The rules exclude general replies but include 'main feed replies' and deleted tweets captured within 5 minutes. Since the market heavily relies on a specific third-party tracker (xtracker) rather than simply looking at his official X profile count, this creates potential discrepancies and moderate resolution risks.

Predicting the exact number of posts an individual makes during a specific week is highly entertaining and niche. The general public rarely thinks about or tracks such trivial data points.

Relying on a specific tracker (xtracker) introduces technical risks, such as missing quickly deleted tweets or misclassifying main-feed replies. Although X is a fallback, discrepancies between automated tracker data and manual counting often cause resolution disputes.

Betting on the exact number of tweets a specific individual makes in a random 48-hour window is a highly niche, novelty market driven by pure degency rather than conventional public interest.

April 14, 2026, the price of the <40 option surged from 1.8c to 13.45c, as Musk's tweeting volume remained extremely low, making it increasingly likely that the total will not even reach 40. April 14, 2026, the price of the 40-64 option surged from 24c to 67.5c (then slightly down to 65.5c), as Musk's tweeting volume remained sluggish over time, making this lower-frequency interval the most certain outcome. April 14, 2026, the price of the 65-89 option plummeted from 48.5c to 21.5c, because the pacing severely lagged, drastically shrinking the odds of landing in this mid-high tier. April 14, 2026, the price of the 90-114 option plummeted from 32c to 2.2c, as it became nearly mathematically impossible to reach this total in the remaining time. April 11, 2026 - April 14, 2026, the price of the 90-114 option surged from 13.5c to 32c (then fell), as the market observed a significant increase in posting frequency, pushing up volume expectations. April 11, 2026 - April 14, 2026, the price of the 40-64 option plummeted from 29c to 12.5c (then rebounded), due to the market observing an increase in his recent tweeting frequency, leading to a sharp drop in expectations for lower tweet counts. April 11, 2026 - April 14, 2026, the price of the 115-139 option surged from 2.5c to 15.45c (before collapsing to 0.15c), as his activity spiked and the market began betting on higher posting volumes, but then crashed as the pacing dropped. April 11, 2026 - April 13, 2026, the price of the 65-89 option plummeted from 50.5c to 35.5c (then rebounded), as capital rotated to higher-tier options.

Between April 13 and April 14, 2026, the price of 16°C dropped from 33.5c to 11.5c before rebounding to 19.5c, 15°C plummeted from 22c to 2.6c, 17°C rose from 32c to 48.5c before settling at 41.5c, and 18°C surged from 9.5c to 35.5c before settling at 28.5c. The reason is that as the expiration date approaches, updated weather forecasts have further confirmed an upward revision in expected high temperatures, eliminating cooler possibilities and significantly increasing the likelihood of 17°C and 18°C. Between April 13 and April 14, 2026, the price of 13°C fell from 12.5c to near zero (0.2c). The reason is that updated forecasts have confidently shifted the expected high temperature to the 16°C-18°C range, virtually eliminating the chances of cooler outcomes.

While checking the weather is a common daily activity, placing bets on the exact high temperature of a specific city on a given day is a relatively niche prediction market activity that most people do not actively ponder.

April 13, 2026 - April 14, 2026: The price for 19°C surged from 24c to a peak of 41c before falling to 36.5c, while 18°C rose from 14c to 27c. This volatility was driven by initial weather models predicting warmer highs (around 19°C), followed by subsequent cooler forecast updates that redirected capital towards the 17°C and 18°C options.

The market still prices 19°C as the frontrunner (36.5c), yet the latest official Wunderground forecasts explicitly show the expected high for April 15 has been revised down to 63°F-64°F (17°C-18°C) [2]. There is a lag in the market's reaction to the updated meteorological models, causing a significant divergence between the priced expectations and the current weather reality.

April 13, 2026 - April 14, 2026, the price of the 28°C option plunged from 34c to 18c (before slightly recovering to 23c), as weather models narrowed their forecast ranges for the peak temperature as the date approached, reducing the probability of higher extremes and shifting the center towards 26°C-27°C. April 13, 2026 - April 14, 2026, the price of the 30°C option dropped from 12.5c to around 2.5c, also due to increased certainty in weather forecasts ruling out the likelihood of unusually high temperatures.
