Exceptional drought (D4) by state — week of September 1, 2026Arizona

This market will resolve to "Yes" if Arizona 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". Arizona carries a market in every month of the year, so this market exists for the week valid September 1, 2026. Weeks outside that window have no Arizona market and make no claim about Arizona's drought. 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.
