This market will resolve to the bracket containing the number of coterminous US states (out of 48) with D4 percent area of 0.05% or more in the US Drought Monitor release for the week of September 8, 2026. Brackets: 0 / 1-2 / 3-4 / 5-6 / 7-9 / 10+. Exactly one bracket resolves "Yes". The count ranges over all 48 coterminous states — the 48 states excluding Alaska and Hawaii. The District of Columbia and U.S. territories are not considered. 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.

On Polymarket, this market is priced through a continuous double auction, where traders buy and sell contracts representing their beliefs about the number of states in D4 Exceptional Drought. The price of each contract reflects the market's collective probability assessment. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The more traders believe an outcome is likely, the higher the price of contracts representing that outcome will rise. Conversely, if traders believe an outcome is unlikely, the price will fall. This dynamic pricing mechanism allows the market to quickly incorporate new information and adjust probabilities accordingly, based on supply and demand for each outcome.
This market resolves around Sep 10, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will depend on the official US Drought Monitor map released by the National Drought Mitigation Center, which classifies drought conditions across the United States. The number of states designated as being in D4 (Exceptional Drought) on that map will determine the winning outcome for this market. The US Drought Monitor is a widely respected and authoritative source for drought information, ensuring a transparent and objective resolution process.
Several factors could significantly impact this market before Sep 10, 2026. Major weather events, such as prolonged heat waves or substantial rainfall, are key drivers. Updates to long-range weather forecasts from organizations like the National Oceanic and Atmospheric Administration (NOAA) will also be closely watched. Changes in water reservoir levels and snowpack in key regions could also influence trader sentiment. Additionally, government policies related to water management and drought mitigation efforts could play a role. Any news suggesting a worsening or improvement in drought conditions across the US is likely to cause shifts in the probabilities reflected in this market.
