Highest temperature in Chengdu on August 3?

Platform comparison

Market context

Chengdu’s late-summer heat is the underlying event here: the market resolves on the day’s **highest temperature** at Chengdu Shuangliu International Airport Station, not the average or the afternoon forecast. Public August climatology points to a hot, humid pattern, with typical daytime highs around 30–33°C and frequent rain showers, so the settlement question is whether the station prints a genuinely hot peak rather than simply a warm day.[1][2][9][12][14]

The current **0% YES** crowd-implied probability is best read against that seasonal baseline and the resolution method. For a temperature-range market, a zero reading usually means traders are assigning negligible odds to the selected range covering the eventual daily maximum, but that can change quickly if the day trends towards a hotter-than-normal spike; comparable August guidance for Chengdu repeatedly shows highs in the low 30s Celsius, with some sources also flagging occasional 35°C+ outcomes, which makes the exact range and intraday peak more important than the headline forecast.[5][10][11][16]

From a market-access perspective, the legal frame is mainly about where the user sits. In Germany, the GlüStV regime is relevant because it can restrict or shape access to gambling-style products regardless of the underlying weather event, while US persons also face the CFTC’s broad reach where a contract may be treated as a derivative or event-based wager depending on structure and venue; those are regulatory exposure points, not conclusions about this specific market. “No-KYC up to $1,500” generally means a trader can typically transact small amounts with lighter identity checks, which improves accessibility for casual participation but does not remove geo-blocking, account limits, or any jurisdiction-based compliance checks tied to the platform and the user’s location.
