Predicting the exact number of posts by a public figure in a specific week is a classic novelty market. Unless they are betting, general audiences rarely care about such granular data.

April 27, 2026 - April 28, 2026: The Yes price for the 60-79 option surged from 0.75c to 32.7c, and the 80-99 option surged from 14c to 55.5c. This was due to a downward adjustment in posting pace expectations for the specific time window, combined with structural distortions in the order book. April 26, 2026 - April 27, 2026: The Yes price for the 120-139 option rose from 16.5c to 32c, as early forecasting funds identified this bracket as closely aligning with his historical average output.

There are several potential pitfalls in the rules: 1) Reliance on a specific third-party tracker (xtracker) which may have lag or discrepancies; 2) The nuanced distinction between regular replies and main feed replies; 3) Deleted posts only count if they survive for ~5 minutes, increasing the risk of resolution disputes in edge cases.

This is a highly exotic and niche market. Ordinary people do not typically predict the exact number of times a billionaire will post on social media within a specific 48-hour window. It is a classic novelty betting topic.

April 28, 2026 - April 29, 2026, the price of the 40-64 range surged from 14c to 85.5c, while the 65-89 range plummeted from 67c to 15.5c. This occurred because, as the monitoring period reached roughly 83% completion, Musk's posting frequency slowed down significantly, shifting the favored outcome decisively to the 40-64 range. April 27, 2026 - April 28, 2026, the price of the 65-89 range surged from 26.5c to 64c, while the 40-64 range plummeted from 50.5c to 15.5c. This occurred because, as the monitoring period progressed, Musk's actual posting volume accumulated faster than previous pessimistic expectations, ruling out the likelihood of very low totals. April 27, 2026, as the tracking period officially started, the probabilities for <40 and 40-64 ranges continued to rise, while the 65-89 range dropped from 32.5c to 26.5c. The market further lowered its expectations for the total number of posts based on the actual posting frequency in the initial hours. April 25, 2026 - April 27, 2026, the price of the 40-64 range increased from 37.5c to 47.5c, while the 90-114 range dropped from 20c to 8.5c. This was due to the market lowering its expectations of Musk's actual recent activity levels as the tracking period approached, judging the likelihood of exceeding 90 tweets to be significantly reduced.

A key trap in the rules is that an 'announcement of resignation/removal immediately resolves to Yes, regardless of when it goes into effect.' Also, acting/interim officials are excluded, and the list of covered positions is extremely broad (ranging from the President and Congress members to State Governors and Fed officials), requiring only one to unexpectedly leave before the end of their scheduled term prior to April 30, 2026.

The novelty of this market lies in bundling hundreds of high-ranking US officials into a single probability pool, betting on whether ANY of them will abruptly leave office within an extremely short timeframe (by April 30). While official turnover is common, this packaged short-term 'death cross' style market is somewhat unusual.

April 28, 2026 - April 29, 2026, the price of Option_'Yes' plummeted from 54c to 4.5c-6.5c, likely due to market doubts about whether the resignation events qualify under the specific rules of this market, or abnormal volatility caused by illiquidity. April 27, 2026 - April 28, 2026, the price of Option_'Yes' spiked from 12c to 54c, driven by bets on the rule trigger following news of several U.S. Representatives announcing their resignations. April 24, 2026 - April 26, 2026, the price of Option_'Yes' briefly spiked from 38c to 50c, before falling back down to around 17.5c-21c. This was due to delayed market reactions or fluctuating interpretations of the rules regarding the news of several U.S. Representatives announcing their resignations, leading to significant price volatility.

Significant divergence exists. According to public information and market rules (which state resolution to Yes immediately upon announcement of a qualifying official's resignation), the event has already occurred. However, the current prediction market price (5.5c) reflects an extremely low probability, suggesting the market is either ignoring this information or holds extreme concerns that the platform might refuse to resolve as Yes for some reason.

The rules rely heavily on a specific third-party tracker (xtracker) and include a fuzzy ~5-minute capture window for deleted posts, while also distinguishing between 'main feed replies' and 'normal replies'. These technical nuances can cause discrepancies between tracked data and user observations, leading to a moderate risk of resolution disputes.

Betting on the exact number of social media posts a public figure makes in a specific week is a typical novelty behavioral market. It appears quite absurd and bizarre to the general public, even though such markets are somewhat popular in prediction circles due to Musk's high profile.

April 28, 2026 - April 29, 2026: The Yes price for the '240-259' bracket plummeted from a high of 47c to 13.5c. The reason is that as data accumulated into the second day, Musk's tweeting frequency stabilized at a lower level, causing the market to significantly downgrade its extremely high expectations for the weekly total. Earlier on April 28, 2026: Multiple brackets experienced significant price shifts. The '240-259' bracket surged from 19c to 47c, and '220-239' rose from 18c to 27c. These drastic movements reflect aggressive market recalibrations and hedging based on the actual tweeting velocity observed during the initial hours of the market period.

The rules exclude replies but note that replies recorded on the main feed will be counted by the tracker, which could cause resolution disputes. Furthermore, settlement heavily relies on a specific third-party tracker (xtracker.polymarket.com). Any tracker downtime or missed data (e.g., posts deleted before being captured) creates a risk of discrepancy with actual X data.

This is a typical novelty market for prediction platforms. For the general public, unless specifically incentivized, absolutely no one would care about or predict the exact number of tweets posted by the White House account in a single week, making it quite exotic.

Between 06:03 and 16:03 on April 28, 2026, the price of the '160-179' option surged from 38c to 58c, '180-199' surged from 23.5c to 44c, and '200+' surged from 14.5c to 45c. This suggests market expectations of a significantly higher posting frequency, likely due to breaking news or an intensive promotional campaign for a specific event. Between April 27 and April 28, 2026, lower posting brackets (e.g., 40-59, 60-79) experienced brief and anomalous price spikes (reaching ~24c) at 16:03 on April 28, before quickly retreating. This was likely due to mispricing from illiquidity or large market orders sweeping the book.
