The 2026 Atlantic hurricane season will take place over a period lasting from June 1 to November 30. This market will resolve to "Yes" if NOAA names a storm in the Atlantic between December 4, 2025, and May 31, 2026. Otherwise, this market will resolve to "No". The resolution source for this market will be NOAA’s list of named storms during the Atlantic hurricane season (https://www.nhc.noaa.gov/data/tcr/) and/or their data on individual storms. If there is a potential named storm that has not yet been classified by May 31, 2026, 11:59 PM ET, the market may remain open until June 1, 12:00 PM ET to determine if a classification was made prior to midnight.Trader consensus favors no named storm forming before the June 1 start of the 2026 Atlantic hurricane season, with "No" at a 63% implied probability, driven by the National Hurricane Center's current assessment showing no tropical cyclones or areas of interest in the basin as of April 17. Cooler-than-normal sea surface temperatures in the eastern and central tropical Atlantic—key main development region—coupled with stronger trade winds, hinder early genesis despite warmer western anomalies. Colorado State University's April 9 forecast for below-normal overall activity, citing emerging El Niño conditions that will boost vertical wind shear, has solidified this positioning. Routine NHC Tropical Weather Outlooks resume May 15, when any shifts in disturbances or model guidance could influence odds. Historically, pre-season named storms (winds ≥39 mph) are rare, with the first typically mid-June.
