Highest temperature in Shanghai on June 29?

Platform comparison

Market context

The underlying event is the peak daytime heat recorded at Shanghai Pudong International Airport on 29 June 2026, measured in degrees Celsius. Historical data shows June highs at this station typically range between 28°C and 30°C, rarely exceeding 33°C, with average daily highs increasing from 25°C to 29°C as the month progresses[1][5]. The current crowd-implied probability of 0% for a higher temperature range suggests traders expect conditions to remain within standard seasonal bounds, consistent with recent forecasts indicating daily highs of 27°C to 29°C and a 25% risk of thunderstorms that may suppress peak temperatures[2][4].

Traders should monitor real-time weather updates from Wunderground, the official resolution source, particularly for sudden shifts in cloud cover or rainfall intensity that could alter the maximum recorded temperature[1]. A recent 14-day forecast from The Weather Network highlights a 25% risk of thunderstorms on 29 June with light rain expected, which historically correlates with lower peak temperatures compared to clear, sunny days[4]. Additionally, watch for any official announcements from Chinese meteorological authorities regarding extreme heat alerts, as these could signal deviations from the typical 28°C–30°C range and impact settlement outcomes.

Regulatory accessibility for this market is shaped by overlapping frameworks: Germany’s GlüStV imposes strict licensing for prediction markets, while the US CFTC maintains reach over any platform offering contracts to US residents, regardless of location. The “no-KYC up to $1,500” provision allows traders to participate without identity verification for smaller stakes, enhancing accessibility but not exempting platforms from compliance obligations under these regimes. This specific market’s low settlement threshold and weather-based resolution source fall within the scope of non-financial derivative contracts, which may face lighter scrutiny but still require adherence to KYC and anti-money laundering rules where applicable.

FAQ

Is Polymarket legal in my country?

Is there a withdrawal cap?
