This Polymarket event asks what the lowest temperature recorded in Hong Kong will be on October 28, 2026. The contract resolves to the temperature range that contains the Hong Kong Observatory's lowest recorded temperature for that date, measured in degrees Celsius [1]. Each market in the event is a separate range, such as a single whole-degree value or an open-ended range at either extreme, and the market for the matching range settles on that outcome [1]. The resolution source is the "Absolute Daily Min" figure for the specified date in the Hong Kong Observatory's "Daily Extract" [1]. The rules say this figure is used once the information is finalized in that extract [1]. Temperatures are measured to one decimal place, so a reading such as 9.1 degrees Celsius is the level of precision used when settling a market [1]. The rules set two timing conditions. A market resolves once data for the date has been published on the resolution source, or by 11:59 PM ET on the seventh day after the observation date, whichever comes first [1]. If no data for the observation date is available by that later deadline, the market resolves to the lowest bracket [1]. The listed end time for the event is 2026-10-28T12:00:00.000Z [1]. This is a date stated in the contract rules and does not, by itself, confirm when the Observatory will publish the figure. The rules also address revisions. The Observatory's initial publication for the period is the revisions cutoff, and later revisions are not considered for resolution [1]. The main exception concerns a clearly erroneous print caused by technical or operational error or by unauthorized interference. In that case the market may remain open for up to seven calendar days (ET) from the original release so the Observatory can publish a correction, and a corrected value published within that window can be used [1]. If no correction appears, Polymarket may issue a Clarification to decide whether the original value can be used or whether other action is needed [1]. The price shown for each range is a snapshot from the provider's data at the time it was observed, not an executable quote. The saved event data was observed at 2026-10-26T06:00:06.440Z and retrieved at 2026-10-26T08:28:23.788Z [1]. At the time of that snapshot the event was listed as active [1].
