This market tracks whether Paris will experience a maximum daily temperature of exactly 12°C on April 20, 2026. The city's weather in mid-to-late April typically shows spring variability, with highs ranging from 10°C to 16°C depending on Atlantic pressure systems and local conditions. At 0% odds, the market strongly suggests traders view a precisely 12°C high as extremely unlikely—the day will likely be either warmer or cooler than this specific threshold. Weather prediction markets like this one resolve using official data from Météo-France, France's national weather service, which records the daily maximum temperature at Paris observation stations. The precision required here—matching exactly 12°C rather than a temperature range—makes such outcomes rare, explaining why the market assigns near-zero probability to YES. As the resolution date approaches, forecasters will refine their predictions, but the exactness requirement keeps market sentiment anchored at minimal YES probability. Traders typically use such daily weather markets to hedge weather-dependent activities or for pure weather forecasting interest.
