There is a notable location mismatch risk: the title mentions Denver, but the rules explicitly state that data from the Buckley Space Force Base Station (KBKF) in Aurora will be used. Actual high temperatures can differ slightly between these locations, potentially misleading users who only read the title.

Between April 4, 2026, and April 7, 2026, the price of the '56°F or higher' option climbed steadily from 74c and approached 99c, as approaching weather forecasts further confirmed a warm day with highs well over 56°F (expected in the 70s) for April 8, driving the market to converge completely towards this certain outcome. On April 4, 2026, Yes prices for multiple lower temperature brackets (such as '44-45°F', '46-47°F', '50-51°F') plummeted from the 8c-16.5c range down to near zero (<1c), as forecasts indicated that the possibility of these low-temperature ranges occurring had been completely ruled out.

April 6, 2026 - April 7, 2026, the price of the 78-79°F option surged from 21.5c to 38c, due to the latest short-term weather forecasts cementing this temperature range as the most likely high. April 6, 2026 - April 6, 2026, the 80-81°F option price spiked from 24.5c to 35c before retreating, as some weather models briefly predicted higher temperatures. April 5, 2026 - April 5, 2026, the price of the 82-83°F option surged from 3.3c to 19.15c, and the 78-79°F option rose from 16.5c to 28.5c, while the 74-75°F option dropped from 26c to 8c. This was caused by updated short-range weather models indicating stronger warming post-cold front, shifting market consensus away from cooler temperatures. April 4, 2026 - April 5, 2026, the 82-83°F option plummeted from 27c to 3.3c due to initial dominance of cooling forecasts associated with a weekend storm system.

Predicting the exact daily high temperature of a specific city is a relatively niche quantitative prediction market. While checking the weather is a daily routine, trading on the precise degree (to 1°C) at a specific weather station carries a certain degree of novelty and deviates from mainstream focus.

2026-04-06 to 2026-04-07, the 26°C option surged from 27.5c to 42.5c within hours before falling back to 20c, while 28°C also briefly spiked to 37c before dropping. This was caused by meteorological model updates and diverging expectations on the exact timing of showers, creating high-frequency fluctuations in high-temperature predictions between 26°C and 28°C. 2026-04-04 to 2026-04-05, the price of the 25°C option plummeted from 26c to 5c, while the 28°C option surged from 16c to 30c. This was caused by updated meteorological models significantly raising the expected high temperature for Shenzhen, leading to a rapid shift of funds from lower to higher temperature options.

From 2026-04-05 22:35 to 2026-04-07 00:35, the price of the '22°C or higher' option surged from 71.5c to 91c, as meteorological models further confirmed the influence of a warm air mass, steadily adjusting the daytime high upward. From 2026-04-04 17:20 to 2026-04-04 19:30, the price of the 19°C option spiked from 7.5c to 25c due to an update in short-term forecast models increasing the probability for this range, though it subsequently fell back. From 2026-04-04 10:50 to 2026-04-04 13:00, the price of the 22°C or higher option rose from 68.5c to 78c before slightly dropping, driven by weather forecasts leaning towards warmer conditions.
