Highest temperature in Shanghai on July 4?

Platform comparison

Market context

The real-world event is the measurement of the peak temperature at Shanghai Pudong International Airport on 4 July 2026, a date deep within the city’s hottest summer month. Historical data confirms that July highs at this station typically climb from 84°F to 88°F (29°C to 31°C), rarely dipping below 75°F (24°C) or exceeding 95°F (35°C) [1]. Summer conditions regularly push temperatures above 30°C, with the most intense sunshine capable of reaching 35°C [7]. Given that the current crowd-implied probability for a specific outcome sits at 0%, the market likely reflects uncertainty about the exact resolution threshold rather than a belief that no heat will occur; July is statistically the peak month for high temperatures in Shanghai, making a cold day highly anomalous.

Traders should monitor immediate weather announcements for July 4, particularly forecasts regarding thunderstorm activity which can suppress peak temperatures. Current short-term models for Shanghai indicate a moderate to high risk of afternoon thunderstorms on 4 July, with temperatures forecast to reach only 32°C (90°F) before rain arrives [3]. The presence of thundery showers, as noted in nearby Hongqiao observations, often limits the daily maximum [4]. A key dependency is the timing of these storms; if heavy rain arrives before midday, the 91°F (33°C) reading observed in recent hourly data at 11:30 am may not be sustained [5]. Traders must watch for official Wunderground updates confirming whether the storm front delays or accelerates, as this directly dictates if the temperature breaches the critical 33°C threshold.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

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.
