Highest temperature in Beijing on July 16?

Platform comparison

Market context

Beijing faces its peak summer heat on 16 July 2026, with the market betting on whether the highest temperature at Beijing Capital International Airport will hit a specific threshold. The crowd currently assigns a 0% probability to the YES outcome, suggesting traders expect conditions to fall short of the required range, despite July being the city’s hottest month with average highs of 31°C and frequent spikes to 35°C or more[2][3].

Historical data frames this low probability as plausible but not definitive: in 2024, July’s peak reached 37°C, and two-thirds of July days exceed the average maximum[3]. Comparable years show that while 33°C is the market’s frontrunner at 39%, with 34°C at 27%, extreme heat events remain possible due to the humid, monsoon-driven climate that brings afternoon thunderstorms and occasional temperature surges[1][2].

Traders should monitor real-time weather updates from Wunderground, the official resolution source, as well as forecasts for thunderstorm activity that could suppress peak temperatures[1]. No political catalysts, debates, or campaign-finance disclosures influence this weather market; the sole dependency is atmospheric conditions on the settlement day. The market leans on the immediate forecast rather than scheduled events, making live temperature data the critical indicator for position adjustments.

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.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

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.
