Highest temperature in Shenzhen on July 24?

Platform comparison

Market context

Polymarket has this contract at **0% YES**, so the market is pricing almost no chance that Shenzhen Bao’an Airport’s recorded high on 24 July 2026 lands in the listed range. The settlement source is straightforward: the final outcome depends on the highest temperature shown for that day on Wunderground for Shenzhen Bao’an International Airport Station, with resolution tied to the day’s maximum reading rather than a forecast or citywide average.

That pricing sits against Shenzhen’s typical July climate, which is hot, humid and rain-prone. July averages are around **32°C** in the daytime, with night lows near **26°C**, and the month is marked by heavy rainfall and frequent showers[1][2][3]. For a temperature market, that matters because cloud cover and rain can suppress extreme highs even when the baseline climate is warm, while clear, humid spells can still push readings towards the low-30s Celsius. In practice, traders on Polymarket are buying and selling USDC on Polygon through conditional tokens, so the price is an on-chain expression of where participants think the airport station’s verified maximum will settle, not a general view on Shenzhen weather.

The main catalysts are the day’s synoptic setup and any late changes in rain band timing, thunderstorm coverage or afternoon sun breaks. Shenzhen’s July weather is often shaped by the East Asian monsoon pattern, so the difference between a wet, clouded day and a brighter one can be enough to move the top reading by a couple of degrees. Traders watching this market should focus on the evolution of local forecast updates and whether showers linger into the warmest hours, because the contract resolves off the airport station’s observed maximum before the 12:00 UTC settlement window ends.

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 PolyGram, which mirrors the Polymarket order book directly.

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

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 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.

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.

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.
