Highest temperature in Seoul on July 7?

Platform comparison

Market context

Seoul’s highest temperature on 7 July 2026 is expected to fall within the 27–28°C range, based on historical averages and recent market activity, despite the current crowd-implied probability of 0% for the “YES” outcome. This market resolves to the temperature bracket containing the peak reading at Incheon International Airport, sourced from Wunderground, and will settle by 12:00 UTC on 7 July 2026.

Historically, Seoul’s July daytime highs climb from 81°F to 85°F (27.2°C to 29.4°C), rarely dipping below 74°F (23.3°C) or exceeding 91°F (32.8°C)[2]. In 2025, South Korea recorded its second-hottest July since 1973, with an average of 27.1°C, while Seoul hit 37.7°C in early July—the highest in 117 years[6][8]. These precedents suggest the 0% probability is likely misaligned with climatic norms, as temperatures in this bracket are typical for mid-July.

Traders should monitor upcoming weather forecasts from the Korea Meteorological Administration and any sudden shifts in tropical night streaks, which have recently broken century-old records in Seoul[7][9]. No scheduled political debates or campaign-finance disclosures directly influence this market; the primary catalyst is atmospheric data. The market leans on Wunderground’s real-time temperature logs, with no external political or financial events expected to alter the outcome[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.

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.

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.
