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 September 25, 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 September 25, 2026, and the listed value has not been reached. If data has not been released for the final week ending on September 25, 2026, by October 7, 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.US commercial crude inventories stood at 428.9 million barrels as of the week ended August 21, 2026, reflecting a modest 0.1 million barrel build that marked the fourth consecutive weekly increase and placed levels about 1% above the five-year seasonal average. Steady domestic production near 13.8 million barrels per day, refinery utilization at 97.4% of capacity, and a recent decline in both imports and exports have supported the build, while the Strategic Petroleum Reserve continued drawing down to 289.7 million barrels amid ongoing emergency releases. Weekly EIA Petroleum Status Reports through mid-September, along with any shifts in refinery demand or geopolitical supply dynamics, remain the key near-term catalysts for trader positioning ahead of the September 25 resolution.
