Description

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.

Frequently asked questions

The US crude oil reserves market dashboard on Polymarket tracks real-time odds and trading activity around whether American crude stockpiles will decline to a specific threshold by late August. Traders buy and sell shares reflecting their conviction on reserve levels, with the price of each outcome displayed as a percentage probability. The dashboard shows current odds, historical price movement, and volume of $66,257 in total trading activity. This market aggregates sentiment from participants who monitor energy policy, production trends, and geopolitical factors affecting domestic oil supply. Updated continuously, it serves as a live gauge of market expectations for US energy reserves over the coming months.

Prediction market odds often diverge from traditional analyst forecasts because they reflect real-money incentives and crowdsourced judgment rather than institutional models alone. While energy analysts may rely on production data, refinery utilization, and policy announcements, traders in this market synthesize those signals plus geopolitical risk, supply shocks, and demand swings into a single probability. Prediction markets tend to update faster than consensus forecasts when new information emerges. Comparing the current odds here to published energy agency reports and oil market commentary can reveal where the crowd sees upside or downside risk that mainstream analysis may have underweighted.

On Polymarket, this market is priced through an automated market maker that allows traders to buy or sell shares of each outcome continuously. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each share reflects the probability assigned by the market; a share trading at 0.65 implies a 65% chance of that outcome occurring. Traders profit by buying low and selling high, or by correctly predicting which outcome will materialize. Fees are deducted from trades, and the final payout is determined once the event resolves. This mechanism ensures prices adjust in real time as new information and trader conviction flow into the market.

This market resolves around Sep 8, 2026, at which point the outcome is confirmed based on verified data about US crude oil reserve levels. The result will be determined by credible public reporting from energy authorities and official sources that track domestic stockpiles. Once the event is verifiable and the reserve figure is established, the market settles automatically and traders receive payouts according to which outcome occurred. Until that date, odds will fluctuate as traders reassess the likelihood based on production reports, policy changes, and market developments.

Several catalysts could shift odds significantly before resolution. Weekly inventory reports from energy agencies often trigger sharp price moves if reserves rise or fall unexpectedly. Geopolitical tensions affecting global oil supply, OPEC production decisions, and US domestic drilling activity all influence reserve levels. Refinery maintenance schedules and seasonal demand patterns also matter. Policy announcements—such as changes to the Strategic Petroleum Reserve or export rules—can reshape expectations overnight. Economic data affecting fuel consumption and recession risk will sway trader conviction. Traders monitor these signals continuously, repricing the market as new information arrives and uncertainty resolves.
