How many US unicorns are profitable?

I'm curious to know, how many of the so-called "unicorns" in the United States, which are startups valued at over $1 billion, are actually turning a profit? It's a common misconception that all unicorns are financially successful, but in reality, many of them may still be burning through cash and not yet generating a positive bottom line. With the rapid growth and investment in the tech sector, it's important to understand which of these companies are truly sustainable and profitable in the long run. So, how many of these unicorns can boast a profitable business model?
