Strong El Niño conditions have driven the 2026 Atlantic hurricane season's extreme inactivity, with high wind shear and cooler sea surface temperatures suppressing intensification across the basin. As of September 20, six named storms have formed but zero reached hurricane strength on the Saffir-Simpson scale, setting a satellite-era record for the latest first hurricane and yielding just 5.1 accumulated cyclone energy units—far below the 1991–2020 average. NOAA and other forecasts anticipated a below-normal season with only 2–6 hurricanes possible, and the post-peak period offers limited windows for late development before November 30. Trader consensus favoring 1–3 hurricanes (62.5% implied probability) or zero (27%) reflects these persistent unfavorable conditions, though any unexpected model shift toward reduced shear could allow a small late-season uptick.

If there is no storm categorized as a hurricane in the Atlantic during the specified timeframe this market will resolve to "0".
A hurricane is a tropical cyclone with maximum sustained winds of 74 mph or greater (Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale), as described at https://www.nhc.noaa.gov/aboutsshws.php.
This market may resolve based on the initial NHC advisory reporting a qualifying hurricane regardless of any later advisory, retraction, best-track revision, or reanalysis that revises that storm's intensity downward. The official count will be determined by the NHC (nhc.noaa.gov) advisories.
