Highest temperature in Chengdu on July 23?

Platform comparison

Market context

Chengdu’s reported maximum for the day will be set by the highest reading at Chengdu Shuangliu International Airport Station, so the market is effectively pricing the afternoon heat profile rather than the morning start. With the settlement window ending at noon UTC, traders are leaning on the likelihood that the day’s peak in local time will already have occurred or be imminent, making the final hours of the diurnal cycle decisive rather than any late-night movement.

The current 0% YES price implies the crowd sees the target temperature band as highly unlikely, which is more consistent with a cool-day outcome than with a marginal overshoot into the next bracket. In weather markets, tiny shifts in the forecast maximum often matter more than broader city averages, because airport stations can run a degree or two away from the urban core depending on cloud cover, wind, and rainfall timing. Comparable hot-season markets typically only move once short-range forecasts begin tightening on the exact noon-to-evening peak, rather than on generic seasonal expectations.

The key catalyst is the local short-range forecast and any updated guidance from the airport station’s daily history page, since the market resolves to the recorded maximum rather than an official public forecast. Traders should watch for changes in the expected afternoon high, especially if cloud, showers, or a heat advisory alters the peak temperature band before the day closes. For context, news and forecast aggregators usually shift the most when a late change in cloud cover or precipitation timing becomes visible in the near-term model run.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.
