Highest temperature in Seoul on July 27?

Platform comparison

Market context

Seoul’s heat outcome on 27 July will be set by the highest reading at Incheon Intl Airport Station, and the immediate backdrop is a mixed summer setup rather than a clean heat spike. South Korean media reported severe heatwave warnings nationwide, but also said showers are expected in the capital region from the morning, with Seoul forecast at 26–33°C and daytime highs across the country ranging from 28–36°C.[1]

That places the market in line with a familiar July pattern: hot, humid conditions with rain interruptions, not a guaranteed extreme. Seasonal guides for Seoul describe July as one of the wettest months, with daytime highs typically around 27–30°C and occasional pushes into the low 30s, while the record July temperature in Seoul was 38.4°C.[8][10][11] Against that history, a 0% implied chance of the top bucket looks anchored to the absence of any forecast for exceptional heat, especially with cloud and shower risk limiting upside.[1]

The main catalyst to watch is whether the morning rain band clears quickly enough for stronger afternoon heating; if showers linger over the capital area, the airport station’s maximum is likely to stay close to the low or mid-30s Celsius rather than breaking out higher.[1] For traders, the key dependency is the hourly progression in the Incheon/Seoul forecast, alongside any updated warnings or rainfall adjustments from local forecasters, because the market resolves on the day’s *single highest* temperature, not the daily average.[1]

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.

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.

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.

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.
