While weather forecasting is a standard derivative category in prediction markets, betting on the exact daily high temperature at a specific weather station in Lagos, Nigeria, on a random day is a niche topic that the general public would not typically think about or monitor.

There is a significant divergence between market pricing and mainstream forecasts. The prediction market assigns a 30% probability to 33°C and a 25.5% probability to 37°C or higher. Meanwhile, meteorological agencies (such as Google Weather and Wunderground) uniformly forecast scattered thunderstorms for Lagos on April 18, with highs between 31°C and 32°C. The market is severely overestimating the chance of extreme, rain-free high temperatures.

While checking the weather is a daily routine, predicting the exact high-temperature range for a specific city on a specific future date is not something most people think about unless prompted, making it a moderately niche prediction market topic.

April 16, 2026 - April 17, 2026: The prices of several lower-temperature options (such as 82-83°F, 80-81°F, 78-79°F) crashed by more than 10c each. For instance, 82-83°F plummeted from 20.5c to 2.5c. This is because, as the target date approaches, weather forecasts consolidated around near 90°F highs, eliminating the possibility of lower temperatures. April 16, 2026 - April 17, 2026: The price of 84-85°F dropped from 27c to 15.5c, as temperature expectations shifted even higher into the 86-89°F range.

April 16, 2026 - April 17, 2026, the price of the 25°C option surged from 14.5c to 38.5c, as the latest meteorological forecasts closer to the resolution date revised the expected high temperature upwards to around 25°C. April 16, 2026 - April 17, 2026, the price of the 23°C option plummeted from 30.5c to 12.5c, because the probability of settling at 23°C significantly decreased with the upward revision in temperature forecasts. April 16, 2026 - April 17, 2026, the price of the 24°C option rose from 20.5c to 35.5c, peaking at 37.5c, indicating that 24°C and 25°C have become the primary contested range.
