These markets track the level of the U.S. Strategic Petroleum Reserve for a specific week in 2026. They reflect how much oil is stored in emergency government reserves, which can influence energy policy decisions and market perceptions. The outcomes depend on official weekly reports released by U.S. authorities.
All markets resolve based on the U.S. Strategic Petroleum Reserve (SPR) value reported in the Weekly Petroleum Status Report for the week ending September 11, 2026. The report is released on Wednesday morning following the week in question. Each market has a specific threshold, ranging from above 280 million barrels to above 291 million barrels. If the reported SPR value exceeds the respective threshold for a given market, that market resolves to Yes; otherwise, it resolves to No. The value used for resolution is taken from Table 1 of the U.S. Petroleum Balance Sheet, specifically the row labeled “Strategic Petroleum Reserve (SPR)” under the Current Week column. All markets share this consistent methodology, with the only variation being the numerical threshold that determines the Yes outcome.
Currently, the aggregated predictions in this market reflect a different perspective than many traditional analyst forecasts regarding the US Strategic Petroleum Reserve. While some analysts predict a continued drawdown of the reserve due to geopolitical factors and domestic demand, this market suggests a broader range of potential outcomes. It's important to note that analyst forecasts are often based on specific models and assumptions, while this market represents the wisdom of the crowd, incorporating a diverse set of information and perspectives. Discrepancies can arise due to differing interpretations of economic indicators and geopolitical risks.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing different levels of the US Strategic Petroleum Reserve, and the prices of these contracts determine the implied probabilities. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of a contract reflects the market's assessment of the likelihood that the reserve will be at or above that level on the specified date. As more traders participate and new information becomes available, the prices adjust, providing a dynamic and real-time assessment of the potential future state of the reserve.
This market resolves around Sep 23, 2026, with the outcome confirmed once the official US Strategic Petroleum Reserve level for the week ending September 11, 2026, is verifiable from credible public reporting. The level will be determined by data released by the Department of Energy, and the market will settle based on which contract’s level encompasses the reported value. Traders should monitor official announcements from the Department of Energy as the resolution date approaches to stay informed about potential developments that could influence the final outcome.
Several signals and events could significantly impact this market. Unexpected geopolitical events, such as disruptions to global oil supply, could lead to a rapid increase in the perceived need to replenish the US Strategic Petroleum Reserve. Conversely, a significant increase in domestic oil production or a decrease in global demand could suggest a smaller need for reserve levels. Major policy announcements from the Biden administration regarding energy policy, or changes in OPEC+ production targets, would also likely move this market. Economic data releases indicating a recession or strong economic growth could also influence trader sentiment.
