Highest temperature in Beijing on July 24?

Platform comparison

Market context

Beijing’s airport weather on 24 July will be decided by a single day’s high, and the market is currently pricing that outcome at **0% YES**. For context, July in Beijing is typically the city’s hottest and one of its wettest periods, with average highs around 31°C to 33°C and frequent rain that can cap daytime temperatures even when sunshine pushes readings higher.[1][3]

That makes the comparison set fairly narrow: in a normal July pattern, the airport should land somewhere in the low-30s, but heavy rain, cloud cover or a thunderstorm can keep the realised maximum below the upper bands that would matter for this contract.[1][3] The key read-through from comparable summers is that Beijing can still produce spikes towards 35°C or above, but those are usually tied to clear, hot spells rather than the more common mixed, humid monsoon conditions.[3]

For traders, the main catalyst is the live weather sequence around the airport itself, not citywide sentiment: updated forecasts, rainfall timing and whether the afternoon remains dry enough for the temperature to peak. The market is leaning on short-horizon weather guidance rather than any political-style event schedule; the nearest analogue to a catalyst is a forecast revision from a major weather outlet or aggregator such as BBC Weather as conditions evolve through the day.[2]

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Highest temperature in Beijing on July 24? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

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.

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 Election Predictions UK 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.

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.
