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

How is ARK Market Cap calculated?

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

ARK Market Capitalization in USD = Number of ARK in supply X Price of one ARK in USD

Since the price of ARK 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 ARK or predict the price of ARK.
