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.

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.

Extreme divergence exists. Mainstream weather forecasts explicitly project the lowest temperature for Tokyo Haneda on April 15 to be around 14°C-15°C, yet the prediction market places the highest probabilities on 16°C, 17°C, 18°C, 19°C, and 20°C+. This divergence is almost certainly due to retail traders misreading 'Lowest temperature' as 'Highest temperature', causing capital to erroneously flood into options that match the expected daily highs.

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.
