With Uber still private, people don't understand just how profitable it is, says Robert Peck, internet equity analyst at SunTrust Robinson Humphrey.
Though it's just six years old, Uber is already making money in its "mature" markets, Peck told CNBC's "Squawk Alley." The rumors of fast growth have left investors chomping at the bit to get in on the company, as initial public offerings have stagnated since the middle of last year.
"What you've seen is some of the private markets be able to capitalize on the growth as they come later and later for IPOs," Peck said Tuesday. "It will be interesting to see, as the IPO winter sort of thaws here, as companies start to ramp up going forward, if investors will get a shot at those."
