The company said it lost $10 billion since 2016, underscoring the extremely precarious nature of Uber’s business design. The filing revealed Uber had 91 million users on its platforms in the end of 2018.

The company, which got its start as an app-based luxury car service in San Francisco at 2009, is presently one of the most dominant transportation services from the world, controlling over 60% of the US market and logging countless rides all over the world.
