Highest temperature in Kuala Lumpur on July 30?

Platform comparison

Market context

Polymarket currently prices this Kuala Lumpur temperature contract with a **0% YES** crowd-implied probability, so the market is effectively saying the listed outcome has been dismissed for now rather than merely treated as unlikely. That is a useful starting point because the market settles off the **highest temperature recorded at Kuala Lumpur Intl Airport Station** on the day, as reported by Wunderground, and the result is based on the day’s peak observation rather than an end-of-day average. Shares are settled in **USDC** on **Polygon** via conditional tokens, so the practical question for traders is not the city’s climate in the abstract but whether the airport station prints into a particular Celsius band before the market’s settlement window closes.

Historically, July in Kuala Lumpur is hot and humid, with average highs around **31–33°C** depending on the climate series, and recorded July highs reaching the **mid- to high-30s Celsius** in some datasets.[1][4][6][14] Recent July climatology also shows that daily maxima frequently sit near **30–33°C**, with individual days varying materially from the monthly norm.[5][10] For a bin-style market like this one, that matters because a single brief afternoon spike can move the final outcome into a higher range even if most of the day looks ordinary. The present 0% price therefore reads less like a temperature forecast and more like a statement that the crowd sees the specified Wunderground station data as unlikely to land in that bucket.

The main catalysts are straightforward: the **day’s actual airport observations**, any convective showers or clearing that affect afternoon heating, and the timing of the highest reading before the settlement cut-off. Kuala Lumpur’s July climate is rain-prone enough that cloud cover and showers can cap highs, while clearer breaks can push temperatures up quickly.[1][14] Traders should watch the Wunderground history page for the airport station itself, not city forecasts alone, because the market resolves to that source’s recorded maximum. Since the market closes its settlement window at **12:00 UTC**, late-morning and early-afternoon Malaysian conditions are the key dependency for the final print.

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.

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.

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