Highest temperature in Chengdu on July 20?

Platform comparison

Market context

Chengdu’s July climate is defined by intense heat and high humidity, with average daily maximums reaching 31°C and frequent spikes into the 35–38°C range. The market’s current 0% probability for any outcome other than the frontrunner suggests the crowd has locked in a specific temperature band, likely 38°C, as the near-certain peak for 20 July 2026. This extreme confidence mirrors how prediction markets often behave once historical weather patterns and seasonal forecasts converge on a single plausible outcome, effectively treating the event as settled before the settlement window closes.

Historically, Chengdu experiences boisterous summer conditions, with July averaging 75% relative humidity and 50% chance of rain, yet heatwaves regularly push temperatures above 35°C. Comparable weather markets in recent years have shown similar clustering around the most probable high-temperature range once seasonal models stabilise, often rendering alternative outcomes virtually irrelevant. The 100% assignment to 38°C reflects this precedent, where traders treat the forecast as definitive rather than speculative, much like how Eurovision’s 50/50 jury-televote split eventually converges on a clear winner once voting patterns solidify.

Traders should monitor the official Wunderground daily history for ZUUU (Chengdu Shuangliu International Airport) as the primary resolution source, watching for any real-time temperature anomalies or station recalibrations announced by local meteorological authorities. While no specific announcement has been made yet, the China Meteorological Administration typically releases updated summer heatwave advisories in early July, which could shift expectations if extreme conditions are forecasted earlier or later than anticipated. Given the settlement deadline of 2026-07-20T12:00:00Z, any deviation from the 38°C consensus would require an unforecasted weather event, making the current probability a reflection of seasonal reliability rather than uncertainty.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

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.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

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.
