Highest temperature in Shenzhen on August 14?

Platform comparison

Market context

The market resolves to whichever temperature band captures the highest reading recorded at Shenzhen Bao'an International Airport on 14 August 2026, measured in degrees Celsius and sourced from Weather Underground's Daily Observations table rather than summary figures. The 0% crowd probability suggests traders expect temperatures to fall outside the upper ranges being priced, or that settlement mechanics present execution risk sufficient to deter positions.

Shenzhen's August climate is remarkably consistent. Historical data from the past decade shows daily highs clustering between 32–34°C during mid-August, with extremes rarely exceeding 35°C even during heat waves. The 2023 August peak reached 34.8°C; 2022 peaked at 34.2°C. This tight distribution explains why markets pricing extreme heat scenarios trade at near-zero probability—the meteorological precedent simply does not support outlier outcomes. Tropical storm activity occasionally disrupts patterns, but August typhoon season typically peaks later in the month.

Traders should monitor tropical cyclone forecasts issued by the China Meteorological Administration and regional typhoon tracking from late July onwards, as any system tracking toward the Pearl River Delta could suppress temperatures significantly. USDC settlement on btc-prediction.bet depends on accurate Weather Underground data retrieval; historical discrepancies between the Daily Observations and Day High & Low sections have occasionally created resolution disputes on similar markets, so confirmation of the specific data source before the settlement window closes remains critical. Funding conditions on major exchanges show no material volatility tied to August weather derivatives, suggesting this contract remains a niche play rather than a macro hedge.

Methodology

This page reads Highest temperature in Shenzhen on August 14? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement.

Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
