Highest temperature in Taipei on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Taipei Songshan Airport Station will determine which Celsius range resolves YES on this market. The 0% crowd probability reflects either extreme confidence in a specific outcome or sparse liquidity; with settlement nearly two years away, the contract pricing likely reflects minimal trading activity rather than a consensus forecast. Polymarket's USDC settlement on Polygon means positions are held as conditional tokens until the Weather Underground Daily Observations table is finalised at 12:00 UTC on the settlement date.

Taipei's August temperatures have historically clustered between 32–36°C, with occasional peaks above 37°C during heat waves. The city's subtropical monsoon climate produces consistent summer highs, though extreme heat events—exceeding 38°C—occur roughly once per decade. Comparable August days at Songshan Airport show the range typically settles in the 33–35°C band, making outlier outcomes (sub-32°C or above 38°C) statistically less frequent but not implausible given climate variability and seasonal anomalies.

Traders should monitor tropical cyclone forecasts issued by the Central Weather Administration Taiwan in the weeks preceding August 2026, as typhoons can suppress temperatures significantly. El Niño or La Niña patterns announced by NOAA in early 2026 will influence seasonal heat intensity across East Asia. The specific resolution methodology—using Weather Underground's Daily Observations table rather than the Day High & Low summary—creates a technical dependency; discrepancies between the two sources have occasionally occurred, making source verification critical for settlement disputes.

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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%.
