Uber Commands the National Ride-Sharing Market. But Lyft Rules Portland.

The smaller ride-sharing company dominates in Portland.

You don't "Uber over" to a friend's house in Portland. You get a Lyft.

Portland is the rare U.S. city where Lyft dominates its much larger competitor, Uber, in the ride-hailing business.

That's according to recent data from Second Measure, a company that analyzes credit-card transaction data. It looked at receipts billed to each ride-hailing company.

It's not exactly clear why Lyft is winning the Portland market. But Lyft's ride-sharing business in the U.S. has grown faster that Uber's in recent years. And Portland is a left-leaning activist town: As Uber went through successive scandals including the #deleteUber campaign, the company drew repeated bad press for its practices here.

(The New York Times revealed in 2017 that Uber had used a software tool called Greyball to evade Portland regulators as it began operating here in defiance of city officials in 2014.)

Uber and Lyft did not dispute the data.

Lyft has invested heavily in Portland, but attributes its success here to other reasons than capitalizing on anti-Uber sentiment.

"Portlanders choose Lyft because of our commitment to efficient and reliable service," says Lyft spokeswoman Lauren Alexander, "and our dedication to effecting positive change in our cities,"

Now it's Lyft's turn to be in conflict with city regulators. As the company moves to pass laws at the state level that could blot out Portland's existing regulations, City Hall has cried foul.

"Similar statewide legislation has been introduced in years past and, as this year, supported by both Lyft and Uber," says Alexander.

Uber, for a change, is keeping a lower profile, saying it is looking for "consensus" on the bill.
