Highest temperature in Hong Kong on August 4?

Platform comparison

Market context

Hong Kong’s maximum temperature on 4 August will be set by the Hong Kong Observatory’s final “Absolute Daily Max” reading for that date, with settlement using the value published in its Daily Extract and rounded to one decimal place. With the market currently pricing a 0% chance of **YES**, the crowd is effectively saying the eventual reading will not land in the qualifying range, despite the fact that August in Hong Kong is usually among the hottest parts of the year.[11][7]

That scepticism should be read against a fairly warm baseline rather than an extreme-heat expectation. Seasonal and month-ahead guides put Hong Kong’s August daytime highs around **31–32°C**, with heavy humidity and frequent rain, while forecast pages for early August lean closer to the **29–31°C** band, implying that cloud cover and showers can easily shave a degree or two off the daily maximum.[1][8][12] In other words, a reading in the high 20s or low 30s would be normal, while a decisive spike above that would need unusually clear, stagnant conditions.

The main catalyst for traders is the official weather sequence over the next few hours: the Observatory’s short-range forecasts, any rain-band or thunderstorm updates, and whether convective showers move through during the afternoon heating window. Regional forecast pages currently show mixed rain and thunder signals rather than a clean heat breakout, which supports the view that the day’s peak will depend on timing as much as on background seasonal warmth.[9][15] Until the Observatory publishes the finalized daily extract, the market will stay tied to those immediate forecast revisions rather than to the seasonal average alone.

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 4? 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

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.

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.
