Canonical status
confidence: mediumSource status (Polymarket)
Derived status (Orrery)
Reason
Liquidity is below $1,000 — price discovery is unreliable.
The derived status is computed from the source flags plus the live YES price, so a market trading near a rail can read as PRICE-PINNED while upstream is still active. That isn't the same as resolved.

Market Description
This market will resolve according to the total precipitation in mm in Hong Kong between June 1 and June 30, 2026, according to the Hong Kong Observatory. The resolution source for this market will be the Hong Kong Observatory, specifically the "Total Rainfall (mm)" figure for all days in June 2026 under the "Daily Extract" at the https://www.weather.gov.hk/en/cis/climat.htm link once figures are finalized for the specified range. If the reported data falls exactly between two brackets, this market will resolve to the higher bracket. If the relevant data is not available by September 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.
