$20bn of rides were booked through Uber in 2016

"The ride-hailing giant more than doubled gross bookings in 2016 to $20 billion, according to financial information Uber shared with Bloomberg. Net revenue was $6.5 billion, while adjusted net losses were $2.8 billion, excluding the China business, which it sold last summer.

Uber’s business is massive and getting bigger. In the last three months of 2016, gross bookings increased 28 percent from the previous quarter to $6.9 billion. The company generated $2.9 billion in revenue, a 74 percent increase from the third quarter. Losses rose 6.1 percent over the same period to $991 million.
While the rate of sales growth compared with losses is encouraging, Uber is still losing a significant sum, said Evan Rawley, a business professor at Columbia University. “That’s a lot of cash to burn in a quarter,” he said. Jeff Jones, the company’s president of ridesharing who resigned last month, previously joked to staff that he joined Uber expecting P&L, meaning a profit and loss statement, but only found an L."
