This is a niche weather prediction market. While weather forecasting is a normal daily activity, betting on the exact daily high temperature of a specific city on a given date is not something most people naturally consider, making it moderately exotic.

April 29, 2026 - May 1, 2026, the price of the 27°C option surged from 14c to 44.5c, and the 26°C option rose from 8c to 23c, while the 29°C option plummeted from 35.5c to 7.5c, and the 28°C option dropped from 39.5c to 24.5c. This was caused by updated weather forecasts closer to the resolution date predicting lower high temperatures than previously expected, leading to a downward revision of market consensus.

While weather prediction markets are not uncommon, predicting the exact highest temperature at a specific non-US city's airport (Buenos Aires) on a given day is a relatively niche and specific topic.

April 29, 2026 - April 30, 2026, the Yes price for 24°C rose from 24.5c to 42.5c, as updated weather forecasts favored 24°C as the most likely high temperature. April 29, 2026 - April 30, 2026, the Yes price for 25°C climbed from 4.1c to 22.25c, indicating an increased probability of slightly higher temperatures. April 29, 2026 - April 30, 2026, the Yes price for 23°C dropped from 32.5c to 21c, reflecting expectations for higher actual temperatures.

The title asks for the highest temperature in Seoul, but the resolution rules explicitly specify using data from the Incheon Intl Airport Station. Incheon is coastal and its microclimate often differs from central Seoul, making this a significant rule trap.

April 30, 2026 - May 1, 2026, the price of '19°C' surged from 31.5c to 89.5c, while '20°C or higher' plummeted from 53c to 11.9c. This occurred because as May 1 arrived, actual meteorological observations heavily increased the certainty that the high temperature would lock within the 19°C range. April 29, 2026 - April 30, 2026, the price of '20°C or higher' surged from 29.5c to 55.5c, while '18°C' plummeted from 30c to 14.5c. This occurred because as May 1 approached, updated short-term weather forecasts revised the expected daytime high temperatures upwards for the Incheon area, prompting capital to shift from lower temperature brackets like 18°C to higher ones.

This is a highly specific, gossip-driven political market. Unless there is breaking legal news regarding him, the general public does not typically speculate on whether a former FBI Director will have a mugshot released within a specific week, making it quite novel and exotic.

April 29, 2026 - April 30, 2026, the price of Option_'Yes' experienced significant volatility in a very short period, surging from 12.5c to 25.5c, then dropping to 6c, rebounding to 16c, and finally stabilizing around 8.5c. This was likely due to breaking news about Comey's potential indictment or imminent surrender, which triggered speculative buying. Subsequently, market participants realized that mugshots in federal cases are rarely made public, causing the price to fall back and fluctuate to find equilibrium.

April 29, 2026 - May 1, 2026, the Yes prices for 9°C and 10°C surged significantly (from approx 22c to 34.5c, and 21.5c to 33c respectively), while the 11°C option dropped from a peak of 30.5c down to 11c. This was caused by the weather forecast becoming more precise as the date approached, narrowing the expected temperature range slightly downward to the 9-10°C bracket.
