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.

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.

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 28, 2026 - April 29, 2026: The Yes price for the 80-99 option dropped from 55.5c to 32.5c, and the 120-139 option dropped from 45c to 25.5c. This was due to a recalibration of extreme expectations as the actual posting data from the first day became available. 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.

The rules explicitly state resolution is based on the US Eastern Time (ET) calendar date. Since China Standard Time is 12 hours ahead of ET, a visit's local date in China could easily misalign with the ET date (e.g., landing in the morning in Beijing means it's still the previous day in ET), making this a major time-zone trap. Additionally, defining 'maritime territory' could be ambiguous in disputed waters.

There is a significant divergence in market pricing. According to credible mainstream media, Trump is scheduled to visit China on May 14-15. However, the prediction market currently prices 'May 16' at 24c, which is much higher than the actual likely arrival dates (May 13 and May 14 ET). This could be due to traders miscalculating the time zone difference or being misled by inaccurate alternative information sources.

Betting on the arrest of a specific former government official is a niche political market. However, because Comey was just indicted again by the DOJ with an active arrest warrant, it is a highly publicized current event, making it only moderately exotic.

April 25, 2026 - April 28, 2026, the price of Option_'Yes' surged to 68c. This was driven by breaking news on April 28 that the DOJ indicted Comey for a second time and officially issued an arrest warrant, making his arrest or surrender before May 15 imminent.

Significant divergence exists. The current market price (68c) heavily underestimates the likelihood of an arrest. Mainstream media has confirmed that a federal arrest warrant was officially issued today (April 28). Under these circumstances, Comey being detained or voluntarily surrendering (both qualifying as 'Yes') is merely a procedural formality and will undoubtedly occur before May 15. The market is likely lagging and has not fully priced in the issuance of the active warrant.
