Highest temperature in Shanghai on July 1?

Platform comparison

Market context

The underlying event is the daily maximum temperature recorded at Shanghai Pudong International Airport on 1 July 2026, with recent ensemble forecasts indicating daytime peaks near 27–28°C[1][2]. Historical data from the same station shows July as the hottest month, with average highs of 88°F (31.1°C) and daily peaks rarely exceeding 95°F (35°C)[5][7]. While Shanghai saw a preliminary record of 40.9°C at the Xujiahui station in recent years, the airport station typically records lower extremes due to its coastal location[3][9]. The current 0% YES probability for the market likely reflects a misalignment between the crowd’s expectation of a specific threshold and the forecasted 26–27°C range, where 26°C holds a 77% market-implied chance[1][2].

Traders should monitor the official Wunderground release for the airport station on 1 July, as resolution depends solely on this source[3]. Key catalysts include the latest heatwave announcements from China’s National Meteorological Centre, which recently confirmed July as the country’s hottest month on record since 1961[8]. Regulatory accessibility remains a factor: under German GlüStV rules, platforms must verify user identity for transactions exceeding €1,500, while US CFTC reach extends to similar thresholds for non-KYC participation. For this market, the “no-KYC up to $1,500” clause allows traders to access positions without identity verification, provided stakes stay within this limit, enhancing liquidity for smaller participants[1].

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
