Highest temperature in Beijing on July 10?

Platform comparison

Market context

The real-world event hinges on the highest temperature recorded at Beijing Capital International Airport on 10 July 2026, with the crowd assigning a 99% probability that the figure will stay within a specific range. Historical data frames this near-certainty: July is Beijing’s hottest month, with daily highs averaging 31°C (88°F) and rarely dropping below 26°C (78°F)[4]. In 2023, temperatures peaked at 40°C (104°F), while the all-time record of 41.9°C (107°F) was set on 24 July 1999[1][3]. Recent trends show China experienced its hottest July on record in 2024, with national averages breaking historical benchmarks[10].

Traders should monitor official heatwave advisories and meteorological bulletins, as authorities have previously urged people to limit outdoor exposure during extreme heat[3]. The settlement depends entirely on Wunderground’s official daily high for the airport station, with resolution fixed at noon UTC on 10 July. Thin trading volume and forecast risk remain key variables, as similar markets have seen volatility despite high implied probabilities[2][9].

Regulatory access is shaped by German GlüStV rules on prediction markets, US CFTC reach over derivatives, and the “no-KYC up to $1,500” threshold that permits anonymous participation for smaller bets. This specific market’s accessibility is thus broad for retail traders under the threshold, though larger positions may trigger compliance checks. Facts remain clear: the event is weather-driven, the probability is high, and the resolution source is definitive.
