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.

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.

The title mentions 'Denver', but the rules strictly specify using data from the Buckley Space Force Base Station (located in Aurora). Users relying on generic Denver weather forecasts (which typically use Denver International Airport data) may face discrepancies due to microclimates and station location differences if they ignore the specific Wunderground link.

April 13, 2026 - April 14, 2026, the price of the 58-59°F option plunged from 29c to 8c, because the latest weather forecasts slightly raised the expected high temperature, indicating the cooling effect from rain would be less severe than anticipated, causing capital to shift towards the 62-63°F range. April 12, 2026 - April 13, 2026, the price of the 58-59°F option surged from 12c to 27.5c, as updated forecasts confirmed the cooling effect of expected precipitation, lowering the projected high temperature. April 12, 2026 - April 12, 2026, the price of the 66°F or higher option plunged from 39c to 5.5c, because short-term weather forecasts explicitly ruled out the possibility of extreme heat on April 14. April 12, 2026 - April 12, 2026, the price of the 60-61°F option surged from 13c to 24.5c, while the 64-65°F option plunged from 26.5c to 16c. This occurred because meteorological platforms like Wunderground updated their forecasts, revising the expected high temperature down to around 60°F.

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.

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.
