About this market

Live prediction market odds for "Will US crude oil reserves fall to __ by October 30?". Above $80.99 leads at 97%. Next is Above $82.99 at 97%. $194K has traded across 35 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 11, 2026.

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 October 30, 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 October 30, 2026, and the listed value has not been reached. If data has not been released for the final week ending on October 30, 2026, by November 11, 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.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
