Market context
Chongqing’s July heat is notoriously severe, with daytime highs typically climbing between 32°C and 37°C, while the city’s all-time record stands at 43.2°C. Historically, daily peaks in July rarely exceed 39°C, yet the overwhelming majority of years see temperatures clearing 30°C. The current crowd-implied probability of 0% YES for the highest temperature on 2 July 2026 appears starkly disconnected from this baseline, suggesting the market may be mispricing the likelihood of extreme heat or confusing the temperature range threshold.
Polymarket prices this contract today on the Polygon network using USDC, where conditional tokens reflect the binary outcome of whether the temperature falls within a specific range. Traders should monitor the upcoming weather forecasts from Wunderground for the Chongqing Jiangbei International Airport Station, as sudden shifts in humidity or cloud cover could alter the peak temperature. A recent Reuters report highlights that Chongqing residents are already seeking shelter from heatwaves hitting China’s southwest, indicating that extreme conditions are not merely theoretical but actively impacting the region.
The catalysts for this market include daily weather bulletins and any official announcements regarding heatwave warnings, which could signal a spike in temperatures. July has the highest number of rain days in Chongqing, averaging 20.2 days, so unexpected rainfall could suppress the peak temperature. However, given the city’s historical tendency to hover above 30°C in July, the 0% probability seems overly cautious. Traders must weigh the on-chain mechanics against the real-world data, ensuring their USDC positions align with the factual likelihood of extreme heat in Chongqing.

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.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Qué Es trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
