Highest temperature in Shanghai on June 29?

Platform comparison

Market context

The underlying event is the highest temperature recorded at Shanghai Pudong International Airport on 29 June 2026, a date that historically falls within the city’s hot, humid rainy season. Current crowd-implied probability of 0% for any temperature range above 35°C suggests traders expect conditions to remain below extreme heat thresholds, likely influenced by anticipated cloud cover or precipitation.

Historical data shows June highs at Pudong typically range from 25–30°C on cloudy or rainy days, rarely exceeding 35°C unless under intense, clear-sky conditions [1][4][6]. In past years, temperatures above 35°C have occurred only during the most sunny spells, with daily highs increasing by 7°F across the month but seldom breaching 92°F [1]. This pattern frames the 0% probability as consistent with seasonal norms rather than an outlier.

Traders should monitor upcoming weather forecasts for thunderstorm risk, which is currently cited at 25% for 29 June, alongside scheduled declarations from local climate authorities regarding heat advisories [5]. A key catalyst is the potential for a sudden shift in cloud cover or rainfall, which could suppress temperatures below 30°C. Recent news from The Weather Network highlights persistent thunderstorm risks and light rain expected on the day, reinforcing the market’s lean toward moderate temperatures [5]. No major political debates or campaign-finance disclosures are tied to this weather event, making meteorological data the primary driver.

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.

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.

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.

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.
