Precipitation in Hong Kong in May?

Precipitation in Hong Kong in May? is a prediction market forecasting the total rainfall in Hong Kong during May 1–31, 2026, using the Hong Kong Observatory’s final “Total Rainfall (mm)” figure. This event asks traders to estimate how much precipitation the city will record over the month, with resolution based on the Observatory’s Daily Extract once the figures are finalized. Because the market is tied to a specific scientific data source, it reflects a weather and science forecast rather than a political outcome, even though it is listed under the geopolitics category. The market will resolve according to the reported rainfall total to one decimal place, and if the result falls exactly between two brackets, it resolves to the higher bracket. If the data is still unavailable by July 7, 2026, another credible source may be used. Current market probability is around 5%, suggesting traders see this outcome as relatively unlikely, though not impossible. For those following prediction market odds and market sentiment, this is a straightforward event prediction centered on Hong Kong weather data.
