The title asks for the temperature in 'Seoul', but the rules explicitly mandate using data from the 'Incheon Intl Airport Station' (RKSI). As a coastal airport, Incheon's climate can differ from downtown Seoul, creating a clear trap for those who only read the title.

Resolution relies on a specific third-party tracker rather than just visible tweets. The rules contain edge cases for replies (main feed replies count) and deleted tweets (only count if captured within ~5 mins), creating a distinct risk of discrepancy between automated tracker data and manual user counting.

Predicting the exact number of posts a public figure makes within a specific 48-hour window is highly niche and novelty-driven. It is a classic entertainment-focused market typical of prediction platforms, and not something the general public actively ponders.

April 21, 2026 - April 22, 2026, the '40-64' option's price dropped significantly from a peak of 80c down to 58.5c, while the '<40' option surged from 15.75c to 34.9c. This occurred because, entering the final 10 hours of the tracking period, Musk's posting frequency showed extreme sluggishness, presenting a significant risk that the 40-post threshold might not even be reached. April 21, 2026 - April 22, 2026, the '40-64' option peaked at 80c before settling around 73.5c, while the '<40' option continued to climb from 15.7c to 24.6c. This occurred because, entering the final 13 hours of the tracking period, Musk's posting cadence remained extremely low, significantly increasing the chances of ending up in the lowest bracket. April 21, 2026 - April 21, 2026, the price of the '40-64' option surged from 47.5c to 77c, and the '<40' option climbed from 4.35c to 15.75c, while the '65-89' option plummeted from 38.5c to 6c. This occurred because, with nearly 32 hours of the tracking period elapsed, Musk's tweet frequency further slowed, heavily favoring a final count in the 40-64 or even <40 range. April 20, 2026 - April 21, 2026, the price of the '40-64' option climbed from 34.5c to a peak of 56.5c, while the '65-89' option dropped from 43.5c to 26.5c. This occurred because, as the tracking period progressed (about 20 hours in), traders adjusted their expectations downward based on Musk's real-time activity, making the 40-64 range the clear favorite. April 18, 2026 - April 20, 2026, the price of the '40-64' option climbed from 21.5c to a peak of 43.5c, while the '65-89' option dropped from 46.5c to 36.5c. This occurred because, as the tracking period approached and began, traders adjusted their expectations downward based on Musk's real-time activity, bringing the 40-64 range into a virtual tie with the 65-89 range.

This is a highly specific novelty market. Outside of prediction market participants, the general public rarely cares about, tracks, or predicts the exact range of posts made by the official White House account in a given week.

April 21, 2026 - April 22, 2026, the price of the '140-159' option surged from 29c to 57c, while the '160-179' option crashed from 37c to 15.5c, as the actual posting pace of the White House X account slowed down approaching the expiration date, causing the market to heavily adjust expectations to the 140-159 range. April 18, 2026 - April 21, 2026, the price of the '140-159' option rose steadily from 10c to 30c, as posting frequency data indicated an increasing likelihood of the final total falling within this range. April 18, 2026 - April 19, 2026, the price of the '180-199' option dropped from 33c to 18c, as posting frequency stabilized over time, cooling expectations for an extremely high post count. April 17, 2026 - April 18, 2026, the price of the '160-179' option surged from 20.5c to over 36c, because after the actual first-day posting data was observed, the market deduced that the final total is most likely to fall in this range at the current pace. April 14, 2026 - April 17, 2026, the prices for '100-119' and '120-139' crashed from around 40c to below 10c, while '180-199' and '200+' surged by more than 15c. This is due to a notable increase in the recent posting activity of the White House X account, causing the market to adjust its expectations for the total post count significantly higher.
