While weather forecasting is an everyday necessity, betting on the exact daily high temperature of a specific city in a prediction market is a somewhat niche and novelty market, diverging from traditional macroeconomic or political forecasting.

May 07, 2026 - May 09, 2026, Chelsea's Yes price rebounded significantly from 15c to 30c, as the market corrected its expected win probabilities for the final after brief volatility. Apr 26, 2026 - Apr 27, 2026, Chelsea's Yes price surged from 18.5c to 29c, as they secured their spot in the final, leading to a significant repricing of their championship odds by the market. Apr 03, 2026 - Apr 06, 2026, Manchester City's price surged from 27c to 63.5c, as they advanced to the semi-finals and established themselves as the overwhelming favorites to win the tournament. Mar 18, 2026 - Mar 24, 2026, the market entered a high consolidation phase, with no major option showing price volatility exceeding 3c in the last week. This suggests the Quarter-Final landscape is set, and the market is waiting for match days without any odds-shifting injuries or breaking news. Mar 06, 2026 - Mar 09, 2026, West Ham United's price surged from 3.8c to 14.35c, driven by a key knockout victory or a highly favorable draw. Mar 05, 2026 - Mar 06, 2026, Leeds United AFC's price skyrocketed from 4c to 14.7c, reflecting a drastic repricing due to recent match results.

May 8, 2026 - May 9, 2026: The price of the 82-83°F option rose from 17c to 38c, while the 76-77°F option plummeted from 15c to 3c. This occurred because, as the expiration date nears, weather models revised the high temperature forecast upwards and converged on the 82-84°F range, causing the market to price out lower temperature possibilities. May 8, 2026: The prices of the 74-75°F, 84-85°F, and 88-89°F options plummeted by more than 10c. This happened as weather forecast models converged on a narrower temperature range (around 80°F) heading into the weekend, effectively ruling out extreme deviations.

Predicting the daily high temperature for a specific city is a somewhat niche but standard 'weather' category in prediction markets. It is moderately novel, as the general public does not typically bet on specific daily temperatures, but it is not extremely bizarre.

May 9, 2026 - May 10, 2026, the price of the 32°C option surged from 44c to 68.5c, and the 31°C option plummeted from 36c to near 0c. The reason is the approaching resolution date and updated weather forecasts confirming a high certainty of temperatures reaching 32°C. May 8, 2026 - May 9, 2026, the price of the 32°C option surged from 22.5c to 45.5c, the 33°C option rose from 11c to 26.5c, while the 31°C option fell from 33.5c to around 18.5c. The reason is that updated forecasts closer to the date indicate partly sunny conditions between showers, leading to a slight upward revision of the expected peak temperature. May 8, 2026 - May 8, 2026, the price of the 31°C option surged from 22c to 33.5c, and the 32°C option jumped from 22.5c to 33c. The reason is that weather forecasts indicated a high likelihood of peak temperatures settling in the 31-32°C range due to expected thunderstorms, thereby reducing the probability of extreme high temperatures.

Between May 8 and May 9, 2026, the prices of several options such as 50-51°F and 56-57°F experienced violent fluctuations of more than 10 cents (e.g., 56-57°F jumped from 3.5c to 18.2c, and 50-51°F dropped from 24.5c to 13.5c). This was due to fine-tuning in short-term weather models which triggered a market reassessment of the exact timing of the cold front. Between 04:38 and 05:43 on May 8, 2026, the 'Yes' prices for almost all options outside the 50-55°F range (such as 48-49°F, 56-57°F, and 62°F+) plummeted by more than 10 cents. This was caused by meteorological models reaching a strong consensus for the May 10 forecast as the date approached, eliminating the likelihood of extreme temperatures.
