The food delivery industry in the United States has undergone a seismic transformation over the past decade. What was once a niche convenience has become a mainstream consumer behavior — and a fiercely competitive battleground for restaurants, ghost kitchens, quick-service restaurant (QSR) chains, and third-party delivery platforms alike. In 2025, online food delivery revenue in the US exceeded $380 billion, with platforms like DoorDash, Uber Eats, Grubhub, and Instacart collectively processing tens of millions of orders every day across thousands of cities and zip codes.
