The American grocery aisle is no longer confined to physical space. Online grocery sales surged to $12.5 billion in September 2025, the highest monthly total on record. That surge reflects more than demand—it reflects changing expectations.
Consumers now expect grocery shopping to work around their lives instead of interrupting them. That shift in expectations is driving redesigns in everything from store layouts to delivery logistics and digital platforms.
Ordering groceries online is no longer a fringe behavior. More than 60% of U.S. households now place digital grocery orders, meaning most Americans are filling carts with taps and swipes rather than aisle walks.
Online channels now account for nearly 19% of all grocery spending. Physical stores remain essential, but the momentum is clearly digital. With year-over-year growth up 31%, grocery shopping via apps and screens has shifted from convenience to necessity.
The biggest driver is the rise of repeat buyers. These super users place four or more orders every three months and spend about 50% more per order than first-time shoppers. They mix delivery, pickup, and ship-to-home in the same month. They’re flexible, loyal, and valuable.
Older shoppers are fueling much of this growth. Consumers over 60 years old drove nearly half of the recent yearly gains. Convenience matters at every age, and once people experience friction-free shopping, they don’t go back.
The Battle for the Future of Grocery Shopping

Instacart is steadily embedding itself in physical grocery stores. Smart carts, digital shelf labels, and deli kiosks are no longer optional extras—they’re part of the pitch. The company’s aim is to run the infrastructure of the store, not simply fulfill delivery orders. That tightens its hold on retailers, but it also creates friction. In many cases, collaborators and competitors are now operating side by side at checkout.
Walmart is focused on reducing time at every step. Stores are being reworked for automation, with digital price tags that change instantly and new fulfillment hubs that accelerate order flow. Its AI assistant, Sparky, is designed to eliminate indecision by helping shoppers plan meals and assemble carts almost immediately.
Amazon’s focus remains speed above all else. Same-day grocery delivery continues to expand, with 30-minute delivery tests underway in certain markets. The aim is to close the gap between intent and arrival. Prime membership reinforces that urgency, keeping customers locked into the system.
Regional grocers are under mounting strain. They’re squeezed by big-box pricing and burdened by the cost of new technology. Data suggests many shoppers browse locally but ultimately place digital orders through Walmart or Amazon. That split behavior erodes the margins and long-term relevance of smaller chains.
What Is Really Driving This Growth

Private-label products are outperforming expectations. Once associated with compromise, they’re now trusted for consistency and price. Walmart’s Bettergoods brand generated close to $500 million in revenue in 2024. That scale places it firmly among the company’s serious growth engines.
Convenience is the second force. Speed matters more than ever. About 68% of shoppers say shorter delivery windows push them to place an order. Waiting days now feel outdated.
Convenience also means less thinking. AI tools now reduce planning time. Albertsons rolled out an AI shopping assistant to shrink a 46-minute planning session down to four minutes. Fewer decisions lead to faster checkouts and bigger carts.
Personalization ties it all together. Shoppers want value, but they also want food that fits their lives. Demand is increasing for fresh produce, high-protein foods, and products with transparent ingredient lists. Free-from claims keep growing.
Retailers are using data to recommend smarter choices. That turns shopping into a guided experience. When done right, it builds trust and keeps customers coming back.
