Highest temperature in Shanghai on July 10?

Platform comparison

Market context

Shanghai’s July climate is defined by intense heat and humidity, with daytime highs routinely exceeding 35°C (95°F) and peaking around 3 PM. Historical data from the Shanghai Pudong International Airport shows that late July often delivers the year’s hottest days, with 28 July typically reaching 38°C (100°F) in recent years. The 0% crowd-implied probability for a specific temperature range on 10 July likely reflects the date’s position in early July, when averages sit slightly lower—around 29.8°C (85.6°F)—compared to the month’s peak. Yet, extreme outliers remain possible, as 2025 saw a 38°C spike, meaning traders should not dismiss volatility despite the current low probability.

Traders must monitor real-time weather updates from Wunderground and AccuWeather, which forecast daily highs between 86°F and 97°F for July 2026 at Pudong Airport. While no political debates or campaign-finance disclosures directly influence temperature, sudden shifts in solar radiation or wind speed—both increasing through July—could trigger unexpected heat spikes. The market leans on the catalyst of natural weather variability rather than human events, so close attention to hourly forecasts from Yr.no and National Weather Service data is essential. Any deviation from the 30–31°C average could reshape the probability landscape, making early July 10 a day of potential surprise.

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.

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.

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.

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.
