Crude oil futures were negative for a single day (if my memory serves me correctly) a little over a year ago. The holder of the contract at its expiration has to make arrangements to actually receive it -- you were getting paid to take oil that was very hard to move and very hard to do anything with at the height of the pandemic. Obviously, the future where nearly all consumption stopped and everybody stayed in their house for the next 3-5 years didn't happen. The opposite did, and the pricing reflects that.
