About this market

Context

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.

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.
