Highest temperature in Taipei on July 31?

Platform comparison

Market context

Taipei Songshan Airport’s afternoon high on 31 July is the underlying event, and the crowd is pricing a **0% YES** outcome, so the market is treating the required temperature band as a deep underdog. That is an extreme stance for late July in Taipei, where climatology is firmly hot: July averages sit around the low 30s Celsius, with published monthly guides commonly showing average highs near **32–33°C** and occasional peaks well above that, into the **high 30s**.[2][10][12][13]

For handicapper framing, the favourite is clearly the broader high-temperature range that covers a normal Taipei summer peak, while the market’s 0% consensus implies no premium for an upside heat spike. Historical comparables argue against writing off the hot end entirely: Taipei has recorded extreme summer heat, and recent reporting says temperatures topped **36°C** for a third straight day on Friday, which keeps the hotter ranges live if the urban heat pattern persists.[1][11] The value question is whether the consensus has overdiscounted a routine late-July high rather than an exceptional one; in other words, the contrarian angle is to lean into the upper bands if the day turns sunny and dry.

Traders should watch the same-day synoptic setup rather than a scheduled event calendar: cloud cover, afternoon showers, and any weakening of the subtropical heat ridge are the main catalysts for Songshan’s maximum. Because the settlement source is Wunderground’s station history for Taipei Songshan Airport, the key dependency is the observed airport reading by the 12:00 UTC close, not a citywide forecast.[1] Any late-morning rain band or maritime breeze would favour the lower ranges; a clear, stagnant afternoon would support the hotter consensus outcome.

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 Who Will Win, 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.

FAQ

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.

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
