Fair Value Reasoning:

Market sentiment has undergone a drastic correction. Previous bets on 34-35°C heat, based on general 'dry phase' expectations, have collapsed, likely due to specific 3-day forecasts indicating cloud cover or rain, reducing the chance of extreme heat. Pricing has reverted to the climatological mean for Singapore in March (32-33°C). The earlier pricing anomaly on '25°C or below' (trading at 25 cents) has fully corrected to near zero. Fair value is now heavily concentrated on 32°C and 33°C given tropical volatility.

Movers

From March 17 to March 18, 2026, the price of '35°C or higher' crashed from 25.5c to 1.6c, while '32°C' and '33°C' surged from around 17c to over 30c. The reason is an update in short-term weather forecasts which invalidated the previous extreme heat expectations, shifting the outlook back to normal ranges. Between 10:30 and 12:40 on March 17, 2026, the price of '25°C or below' collapsed from an anomalous 25c to 1.1c. The reason was a correction of a gross mispricing caused by irrational flows or illiquidity; prices reverted to common sense as liquidity normalized.

Divergence

Significant divergence exists. The previous analysis cited the Meteorological Service Singapore (MSS) outlook for the second half of March predicting highs between 34-35°C. However, current prediction market pricing (favoring 32-33°C) reflects real-time, short-term weather models suggests cooler conditions than the semi-monthly outlook. The market is effectively 'correcting' the broader official forecast.
