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

How is Omni Market Cap calculated?

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

Omni Market Capitalization in USD = Number of OMNI in supply X Price of one Omni in USD

Since the price of Omni 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 Omni or predict the price of Omni.
