Polymarket price.
- Multi-model ensemble forecasts — GFS, ECMWF, HRRR and NAM — distilled into one clear read.
- The same forecast engine used for Kalshi, so you can compare both venues from one place.
Polymarket vs. Kalshi weather markets
Both let you trade temperature outcomes, but they differ in structure, settlement and access. Kumo Edge covers both from one place, so you can act on whichever venue offers the better price. See our Kalshi weather trading page for the Kalshi side.
