Highest temperature in Chongqing on July 27?

Platform comparison

Market context

Chongqing’s late-July heat is normally strong enough that the day’s top reading often lands in the mid-to-high 30s Celsius, with July averages around 33°C and a rainy, humid monsoon pattern rather than a dry heat regime.[1][2] For a market that settles on the highest temperature at Chongqing Jiangbei International Airport Station, the practical question is whether the day peaks in the 38–40°C band or cools enough under cloud and rain to stay below that range.[1][4]

The current 0% YES price should be read against the city’s seasonal profile, not as a literal forecast of impossibility. July is described as Chongqing’s hottest and most humid month, and the rainy season runs from May to September, with rainfall accounting for about 70% of annual total; that combination creates swings between oppressive heat and short-lived storm relief, which is exactly the sort of setup that matters when traders model a single daily maximum programmatically.[2][5] The market’s own live ladder currently puts 39°C and 38°C well ahead, which is consistent with those climate norms rather than with a low cap outcome.[3]

For catalyst tracking, the useful inputs are the airport station’s hourly progression, convective rain timing, and any shift in cloud cover or monsoon flow before local afternoon peak heating. A bot or copy-trading workflow would usually watch the Wunderground history page for intra-day updates, compare the realised max against nearby temperature bands, and avoid over-weighting an early-morning reading because the settlement source is the day’s highest value, not the first observed value.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Bot UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
