Highest temperature in Shenzhen on July 7?

Platform comparison

Market context

The underlying event is the peak daytime temperature recorded at Shenzhen Bao’an International Airport on 7 July 2026, measured in degrees Celsius. Historical data confirms July is Shenzhen’s hottest month, with average highs near 32°C (89°F) and peaks often reaching 33–34°C [2][8]. Given that the current crowd-implied probability for “YES” (likely a lower temperature range) sits at 0%, this aligns with climatic norms: temperatures below 25°C in early July are exceptionally rare, as overnight lows typically stay above 26°C and daytime highs rarely dip below 28°C [2][6]. Programmatic traders would treat this as a near-certainty for higher ranges, using Wunderground’s historical daily max as the definitive settlement source [1].

Key catalysts include real-time weather updates from Wunderground and any sudden shifts in regional conditions, such as typhoon activity or heavy rainfall, which could suppress temperatures. Recent forecasts for early July show maximums around 31–32°C with light winds, reinforcing the expectation of high temperatures [5][7]. Traders monitoring this market programmatically should integrate live data feeds from Wunderground’s Shenzhen Bao’an station, cross-referencing with NOAA’s time-series charts for validation [1][5]. No major weather announcements have altered the baseline forecast yet, but typhoon season remains active through August, making sudden deviations possible [8]. The settlement window closes at 12:00 UTC on 7 July 2026, so final data must be captured before that deadline.

FAQ

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 Polymarket Review UK 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.
