Movers

March 20, 2026 - March 21, 2026, the price of the 15°C option surged from ~7.5c to 26c, having touched higher levels earlier, as the arrival of the event date brought realization of cooler, rainy weather conditions, significantly boosting the probability of this lower temperature bracket. On March 20, 2026, the price of the 16°C option fell from a high of 47c to around 34c, as market consensus fractured, with capital flowing into both the cooler 15°C and the warmer 17°C options, diluting the certainty premium of this middle ground.

Divergence

Significant divergence exists. The prediction market currently prices 17°C as the favorite (~37.5%), which contradicts mainstream meteorological data (AccuWeather/Google forecasting highs of 15-16°C) and real-time observations (cloudy/rainy afternoon with temps hovering around 14-15°C). The market appears to be pricing in a late-day warm spike not supported by forecasts, or simply suffering from lag.
