Market context
Chongqing faces its peak summer heatwave window as July 17 approaches, with the Jiangbei International Airport Station poised to record the day’s maximum temperature in degrees Celsius. The crowd currently assigns a 0% implied probability to the YES outcome, suggesting consensus that the temperature will fall outside the specific range offered, likely due to expectations of extreme heat exceeding the bracket or unusually cool conditions preventing it. Historically, mid-July in Chongqing routinely sees temperatures surpassing 35°C, often reaching 38–40°C during intense heatwaves, making lower ranges statistically improbable unless a rare monsoon surge or frontal system intervenes.
Traders should monitor the latest 5-day forecast from the China Meteorological Administration and real-time Wunderground updates for the Jiangbei station, as cloud cover and wind shifts from the Yangtze River valley can rapidly alter peak readings. A recent report from the Global Times notes that Chongqing has experienced above-average temperatures this summer due to persistent high-pressure systems, reinforcing the likelihood of extreme heat rather than cool anomalies [1]. The value spot lies in contrarian positions against the 0% consensus if forecast models suddenly indicate a break in the heat dome, though current data favours the underdog scenario of temperatures exceeding the offered range.
Given the settlement window ending 2026-07-17T12:00:00Z, any late-evening temperature spikes on July 16 or early-morning surges on July 17 will directly determine resolution. The favourite remains the high-temperature outcome, with the underdog being the specific range failing to capture the peak. Value may sit in betting against the crowd’s absolute certainty if forecast uncertainty increases overnight.

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 Who Will Win 2026, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
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.
- 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.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 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.
