Highest temperature in Shanghai on August 15?

Platform comparison

Market context

Shanghai's highest temperature on 15 August 2026 will be measured at Pudong International Airport Station and resolved against Weather Underground's Daily Observations table. The market currently shows 0% probability, suggesting traders expect the actual recorded high to fall outside whatever temperature range this market option represents—though the specific threshold for this particular option is not stated in available documentation.

August temperatures in Shanghai are consistently elevated. Historical data from the China Meteorological Administration shows that mid-August highs in Shanghai typically range between 32°C and 35°C, with occasional peaks above 36°C during heat waves. The 30-year average high for mid-August sits around 32.5°C. The 0% implied probability suggests either the market option covers an unusually narrow or extreme range, or traders are heavily confident in a specific outcome based on seasonal patterns and any available medium-range forecasts for that particular date.

Traders monitoring this market should track China's meteorological forecasts as August 2026 approaches. The China Meteorological Administration issues extended outlooks roughly two weeks in advance, with increasing precision as the settlement date nears. El Niño or La Niña conditions could influence regional temperature patterns; current oceanic indices should be monitored through mid-2026. Real-time weather data from Wunderground will be the definitive source, making station-specific readings at Pudong the critical resolution point rather than city-wide estimates or alternative weather services.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
