Look at the definition of futures in detail.
The so-called futures generally refers to futures contracts, which are standardized contracts made by futures exchanges and agreed to deliver a certain number of subject matter at a specific time and place in the future. This subject matter, also called the underlying asset, is the spot corresponding to the futures contract. This spot can be a commodity, such as copper or crude oil, a financial instrument, such as foreign exchange and bonds, or a financial indicator, such as three-month interbank offered rate or stock index.
