Predicting the exact high temperature on a specific day in a specific city is somewhat niche and not something the general public actively thinks about, though it is a relatively common topic in prediction markets or weather derivatives.

The market title asks for 'Seoul', but the rules explicitly state that resolution relies on the 'Incheon Intl Airport Station (RKSI)'. The airport is coastal and can have a significant temperature difference from downtown Seoul, posing a severe geographic trap for unwary traders. Additionally, it strictly relies on unrevised integer data from Wunderground.

May 1, 2026 - May 2, 2026: The price of the 15°C option surged from 25.5c to 41c, because as the expiration date approached, updated weather forecasts strongly confirmed rainy conditions, concentrating the predicted temperature around 15°C. April 29, 2026 - May 1, 2026: No price movement exceeding 10 cents was observed, indicating that the market pricing for all options remained relatively stable.
