Lyft's driver-generated revenue went up 25 percent to hit $1 billion in the second quarter of 2017, up from $800 million in Q1. In aggregate, the company has a ways to go before it rivals Uber's $8.25 billion gross bookings it earned in the same period -- but that figure only improved 10 percent quarter-on-quarter. Ergo, Lyft is growing faster.

Lyft has been trying to win the PR war too, like when it donated $1 million to the ACLU in the immediate wake of Trump's first travel ban (Uber set up a $3 million legal defense fund for affected drivers). Whether that's enough to seize market share while Uber struggles is another question. But sources told Bloomberg that Lyft registered almost as many rides in the first half of 2017 as in all of last year, so it's clearly expanding services alongside increasing its gross revenue.
