Highest temperature in Hong Kong on August 6?

Platform comparison

Market context

Hong Kong’s hottest readings in August are usually well above the low-30s Celsius, and the Observatory’s climate normals put the 6 August mean maximum at 31.6°C, with the monthly average maximum around 32°C. That makes the market’s 0% YES price look anchored to an expectation that the day will not deliver an unusually high top-end reading, even though the city has a long history of late-summer heat spikes and occasional extremes above 35°C.[2][8][11]

The nearest comparable frame is recent August weather in Hong Kong rather than a political analogue: 2024 was described by the Observatory as an exceptionally hot August, with a mean daily maximum of 32.3°C, 1.0°C above normal.[4] By contrast, the current forecast picture is less severe, with AccuWeather showing highs around 31–32°C for 5–9 August and only a modest uptick thereafter, which points to a more typical hot, humid spell than a record-setting surge.[1]

For traders, the key catalyst is the Hong Kong Observatory’s final “Daily Extract” for 6 August, because settlement depends on the published “Absolute Daily Max (deg. C)” in Celsius to one decimal.[3] Until that data is posted, the market is effectively leaning on short-range forecast evolution, especially whether cloud, rain, or a warm southerly flow suppresses the afternoon peak; if the forecast shifts towards a drier, sunnier profile, the upper temperature bands become more relevant, but the present consensus still appears to favour an ordinary summer maximum rather than a standout extreme.[1][3]

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 Hong Kong 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.

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.

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.

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.

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.
