Predicting the exact highest temperature in a specific city on a given date is a typical novelty market. Unless there is an extreme weather event, ordinary people do not naturally think about or predict exact temperature figures.

April 9, 2026 - April 11, 2026, prices for multiple temperature buckets experienced extreme volatility: '22°C' climbed from 26c to a peak of 47c before settling at 42.5c, '23°C or higher' surged from 8.5c to 41c then dropped back to 17.5c, while '19°C' and '20°C' plummeted to single digits. The reason is that as the resolution date nears, weather forecasting models fluctuated significantly before converging on the 21-22°C range, largely pricing out extreme highs and lows. April 9, 2026 - April 9, 2026, the price of '23°C or higher' surged from around 8.5c to 32.5c. This was driven by updated weather forecasting models revising the expected high temperature upwards, with some predicting it could reach 24°C (75°F), causing market sentiment to shift towards warmer outcomes.

While forecasting the weather for a specific city on a given day is a common daily occurrence, treating it as a financialized prediction market event is relatively niche and novel, although it is gradually becoming more popular on modern prediction platforms.

Between April 9 and April 11, 2026, the price of '15°C or higher' surged from 48.5c back up to 68c, while '14°C' also experienced high volatility, dropping from 25c to 14c before rebounding to 23.5c. This was caused by rapid revisions in weather models regarding sunshine duration and the dissipation of cold air near the target date. Between April 8 and April 9, 2026, the price of '15°C or higher' dropped from 72.5c to 61c, while the '13°C' option briefly spiked to 22c on April 8 before settling at 7.5c. This was driven by adjustments in short-term meteorological models regarding cloud cover or cooler air, which reduced the certainty of extreme high temperatures.

A divergence exists. Some mainstream weather forecasts (like direct Google search results) predict the high temperature in Munich on April 12 to be around 12°C, whereas Polymarket prices heavily heavily favor 14°C or 15°C+. This discrepancy likely arises because Wunderground, the specific resolution source, relies on microclimate models for the Munich Airport (EDDM) station which might historically record or predict higher peak temperatures than generic city-wide forecasts.

While betting on specific city temperatures is somewhat standard in prediction markets, forecasting the exact weather of a distant city on a specific date remains relatively niche and novel for the general public, making it a moderately exotic market.

April 10, 2026 - April 11, 2026, the price of the '21°C' option dropped significantly from 34.5c to 15.5c, while the '19°C' option surged from 25c to a peak of 41.5c before settling at 37c. This occurred because, nearing the resolution date, updated meteorological models ruled out higher extremes and adjusted the expected temperature down to the 19°C-20°C range. April 8, 2026 - April 9, 2026, the price of the '22°C or higher' option plummeted from 31.5c to 7.5c, and the '18°C' option dropped from 20.5c to 4c. Concurrently, both '20°C' and '21°C' options saw price increases of over 10c. This was due to the forecast track of Cyclone Vaianu becoming clearer, with mainstream forecasts zeroing in on a high of around 20°C, thereby reducing the probabilities of extreme highs and lower temperatures.

Predicting the maximum temperature of a specific city on a certain day is standard meteorological forecasting, not an outlandish topic. However, in global prediction markets, betting on the temperature in Ankara on a single date is quite niche and attracts limited broad attention.

April 10, 2026 - April 11, 2026, the price of '9°C' surged from 19.5c to a peak of 39c, as the latest weather models ruled out extreme highs, shifting the median forecast down to the 8-9°C range. April 8, 2026 - April 9, 2026, the price of '14°C or higher' plummeted from 25.5c to 2.7c, because as the target date approaches, extreme high temperatures have been ruled out by weather forecasts. April 8, 2026 - April 9, 2026, the price of '13°C' dropped sharply from 18c to 2.7c, similarly due to updated weather models eliminating the possibility of a significant warm-up. April 8, 2026 - April 9, 2026, the price of '7°C' plummeted from 17c to 4.45c, as models confirmed the minimum high temperature will be well above colder extremes.

The market currently holds high expectations for 9°C (32.5c), 10°C (33c), and even 11°C (17c). However, the latest official Wunderground forecast indicates a high of exactly 47°F (8.3°C) for April 12. This suggests that the probability of 8°C is significantly underpriced (at 11c). The market has not yet fully priced in the latest cooling trend in the forecast.

The title simply says 'tweets', but the rules explicitly exclude standard 'replies', which make up a massive portion of Musk's activity, creating a counter-intuitive pitfall. Additionally, resolution relies heavily on a specific custom tracker (xtracker), introducing technical risks of missed counts or downtime, especially for deleted posts.

This is a highly typical long-tail novelty market. Outside of prediction market degens, nobody naturally contemplates or calculates the exact number of times a specific celebrity posts on social media during a random week. It is purely for entertainment.

April 7, 2026 - April 11, 2026, the price of the '240-259' option rose from 14.5c to 23.5c, peaking at 24.5c, as actual post tracking data over time concentrated market expectations in this range. April 7, 2026 - April 11, 2026, the price of the '220-239' option rose from 9.5c to 16.5c, peaking at 17.5c, as tracking data indicated a slightly lower posting frequency than initially expected, causing a leftward shift in the distribution.
