Market context

On 11 June 2026, the highest temperature recorded at London City Airport will fall into one of several defined ranges. The settlement mechanism pulls directly from Wunderground's historical weather database for that specific station and date, making this a straightforward instrumental market once the day passes. For traders building automated resolution workflows, the data feed is stable and publicly accessible; the gear-icon toggle between Celsius and Fahrenheit is a minor operational detail but worth scripting around if you're batching multiple temperature markets across regions.

Historical June temperatures at London City Airport cluster between 18°C and 24°C on average, though outliers do occur. The 0% crowd probability suggests either thin liquidity or genuine uncertainty about which temperature band will resolve. Comparable markets on UK airport temperatures show that late spring weather patterns—particularly jet stream positioning and Atlantic pressure systems—drive meaningful variance. A trader evaluating this market programmatically should cross-reference Met Office seasonal outlooks and recent synoptic charts rather than relying on simple climatological means.

The settlement window closes at 12:00 UTC on 11 June, creating a hard deadline for data collection. Wunderground's historical records typically populate within hours of day-end, but conditional order logic should account for occasional delays in station reporting. For systematic traders, this market functions as a calibration tool: comparing your own weather model outputs against the resolved range reveals whether your temperature forecasting assumptions track reality or require adjustment before deploying capital on subsequent June days.

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.
