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

How is Cardano Market Cap calculated?

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

Cardano Market Capitalization in USD = Number of ADA in supply X Price of one Cardano in USD

Since the price of Cardano 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 Cardano or predict the price of Cardano.
