There is a noticeable divergence between market prices and some mainstream weather forecasts. Most public forecasts (e.g., Google Weather at 88°F, KVUE at 91°F) place the high in the 88-91°F range, yet the prediction market assigns a dominant 73% probability to '92°F or higher'. This is likely due to traders adjusting for the KAUS station historically recording higher temperatures than city-wide forecasts, alongside a strong regional warming trend.

April 24, 2026 - April 25, 2026, the price of the '46-47°F' option plummeted from 34.5c to 11c because, as the resolution date approached, forecasts confirmed a cold front and rain, indicating lows well below this range. April 24, 2026, the price of the '42-43°F' option surged from 16c to 35.5c, as weather models solidified the expected temperature drop, making it a highly likely outcome. April 23, 2026, the price of the '44-45°F' option climbed from 13.5c to 36c, as earlier forecasts briefly suggested lows in this range before dropping again as the colder front was confirmed.

There is a notable risk: the title asks for 'Seoul', but the rules strictly specify data from the 'Incheon Intl Airport' (RKSI) weather station. Incheon is coastal and its temperatures often differ from downtown Seoul, creating a trap for those who only read the title.

2026-04-24 to 2026-04-25, the price of 9°C surged from around 26c to 97.5c. This occurred because, as the resolution date approached, actual meteorological observations locked in this temperature range. 2026-04-24 to 2026-04-25, the price of 8°C or below plummeted from 30c to 1.6c, as observational data ruled out the possibility of the temperature dropping to 8°C or lower.

As one of the world's largest tech giants, whether Alphabet beats earnings estimates directly dictates GOOGL's after-hours price action (a typical tradable event, often driving ~5% volatility). Furthermore, as a heavily weighted core component of the Nasdaq 100 and S&P 500, its earnings performance sets the tone for the entire tech sector and significantly impacts the short-term volatility of broader indices, making it an excellent hedging proxy.

April 23, 2026 - April 25, 2026, the price of the '70-71°F' option rose from 26c to a peak of 41c before falling to 19.5c, due to minor adjustments in weather forecasts altering expectations. April 23, 2026 - April 25, 2026, the price of the '66-67°F' option dropped from 26c to 6c, as the market heavily discounted the likelihood of temperatures dropping below 68°F closer to settlement. April 23, 2026 - April 24, 2026, the price of the '74-75°F' option plummeted from 26c to 3c, due to a significant downward shift in the expected minimum temperature.
