Highest temperature in Shanghai on July 16?

Platform comparison

Market context

Shanghai is currently experiencing overcast conditions with temperatures around 28°C at the Pudong International Airport, yet the market for the highest temperature on 16 July 2026 remains locked at 0% for any outcome, suggesting a technical anomaly or premature settlement rather than a genuine forecast of cool weather. This stands in stark contrast to historical July patterns, where the city routinely records peak temperatures between 27°C and 36°C, with the month often ranking as one of the hottest periods of the year due to persistent humidity and limited rainfall breaks [3]. Comparable data from the recent 7 July 2026 event shows the market confidently pricing 34°C as the frontrunner with 100% probability, indicating that the current 0% figure for the 16 July market likely reflects a lack of liquidity or a resolution error rather than an expectation of sub-20°C conditions [1].

Traders should monitor the official Wunderground daily history for the Pudong station, which serves as the definitive resolution source, while watching for any scheduled meteorological declarations from local Chinese authorities regarding heatwaves or extreme weather advisories ahead of the settlement window. Although no specific political debates or campaign-finance disclosures directly influence weather outcomes, the market’s current stagnation may be linked to broader data feed delays or a lack of active participants in this non-political weather category on a platform primarily focused on political events. The absence of recent news coverage on Shanghai’s specific heat forecast for mid-July 2026 means the primary catalyst remains the raw temperature reading itself, which historically aligns with the upper end of the July average range [3]. Given the 0% probability, the market is leaning on the possibility of a data error rather than a genuine climatic shift, as historical averages strongly contradict the implied certainty of a cold day.

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.

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.
