This market will resolve to "Yes" if NOAA designates any storm in the Atlantic a hurricane 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, 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 on Polymarket reflects near-certainty at 98.1% for no Atlantic hurricane forming by May 31, driven by the National Hurricane Center's (NHC) latest assessments showing no tropical cyclones or organized disturbances across the basin as of May 14, 2026, with routine Tropical Weather Outlooks resuming May 15. Unfavorable conditions dominate, including high vertical wind shear from an emerging El Niño pattern, pervasive dry Saharan air, and despite above-average sea surface temperatures (SSTs), insufficient low-level spin or convection for development. Historically, only a handful of May hurricanes have occurred since 1851, underscoring rarity this early in the season before June 1. Realistic shifts would require a sudden tropical wave surge with rapid intensification, though model consensus indicates low risk; watch NHC updates for any changes.
