Highest temperature in Shanghai on July 6?

Platform comparison

Market context

The real-world event driving this market is the highest air temperature recorded at Shanghai Pudong International Airport on 6 July 2026. In prediction markets, a YES share pays out if the outcome matches the selected condition, while a NO share pays out if it does not. Here, traders are betting on whether the peak temperature will fall into a specific range, with the current crowd-implied probability of 0% for the "YES" outcome suggesting the market expects the temperature to be outside that range.

Historical data frames how to interpret this near-zero probability. July in Shanghai is consistently hot and humid, with average highs between 26–31°C and peaks often reaching 38°C, as seen in July 2025[3]. The warmest day in July typically occurs around 29 July, hitting 32.5°C, while early July days like 3 July are cooler at 24.3°C[4]. Even overnight lows in early July hover near 25–26°C, making a 0% chance for a higher temperature range unusual unless the range is set extremely low[2].

Traders should monitor real-time weather updates from Wunderground and local forecasts for early July heat spikes, as Shanghai frequently experiences sudden temperature surges above 35°C in the first half of the month[8]. Recent climate patterns show shortwave solar energy gradually increasing through July, rising from 5.1 to 5.6 kWh, which can amplify daytime highs[1]. No official government announcements are expected, but traders must watch for sudden shifts in cloud cover or precipitation, as early July still brings significant rainfall that can temporarily suppress temperatures[8].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
