This market will resolve to "Yes" for each listed state that has D4 (Exceptional Drought) on 0.05% or more of its land area in the US Drought Monitor release for the week of September 1, 2026. Otherwise, this market will resolve to "No". D4 area below 0.05% is treated as cartographic noise at state borders and resolves "No". States appear only during the months in which they plausibly reach D4, so this event's roster changes through the year. 40 of the 48 coterminous states are in season for September: Alabama, Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wisconsin, Wyoming. A state absent from this event is not making any claim about that state's drought — it simply has no market this week. Each USDM release covers the seven-day period ending Tuesday at 8:00 AM ET and is published the following Thursday. Resolution is based on the first published US Drought Monitor release for the listed week. Subsequent revisions will not be considered; the first published release is final. The resolution source for this market is the US Drought Monitor at droughtmonitor.unl.edu.
