Uber Delivery has transformed from money-losing to profitable, driven by advertising revenue and operating leverage. The DoorDash competition and grocery unit economics are the key risks.
Advertising is the margin unlock for Uber's delivery business. Merchants pay for promoted placement, and Uber's cross-platform data provides unique targeting capability.
Grocery delivery doubles the TAM but with worse unit economics. The play is advertising revenue from CPG brands offsetting the delivery margin pressure.
