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.

April 13, 2026 - April 14, 2026, the price of '15°C or higher' surged from 40.5c to 62.5c, and '14°C' rose steadily from 22c to 32c, while '13°C' plunged from 20.5c to 5.9c, and '12°C' dropped from 20c to 2.2c. The reason is that as April 15 approaches, weather forecast models have become more accurate and indicate higher temperatures than previously expected, causing market capital to consolidate around the 14°C and 15°C or higher options. On April 13, 2026, the price of '15°C or higher' briefly plunged from 40.5c to 19.5c (before rebounding), and '12°C' dropped from 20c to 9.5c. The reason is that weather forecast models converged at the time, temporarily ruling out the possibilities of an unseasonable high above 15°C or a cooler 12°C, causing market capital to briefly consolidate around the 13°C and 14°C options.

April 13, 2026 - April 14, 2026, the price of the 32°C option surged from 16c to 32c, while the 28°C option collapsed from 21c to under 1c. This is because weather models further confirmed that the high temperature in Taipei on April 15 will be around 31-32°C, completely ruling out lower temperature possibilities. April 13, 2026, the price of the 28°C option collapsed from 21c to 7c, while the 31°C and 32°C options surged (31°C from 19c to 28.5c; 32°C from 16c to 25c). This was driven by updated short-term weather forecasting models ruling out cooler temperatures and shifting the expected high into the 31-32°C range as the target date approached.

April 13, 2026 - April 14, 2026, the price of the 18°C option climbed from 22c to 38c, as updated weather forecasts indicated an increased likelihood of this temperature range. April 13, 2026 - April 14, 2026, the price of the 16°C option plummeted from 23.5c to 3c, as the forecast temperature was revised upwards, ruling out the possibility of this lower temperature. April 13, 2026 - April 14, 2026, the price of the 14°C option plummeted from 16.5c to 0.7c, as updated weather forecast models ruled out such lower temperatures and adjusted the expected high upwards.

The rules mention using the 'Forecast' from Wunderground but provide a link to the 'History' page, which could cause literal ambiguity regarding the resolution criteria. Additionally, occasional missing data on the weather platform or the integer rounding rules when converting from Fahrenheit to Celsius might lead to edge-case disputes.

April 14, 2026 - April 14, 2026, the price of 21°C quickly rebounded from 10.5c to 33.5c, while the price of 19°C retraced from a high of 29.7c down to 14.1c. The reason is that intraday weather forecast adjustments ruled out some colder scenarios, refocusing the most likely peak temperature strictly within the 20-21°C range. April 13, 2026 - April 14, 2026, the price of 19°C surged from 8c to 19.45c (peaking at 29.7c), the price of 20°C surged from 21.5c to 43c, while the price of 22°C plummeted from 22c to 6.9c. The reason is that as the target date approaches, weather forecasts updated, lowering the expected high temperature from the 21-22°C range to the 19-20°C range. April 13, 2026 - April 13, 2026, the price of '24°C or higher' plummeted from 45c to 7.5c. The reason is that as the target date approaches, the latest weather forecasts clearly indicate a high of around 21-22°C, largely ruling out the possibility of an extreme high of 24°C or above.
