Seoul July 11 High Temperature: Will It Hit 32°C?

The Seoul temperature market has already done its work. A contract sitting at 97.4% implied probability with the resolution clock reading down to hours is not a debate. The market is pricing a near-certainty that Seoul’s highest temperature on July 11 lands exactly at 32°C. Here’s what the measurements are telling us: momentum surged over 36% in the past 24 hours, the trend score sits at 64, and traders moved more than $104,000 in a single day to get here.

The market question asks for the highest temperature recorded in Seoul on July 11, 2026. The YES outcome is 32°C. The NO price sits at 0.03, reflecting a 2.6% residual chance the reading lands elsewhere. Total traded volume reached $124,683, with resolution set for 2026-07-11 12:00:00 KST.

How the 32°C Contract Works

This contract resolves YES if Seoul’s officially recorded daily high temperature on July 11, 2026, equals 32°C. Alternative outcomes on the same platform include everything from 23°C or below up through 33°C or higher. Resolution depends on the official temperature measurement source designated by Polymarket for this market. The 32°C outcome is currently the overwhelming market consensus.

• YES (32°C): 0.97 price, 97.4% implied probability. Market expects this outcome with near-certainty.
• NO (any other outcome): 0.03 price, 2.6% implied probability. Covers all alternatives, from 31°C down to 31°C or lower, or 33°C or higher.

The NO side pays out if Seoul’s recorded high misses 32°C entirely. That means either a cooler-than-expected afternoon where readings stall at 31°C, or an unexpectedly intense spike pushing past 33°C. Seoul’s Korea Meteorological Administration stations measure official highs continuously. A thunderstorm, cloud cover shift, or wind pattern change in the final morning hours could shave or add a degree. The margin for the current measurement to shift is narrow, but it exists.

Momentum and Market Signals

The momentum composite here is unusually clean. A 36.5% price jump in 24 hours combined with a 64 trend score and flat movement in the last hour signals that traders reached conviction fast and stopped moving. The driver is almost certainly real-time weather data: July 10 brought multiple upward repricing events as Seoul’s afternoon temperatures tracked toward the 32°C range, and July 11 morning readings appear to have locked in trader confidence.

Total volume of $124,683 is modest by major market standards, and the 24-hour volume of $104,995 means roughly 84% of all trading happened in the last day. Liquidity sits at $285,778, which is healthy relative to volume. The data doesn’t care about the politics, but it does care about thin order books. A sharp measurement surprise in the final hours could move this price, even from 97.4%.

Key Factors

• The 24-hour price change of +36.5% combined with a trend score of 64 reflects a single decisive repricing event tied to observed Seoul temperature data on July 10 and early July 11.
• The 1-hour price change of +0.0% signals that conviction has stabilized. No new information entered the market in the most recent window.
• Volume of $104,995 in 24 hours against $124,683 total means this market built almost entirely on fresh information, not legacy positioning.
• Liquidity at $285,778 exceeds 24-hour volume, which reduces the risk of a thin-book price spike if new data arrives before resolution.
• The correlation with the Hong Kong July 10 temperature market is strongly positive, suggesting regional heat patterns across East Asia drove simultaneous repricing in both contracts.

Lines Analysis: Seoul Temperature on July Eleven

Seoul in mid-July sits in a period of seasonal heat that frequently produces daily highs in the low-to-mid 30s Celsius. The Korean Meteorological Administration’s historical records show July as the city’s hottest month, with average highs near 29-30°C and frequent excursions into the 32-34°C range during heat events. The market’s 97.4% confidence in exactly 32°C reflects a reading that likely matched observed temperatures through the morning of July 11, before the afternoon peak was officially logged.

The residual NO probability of 2.6% is not noise. A reading of 31°C or 33°C is physically plausible within a single degree of measurement precision. Afternoon cloud development, a sea breeze off the Yellow Sea, or a passing convective cell could trim the peak by a degree. Conversely, a sustained heat dome pattern could push the high to 33°C or above. The market is pricing uncertainty, not science, and it has priced that uncertainty very close to zero.

Signals to Monitor

• Korea Meteorological Administration official hourly temperature readings for Seoul station through midday July 11 will determine final resolution.
• Any satellite or surface observation showing afternoon convective activity over the Seoul metropolitan area would signal downside risk to the 32°C reading.
• The Hong Kong July 10 temperature market showed strong positive correlation, suggesting regional synoptic patterns are the dominant driver. Continued heat ridge persistence supports 32°C.
• If the official KMA daily high report releases before the 12:00:00 resolution timestamp, price will move immediately to reflect the confirmed number.
• A 33°C or higher reading would make the YES contract worthless despite 97.4% current pricing, representing the sharpest possible repricing scenario.

Total volume of $124,683 is thin by prediction market standards, but the liquidity ratio is sound. The data strongly favors YES. The only scenario where this contract reprices sharply is a confirmed temperature measurement outside the 32°C band before resolution closes.

LINES VERDICT

NEAR-CERTAIN YES

The 97.4% implied probability reflects real-time temperature data that traders used to reprice this contract dramatically in 24 hours. The market moved this fast because the observed Seoul temperatures tracked directly to the 32°C outcome.

What the market says: At 97.4% implied probability, this contract is priced as settled with hours remaining to resolution. Thin total volume means a late measurement surprise could cause sharper movement than the price suggests, but the window is closing fast.

Key unknown: The single event that would reprice this contract is the official Korea Meteorological Administration daily high reading for July 11. If that number lands at 31°C or 33°C before the 12:00:00 resolution timestamp, the YES contract collapses instantly.
