Highest temperature in Shanghai on July 5?

Platform comparison

Market context

Shanghai Pudong International Airport is set to record its peak July temperature on 5 July 2026, a critical real-world event that determines the outcome of this prediction market. Historical data shows daily highs in July typically climb from 84°F to 88°F, rarely dipping below 75°F or exceeding 95°F[1]. The cloudiest month of the year is July, with skies overcast or mostly cloudy 67% of the time, which often moderates extreme heat spikes[4]. Summer climates regularly exceed 30°C (86°F), reaching 35°C (95°F) during the most sunny conditions[6]. Given these comparable cases, the current 0% crowd-implied probability for the highest temperature range appears inconsistent with the typical thermal behaviour of the region, suggesting a potential mispricing by traders who may be overlooking baseline climatic patterns.

Traders should monitor immediate weather announcements and forecast updates, particularly regarding thundery showers and humidity levels that could suppress peak temperatures. AccuWeather forecasts cloudy, humid conditions with a potential afternoon thunderstorm for 5 July, with a high of 83°F, followed by a hotter 93°F on 6 July with scattered thunderstorms[8]. The BBC notes thundery showers and a gentle breeze for Hongqiao Airport on the same date, with a high of 29°C (84°F), indicating similar atmospheric pressure across the city[3]. These dependencies mean that sudden shifts in precipitation or wind speed could alter the final recorded maximum, making real-time radar data from Wunderground essential for accurate position management before the settlement window closes on 2026-07-05T12:00:00Z.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
