This market resolves based on when the next Pacific hurricane forms, as classified by the U.S. National Hurricane Center (NHC) for the Eastern Pacific basin or the Central Pacific Hurricane Center (CPHC) for the Central Pacific basin. The bracket containing the date of the first qualifying 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). For this market, the "Pacific" comprises the Eastern Pacific basin and the Central Pacific basin as tracked by the NHC and CPHC. Systems classified as typhoons do not count. A system is considered to have "formed" as a hurricane at the date and time of the first NHC or CPHC public advisory that classifies a system in these basins 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 advisory, 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 Pacific hurricane will form in August 2026" will resolve "Yes" if no NHC or CPHC advisory classifies any Eastern Pacific or Central Pacific 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.

Compared to analyst forecasts, this market often reflects a more immediate, data-driven outlook. Analysts may incorporate long-term climate models and historical trends, while traders react quickly to real-time conditions like sea surface temperatures and wind patterns. If recent storms or shifting weather patterns emerge, this market can move faster than traditional forecasts, offering a snapshot of crowd-sourced expectations.
This market resolves around Sep 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will depend on whether a tropical cyclone reaches hurricane strength in the designated region during the market window, as reported by authoritative meteorological sources.
Signals such as updated storm watches, changes in oceanic temperatures, or shifts in atmospheric pressure patterns could move this market. Any early formation of a tropical disturbance or official hurricane warnings may cause rapid price changes. Conversely, a calm weather pattern or suppressed storm activity could lower trading odds as the resolution date approaches.
