This market will resolve to “Yes” if the U.S. Energy Information Administration publishes a weekly figure for U.S. Ending Stocks of Crude Oil in the Strategic Petroleum Reserve less than or equal to the specified value for any week ending on or before August 28, 2026. Otherwise, this market will resolve to “No”. This market will resolve as soon as the listed value is reached, or once data has been released for the final week ending on or before August 28, 2026, and the listed value has not been reached. If data has not been released for the final week ending on or before August 28, 2026, by September 9, 2026, 11:59 PM ET, this market will resolve based on the data available at that time. The primary resolution source for this market will be the U.S. Energy Information Administration, specifically the weekly data published for the U.S. Ending Stocks of Crude Oil in the Strategic Petroleum Reserve at https://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=WCSSTUS1&f=W. Note: this market’s resolution source publishes weekly values of U.S. Ending Stocks of Crude Oil in the Strategic Petroleum Reserve in thousands of barrels. Thus, this will be the level of specificity used to resolve this market.Recent sharp drawdowns in the US Strategic Petroleum Reserve (SPR), driven by emergency releases totaling over 15 million barrels in August alone amid Middle East supply disruptions and Strait of Hormuz constraints, have pushed inventories to 289.7 million barrels as of August 21—already below 290 million and the lowest since 1982. Commercial crude stocks excluding SPR built 4.4 million barrels to 428.8 million in the week ending August 14, but trader focus remains on the SPR trajectory reflected in EIA weekly data. The August 26 release for the week ending August 21 and subsequent reports through August 28 represent the final catalysts, with market-implied odds heavily favoring levels near current readings given ongoing policy-driven releases.
