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 after market creation for any week ending on or before October 30, 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 October 30, 2026, and the listed value has not been reached. If data has not been released for the final week ending on October 30, 2026, by November 11, 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 U.S. commercial crude oil inventories, excluding the Strategic Petroleum Reserve, stood at 423.4 million barrels as of September 11, 2026, reflecting modest weekly draws amid elevated global prices near $90 per barrel for Brent. Persistent supply disruptions, including those linked to Middle East tensions, have supported stronger refinery utilization and net exports while contributing to broader inventory declines. Seasonal patterns typically favor draws through early fall before builds resume, with commercial stocks currently slightly above five-year averages. The SPR continues its policy-driven drawdown toward multi-decade lows around 285 million barrels. Weekly EIA Petroleum Status Reports, including the September 23 release, will provide key updates on whether further declines materialize by the late-October deadline amid ongoing monetary policy and demand signals.
