Market Description

This market will resolve according to the total precipitation in mm in Seoul in May, 2026, according to the Korea Meteorological Administration's information for the region/branch of "Seoul". If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. The resolution source for this market will be the Korea Meteorological Administration, specifically the figure for monthly precipitation in mm when the classification is set for "ground", the region/branch is set for "Seoul", the element is set for "precipitation", and the period is set for the month of May at the https://data.kma.go.kr/climate/RankState/selectRankStatisticsDivisionList.do link once the figure is finalized for the whole month of May 2026. If the relevant data is not available by July 7, 2026, 11:59 PM ET, another credible resolution source will be chosen. The resolution source for this market measures precipitation to 1 decimal place (e.g., 1.5), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.

Reason

No override, sports marker, rule, or upstream hint matched. Market is unclassified — the keyword rules need an entry for this topic.

Categories come from a deterministic engine: manual overrides (highest priority) → sports hard markers → event-tag rules → keyword rules → Gamma category hint → default. The engine is versioned in category-overrides.ts; methodology lives at /methodology.
