Canonical status
confidence: mediumSource status (Polymarket)
Derived status (Orrery)
Reason
Liquidity is below $1,000 — price discovery is unreliable.
The derived status is computed from the source flags plus the live YES price, so a market trading near a rail can read as PRICE-PINNED while upstream is still active. That isn't the same as resolved.

- Add to your watchlist — Home will show probability deltas since your last visit.
- Compare against sibling markets in the same event below — divergent pricing across related contracts is the cleanest tell.
Verification actions only — never trade recommendations.

Market Description
This market resolves based on when the first Atlantic hurricane forms in 2026, as classified by the U.S. National Hurricane Center (NHC). Each bracket is inclusive of both its start and end dates, evaluated in U.S. Eastern Time (ET). The bracket containing the date of the first qualifying NHC advisory will resolve "Yes", and all other brackets will resolve "No". Exactly one bracket will resolve "Yes". A tropical cyclone is considered a hurricane when it has maximum sustained winds of 74 mph or greater (Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale). A system is considered to have "formed" as a hurricane at the date and time of the first NHC public advisory that classifies a system in the Atlantic basin as a hurricane. Resolution is based on that first advisory, regardless of any later downward revision or reclassification. The sole determinant of when the hurricane formed is the issuance timestamp of that first classifying NHC advisory (evaluated in U.S. Eastern Time), not the estimated time at which the system's winds first reached 74 mph; for a system that straddles midnight between August 31 and September 1, 2026, the applicable bracket is determined solely by whether that advisory's issuance timestamp falls before or after 12:00 AM ET on September 1, 2026. The bracket "No Atlantic hurricane will form in August 2026" will resolve "Yes" if no NHC advisory classifies any Atlantic-basin system as a hurricane at any time from 12:00 AM ET on August 13, 2026 through 11:59 PM ET on August 31, 2026. The resolution source for this market is the U.S. National Hurricane Center (NHC), available here: https://www.nhc.noaa.gov/
