Highest temperature in Shenzhen on July 17?

Platform comparison

Market context

Shenzhen’s Bao’an International Airport is expected to record its peak daily temperature on 17 July 2026, with the market currently pricing any outcome above the lowest bracket at zero probability. Historical data shows July in Shenzhen is consistently hot and humid, with average daily highs reaching 31.1°C and rainfall averaging 211.2mm across roughly seven days [1]. This climatic baseline makes a 0% YES probability for higher ranges appear misaligned with typical seasonal patterns, suggesting the crowd may be underweighting standard summer extremes or reacting to a specific short-term forecast anomaly.

Comparable cases from recent years indicate that temperatures in Shenzhen frequently exceed 30°C in mid-July, reinforcing the statistical likelihood of higher ranges than the current frontrunner of 27°C, which holds 43% implied probability [2]. The market’s next closest outcome, 28°C, sits at 34%, further highlighting a concentration in the lower brackets despite the region’s known heat intensity [2]. Traders should monitor real-time weather updates from Wunderground, the official resolution source, as well as any sudden shifts in regional cloud cover or monsoon activity that could suppress temperatures [2]. No scheduled political debates or campaign-finance disclosures influence this weather event; the sole catalyst is the meteorological data recorded at the airport station on the settlement date.

FAQ

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.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
