Highest temperature in Taipei on June 8?

Market context

On 8 June 2026, Taipei will experience early summer conditions, and traders on Polymarket are currently pricing zero probability that the day's peak temperature will fall into whichever range this market settles against. The contract resolves using Wunderground's historical data from Taipei Songshan Airport Station, the official reference point for the city's weather records. Settlement occurs at 12:00 UTC on the resolution date, giving traders a defined window to assess the actual high before conditional tokens are distributed across USDC on Polygon.

Taipei's June climate is remarkably consistent. Historical records show the city averages a high of 31–32°C during early June, with extreme highs rarely exceeding 35°C except during unusual heat events. The 0% crowd probability suggests either extreme confidence in a specific temperature band or minimal liquidity driving the market to an edge case. Comparable June days over the past decade have clustered tightly around 30–33°C, making outlier scenarios—sub-28°C or above-36°C—statistically unlikely but not impossible. Typhoon season begins in earnest later in June, though individual storms in the first week remain uncommon.

Traders should monitor the Central Weather Administration Taiwan's forecasts in the week preceding 8 June, particularly any alerts for unusual pressure systems or tropical activity. El Niño or La Niña conditions active in early 2026 could shift baseline temperatures marginally. Real-time data from Songshan Airport becomes the arbiter; the station's elevation and coastal proximity mean sea-breeze effects and urban heat island dynamics both influence daily maxima. Any significant weather announcement from Taiwan's meteorological service in late May would warrant reassessing the current market pricing.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Kalshi UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Kalshi UK triggers a quick verification flow that finishes in minutes.

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.
