The Race for Faster Delivery: How Amazon and Walmart Are Redefining Shopper Expectations

A New Phase of Retail Competition: Speed to Doorstep

The rivalry between Amazon and Walmart has entered an unprecedented stage — one where delivery speed, not just selection or price, is emerging as a dominant driver of customer loyalty.

In recent updates to investors and shareholders, both companies revealed bold expansions of their logistics strategies to deliver faster — not just in urban hubs, but deep into America’s rural and suburban heartlands.

Doug McMillon, Walmart’s CEO, emphasized during an April 9, 2025, investment meeting that whether deliveries come from a store, club, fulfillment center, or even a drone, the company is aggressively focused on “getting things to people faster.” Amazon CEO Andy Jassy echoed the sentiment in his April 10 shareholder letter, noting that “when we promise faster delivery times, customers complete purchases at a meaningfully higher rate and shop with us more frequently.”

Walmart’s Ultra-Fast Push: From Same-Day to 30-Minute Deliveries

Today, Walmart reaches 93% of U.S. households with same-day delivery — a figure it plans to grow to 95% by year-end. Notably, Walmart is leveraging new geospatial technology that divides service areas into hexagonal grids, allowing it to dynamically adjust delivery zones based on real-time data about store capacity, driving times, and local demand.

One-third of Walmart’s store-fulfilled orders now involve customers opting to pay a premium for delivery within three hours. Building on that momentum, Walmart will soon pilot an “ultra-fast delivery” service, aiming for 30-minute fulfillment times — an ambition informed by its international operations, where 45-minute grocery deliveries are already standard in cities like Shanghai and Mexico City.

Drone delivery also remains a critical piece of Walmart’s fast-delivery ecosystem. The company has completed over 120,000 drone deliveries and continues to expand its drone network, especially around the Dallas-Fort Worth area.

Amazon’s Speed Records and Rural Expansion

Amazon, meanwhile, boasts staggering numbers: 9 billion items delivered same-day or next-day in 2024 alone. Central to its success is the shift to a regionalized fulfillment network and the launch of small-footprint same-day delivery centers, which now serve over 140 metro areas and are growing by 60% year-over-year.

Prime Air, Amazon’s drone initiative, has begun delivering in Arizona and Texas. Though regulatory hurdles remain, drones are particularly useful for delivering essential items like prescriptions and pet food rapidly to customers.

Amazon’s rural investment is equally notable. It’s now delivering to over 13,000 ZIP codes, covering 1.2 million square miles of the U.S., and plans to deliver over a billion packages annually to less densely populated areas — a clear signal that the battle for fast delivery is no longer just an urban story.

The Broader Implications for Retailers and Brands

For suppliers, brands, and other retailers, this arms race signals a pivotal shift. The expectation is no longer just “fast shipping” — it’s “instant fulfillment.” Retailers that lack the infrastructure or partnerships to meet these new benchmarks risk not only disappointing customers but losing them altogether.

According to McKinsey & Company, nearly 50% of U.S. consumers now consider same-day delivery a deciding factor when choosing where to shop online. As Amazon and Walmart make same-day the norm, not the exception, other retailers will face growing pressure to match or differentiate.

Moreover, the investment in delivery infrastructure — from AI-driven route optimization to drone delivery and hyperlocal micro-fulfillment centers — suggests that innovation in last-mile logistics will continue to be one of the most competitive, and most capital-intensive, arenas in retail for years to come.

Final Thoughts

Amazon and Walmart’s latest moves aren’t just about speed for speed’s sake — they represent a fundamental redefinition of what modern shoppers expect. Delivery in hours, or even minutes, is quickly becoming table stakes. For brands, suppliers, and retailers hoping to stay competitive, understanding and adapting to this new reality will be critical for long-term relevance and growth.
