AI Insights:
8 hours ago UpdatedFair Value Reasoning:
Synthesizing latest forecasts from AccuWeather (17°C/63°F), Met Office (17°C), and Google Weather (16°C/61°F), the weather in Paris on March 21 points decisively towards the 16°C to 17°C range. Wunderground, the resolution source, typically aligns with airport (LFPG) readings, which often trend warmer under the forecasted sunny conditions. The market is currently overpricing '15°C' as the favorite (~27%), contradicting the warming trend seen in major meteorological models for the weekend. Fair value is heavily skewed towards 17°C and 16°C, with '18°C or higher' representing an undervalued upside risk given the potential for solar heating to push temps slightly above forecasts.

Movers
2026-03-18 00:55 - 2026-03-18 02:00, the price of 13°C crashed from 22c to 7.5c, while 14°C dropped from 26c to 22c (continuing to 14.5c later). This volatility likely stems from a correction in early meteorological models removing a cold front prediction, or smart money correcting mispricing on cooler options, shifting consensus back to the warmer 16-17°C range.
2026-03-17 17:20 - 2026-03-18 02:00, the price of 11°C plummeted from 16c to 4c, driven by the same elimination of extreme cold scenarios as the date approaches.
Divergence
Significant divergence. Polymarket currently prices '15°C' as the most likely outcome (~27c), whereas major meteorological sources including AccuWeather and Met Office forecast a high of 17°C, with Google Weather at 16°C. The market pricing lags behind the latest warming forecasts, undervaluing the probability of 17°C and 18°C+.
