Lowest temperature in Shanghai on July 19?

Platform comparison

Market context

Shanghai's lowest temperature on 19 July 2026 will be recorded at Pudong International Airport Station and measured in Celsius. The settlement hinges on historical weather data retrieved from Weather Underground, which archives daily temperature extremes for this specific monitoring location. July is Shanghai's peak summer season, with typical daily lows ranging between 24–27°C, though occasional heat waves can suppress minimums further and rare cooler systems might push them lower.

The 0% crowd probability reflects the market's structure rather than meteorological implausibility. These temperature-range markets typically suffer from low liquidity and sparse trading activity, particularly for specific geographic stations and narrow daily windows. Historical precedent from comparable weather markets shows that extreme outcomes—either unusually cold or warm days—attract sporadic late trading as forecasts sharpen closer to settlement. Shanghai's monsoon patterns and occasional tropical systems make late-July conditions moderately volatile; the China Meteorological Administration issues 10-day forecasts that traders should monitor for any anomalous pressure systems approaching the Yangtze River Delta region in mid-July 2026.

Traders should watch for any announced typhoon activity or upper-air disturbances in the Western Pacific during early-to-mid July, as these can suppress daytime heating and lower overnight minimums. Wunderground's historical archive for this station is reliable but occasionally subject to minor data corrections after initial publication. The settlement window closes at noon UTC on 19 July, allowing only morning observations to count; traders should verify the exact cutoff against the station's reporting schedule.

FAQ

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
