Highest temperature in Seoul (Incheon) on August 6?

Platform comparison

Market context

Seoul and nearby Incheon are under a severe heatwave, and the practical question for this market is whether the airport station gets anywhere near the upper end of today’s forecast range before the afternoon peak. Korean Meteorological Administration reporting cited by Asiae puts Incheon at **38°C** and Seoul at **39°C**, while SBS English says Seoul could match its highest temperature of the summer at **39°C**.[1][2]

That makes the current **0% YES** crowd view look anchored to the idea that Incheon will stay below the market’s highest bracket, despite the extreme conditions. The historical comparator is not a single-day August anomaly but a broader pattern: early August is normally the hottest point of the Seoul summer, and Weather Spark notes that Seoul’s highest average daily high in August falls on **6 August**.[15] Asiae also reports that Seoul has only exceeded **39°C once** in modern observations, at **39.6°C in 2018**, which frames how unusual a 40°C-type outcome would be.[10]

The key catalyst to watch is the official day-of forecast and whether temperatures at Incheon Airport can catch up with the inland Seoul heat as the day develops. Korea’s short-range outlook and live airport observations matter most here, because the settlement source is the Wunderground history page for **Incheon Intl Airport Station** rather than central Seoul.[9] Asiae says the heatwave warning remains in force across the capital area, with only temporary relief from rain or showers before humidity pushes temperatures back up again.[1]

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 Seoul (Incheon) 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

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.

UK Frequently Asked Questions

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.

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.

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.

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.
