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 stand at 428.9 million barrels as of the August 21 EIA report, modestly above the five-year seasonal average after four consecutive weekly builds totaling over 20 million barrels. Steady domestic production near 13.8 million barrels per day, refinery crude inputs near 17.4 million barrels per day at 97% utilization, and fluctuating net imports have supported the recent accumulation despite elevated global prices. The Strategic Petroleum Reserve continues its sharp drawdown to 289.7 million barrels from ongoing emergency releases tied to Middle East supply disruptions. Weekly EIA inventory reports through mid-September, alongside any shifts in OPEC+ output or global demand response to current price levels, remain the key near-term catalysts for the market-implied odds on further declines by September 25.
