Highest temperature in Taipei on August 16?

Platform comparison

Market context

The market seeks the highest temperature recorded at Taipei Songshan Airport on 16 August 2026, with settlement based on Weather Underground's Daily Observations table rather than summary figures. The current crowd-implied probability of 0% YES suggests traders are pricing in an outcome outside the range specified by this particular market, or that the range itself sits well above typical August conditions in Taipei.

August represents the height of Taipei's summer season, with historical daily highs consistently ranging between 32–35°C at Songshan Airport. The 0% probability indicates the market's temperature threshold sits substantially above this seasonal norm—likely 36°C or higher. Comparable August days at the station show temperatures exceeding 35°C occur occasionally but remain the exception rather than the rule; extreme heat events pushing toward 37–38°C happen roughly once per decade during this month. The consensus pricing reflects scepticism about an unusually severe heat spike coinciding with this specific date.

Traders monitoring this market should track tropical cyclone activity and upper-air pressure patterns developing across the Western Pacific in early August 2026, as these drive Taipei's most extreme heat episodes. The Central Weather Administration's seasonal forecasts, typically released in July, will signal whether atmospheric conditions favour anomalous warming. Additionally, any significant high-pressure system establishing itself over East Asia in mid-August could push temperatures into the upper 35°C range, though breaching the threshold implied by 0% probability would require sustained, intense heat—a relatively rare occurrence for a single day in Taipei's meteorological record.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

UK Frequently Asked Questions

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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%.
