Highest temperature in Shanghai on July 17?

Platform comparison

Market context

Shanghai faces its peak summer heat today, with the highest temperature at Pudong International Airport determining the outcome of a weather contract settling at noon UTC. The market currently prices the YES outcome at 0%, implying the crowd expects the temperature to fall outside the specific range offered, likely due to an anticipated cool spell or a mismatch between the range and historical July highs.

Historical data from July 2023 and 2024 shows Shanghai’s daily maximums at Pudong typically range between 32°C and 37°C during mid-July, with extreme heatwaves occasionally pushing readings above 38°C. The 0% probability suggests traders believe the specific range in this contract is either too low to capture a standard July high or too high to be reached without a record-breaking heat event, which current forecasts do not support.

Traders should monitor the hourly updates on Wunderground for the Pudong station, as the settlement relies exclusively on this source’s recorded maximum for 17 July 2026. While no specific weather announcements are scheduled for today, the broader East Asian monsoon pattern and any sudden cloud cover or rain fronts moving from the Yangtze River delta could suppress temperatures below the contract’s threshold. The on-chain mechanics on Polygon, using USDC and conditional tokens, ensure the resolution is automatic once Wunderground publishes the final daily figure.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
