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 October 13, 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 October: 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. The first published release is final, and that publication is the revisions cutoff; subsequent revisions will not be considered. In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market. Revisions remain subject to the cutoff above. The only exception is a correction of a clearly erroneous print under the preceding paragraph, which will be used even if published after the cutoff. If the US Drought Monitor has not been published by 11:59 PM ET on the day following the scheduled publication date, this market will resolve to "No". The resolution source for this market is the US Drought Monitor at droughtmonitor.unl.edu.

Currently, prediction market odds offer a unique perspective compared to traditional analyst forecasts regarding the potential for widespread drought. While expert meteorological predictions provide valuable insights, this market aggregates the wisdom of the crowd, reflecting a broader range of information and perspectives. Discrepancies between the two may arise due to differing methodologies, data sources, or the incorporation of subjective factors. It's important to consider both sources when evaluating the probability of significant drought conditions in 2026.
On Polymarket, this market is priced using a continuous double auction. Traders buy and sell shares representing their belief in the likelihood of Exceptional drought (D4) occurring in any US state during the week of October 13, 2026. The price of these shares fluctuates based on supply and demand, effectively creating a real-time probability estimate. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current price reflects the collective assessment of all participants trading in this market, and can change rapidly with new information or shifts in sentiment.
This market resolves around Oct 15, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the US Drought Monitor will be used to determine if Exceptional drought (D4) conditions are present in any US state during the week of October 13, 2026. If D4 conditions are reported, the market will resolve positively; otherwise, it will resolve negatively. The resolution will be based on official data released by the relevant authorities and publicly available information.
Several factors could significantly influence trading activity in this market. Major weather patterns like El Niño or La Niña developments, seasonal climate outlooks released by organizations like NOAA, and any unexpected shifts in long-range forecasts are all potential catalysts. Additionally, reports of unusually dry conditions or water restrictions in key agricultural regions could drive increased trading volume and price fluctuations. Finally, any significant news regarding water management policies or infrastructure projects could also impact trader sentiment and move this market.
