Recently, we talked about billionaires and how they made their money. Today, I want to talk about companies that are valued at over $1 billion dollars. 

In tech finance, a "Unicorn" is the moniker applied to private startups when they cross the supposedly mythical $1 Billion valuation level. 

Well, fairy tales are coming true more often.  

The number of Unicorns doubled in 2015 … and not just in number – but in value as well.

The chart, which only shows the 185 Unicorns that are still private companies, highlights the increasing Unicorn density since 2014.

Currently, Uber is the most valuable Unicorn, with a $66 Billion Dollar valuation.

What do you think it means?  

Are these companies a sign of a strong market, a bubble, or both?
