Highest temperature in Shanghai on July 27?

Platform comparison

Market context

Shanghai’s high temperature on 27 July will be set by the day’s maximum reading at Shanghai Pudong International Airport Station, so the key question is whether the airport’s actual peak lands in the low, mid or upper 30s Celsius. July is normally one of Shanghai’s hottest and stickiest months, with average highs around 32°C, humidity around 76%, and frequent rain, which supports a wide distribution but keeps very high readings plausible[1][5].

The current 0% YES implies the market is pricing the named outcome bands as effectively unreachable, which is hard to square with Shanghai’s normal July climate, where temperatures can exceed 35°C and the late-July period sits inside the city’s typhoon season[5]. Comparable public market pricing on Polymarket has shown top outcomes clustered around 34°C and 35°C for this same event type, suggesting traders have previously treated the mid-30s as the centre of mass rather than an outlier[2]. On accessibility, German GlüStV rules can matter because prediction markets may be treated as gambling products if offered into Germany, while US CFTC jurisdiction can be triggered where event contracts are structured or marketed to US persons; for a “no-KYC up to $1,500” venue, that usually means smaller participation frictions, but not blanket access in every jurisdiction.

The main catalysts are meteorological rather than corporate: forecasts for Shanghai, especially any heat advisory, monsoon rain band, or typhoon-related shift, will matter more than headlines once the day begins. July is also a month with around 12 rainy days and about 135 mm of average rainfall in Shanghai, so cloud cover or showers could suppress the airport’s high even if the broader city feels oppressive[1][5]. Because settlement uses the airport station’s recorded maximum on Wunderground, traders should watch both the timing of the hottest hour and whether storms arrive before the daily peak is logged[1].

FAQ

Is Polymarket legal in my country?

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
