Predicting the exact daily minimum temperature of a specific city is somewhat niche and random to the general public, though it is a relatively common fixture within specialized prediction market weather categories.

Between 11:48 and 16:08 on May 10, 2026, the price of the 24°C option plummeted from 49c to less than 1c, while the 22°C option surged from 7c to 44.5c. The 23°C option also experienced volatility, falling from a high of 74.5c to 53c. The reason is that as the actual date of May 11 approaches in Hong Kong time, the latest nighttime cooling observations or updated observatory forecasts indicate that the minimum temperature will be significantly lower than the previously expected 24°C, most likely falling at 22°C or 23°C. Over the past 3 days prior, the price fluctuations for all options had been relatively stable, with no dramatic changes exceeding 10 cents.
