Highest temperature in Beijing on July 23?

Platform comparison

Market context

Beijing’s highest temperature for 23 July is being set by the airport station reading, and the market is effectively wagering on whether heat is checked by cloud, rain or a clean run of sunshine. With the crowd currently showing **0% YES**, the pricing looks detached from the day’s actual weather setup and may be reflecting uncertainty over the exact settlement bucket rather than a broad view on the temperature itself.[1]

For context, Beijing in July is typically hot and humid, with average temperatures often described as running from **23°C to 31°C**, while the month is also among the wetter parts of the year, with rainfall averaging about **185 mm**.[2] That mix matters because the day’s high can be capped quickly if convection or afternoon showers arrive, but it can also push into the upper 20s if skies stay clearer for long enough. The market’s own spread around **28–31°C** suggests traders are leaning on short-term forecast variation rather than a structural climate signal.[1]

The main catalyst to watch is the live forecast and any late changes in cloud cover or rain timing for Beijing Capital International Airport, since that is what will most directly shape the final high. The market description also makes clear that the decisive data point is the airport station’s daily history page on Wunderground, and revisions remain possible until the first datapoint for the following day is published.[1] That means traders will likely focus on late morning and afternoon weather updates, with the real risk centred on whether the airport reaches the upper 20s before any precipitation or thicker cloud suppresses the peak.[1][2]

FAQ

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
