April 13, 2026 - April 14, 2026: The price of the 26°C option surged from 19c to 31.5c, the 25°C option rose from 22c to 29c, and the 24°C option fell from 31c to 14c. This was due to weather forecast models locking the expected high temperature into the 25°C-26°C range as the date approached, ruling out lower temperatures. April 13, 2026: The Yes price for 25°C surged from 22c to 36c, while the 28°C option plummeted from 17.5c to 6.5c. This was driven by updated weather forecast models which ruled out anomalous high temperatures and concentrated expectations around the 24°C-25°C range.

While daily weather forecasting is extremely common, establishing a prediction market for the exact high temperature of a specific inland city on a specific day down to the exact degree remains a somewhat niche and novelty topic.

April 13, 2026 - April 14, 2026: The price of the 22°C option steadily rose from 21.5c to a peak of 33.5c. This upward trend was driven by weather forecast models converging on 22°C as the most likely high temperature as the date approached. April 13, 2026 - April 14, 2026: The price of the 19°C option plummeted from 11.5c to 1.2c, and the 24°C option dropped from 19.5c to 9.5c. This occurred because the possibility of temperatures straying too far from the median was effectively ruled out by the highly accurate short-term meteorological forecasts.

Predicting the exact daily high temperature of a specific city is a niche daily weather forecast market. While not absurd, it is less mainstream compared to standard political or economic topics, giving it a moderate novelty factor.

April 13, 2026 - April 14, 2026, the price of the '20°C or higher' option fluctuated drastically between 33c and 56c. This was due to divergence in weather models regarding cloud cover and precipitation probability as the resolution date approached, causing market debate over whether temperatures would break 20°C. April 13, 2026, the price of the '18°C' option surged from 12c to 24.5c. This was due to updated short-term weather forecasting models indicating that cloud cover or light precipitation might suppress the maximum temperature to around 18°C.

April 13, 2026 - April 14, 2026, the price of '62-63°F' rose from 23.5c to 34c, as short-term weather forecast models slightly increased the likelihood of extreme high temperatures. April 13, 2026 - April 14, 2026, the price of '66°F or higher' plummeted from 26c to 4.75c, because as the date approaches, the probability of extreme heat has been largely ruled out by forecasts. April 13, 2026 - April 14, 2026, the price of '58-59°F' dropped from 22.5c to 16.5c, as the forecast median shifted entirely above 60°F. April 13, 2026 - April 14, 2026, the price of '56-57°F' dropped from 16.5c to 4c. This occurred because, as the date approaches, weather forecast models are trending towards higher temperatures, largely ruling out the lower temperature ranges. April 13, 2026 - April 14, 2026, the prices for '50-51°F', '52-53°F', and '54-55°F' also saw significant declines, similarly due to short-term forecasts confirming that the temperature will likely be above 55°F.

April 13, 2026 08:03 - April 13, 2026 11:18, the price of the 64-65°F option surged from 11.5c to 29.5c because weather forecast models adjusted the expected high temperatures downwards to the mid-60s earlier that day. April 13, 2026 04:48 - April 14, 2026 00:18, the price of the 70-71°F option dropped from 18c to 8c because as the expiration date approaches, multiple weather sources confirmed that temperatures are unlikely to reach 70°F, causing the market to converge towards the mid-to-upper 60s range.
