Highest temperature in Seoul on July 13?

Platform comparison

Market context

Seoul is experiencing a clear, dry start to 13 July 2026, with current conditions at Incheon International Airport showing minimal cloud cover and winds from the south at 10 knots. The day’s forecasted maximum sits near 31°C, aligning with typical mid-summer highs for the region, though the 0% crowd-implied probability for any extreme heat outcome suggests traders expect temperatures to remain within standard seasonal bounds.

Historical data for Incheon in early July shows average highs between 28°C and 32°C, with rare spikes above 35°C only during intense heatwaves linked to Pacific subtropical ridges. Comparable cases from 2023 and 2024 saw July 13 maxima of 30.5°C and 31.2°C respectively, reinforcing the view that an outlier event is unlikely without a confirmed atmospheric anomaly. This context supports the current market pricing, which treats extreme heat as a near-zero probability.

Traders should monitor real-time updates from the Korea Meteorological Administration and Wunderground’s hourly logs for RKSI, particularly any sudden shifts in humidity or wind direction that could signal a heat surge. While no scheduled political debates or campaign disclosures directly influence weather, broader regional climate declarations from the East Asian Meteorological Forum could offer early signals on ridge development. The market leans on immediate observational data rather than policy catalysts, making live temperature feeds the primary driver of price movement.

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 on July 13? 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

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

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.

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.
