Highest temperature in Guangzhou on August 6?

Platform comparison

Market context

Guangzhou’s airport weather benchmark is usually set by heat, humidity and showers rather than by a single sharp spike, so the key question is whether afternoon warming can outpace cloud and rain at Baiyun Airport. Current forecast ranges for early August cluster around the low 30s Celsius, with AccuWeather showing daily highs around 31–32°C and BBC Weather putting today’s airport high at 32°C with light rain showers[1][11].

That makes the market’s 0% yes price look anchored to a belief that the eventual recorded high will stay below the top temperature bands often associated with a clear hot day in Guangzhou. Climatology is not especially supportive of an extreme upside move: August is typically hot, humid and wet, with average highs around 33°C to 34°C in several guides and forecasts, but also frequent rainfall and heavy cloud that can suppress the day’s maximum[7][16][18].

The main catalyst to watch is the same-day evolution of shower coverage and any late-morning or early-afternoon clearing at the airport, because that will determine whether the station can briefly exceed forecast highs. Traders will be leaning most on the near-term weather updates from forecast providers, especially BBC Weather and AccuWeather, since both currently imply a warm but rain-affected day rather than a runaway heat event[1][11][15].

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 Guangzhou on August 6? 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.

UK Frequently Asked Questions

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.

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.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
