Highest temperature in Shenzhen on August 3?

Platform comparison

Market context

Shenzhen’s afternoon maximum on 3 August is likely to sit in the low- to mid-30s Celsius, with current forecasts pointing to a high around 34°C and a warm overnight floor near 28°C. That keeps the market’s 0% Yes reading on any lower temperature band out of line with the normal August pattern, as multiple climate guides put Shenzhen’s typical August highs around 31–34°C and describe the month as hot, humid and rain-prone.[9][11][17][18]

For framing, comparable late-summer Shenzhen outcomes usually cluster tightly around the seasonal mean rather than breaking sharply above it, so the most useful read is not “hot or cool” but whether cloud, showers or a southerly breeze shave a degree or two off the peak. Timeanddate and other forecast services are showing unsettled, humid conditions with rain chances in the mix, while BBC Weather’s current observations and forecast context keep temperatures in the high 20s to low 30s and humidity elevated, which tends to cap the day’s extreme.[4][7][14]

The main catalyst traders will be watching is the day’s evolving forecast from the airport station, because the market resolves to the highest temperature recorded at Shenzhen Bao'an International Airport and can be sensitive to late-afternoon clears or passing showers. The current leaning appears to rest on weather-model consistency rather than any event calendar: AccuWeather, Weather Channel and other forecast services all show a warm August 3, while the Polymarket listing itself has concentrated interest around the high-20s to low-30s outcomes, with 29°C currently leading and 28–31°C taking most of the implied probability.[6][9][14]

With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.

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.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

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.
