Highest temperature in Seoul (Incheon) on August 2?

Platform comparison

Market context

A hot spell over the Seoul–Incheon area is the real-world driver here, with forecasters calling for daytime highs around 33–39°C across South Korea and Incheon specifically near 33°C, while the market’s current crowd view still leans to the low-30s rather than an extreme outcome.[2][3][1]

That framing matters because the distribution of likely outcomes is clustered around 32–33°C, with 32°C currently the leading price and 33°C close behind, while 34°C is a much smaller tail.[1] In other words, the market is not pricing a broad temperature collapse or a breakout well above the forecast band; it is mostly debating whether the day tops out at the lower or upper edge of the expected range.[1][2] The comparison set is straightforward: under typical August conditions, Seoul and Incheon often sit in the high 20s to low 30s, so a reading in the low 30s would be hot but not exceptional for the season.[9][13]

The main catalyst to watch is the Korea Meteorological Administration’s short-range guidance and any same-day revisions if the heat intensifies or cloud cover, sea breeze, or rainfall caps the afternoon maximum.[5][10] Reuters reported that South Korea has just come through a record-breaking heatwave, which supports a higher-than-normal baseline for near-term forecasts, but local news also shows the expected Seoul/Incheon peak remains concentrated around the mid-30s rather than the upper 30s or 40s.[11][7][2] For traders, the key dependency is whether the airport station records its maximum early enough in the afternoon to stay inside the forecast band, or whether persistent heat pushes the reading one notch higher.[1][2]

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.

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.

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.
