Predicting the daily high temperature for a specific city is a typical weather betting market. While not as mainstream as political elections or financial events, it is a relatively common niche in prediction markets, making it moderately novel but not bizarre.

April 26, 2026, 01:23 - 08:58, the Yes price for the 28°C option surged from 8.5c to 99.85c, as the daytime weather in Shenzhen concluded and actual temperature logs confirmed a high of 28°C. April 26, 2026, 01:23 - 08:58, the Yes price for 29°C plummeted from 32.5c to 0.1c, and 30°C collapsed from 35.5c to 0.05c, because actual recorded temperatures fell short of these brackets. April 24, 2026, 06:03 - 09:18, the Yes price for the 30°C option surged from 10.5c to 23c. This was likely driven by updated meteorological models showing potential for brief but stronger sunshine, prompting market participants to price in a higher peak temperature. April 24, 2026, 06:03 - 09:18, the Yes price for the 27°C option plunged from 20c to 10.5c. This is directly correlated with the aforementioned upward revision in temperature expectations, as capital rotated out of lower temperature brackets.

April 24, 2026 - April 26, 2026, the price of the 62-63°F option surged from 14.5c to 49c, and the 60-61°F option rose from 20.5c to 35.5c, while 64-65°F and 58-59°F dropped. The reason is that as the resolution date arrived, official forecasts (such as Wunderground) converged, pointing clearly to a high temperature of around 62°F.

April 25, 2026 - April 26, 2026: The price of the 66-67°F option surged from 25.5c to 45.5c, as updated real-time meteorological data indicated a higher probability of temperatures reaching this warmer bracket. April 25, 2026 - April 26, 2026: The price of the 62-63°F option plummeted from 17.5c to 5.5c, as actual temperature trends largely ruled out this cooler range. Over the past few hours before that, price movements across all options had been relatively mild, with no option experiencing a change greater than 10 cents. The leading brackets (64-65°F, 62-63°F, and 66-67°F) saw slight increases, reflecting increasing confidence in the updated weather forecasts.

Predicting the highest temperature of a specific city on a precise day is a somewhat niche topic. While weather forecasts are part of daily life, ordinary people rarely bet on or deeply analyze such micro and specific daily metrics.

April 24, 2026 - April 25, 2026, the price of the '84°F or higher' option fluctuated and rose from 85c to a peak of 95.5c. This was due to weather forecasts becoming more certain about the high temperatures in the region as the resolution date approached, causing funds to concentrate in the highest temperature bucket. Before April 24, 2026, there were no significant price movements exceeding 10c. The '84°F or higher' option experienced a slight increase from 85c, reflecting the market's consolidation of funds as forecast certainty improved.

The risk is that the title says 'Denver', but the resolution rules specifically require data from the Buckley Space Force Base (KBKF) in Aurora. Temperatures can vary between the two, meaning traders relying on generic Denver weather forecasts might be misled.

From April 24 to April 26, 2026, the price of the 56-57°F option surged from 10c to 38c, and the 54-55°F option surged from 7c to 28.5c. Concurrently, the 60-61°F option plummeted from 29.5c to 4.5c, and the 62-63°F option plummeted from 26.5c to 1.15c. The reason is that as the resolution date approaches, updated weather forecasts or live data indicate the high temperature will be significantly cooler than previously expected.
