Uber's high-margin advertising profit is at risk if bookings move to AI agents or other surfaces within three years. Roughly 18%+ of its ~$5B FY25 net income, excluding a $5B tax benefit, is estimated to come from advertising, based on $1.75B of ad revenue at an assumed 70% operating margin and 22% tax rate. Even sticky customers will have little reason to open the app and look at ads, so it is unclear how much ad revenue Uber can keep. x.comÂ
