The Strategic Petroleum Reserve (SPR) is the U.S. government's emergency stockpile of crude oil stored in underground salt caverns. This event tracks the SPR inventory level reported for the week ending July 10, 2026, as published by the Energy Information Administration in their Weekly Petroleum Status Report.
Resolution is determined by the Strategic Petroleum Reserve (SPR) value reported in Table 1 of the U.S. Petroleum Balance Sheet for the week ending July 10, 2026, as published in the Weekly Petroleum Status Report released on Wednesday morning following that week. Each market outcome corresponds to a specific SPR threshold: the market resolves to Yes if the reported SPR level exceeds the threshold stated in that outcome (314, 316, 318, 320, 322, 324, or 326 million barrels). The resolution uses the Current Week column value from the SPR row of the official petroleum balance sheet. All outcomes reference the same authoritative data source and measurement methodology, allowing traders to express views on the precise SPR inventory level across a range of potential values.
Prediction market odds often diverge from traditional analyst forecasts because they aggregate real-money bets from diverse participants rather than relying on a single expert view. This market embeds forward-looking expectations from traders who have direct financial incentive to forecast accurately. While energy analysts may publish point estimates or ranges based on historical trends and policy analysis, this market reflects dynamic, continuously updated probability distributions. Comparing the two reveals whether professional consensus aligns with market-implied odds—discrepancies can signal either underappreciated risks or overconfidence in one camp. Monitoring both sources provides a richer picture of SPR level expectations heading into the resolution week.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different SPR level outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, and the current bid-ask spread reflects the market's uncertainty around the final SPR reading. Prices range from 0 to 100 cents per share, with higher prices indicating greater perceived likelihood. Traders profit by correctly predicting which range the SPR level will fall into by the resolution date, and the platform's matching engine continuously updates prices as new orders arrive and existing positions are closed.
This market resolves around Jul 22, 2026, once the official SPR level for the week ending July 10, 2026 becomes available and verifiable from credible public sources. The outcome is determined by comparing the actual reported inventory figure against the predefined ranges offered in the market. Traders holding shares in the correct outcome range receive their payout, while incorrect positions expire worthless. The resolution process is automated once data is confirmed, ensuring all participants receive timely settlement.
Several catalysts could shift odds significantly before resolution. Geopolitical tensions affecting global oil supply, unexpected refinery outages, or major policy announcements regarding SPR releases or purchases would likely trigger sharp repricing. Weekly petroleum inventory reports from the Energy Information Administration provide real-time signals about storage trends and can confirm or contradict market expectations. Seasonal demand patterns, hurricane activity in the Gulf of Mexico, and international crude production changes also influence SPR levels. Additionally, statements from energy officials or changes in government energy strategy could prompt rapid position adjustments as traders reassess probabilities.
