Exotics

This is a typical weather prediction market. While not as universally common as 'will it rain tomorrow', it is not unfamiliar to those interested in regional weather derivatives or climate. It is more niche than mainstream political/financial forecasting but belongs to a mature category.

Movers

March 22, 2026 - March 23, 2026, the price of '32°C or higher' crashed from 50c to 18.5c, as approaching forecast dates solidified models (AccuWeather, Google) around a mild 27-28°C range, causing early speculative bets on extreme heat to unwind. March 22, 2026 - March 23, 2026, the price of '23°C' dropped from 11.5c to 2.3c, as forecasts confirmed temperatures would not be anomalously low, eliminating the extreme cold outlier.

Divergence

Significant divergence exists. Mainstream meteorological models (Google, AccuWeather, Ventusky) consistently forecast a high of 27°C or 28°C. However, current prediction market pricing implies a >60% probability of temperatures being 30°C or higher (30°C: 24c, 31°C: 19.5c, 32°+: 18.5c). This pricing is completely disconnected from fundamental data, suggesting market participants have not updated to the latest forecasts or hold an irrational bias toward heat.
