This prediction market topic focuses on whether a named storm will form in the Atlantic basin before the official start of the 2026 hurricane season. The Atlantic hurricane season is formally defined by the National Oceanic and Atmospheric Administration (NOAA) as running from June 1 to November 30 each year. This market specifically resolves based on whether NOAA names a tropical or subtropical storm in the Atlantic between December 4, 2025, and May 31, 2026. A 'named storm' refers to any system that reaches tropical storm strength, with sustained winds of 39 miles per hour or higher, prompting the National Hurricane Center to assign it a name from the predetermined annual list. The resolution will be determined using NOAA's official Tropical Cyclone Reports and storm data. The question of pre-season storm formation has gained significant attention in recent years due to changing climate patterns and the increasing frequency of early-season activity, making it a subject of both scientific study and public interest. Meteorologists, insurance companies, and coastal communities closely monitor these early developments as potential indicators of an active season ahead. The specific date range from December 4, 2025, covers the period immediately following the previous season and the months leading up to the official start, capturing any out-of-season tropical activity.

Historical Context

The occurrence of named storms before the official June 1 start date is not unprecedented but has become notably more frequent in recent decades. Historically, the Atlantic hurricane season was considered to run from June through November, but recorded activity outside this window dates back to the 19th century. A significant precedent was set in 2016 when Hurricane Alex formed in January, becoming the first January hurricane since 1938. The 2020 season was particularly remarkable, beginning with Tropical Storms Arthur and Bertha forming in May, marking the sixth consecutive year with a pre-season named storm. This trend has prompted scientific discussion about whether the official definition of the hurricane season should be revised. The 2023 season continued this pattern with an unnamed subtropical storm in January, highlighting the challenges of off-season monitoring. Climate studies suggest that warming ocean temperatures may be contributing to a lengthening of the season, with a greater potential for tropical development in May and even late April. The specific resolution window for this market, starting December 4, 2025, follows the extremely active 2025 season, which itself may influence oceanic and atmospheric conditions heading into the off-season.
