You can check out above graph to see how the market cap of Decentraland has changed over time. The market cap value depends on the value of Decentraland on that particular day and number of Decentraland in supply at that day.

How is Decentraland Market Cap calculated?

The Decentraland Market cap is calculated using a simple formula. You can find it below:

Decentraland Market Capitalization in USD = Number of MANA in supply X Price of one Decentraland in USD

Since the price of Decentraland is highly volatile you can see the market cap going up and down a lot. Sometimes price and market cap are not linear to each other due to increase in the supply of coins in the market and stable or decrease in the price of the coin. So you can say that it's not simple to predict the market cap of Decentraland or predict the price of Decentraland.
