Welp, here it is folks.
I am surprised to see how much Lyft's market share has increased in the past couple of years, too:
The company, which got its start as a college carpooling service called Zimride in 2007, says it has achieved 39 percent market share in the US as of December 2018, up from 22 percent in December 2016. This new growth comes from new riders and drivers, as well as more frequent rides from existing users. For the quarter ended December 31, 2018, Lyft says it had 18.6 million “Active Riders” and over 1.1 million drivers.
