Hurricane Polo's confirmed upgrade to hurricane status on September 21, based on NOAA Hurricane Hunters reconnaissance and satellite imagery showing a compact eye and intense eyewall, drives the 97.6% market-implied odds for strengthening from tropical storm. Warm 31°C sea-surface temperatures off southwestern Mexico and minimal wind shear enabled extreme rapid intensification, with winds surging roughly 90 knots in 24 hours to reach Category 5 strength by early September 22. Official National Hurricane Center analyses place the storm near 14.5°N 101.5°W with 160 mph sustained winds, well exceeding the Saffir-Simpson threshold. While further model runs or minor measurement revisions could theoretically alter details, the verified observational data leave little realistic scenario for reversal of the already-achieved hurricane designation.

Polo reaches hurricane strength if it attains a maximum sustained wind speed (1-minute average) of at least 74 mph, corresponding to Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale, as reported by the National Hurricane Center.
Reaching hurricane strength at any single advisory during the market's timeframe is sufficient to resolve this market to "Yes", regardless of the storm's intensity at other times.
If Polo does not reach hurricane strength by September 30, 2026, 11:59 PM ET, or dissipates before reaching hurricane strength, this market will resolve to "No". If the National Hurricane Center has not published any data by September 30, 2026, 11:59 PM ET, this market will resolve to "No".
This market will resolve based on the operational advisory data issued while the storm is active. Any revisions to the storm's peak intensity or category published later in a post-storm best-track report or Tropical Cyclone Report will not be considered for this market's resolution.
The primary resolution source for this market will be the operational advisories issued by the National Hurricane Center (https://www.nhc.noaa.gov/). If Polo is located outside the National Hurricane Center's area of responsibility, the maximum sustained wind speed reported by the responsible Regional Specialized Meteorological Center will be used.
