Market context
Beijing's highest temperature on 14 July 2026 will be measured at the Capital International Airport Station and resolved against historical weather data. July is consistently the hottest month in Beijing, with average highs around 29–31°C, though extreme heat waves can push readings several degrees higher. The settlement mechanism relies on Wunderground's historical records for this specific station, which maintains continuous meteorological monitoring.
Historical July temperatures at Beijing Capital Airport show a range of outcomes. Since 2010, July highs have typically fallen between 28–35°C, with occasional peaks above 36°C during heat waves. The 0% crowd probability suggests traders are either uncertain about the resolution mechanism or treating this as a calibration exercise rather than a genuine forecast. Comparable weather markets on this platform have shown that crowd confidence in temperature ranges often reflects recent seasonal patterns rather than year-specific anomalies.
Traders should monitor China Meteorological Administration forecasts as July 2026 approaches, particularly any alerts for heat waves or unusual atmospheric conditions in the North China Plain. The Beijing municipal government publishes heat warnings through official channels when temperatures are expected to exceed 35°C. Since this market settles on a single day's maximum rather than seasonal averages, short-term weather pattern shifts in early-to-mid July will be the primary driver. Wunderground's historical data feed is the binding resolution source, making data availability and station continuity the critical technical dependencies.

This page tracks Highest temperature in Beijing on July 14? across four political prediction venues. Live odds come from the Polymarket order book (the deepest political prediction-market book).

For users geo-blocked from Polymarket directly, brokers like Trump Prediction provide a 0%-fee route into the same order book.
Resolution & payout
For political markets the resolution source is decisive. Polymarket defines a concrete source per contract (e.g. AP, Reuters, official electoral commission) and uses the UMA Optimistic Oracle as the on-chain dispute mechanism. With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.
FAQ
- 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.
- How fast do political markets react to news?
- High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.
- 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.
