Highest temperature in Shenzhen on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine this market's outcome. The crowd currently assigns zero probability to any outcome occurring, a statistical impossibility that reflects either extreme confidence in a particular range or minimal trading activity. Resolution depends on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from official highs.

Shenzhen's August climate sits firmly within its hottest season, with historical daily maxima typically ranging between 32–35°C. The city experiences consistent tropical conditions during mid-August, driven by the East Asian summer monsoon and proximity to the South China Sea. Extreme heat events exceeding 37°C occur occasionally but remain statistical outliers; the 0% probability assigned suggests traders expect outcomes clustering in the 33–36°C bands rather than exceptional heat or anomalous cooling.

The settlement window closes at midday UTC on 16 August 2026, creating a narrow observation period. Traders should monitor seasonal forecasts from the China Meteorological Administration and track any tropical cyclone activity in the western Pacific, which could suppress temperatures through cloud cover and precipitation. The specific reliance on Bao'an Airport data—rather than urban stations that may record higher readings—anchors expectations to a coastal, relatively exposed location where sea breezes provide modest temperature moderation compared to inland Shenzhen districts.

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 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.
