The complexity of the rules lies in its reliance on a specific tracker (Polymarket's xtracker) and specific types of tweets. Replies are excluded unless they appear on the main feed. Furthermore, deleted tweets count if they survive long enough (~5 mins) to be captured. These technical details could create discrepancies compared to manual observation on X.

Predicting the exact number of tweets a person posts in a week is a highly niche and entertainment-driven market. Typically, the general public or traditional financial markets do not care about such highly specific and random behavioral data.

April 14, 2026 - April 14, 2026, the price of the 300-319 option surged from 52.9c to 74.8c, as with only hours left until resolution, the total post count is highly converging on this range, strongly boosting market confidence. April 14, 2026 - April 14, 2026, the price of the 320-339 option plummeted from 41.85c to 9.25c, as the likelihood of reaching this higher bracket significantly dropped with the passing time. April 13, 2026 - April 14, 2026, the price of the 320-339 option rose from 27.95c to 41.85c, as continued posting close to settlement temporarily made this bracket a likely final landing spot. April 13, 2026 - April 13, 2026, the price of the 300-319 option plummeted from 57.9c to 30.5c, as slight shifts in posting speed increased the likelihood of higher brackets, splitting the probabilities. April 13, 2026 - April 13, 2026, the price of the 340-359 option fell from 26.95c to 8.95c (and later down to 2.1c), as the remaining time to achieve this high count dwindled, cooling market expectations. April 12, 2026 - April 13, 2026, the price of the 340-359 option surged from 0.25c to 26.95c before falling back to 17.95c, driven by a massive spike in posting frequency pricing in higher totals, though expectations later converged. April 12, 2026 - April 13, 2026, the price of the 360-379 option surged from 0.15c to 15.55c before falling to 7.45c, as surging post volumes prompted bets on an extremely high final count, followed by a rational pullback. April 12, 2026 - April 13, 2026, the price of the 280-299 option plummeted from 33.0c to 0.55c before slightly bouncing to 4.2c (and later to 12c), because the overly fast posting pace led actual data to quickly blow past or approach breaking this bracket.

The title simply says 'tweets', but the rules explicitly exclude standard 'replies', which make up a massive portion of Musk's activity, creating a counter-intuitive pitfall. Additionally, resolution relies heavily on a specific custom tracker (xtracker), introducing technical risks of missed counts or downtime, especially for deleted posts.

This is a highly typical long-tail novelty market. Outside of prediction market degens, nobody naturally contemplates or calculates the exact number of times a specific celebrity posts on social media during a random week. It is purely for entertainment.

April 11, 2026 - April 14, 2026, the price of the '320-339' option surged from 3.1c to 26.2c, as the actual high posting speed made it the highest probability target via linear extrapolation. April 11, 2026 - April 14, 2026, the price of the '300-319' option surged from 5.5c to 23.5c, as the posting speed stabilized at a high level, turning it into a core favorite. April 11, 2026 - April 14, 2026, the price of the '340-359' option surged from 1.6c to 17.6c, as significantly increased posting velocity shifted market expectations upward. April 12, 2026 - April 14, 2026, the price of the '280-299' option plummeted from 21.5c to 7.6c, because accelerating volumes meant the total will likely easily surpass this bracket. April 11, 2026 - April 14, 2026, the price of the '260-279' option plummeted from 21.5c to 2.2c, as the high-frequency weekend posting confirmed this bracket would be massively breached. April 11, 2026 - April 13, 2026, the price of the '360-379' option surged from 0.6c to 13.8c, as some bettors speculated on an extreme posting spree.

Moderate risk exists. Resolution relies on a specific third-party tracker (xtracker) and involves nuanced rules (e.g., specific exceptions for main feed replies, and counting deleted tweets if captured within 5 mins). This can cause discrepancies between the tracker data and native user observations on X.

Highly exotic. Betting on the exact tweet volume of a public figure over a random 48-hour window is a pure novelty market tailored for crypto-native speculation, rarely seen in traditional or serious forecasting.

There is a severe divergence between market prices and meteorological forecasts. The Yes prices for '78°F or higher' and other high-temperature options are abnormally high, while the most accurate forecast range '60-61°F' is priced at only 3.5c. This is likely due to traders confusing the daily High with the daily Low, mistakenly betting based on the daytime heatwave forecast.

Predicting the exact daily high temperature for a specific city is a niche but standard topic in prediction markets. While common for specialized bettors, the general public rarely speculates on short-term exact daily temperature figures unless an extreme weather event is occurring.

On April 13, 2026, the Yes price for the 31°C option climbed rapidly from 26.5c to 36.5c (+10c), while extreme high (≥36°C) and lower temperature options were further sold off. This shift occurred as weather forecast models converged with the approaching date, significantly increasing the probability of a high temperature centered around 31°C.
