03.17 23:52 UpdatedFair Value Reasoning:
Consolidating forecasts from Google Weather and Tiempo3, the high temperature for Milan on March 18 is primarily targeted at 13°C. Major Italian meteorological sources (Meteo.it/iLMeteo) have issued alerts for 'colder air' (aria più fredda) and a return of 'winter conditions' starting March 18, accompanied by rain, which will suppress temperatures. Given that March 17 was approx 15°C, the incoming cold front logically suggests a drop to the 13°C-14°C range. The market is heavily overpricing 16°C+ (32.5c) and 15°C (30.5c), contradicting the 'cooling' fundamental, leaving 13°C (11c) significantly undervalued.

Movers
From 07:25 to 23:40 on March 17, 2026, the price of the '15°C' option plummeted from 59.5c to 30.5c, and '16°C or higher' dropped from 52.5c to 32.5c. This was due to a correction from an extremely irrational morning session (where the sum of implied probabilities neared 200c) as the forecast for colder air (dropping to 13-14°C) became clearer, forcing a sell-off in the high-temperature options.
Divergence
Significant divergence exists. Polymarket prices imply a >60% probability of temperatures being 15°C or higher, likely relying on older warm-ridge model data. However, the latest real-time forecasts (Google, Meteo.it) explicitly predict 'colder air' and rain for Wednesday, targeting a high of around 13°C. Market pricing is severely lagging behind the updated 'cooling' reality.
