Persistent severe drought across major U.S. cotton regions, especially the Texas High Plains, underpins the market's 100% implied probability for 55% or more of cotton acreage in drought during the week of October 6, 2026. The U.S. Drought Monitor for the period ending October 6 shows widespread D2+ conditions persisting in key production zones despite localized relief from remnants of Hurricane Polo, with prior assessments indicating 72–77% of cotton area affected by moderate or worse drought (D1+). Official monitoring from USDA, NOAA, and NASA confirms ongoing soil moisture deficits and crop stress in these areas, consistent with historical patterns of flash drought impacts on dryland cotton. A rapid shift would require substantial additional rainfall exceeding several inches over multiple weeks to meaningfully reduce D1+ coverage below the 55% threshold in the next update.
