Highest temperature in Seoul on July 10?

Platform comparison

Market context

Seoul is currently experiencing an intense early-July heatwave, with temperatures reaching 37.7°C on Tuesday, marking the highest early-July reading in 117 years of record-keeping since 1908[1][6]. Nearby western cities like Gwangmyeong and Paju have already surpassed 40°C, setting new national records for July highs[1]. This extreme thermal activity frames the current 0% crowd-implied probability for a lower temperature range, as historical data shows Seoul’s all-time peak of 38.3°C was recorded precisely on July 10, 1946[10]. The convergence of record-breaking regional highs and the specific date alignment suggests traders are leaning on the catalyst of the 1946 historical benchmark, reinforced by the Korea Meteorological Administration’s confirmation of unprecedented heat[1].

Traders should monitor daily Wunderground updates for the Incheon Intl Airport Station, as the resolution hinges on the highest temperature recorded at any time on July 10, 2026[3]. The market is heavily influenced by the ongoing heatwave, which has also produced 22 tropical nights in Seoul, a record for the month[5]. Recent announcements from the Korea Meteorological Administration regarding the heatwave’s persistence are critical, as they indicate the likelihood of temperatures exceeding 38°C again[1]. With July 8 already hitting 37.8°C, the most significant catalyst is the potential for a repeat of the 1946 peak, a scenario supported by the current trajectory of record-breaking temperatures across western South Korea[2][6].

FAQ

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.

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.
