If it were exactly the same, there would be no need for a futures market. Futures mainly represent the expectations of the industry and most relevant people for future prices, while spot is the current market price.

Short-term uncertainty combined with the leverage effect of futures will make a certain moment seem divergent. These differences are the reasons for the existence of the futures market.
