Highest temperature in Shanghai on July 2?

Platform comparison

Market context

The underlying event is the peak daytime heat recorded at Shanghai Pudong International Airport on 2 July 2026, a date historically prone to extreme summer temperatures. Current crowd-implied probability of 0% for a specific temperature range suggests the market expects the reading to fall outside that bracket, likely due to the region’s consistent July heat patterns.

Historically, Shanghai in July averages daily highs between 30°C and 35°C, with the hottest day typically occurring around 29 July at 32.5°C [5]. Past data from June 2026 shows highs ranging from 78°F to 93°F (25.6°C to 33.9°C) [1], while July 2026 forecasts indicate daily highs between 80°F and 93°F (26.7°C to 33.9°C) [4]. These comparable cases frame the 0% probability as a mispricing, given the airport’s reliable exposure to high summer temperatures.

Traders should monitor Wunderground’s real-time updates for the Pudong station, as well as any sudden shifts in regional weather advisories or monsoon activity that could alter peak temperatures [7]. Recent news notes Shanghai Pudong Airport handled over 15 million passenger trips in the first five months of 2026, indicating stable operational conditions that support consistent weather data collection [6]. The market leans on the catalyst of uninterrupted temperature logging, with no scheduled political debates or campaign-finance disclosures expected to interfere with the settlement window.

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.
