Predicting the exact daily high temperature for a specific city is a standard meteorological task, but it remains a relatively niche and somewhat novel topic for general prediction markets compared to politics or finance.

Between April 19 and April 20, 2026, the price of '64°F or higher' plummeted from a peak of 94.5c to 64.5c, while '62-63°F' surged from a low of 2.75c to 24.55c. This was caused by updated weather forecasts indicating a high chance of rain and thunderstorms on April 21, which revised expected high temperatures downward from the 67-69°F range to around 64-66°F, significantly increasing the risk of falling short of the 64°F threshold.

This is a highly niche and marginal prediction market. Ordinary audiences rarely pay attention to the exact ranking of a paid app on a specific date, making it a relatively exotic and obscure topic.

From April 17, 2026 to April 19, 2026, the price of Shadowrocket climbed from 62.5c to 93.5c, as the certainty of it maintaining the top spot increased heavily approaching the resolution date. From April 17, 2026 to April 19, 2026, the price of HotSchedules dropped from 28.5c to 6.5c, as the remaining time dwindled and its chances of overtaking the leader faded. From April 17, 2026 to April 19, 2026, several low-probability options including DualShot Recorder, Procreate Pocket, and AnkiMobile Flashcards saw their prices plummet from over 25c to below 1c, as the likelihood of these apps reaching the top was essentially ruled out with the passage of time, causing prices to return to rational levels.

Moderate rule trap exists. The title implies total tweets, but the rules explicitly exclude most replies—which typically make up a large portion of Musk's activity. Furthermore, resolution heavily relies on a bespoke Polymarket tracker (xtracker). Users checking raw tweet counts directly on X will severely misjudge the outcome.

Highly exotic. Predicting the exact number of posts by a public figure in a specific future week is a hyper-niche, entertainment-focused novelty market. The general public would almost never ponder this question naturally.

April 19, 2026 - April 20, 2026, the 280-299 option plummeted from 19.5c to 9.5c, and the 300-319 option dropped from 13.5c to 5.5c, due to lagging tweet progress and time decay, reflecting normal linear projections based on real-time counts and liquidity reversion. April 18, 2026 - April 20, 2026, the price of the 220-239 option surged from 6.5c to 20.5c, and the 200-219 option surged from 4.5c to 16.95c. The reason is that as the period progressed, Musk's actual posting frequency indicated a slower pace, prompting the market to significantly raise the probability of the final count landing in lower ranges.

April 16, 2026 - April 17, 2026, the price of 'Trust Me: The False Prophet' surged from 26c to 97.8c, due to overwhelming recent viewership data locking in its #1 spot. April 16, 2026 - April 17, 2026, the price of 'BEEF: Season 2' plummeted from 49c to 1.45c, as a competitor's massive lead eliminated its chances. April 16, 2026 - April 17, 2026, several options including 'Crooks: Season 2' crashed from around 25c to less than 1c, as the market consolidated around the definitive winner.

The market heavily relies on a specific third-party tracker (xtracker). Technical risks exist regarding how replies and deleted posts are counted, especially if the scraper experiences downtime or fails to capture a post deleted within 5 minutes, leading to discrepancies.

Predicting the exact number of social media posts a politician makes in a specific week is a highly niche, novelty-driven market. General audiences rarely think about or track this specific metric.

April 18, 2026 - April 19, 2026: The price of the 200+ option continuously surged from 4.9c to 53.15c, and 180-199 rose from 7.1c to 38.6c. This occurred because posting volume continued at an extremely high rate, forcing the market to push the expected total well above 180 posts. April 18, 2026 - April 18, 2026: The price of the 160-179 option surged from 8.5c to 39.7c as the market initially projected the pacing to land here, but it subsequently dropped back to 10.4c as even higher volumes materialized. April 17, 2026 - April 18, 2026: The 'Yes' prices for high-tier options like 160-179, 180-199, and 200+ surged significantly, while central brackets plummeted below 10c, because Trump posted at a significantly accelerated pace on the first day of the tracking period. April 14, 2026 - April 15, 2026: The 'Yes' prices for multiple outlier options plummeted from the 24-27c range down to under 5c, as the market corrected a previously massive overall probability premium, with arbitrageurs selling low-probability options.
