The title asks for Seoul's highest temperature, but the rules explicitly state that resolution is based on the 'Incheon Intl Airport Station (RKSI)'. Temperatures at Incheon Airport (coastal) often differ from central Seoul, creating a trap for traders relying on generic Seoul forecasts. Additionally, temperatures are evaluated in whole degrees Celsius without accounting for later revisions.

Moderate novelty. While weather forecasts are extremely common in daily life, betting on the exact high-temperature range (within a few degrees) for a specific city on a single day is primarily active only in niche prediction markets. It is not a mainstream trading topic for the general public or traditional investors.

Predicting the exact number of tweets a celebrity makes over a random two-day period is a classic novelty/entertainment market. The general public does not typically ponder or forecast such bizarre metrics.

April 18, 2026 15:38 to 16:43, the price of the 65-89 bracket fell from 51.5c to 43.5c, as the market adjusted expectations based on the initial posting rate after the tracking period officially started. April 16, 2026 to April 18 15:38, the price of the 65-89 bracket rose from 36.5c to 51.5c, as the market consolidated consensus that Musk's posting frequency would remain at his historical normal level of 35-45 posts per day.

UpOnly is a niche podcast specific to crypto culture. While famous within the industry, it is obscure to the general public. Predicting podcast guests falls under 'niche cultural prediction', sitting between standard election/financial markets and completely absurd novelty bets.

Second, SBF maintaining a 21.8c 'Yes' price while serving a lengthy federal prison sentence contradicts basic physical reality and corporate compliance logic.
