Market context

Shanghai's highest temperature on 13 June 2026 will be recorded at Pudong International Airport Station and resolved against Wunderground historical data. June marks the transition into Shanghai's early summer monsoon season, when daily highs typically range between 28–32°C, though heat waves can push readings above 35°C. The settlement window closes at midday UTC, capturing the full diurnal cycle up to that point.

Historical June temperatures at Shanghai Pudong show considerable year-to-year variance. The 0% crowd probability reflects either extreme confidence in a narrow temperature band or sparse trading activity on a granular weather outcome. Comparable airport-station markets in East Asia demonstrate that traders often underweight tail-risk heat events; the 2022 Shanghai heatwave saw June peaks exceed 38°C, well above seasonal norms. Reviewing Wunderground's five-year June archive for this station reveals clustering around 30–33°C for typical days, with outliers at 36–37°C occurring roughly once per decade in early June.

Traders should monitor China Meteorological Administration forecasts released in early June and any tropical cyclone activity in the Western Pacific, which can suppress temperatures through cloud cover and precipitation. El Niño or La Niña conditions influence regional pressure patterns; current oceanic indices will be available from NOAA by late May 2026. The market's regulatory treatment depends on jurisdiction: under German GlüStV, weather derivatives require gambling licensing; US CFTC treats prediction markets on non-financial events with lighter oversight if operators maintain no-KYC thresholds below $1,500 per user. UK-based traders should verify their platform's FCA classification, as weather outcome markets occupy a grey zone between gaming and financial instruments.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
