Highest temperature in Taipei on August 2?

Platform comparison

Market context

The event is whether Taipei Songshan Airport records a maximum near the upper 30s Celsius by the daily cut-off, and the prediction market is already pricing that as the dominant outcome, with **37°C** on **37%** and **36°C** on **33%**. That leaves a comparatively thin tail for hotter outcomes, with **38°C** at **18%** and **35°C** at **14%**, which is a much tighter distribution than the flat 0% YES crowd-implied line might suggest if read as a categorical over/under rather than a range contract.[1]

For context, August in Taipei is normally hot and humid, with climate references putting typical highs around the low-to-mid 30s Celsius, while one weather guide notes August highs around **36°C** and another shows monthly highs around **32–34°C** depending on the dataset.[2][4][5][16] That history supports a market clustered around 36–37°C, but it also explains why the contract can move sharply on small forecast changes: a one-degree shift in cloud cover, sea-breeze penetration, or afternoon rain can decide whether the day peaks in the 35–36°C band or pushes into 37°C-plus territory.[1][14]

For traders, the main catalysts are the same-day forecast updates and any change in the timing or intensity of showers, thunderstorms, or typhoon-related cloud bands over northern Taiwan, because those factors most directly affect the daytime maximum.[10][12][14] A recent weather summary for Taiwan on 2 August points to showers in parts of the island and a Taipei temperature near the low 30s on that day, but the contract is resolved on the **single highest reading** at Songshan Airport, not the city-wide average, so brief late-afternoon clearing can still matter.[14] Apple-to-apple sportsbook lines are scarce for this exact temperature band, so the useful comparison is against meteorological consensus: the crowd is slightly more aggressive on 37°C than the broader climate norms, but not wildly out of line with peak-summer extremes in the city.[1][20]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
