The title asks for the highest temperature in 'Seoul,' but the resolution rules explicitly specify data from the Incheon Intl Airport Station (RKSI). Incheon is located at some distance from central Seoul and is coastal, which can lead to temperature differences. Traders looking up generic Seoul weather might be misled.

May 8, 2026 - May 9, 2026, the price of '22°C or higher' surged from 4c to 42.5c (peaking at 54c), and '21°C' rose from 11.5c to 30.5c. Concurrently, '17°C' plummeted from 22c to 0.65c, and '19°C' dropped from 17.5c to 2.6c. The reason is that updated weather forecasts showed a significant warming trend for May 10, prompting the market to rapidly adjust expectations toward higher temperature ranges above 20°C.

While the rules carefully differentiate between personal attacks and policy criticisms, this introduces subjectivity. Ambiguous statements by Trump that blend policy frustration with personal animosity could lead to resolution disputes, despite relying on a consensus of credible reporting.

Betting on whether a specific politician will publicly insult a particular foreign leader (the Saudi Crown Prince) within a very narrow one-week window is highly non-standard and novelty-driven.

May 7, 2026 - May 9, 2026, the price of Option_'Yes' plunged from 15c to approximately 3c. The reason is the rapid time decay as the deadline approaches, coupled with market correction of earlier illiquidity premiums, forcing the price to reflect the reality of this highly improbable event. No significant price movements were recorded prior to this period.

From May 8, 2026 10:53 to May 8, 2026 15:00, the price of the 68-69°F option spiked from around 14c to 27.5c before steadily declining, while higher temperature options like 74-75°F dropped by >10c. This was caused by a short-term downward revision in meteorological forecast models for the projected high on May 10, which subsequently stabilized, leading to an equilibration of funds.
