uberxUber is beating Lyft in the U.S. — at least in terms of revenue numbers.

A new study from FutureAdvisor that analyzed 3.8 million credit and debit card transactions found that Uber reeled in 12 times the amount of revenue than Lyft from June 2013 to May 2014. Uber provided seven times more rides while charging 1.6 times as much, on average, for ride fees.

The study also noted that while both Uber and Lyft enjoyed a 25 percent growth rate in the U.S. month over month in June 2013, the companies saw just a 10 percent growth rate in June of this year.

One more tidbit from the study: Of the 3.8 million cards, 96,000 had used either Uber or Lyft.

While growth may be slowing down in the U.S., Uber — which is operating in 44 countries — is attracting more and more customers elsewhere. Uber CEO Travis Kalanick spoke this week at TechCrunch Disrupt and touted his company’s growth in Europe and Beijing. Lyft, meanwhile, has yet to launch outside of the U.S.

The two companies have been engaging in a price war for more than a year now and Uber recently had to handle a media storm over the company’s tactics against Lyft.

Update: 3:40 p.m.:

Lyft is denying the study’s validity. Here’s a statement from the company:

This study does not track the extent of our actual growth which as an example, this past May was 40% MOM not the reported 10%. Since May, we have doubled the number of cities we are in including New York City, Miami and Austin.
