Weather prediction markets are relatively common on certain prediction platforms, but for the general public, forecasting the exact high temperature of a specific city (Busan, South Korea) on a specific date remains a rather niche micro-event lacking broad public discourse.

April 18, 2026 - April 19, 2026: The price of the 31°C option plummeted from 21c to 9.5c because weather forecasts shifted towards slightly higher temperature expectations (32°C-34°C), reducing the likelihood of 31°C. April 18, 2026 - April 19, 2026: The price of the 30°C option dropped from 16c to 1.45c, reflecting that it is highly unlikely for the temperature to be as low as 30°C.

April 18, 2026 - April 19, 2026, the price of the 34°C option surged from 16.5c to a peak of 37c before settling at 30.5c. This was driven by Wunderground updating its April 20 forecast, raising the expected high to 93°F (approx. 34°C). April 18, 2026 - April 19, 2026, the price of the 35°C option rose from 17c to 29c, reflecting the market's adjustments to broader upward revisions in the weather forecast. April 18, 2026 - April 19, 2026, the prices of the 32°C and 33°C options plummeted from 18c and 19c down to 1.05c and 3.05c respectively, as the updated, warmer meteorological forecasts rendered these cooler outcomes highly improbable.

Predicting the specific count of global 6.5+ earthquakes in a single week is a niche statistical forecast. It is not something the general public considers, but it isn't extremely bizarre either.

April 18, 2026 - April 19, 2026, the price of option '0' surged from 34.5c to 52c, while option '1' dropped from 48c to 31.5c. Option '2' plummeted from 42.5c to 16c, '3' from 40c to 3.5c, '4' from 37.5c to 1.35c, '5' from 33.5c to 2.05c, and '>5' from 33c to 0.7c. This is because as the observation period approaches, the anticipated probability of multiple strong earthquakes dropped significantly, and the market rapidly repriced towards the baseline of a Poisson distribution, heavily discounting multiple-earthquake options.

While the title refers broadly to Kuala Lumpur, the resolution rules strictly specify data from the Kuala Lumpur Intl Airport (WMKK) station, which is located far from the city center and may have a temperature variance. Additionally, the rule relies on whole degrees Celsius, meaning rounding methods at boundary values could cause disputes.

Predicting the exact daily maximum temperature of a specific city is highly niche and trivial. Unless one is actively participating in prediction markets or is a weather enthusiast, people rarely think about such mundane daily statistics.

Between April 20, 2026, 02:03 and April 20, 2026, 06:23, the price of the '33°C' option surged from 22c to 96.4c, while '34°C or higher' crashed to 2.85c after a brief spike, and '32°C' plummeted from 29.5c to 0.05c. This is because as the local time in Malaysia entered the afternoon, real-time weather data likely confirmed the daytime high hit 33°C but not 34°C, leading the market to price in the certainty. Between April 18, 2026, 22:58 and April 19, 2026, 15:13, the price of the '31°C' option surged from 16c to 32.5c, while the price of '33°C' dropped from 31.5c to 18c. This was due to weather forecast models upwardly revising cloud cover and precipitation probabilities as the date approached, leading to a decrease in the expected high temperature. Between 06:43 and 07:48 on April 18, 2026, the price of the '33°C' option surged from 18.5c to 31c, while the prices of '30°C' and '29°C' dropped significantly. This was driven by short-term weather model updates confirming reduced cold air activity and thinner cloud cover, leading to an upward revision of the expected daytime high temperature.
