The exact word-matching rules are strict (plurals, possessives, and compound words count, but not other forms), and some options require specific frequency thresholds (e.g., 5+ times). This creates a high risk of resolution disputes based on minor transcript discrepancies.

This is a classic 'political speech bingo' market. Predicting the exact vocabulary a politician will use in a single interview (including obscure terms like 'Bottom of the Sea') is a highly niche, novelty, and entertainment-driven prediction.

The Yes price for highly frequent terms (like Biden, Inflation) on Polymarket is only 0.415, severely underestimating the probability of Trump mentioning these signature political and economic terms. Mainstream media and historical text analyses consistently identify these as his core talking 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 11, 2026 - April 14, 2026, the price of the 90-114 option surged from 13.5c to 32c (then fell to 22.5c), 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 (rebounding to 20.5c), 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 settling at 8.2c), as his activity spiked and the market began betting on higher posting volumes. April 11, 2026 - April 13, 2026, the price of the 65-89 option plummeted from 50.5c to 35.5c (rebounding to 44.5c), as capital rotated to higher-tier options.

Between April 14, 2026 05:53 and 09:08, the price of '18°C or below' surged from 78.4c to 99.5c. This occurred because Beijing time entered the evening, and the daily highest temperature was finalized at or below 18°C, eliminating all uncertainty. Between April 14, 2026 00:28 and 03:43, the price of '18°C or below' skyrocketed vertically from roughly 3.4c to 64.2c, while '20°C' and '21°C' collapsed from 32c and 28.5c to single digits, respectively. This was driven by actual weather observations on settlement day showing significantly lower temperatures than initially expected, confirming a cold trend. Between April 12 and April 13, 2026, the price of '20°C' rose from about 24.5c to a peak of 35c before dropping to 19c, driven by expectation shifts due to real-time weather data updates as the settlement date approached. Between April 12 and April 13, 2026, the price of '18°C or below' plummeted from 38c to around 9c as the likelihood of actual temperatures exceeding this threshold increased significantly. Between April 12 and April 13, 2026, the price of '23°C' crashed from 25.5c to around 3.4c, as the probability of reaching 23°C was disproven by the market over time.

Predicting the specific temperature of a certain city is a common category in prediction markets, but for most non-locals or non-meteorology enthusiasts, thinking about such highly specific figures is rare in daily life.

April 13, 2026 - April 14, 2026, the price of the 12°C option surged from 1.85c to 63.5c. The reason is that as time progressed, actual observation data got closer to 12°C, prompting the market to rapidly adjust its expectations. April 13, 2026 - April 14, 2026, the price of the 13°C option surged from 0.9c to 39.25c. This is because temperatures might exceed expectations, making 13°C a strong contender. April 13, 2026 - April 14, 2026, the price of the 10°C option plummeted from 49.5c to 0.05c. The reason is that actual temperatures have clearly surpassed 10°C, rendering this option obsolete. April 13, 2026 - April 14, 2026, the price of the 11°C option plummeted from 49.5c to 0.05c, as actual temperatures have already exceeded 11°C. April 12, 2026 - April 13, 2026, the price of the 9°C option surged from 26.5c to 43.5c, while options like 8°C, 11°C, 12°C, and 7°C plummeted by 15-25c. This is because, as the settlement date nears, forecasts show an overwhelming probability of the high temperature landing in the 9-10°C range, rapidly cooling market expectations for non-core ranges. April 12, 2026 - April 12, 2026, the prices of edge options like 8°C, 14°C, 15°C, and 16°C or higher plummeted by more than 10c each. This is because as the target date approaches, weather forecasts are converging to the 9°C-12°C range, significantly dropping the probability of extreme temperatures.
