As Uber explained in its 2022 financial releases:
Expanded Journey Ads, our Mobility in-app ad format, now available in eight markets. Active advertising merchants during the quarter exceeded 315K. Our revenue run-rate from Advertising exceeded $500 million.
Over the years, if Uber can consolidate its advertising business, this might result in an essential improvement in profits for the company, which is still recording broad losses as of 2022.
