توقع: Highest temperature in London on July 20?

Platform comparison

Market context

London City Airport recorded a peak of 22.3°C (72.1°F) on 20 July 2023, a figure that aligns closely with the current market favourite of 72–73°F, which now carries 100% implied probability after resolving as “Yes” on Polymarket [1]. This historical precedent suggests the 0% current crowd-implied probability for the “Will it be between 72–73°F?” outcome is a mispricing error, likely stemming from a lag in data ingestion rather than a genuine shift in meteorological expectation. July in London typically sees highs between 18°C and 24°C, with 2023’s 22.3°C representing a solid mid-range summer day rather than an outlier, reinforcing the statistical likelihood of this range recurring.

Traders should monitor the official Wunderground daily history for EGLC, the designated resolution source, for any discrepancies between real-time sensor readings and the archived daily maximum [1]. The settlement window closes at 12:00 UTC on 20 July 2026, meaning the market will resolve based solely on the highest temperature recorded at any point on that calendar day, regardless of when the peak occurs. No recent weather announcements or injury-style catalysts apply here; the only dependency is the accuracy of the EGLC station’s data feed and the timely publication of the daily summary on Wunderground. Given the 2023 precedent and typical July climatology, the 0% probability appears fundamentally disconnected from observable historical patterns.

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
