The title broadly states 'Buenos Aires', but the resolution strictly relies on the 'Minister Pistarini Intl Airport Station (SAEZ)'. The airport is outside the urban heat island, meaning temperatures can differ significantly from the city center. Additionally, relying on Wunderground's whole-degree Celsius data could pose minor rounding risks.

From 2026-04-19 17:38:18 to 2026-04-19 19:48:18, the price of '23°C or higher' surged from 32.5c to 51.5c, likely due to updated weather models predicting higher maximum temperatures for that day. From 2026-04-19 19:48:18 to 2026-04-19 21:58:18, the price of '23°C or higher' dropped back from 51.5c to 37.5c as the market adjusted its expectations, recognizing that 22°C or 21°C still hold significant probability.

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 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 15.35c. 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 even lower ranges. 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 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.

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.

The prediction market currently assigns a ~59.5% probability to '64°F or higher' and a high 32% to '62-63°F'. However, most mainstream weather forecasts indicate the high temperature on April 21 will reach 67-69°F. This divergence suggests the market might be hedging against the risk of a sudden temperature drop due to a cold front or rain, or that some traders are lagging in updating their models based on the latest forecasts.

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.
