This prediction market topic asks whether a hurricane with maximum sustained winds of at least 157 miles per hour will make landfall on the coastline of the conterminous United States before the end of 2026. The question is based on the Saffir-Simpson Hurricane Wind Scale, where Category 5 represents the most intense storms. Landfall is specifically defined as when the storm's surface center crosses the coastline, not merely when its outer bands or storm surge affect an area. The official data from the National Hurricane Center, a division of the National Oceanic and Atmospheric Administration, will be used to resolve the market. Interest in this topic stems from the intersection of meteorology, climate science, and risk assessment. While Category 5 hurricanes are rare at landfall, their potential for catastrophic damage makes their probability a critical factor for insurance markets, emergency management, and long-term infrastructure planning. Recent hurricane seasons, including the extremely active 2020 season and Hurricane Ian in 2022, have kept public and scientific attention focused on the potential for high-intensity landfalls. Research into the influence of climate change on hurricane intensity adds a layer of long-term significance to the question of whether such an extreme event will occur within this specific timeframe.

Historical Context

The historical record of Category 5 hurricane landfalls in the United States is exceptionally short. Since reliable records began in the mid-19th century, only four storms have made landfall on the U.S. mainland at that intensity. The Great Labor Day Hurricane struck the Florida Keys in 1935 with estimated winds of 185 mph. Hurricane Camille came ashore in Mississippi in 1969 with 175 mph winds. Hurricane Andrew hit South Florida in 1992 as a Category 5 with 165 mph winds, though a post-analysis reclassification upgraded it from a Category 4 years later. Most recently, Hurricane Michael made landfall in the Florida Panhandle in 2018 with 160 mph winds, and was upgraded to Category 5 status in post-storm analysis. This pattern shows these events are rare, occurring decades apart, but have affected different coastlines from the Gulf to the Atlantic. Several other storms, like Hurricane Katrina in 2005 and Hurricane Ian in 2022, reached Category 5 strength over water but weakened slightly before landfall, resulting in catastrophic Category 4 impacts. This history sets a baseline for the extreme rarity that the prediction market is attempting to quantify.
