It’s a testament to how massive Uber is at the moment that pulling in an additional $2.1 billion in funding is barely even noteworthy, considering how it’s just one more addition to an ever-growing list of multi-billion dollar funding rounds for the company. Uber is already the world’s most-valuable startup, currently valued at $51 billion, but this additional $2.1 billion will further solidify that position by bringing its value all the way up to $62.5 billion. One of the reasons investors are so eager to throw money at the company is that it now has a gross revenue run rate of more than $10 billion globally, although a significant chunk of that money goes to its drivers.
