Highest temperature in Taipei on July 23?

Platform comparison

Market context

The relevant real-world event is the highest temperature recorded at Taipei Songshan Airport during the day, with settlement tied to the Wunderground history page for 23 July 2026. In prediction markets, a **YES** share pays out if the specified outcome happens and a **NO** share pays out if it does not, so the price is the crowd’s view of whether a given temperature band will end up containing the day’s peak.

The current 0% YES implies traders see the stated range as effectively impossible, which is a very strong signal but not the same as certainty. That should be read against Taipei’s normal July heat: travel and climate guides describe July as the city’s hottest month, with average daytime highs around 33-34°C, and notes that readings often sit within a narrow band near 34°C, although hotter spikes can occur[2][4]. A market on the day’s maximum temperature is usually driven by the difference between an ordinary very hot afternoon and an exceptional one, rather than by morning conditions alone[2][4].

For traders, the key catalysts are local weather developments between now and the settlement window, especially sunshine, cloud build-up, sea-breeze effects and afternoon rain or thunderstorms, which can cap the high even in a hot summer pattern[4][5]. The current weather snapshot already shows Taipei as clear and very warm, with high humidity, but that only describes present conditions and not the eventual daily maximum[1]. Because settlement uses the station’s recorded high on the Wunderground history page, any late-day temperature surge or rain-cooled afternoon will matter more than the early-morning reading[1].

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 Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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 Prediction Market UK. 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 Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
