Will a cat 5 hurricane make US landfall during Hurricane Season 2025?

This market will resolve to "Yes" if any named tropical system makes landfall in the contiguous United States as a Category 5 hurricane between June 1 and November 30, 2025, 11:59 PM ET, as reported in official National Hurricane Center advisories (https://www.nhc.noaa.gov/archive/2025/). Otherwise, this market will resolve to "No". If any hurricane makes multiple landfalls in the contiguous United States, each landfall will be considered for the resolution of this market. For the purposes of this market, hurricane categories are defined by NOAA (https://www.nhc.noaa.gov/aboutsshws.php), and a hurricane landfall is considered to occur when the hurricane's surface center intersects with the coastline (https://www.nhc.noaa.gov/aboutgloss.shtml#LANDFALL). This market will resolve based on an initial advisory released by the NHC for whether a system has made landfall in the contiguous United States at a strength of category 5, regardless of any later retraction or analysis that may contradict the initial announcement.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
