Highest temperature in Taipei on July 24?

Platform comparison

Market context

Polymarket is pricing the contract with a strong tilt towards a relatively hot reading: the market currently puts **35°C** in front at **25%**, with **32°C** next at **19%**. Because shares settle at **$1** only if the exact outcome range matches the highest temperature recorded at Taipei Songshan Airport on the day, the 0% crowd-implied price on the broader “YES” framing is only useful as a snapshot of where traders think the tail risk sits on the temperature ladder, not as a statement that a heat spike is impossible.[1]

For context, Taipei in July is typically hot, humid and unsettled rather than stable, with average highs around the low 30s and frequent rain; one weather guide puts typical July highs near **33°** and rainfall at about **197 mm** over the month. That pattern matters for reading a 24 July print: cloud cover and showers can cap the top end, but clear spells can still push the daily maximum into the mid-30s, which is consistent with the market’s current concentration around 32–35°C rather than the cooler bins.[2][4]

A trader watching this contract should focus on the day’s synoptic setup over northern Taiwan, plus any forecasts for sunshine, sea-breeze suppression, or afternoon convection that could shift the peak temperature by a degree or two. Since the market resolves from Wunderground’s Taipei Songshan Airport Station history page, the key dependency is the station’s recorded high before the settlement window closes, not the citywide average; on Polymarket, that means USDC is locked into conditional tokens on Polygon until the outcome range is confirmed and the relevant shares can redeem for par.[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 Kalshi UK, 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.
