Predicting the highest temperature of a specific city on a specific date is a typical niche prediction market event. While weather forecasting is a normal part of daily life, everyday people do not typically place exact bets on a single weather station's daily high.

April 10, 2026 22:23 - April 12, 2026 04:43, the price of '17°C or higher' consistently dropped from 41c to 25.5c, as weather models solidified their predictions of rain and cooler air for Milan on April 13, reducing the likelihood of extremely high temperatures. April 10, 2026 09:23 - April 10, 2026 12:38, the price of '17°C or higher' plunged from 44c to 30.5c, then rebounded to 42c by 15:53, due to aggressive swings in short-range, high-resolution weather models regarding the exact timing of rain and cloud cover.

Between 2026-04-10 and 2026-04-12, the price of the 17°C option dropped from 29c to 9.5c, and prices for 18°C, 19°C, and 20°C also plummeted, as the latest accurate weather forecasts closer to the resolution date ruled out the possibility of reaching 17°C or higher. Between 2026-04-09 and 2026-04-11, the price of the 15°C option surged from 9.5c to 36c, and the 16°C option rose from 22.5c to 37.5c, due to the convergence of short-term weather models predicting a high temperature around 59-60°F (15-16°C). Between 2026-04-09 and 2026-04-10, the price of the 18°C option plummeted from 27.5c to 11.5c, as updated meteorological forecasts indicated the high temperature is unlikely to reach this value. Between 2026-04-09 and 2026-04-10, the price of the 19°C option plummeted from 17.5c to 3c, due to recent weather forecasts ruling out the possibility of reaching 19°C. Between 2026-04-09 and 2026-04-10, the price of the 20°C option plummeted from 17c to 3.1c, as this temperature is well above short-term forecast expectations.

April 9, 2026 - April 12, 2026, the price of the '14°C' option climbed from 15c to 36.5c, and the '13°C' option rose from 13c to 27c. This was driven by weather forecast models converging as the date approached, confirming the high will likely fall in the 13°C-15°C range. April 9, 2026 - April 12, 2026, the prices of higher temperature options like 16°C, 17°C, and '18°C or higher' plummeted (e.g., 16°C fell from 20.5c to 7.5c, and 18°C+ fell from 25c to 1.5c), as updated forecasts completely ruled out the possibility of unseasonable heat.

April 11, 2026 - April 12, 2026, the price for 32°C surged from 23c to 36.5c, and 33°C surged from 8.1c to 22.45c, while 29°C and 30°C plummeted from 15.5c and 15c to 2.55c and 5.5c respectively. This shift occurred because, as the resolution date nears, the latest meteorological models upgraded their forecasts for the April 13 high temperature, eliminating the likelihood of cooler outcomes. April 9, 2026 - April 10, 2026, the 30°C and 31°C options experienced sharp volatility. The Yes price for 30°C dropped from 27.5c to 17c, then rebounded to 38.5c on the 10th before settling at 26.5c; 31°C similarly fell from 27.5c to 15c before surging back to 31c. This was caused by shifting meteorological models debating the strength of the high-pressure ridge and cloud cover. April 9, 2026 - April 10, 2026, the Yes prices for 33°C and 34°C plummeted from highs of 18.5c and 23c respectively down to single digits (4c-5c). The reason is that as the resolution date approaches, short-term forecasts have largely ruled out extreme heat scenarios, confirming a milder weather pattern.

This is a relatively niche weather prediction market. While people casually check daily forecasts, placing exact bets on the specific daily high temperature range of a particular city is not a mainstream topic of public interest, mostly attracting weather data enthusiasts or arbitrageurs.

Between April 11, 2026, and April 12, 2026, the price of the 33°C option fluctuated between 0.315 and 0.235 before returning to 0.32, reflecting minor market jitters due to fine-tuning of meteorological models as the forecast period approaches. Between April 9, 2026, and April 10, 2026, the price of the 31°C option dropped from 33c to 17c (later recovering slightly to 21c), and the 30°C option fell from 24c to 8.5c. The reason is that as the date approaches, meteorological forecast models have converged towards higher temperatures (32°C and 33°C), leading the market to quickly price out the probability of lower temperatures.
