This would be a big bump up from Uber’s most recent valuation of $3.5 billion at the time of its roughly $350 million funding round last year.
Uber did not immediately respond to VentureBeat’s request for comment.
The black-car service faces a growing pile of lawsuits from cab and insurance companies and the family who lost a 6-year-old girl in a recent accident in San Francisco, the city where Uber has its headquarters. Uber is also attracting attention from regulators of cabs.

The company has been making plenty of moves recently. Uber continues to expand into more cities, along with rolling out several new services. People can order up rides in sport-utility vehicles. Last month, Uber kickstarted an on-demand courier service. And Uber now permits you to install a child car seat for an additional fee — a good fit for families with kids.
Uber has become so widely available that Google Maps now shows people how long an Uber trip would take in comparison with other modes of transportation.
