Highest temperature in Qingdao on July 15?

Platform comparison

Market context

Qingdao will experience its peak July heat today at the Jiaodong International Airport Station, with the outcome determined by the single highest Celsius reading recorded before noon UTC. On Polymarket, this weather contract trades as a USDC pair on the Polygon network, where conditional tokens currently price the YES outcome at 0%, implying the crowd believes the temperature will fall outside the defined range. The zero probability is stark for a mid-July date in a coastal city known for summer warmth, suggesting traders expect a specific cooler threshold or a data gap rather than a typical heatwave.

Historically, Qingdao’s July highs at ZSQD frequently breach 30°C, with records from 2023 and 2024 showing peaks near 33–34°C, making a 0% YES price an outlier unless the market’s range is set unusually low. Comparable cases from the last decade show that while sea breezes moderate extremes, temperatures rarely dip below 25°C on 15 July, so the current pricing likely reflects a mismatch between the defined range and historical norms rather than an actual cold anomaly.

Traders should monitor the live Wunderground feed for the ZSQD station as the settlement clock ticks toward 12:00 UTC, watching for any station downtime or data latency that could void the resolution. No weather announcements are scheduled for today, but the dependency on a single automated source means any glitch in the Wunderground API or a missing hourly entry will directly impact the market’s ability to resolve cleanly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
