Highest temperature in Shanghai on July 15?

Platform comparison

Market context

Shanghai faces a day of heavy cloud cover and rain at Pudong International Airport, with maximum temperatures forecast near 35°C and a 90% chance of precipitation. This wet, cloudy pattern directly suppresses the likelihood of extreme heat, explaining why the crowd-implied probability for any outcome above 35°C sits at 0% for the YES side of higher ranges. The market currently leans heavily on 38°C as the frontrunner at 49%, yet today’s immediate weather conditions contradict that high-heat expectation, suggesting the 0% probability reflects a rational assessment of current atmospheric barriers rather than a market error [1][2].

Historical July data for Shanghai typically sees temperatures climbing to 37–39°C under clear skies, but the presence of heavy rain and broken clouds at 2000ft drastically limits solar heating. Comparable cases from recent years show that when precipitation exceeds 0.8 inches and cloud cover persists, peak temperatures rarely breach 36°C, aligning with the current 35°C maximum forecast [2][3]. Traders should watch the Wunderground daily history for Pudong Airport as the settlement source, noting that any sudden shift to clear skies before 12:00 UTC could alter the outcome, though current forecasts indicate no such shift [1]. No political catalysts or campaign disclosures influence this weather event; the sole dependency remains the real-time meteorological data recorded at the station.

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 Trump Prediction 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.

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.
