Highest temperature in Taipei on August 6?

Platform comparison

Market context

Polymarket has this contract priced at **0% YES** today, so the crowd is not assigning any meaningful chance to an outcome in the listed temperature bands at present. On-chain, that price reflects the market for conditional tokens settled in **USDC** on **Polygon**, with each outcome share paying out only if the Taipei Songshan Airport Station’s highest temperature on 6 August 2026 lands in the matching range.

The broader weather context does not point to a cold day: Taipei’s August climate is typically very hot and humid, with average highs around **33–34°C**, and several guides put peak daytime readings near **35–36°C** or higher in late summer.[4][5][6][14] That makes the market’s 0% print notable rather than informative about the actual forecast; traders usually read it as a thin or inactive book, not a claim that extreme heat is impossible. For comparison, Polymarket’s own market page shows the live crowd previously clustering around the mid-30s, which is much closer to the historical seasonal baseline than the current zero print.[7]

A trader watching this contract should focus on the same variables that move the official reading: cloud cover, afternoon convection, rainfall, and any tropical system affecting northern Taiwan. The resolution source is Wunderground’s daily history page for Taipei Songshan Airport Station, so the relevant catalyst is not a citywide forecast headline but the actual station maximum by the end of the settlement window.[7] In practical terms, late changes in humidity, rainfall timing, and any tropical disturbance across the Taiwan Strait can shift the day’s high by enough to move the contract between adjacent Celsius bands, especially once local morning heating and afternoon showers become clearer.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.
