Highest temperature in Taipei on July 12?

Platform comparison

Market context

Taipei Songshan Airport is currently overcast with a temperature of 27°C and a heat index of 31°C, while July remains the hottest month on record with an average high of 36°C [1][4]. The prediction market for the highest temperature on 12 July 2026 prices the YES outcome at 0%, implying the crowd expects the peak to fall outside the specific range offered, despite the seasonal norm for mid-July heat [9]. Historical data shows Taipei frequently exceeds 35°C in July, making a 0% probability for a high-temperature range statistically unusual unless the bracket is set implausibly low or the market is illiquid [1].

Traders must monitor the Central Weather Administration’s hourly updates and the final Wunderground daily record, as settlement depends entirely on the single highest reading published for RCSS by 12:00 UTC [6]. Current conditions show 88% humidity and 12 mph winds, which may suppress peak temperatures compared to dry, sunny July days that routinely hit 38°C [3][4]. The on-chain mechanics on Polygon use USDC and conditional tokens, meaning liquidity depth will dictate whether the 0% price reflects genuine consensus or a lack of opposing volume before the 2026-07-12 settlement window closes [2]. No official weather announcements are scheduled beyond routine observations, so the catalyst is simply the official data release from Wunderground.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
