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.

From April 14, 2026 to 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.

The market heavily relies on a specific third-party tracker (xtracker). Technical risks exist regarding how replies and deleted posts are counted, especially if the scraper experiences downtime or fails to capture a post deleted within 5 minutes, leading to discrepancies.

Predicting the exact number of social media posts a politician makes in a specific week is a highly niche, novelty-driven market. General audiences rarely think about or track this specific metric.

April 14, 2026 - April 15, 2026: The 'Yes' prices for multiple outlier options (such as <20, 40-59, 140-159, 160-179, and 200+) plummeted from the 24-27c range down to under 5c. This occurred because the market corrected a previously massive overall probability premium, with arbitrageurs aggressively selling low-probability options to restore a rational distribution.

Moderate rule trap exists. The title implies total tweets, but the rules explicitly exclude most replies—which typically make up a large portion of Musk's activity. Furthermore, resolution heavily relies on a bespoke Polymarket tracker (xtracker). Users checking raw tweet counts directly on X will severely misjudge the outcome.

Highly exotic. Predicting the exact number of posts by a public figure in a specific future week is a hyper-niche, entertainment-focused novelty market. The general public would almost never ponder this question naturally.

Betting on the daily high temperature of a specific city is a typical daily novelty market on prediction platforms. While not a mainstream financial asset, it is common among prediction market users, giving it a moderate novelty score.

April 16, 2026 - April 17, 2026, the price of the 10°C option dropped from 32c to 16c due to downward revisions in weather forecast temperatures. April 16, 2026 - April 17, 2026, the price of the 7°C option rose from 4.5c to 16.5c due to downward revisions in weather forecast temperatures. April 16, 2026 - April 17, 2026, the price of the 12°C option dropped from 21c to 2.3c due to downward revisions in weather forecast temperatures. April 16, 2026 - April 17, 2026, the price of the 11°C option dropped from 19c to 7.5c due to downward revisions in weather forecast temperatures.

Predicting the exact number of solar or geomagnetic storms within a specific week is a highly niche and exotic topic for the general public, mostly appealing to geeks, science enthusiasts, or professional meteorologists.

April 14, 2026 - April 17, 2026, the '<3' option surged from 38c to 77c before settling at 72c, while options like '3' and '7' also experienced intense fluctuations. The reason is that as settlement approaches, the market continuously adjusted expectations based on the latest space weather data, with illiquidity amplifying price swings. April 14, 2026 - April 15, 2026, the '<3' option bounced back from 36c to 50c, while '7' and '8+' fluctuated between 20c and 26c, as the market fiercely debated whether the final event count would break into the higher tiers as expiration nears, exacerbated by massive illiquidity. April 14, 2026 00:00 - April 14, 2026 17:00, the price of the '<3' option fell from 51c to 31c, while the '3' option fell from 38.15c to 30c, the '7' option fell from 35.5c to 22.5c, and the '8+' option fell from 38.15c to 20.55c, as the market continuously adjusted expectations based on the latest space weather forecasts a few days before expiration, with illiquidity causing severe price fluctuations. April 12, 2026 - April 13, 2026, the price of the '<3' option surged from 12.5c to over 82c, while the '8+' option violently fluctuated between 10c and 42c, as the market aggressively corrected its early-week forecasts, likely reacting to updated space weather data. April 11, 2026 - April 12, 2026, prices for options 4, 5, 6, 7, and 8+ plummeted from the 40-50c range down to the 6-21c range. The reason is market participants stepping in to correct the absurdly high prices caused by extreme illiquidity and initial mispricing, bringing them closer to a realistic probability distribution.
