Highest temperature in Kuala Lumpur on July 19?

Platform comparison

Market context

Kuala Lumpur's equatorial climate produces consistently high daily maxima, yet Polymarket currently prices this contract at 0% YES, suggesting traders are either avoiding the market entirely or expect the settlement data to fall outside all available temperature ranges. The settlement mechanism depends on Wunderground's historical records for Kuala Lumpur International Airport on 19 July 2026, with USDC collateral locked in conditional tokens on Polygon until the outcome resolves. The 0% probability reflects either extreme confidence in a specific temperature band or minimal liquidity, making this a thin market where early position-taking could shift prices substantially.

July represents Kuala Lumpur's monsoon season, when afternoon thunderstorms frequently suppress peak temperatures. Historical data from the airport station shows July daily maxima typically range between 31–34°C, with occasional spikes to 35°C during drier years. The 2015 El Niño event produced elevated temperatures across Southeast Asia, whilst the 2016 La Niña brought cooler conditions. These precedents suggest the market's zero probability may reflect traders' uncertainty about which temperature band the contract offers, rather than genuine conviction about the weather outcome itself.

Traders monitoring this contract should track the Malaysian Meteorological Department's seasonal forecasts and any updates to monsoon intensity predictions as July 2026 approaches. The settlement window closes at 12:00 UTC on 19 July, giving traders until midday to adjust positions based on morning weather reports. Real-time temperature data from airport weather stations typically updates hourly, allowing late-stage position refinement as the day progresses.

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