Highest temperature in Taipei on August 8?

Platform comparison

Market context

Polymarket is pricing this Taipei temperature contract at **0% YES** right now, which means the market is effectively assigning no chance that the Taipei Songshan Airport Station’s highest **Daily Observations** temperature on 8 August lands in the winning band. Because the market settles in **USDC** on **Polygon** through conditional tokens, the practical question for a user is not whether Taipei is hot in general, but whether the station’s single-day maximum prints inside the exact range that resolves the market.

For context, Taipei can still produce very sharp August spikes even in a humid, rainy season. Historical examples show that the city has reached **39.3°C** on 8 August 2013, and another August heat event produced **38.5°C** in 2017, both far above ordinary seasonal levels.[3][4] At the same time, broader August climate references put Taipei’s typical highs around the low-30s Celsius, with forecasts for this month generally clustering in the high-20s to low-30s overnight and around **30–34°C** by day.[1][2][10][15]

The main catalyst to watch is the live Weather Underground daily observation feed for **Taipei Songshan Airport Station**, because the market explicitly resolves from the highest reading in that table, not the summary high/low box.[8] Near-term forecast pages point to showers, thunderstorms and heavy rain in Taipei on 8 August, which would usually cap the upside and make an extreme heat print less likely, but short-lived clear spells can still matter if they coincide with the day’s peak.[11][17] A trader using Polymarket should therefore focus on the intraday station observations as they publish, because the first reading for the following date also gates final resolution timing.[8]

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 Kalshi UK, which mirrors the Polymarket order book directly.

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%.
