This is a relatively niche weather derivative market. While asking 'will there be a hurricane' is common, betting specifically on 'pre-season hurricane formation before May 31' involves unusual meteorological probabilities (as the season officially starts June 1). It is more specialized and exotic than standard election or sports predictions, falling into a specific natural disaster sub-category.

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 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.

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.

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 13, 2026, the price of the 40-64 option plummeted from 29c to 16.5c. This was 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 13, 2026, the price of the 115-139 option surged from 4c to 15.45c (before settling at 10.7c), as his activity spiked and the market began betting on higher posting volumes. April 11, 2026 - April 13, 2026, the price of the 90-114 option surged from 13.5c to 26.5c, also due to the market observing a significant increase in his posting frequency.

While daily weather is widely monitored, betting on the exact integer high temperature for a specific city on a specific date falls outside standard daily concerns. It carries some novelty but remains a standard, albeit niche, category within prediction markets.

Between April 12, 2026, and April 13, 2026, the price of 18°C plummeted from 27.5c to 3.5c, and 19°C crashed from 18c to less than 1c. Simultaneously, lower temperature options like 12°C and 14°C also experienced significant drops (e.g., 14°C fell from 25c to roughly 10c). This is because, as the resolution date approaches, weather forecast models have ruled out extreme temperature scenarios, narrowly locking the expected high temperature into the 15°C-17°C range.
