While weather derivatives exist in professional finance, betting on a specific city's exact daily temperature in a retail prediction market is somewhat niche and represents a moderately exotic novelty market.

Morning to noon April 16, 2026, the price for '33°C' surged from 42.5c to 99.85c, while '34°C or higher' plummeted from 21.25c to 0.05c. This was caused by the progression of the day past peak heating hours in Singapore, locking in the actual recorded maximum temperature at exactly 33°C and eliminating the possibility of hitting 34°C. Late April 15 to early April 16, 2026, the price for '33°C' surged from 20.5c to 42.5c, and '34°C or higher' jumped from 4.8c to 21.25c, while lower brackets plummeted to effectively 0c. This was caused by the transition into the daytime of April 16 in Singapore; real-time observations and short-term forecasts indicated significantly hotter temperatures than initially expected, prompting traders to shift capital rapidly toward higher temperature brackets.
