Highest temperature in Shenzhen on August 10?

Platform comparison

Market context

The event is the **highest recorded temperature** at Shenzhen Bao'an International Airport on 10 August, with the market resolving from Weather Underground’s **Daily Observations** rather than the summary high/low box. That distinction matters because intraday spikes can differ from the headline forecast or daily summary, and the relevant resolution point is the maximum value captured before the settlement window closes at 12:00 UTC.[5][11]

The current 0% yes price sits against Shenzhen’s late-summer climate, where August averages cluster around **32°C** and recent forecast pages have repeatedly shown highs in the **mid-to-upper 30s Celsius** for 10 August.[3][8][12][14][17][18] Comparable histories from the city show that the day often reaches the low-to-mid 30s Celsius, with occasional hotter readings, so a zero-implied chance suggests the market is pricing in either a very narrow range mismatch or a belief that the observed station reading will land outside the listed bins.[2][7][9][12]

For accessibility, the key regulatory lens is that prediction market availability can depend on where the operator is licensed and how it treats customers under local rules: Germany’s GlüStV framework generally makes retail access and advertising more restrictive than in lightly regulated jurisdictions, while US CFTC reach can matter if a venue is deemed to offer event contracts to US persons.[19][20] If an exchange advertises **“no-KYC up to $1,500”**, that usually means a user may be able to trade or withdraw up to that cumulative threshold without identity verification, but the market can still remain unavailable in some countries or for some counterparties because geo-blocking, sanctions screening, and internal compliance checks can apply before any KYC threshold is reached.[19][20]
