Consumer demand for same-day and next-hour delivery has grown faster than carrier infrastructure can support. New research reveals the gap, who bears the cost, and which networks are closest to closing it.
Key Takeaways
Amazon set a standard in 2019 that no honest logistics professional expected the rest of the industry to match within five years. It has been matched in expectation if not yet in execution. According to the 2026 Delivery Experience Report produced by Narvar and Ipsos across a panel of 8,400 U.S. consumers, 34% of respondents now describe same-day delivery as a standard expectation rather than a premium service, up from 14% in 2021. The supply side of that equation tells a different story: the same survey found that only 19% of carriers outside the top five national networks report the node density and operational infrastructure needed to fulfill same-day orders profitably at current market-clearing price points. That 15-percentage-point gap between what consumers expect and what carriers can deliver without losing money is the central challenge defining last-mile strategy in 2026.
"We have customers telling us that same-day is table stakes. That is not a conversation about what they want. That is a conversation about what they will accept from a competitor if we cannot provide it," said one chief commercial officer at a regional carrier operating across the U.S. Southeast, speaking on background.
The same-day expectation is not uniformly distributed across the consumer landscape, and understanding its geography is critical to building a rational response. Urban markets with high Amazon Prime penetration, particularly New York, Los Angeles, Chicago, and Seattle, have the highest consumer expectations and, in many cases, the carrier infrastructure to partially satisfy them. The tension is sharpest in suburban and exurban ZIP codes, where consumers have been conditioned by two-hour grocery delivery and Amazon same-day windows, but where the fulfillment node density required to execute those promises profitably simply does not exist outside the largest national players. McKinsey's 2025 Future of Delivery report found that same-day fulfillment costs in low-density suburban markets run 2.7 times higher per parcel than in high-density urban zones, a gap that closes only when either order volumes justify local dark store investment or micro-fulfillment is subsidized by the retailer.
Retail segment matters as much as geography. Grocery and pharmacy, where same-day delivery has been normalized by Instacart, Gopuff, and the major chains' own apps, show the highest consumer expectation rates: 61% of grocery shoppers surveyed in the Narvar report expect same-day availability as a baseline. Consumer electronics and beauty follow, with 48% and 42% respectively. Apparel, despite being a high-return category with complex fulfillment, shows same-day expectations of only 29%, suggesting that speed pressure in fashion logistics still lags behind the food and personal care categories.
The operational infrastructure closest to making same-day delivery consistently profitable is built around two capabilities working together: forward-positioned inventory through dark stores or micro-fulfillment centers, and AI-driven dispatch that collapses the window between order placement and driver assignment. Dark stores, retail-format locations repurposed exclusively for order picking rather than customer-facing shopping, have expanded rapidly in North America since 2023. The Food Industry Association's 2025 Fulfillment Benchmark Study counted 1,840 active dark store locations in the continental U.S., a 67% increase from 2023, with grocery, pharmacy, and beauty categories accounting for 74% of the total.
When a dark store is positioned within 4 miles of a target delivery address, average same-day fulfillment times drop to between 38 and 52 minutes from order placement, according to operational data published by Fabric Logistics in its 2025 Micro-Fulfillment Impact Report. At that proximity, the unit economics of same-day delivery approach parity with standard two-day delivery in dense markets, because the shorter drive time reduces driver-hours per parcel and enables higher stop density on return routes.
"The retailers who figured out same-day economics earliest did not just build dark stores. They built them in exactly the right places, based on actual order data. The ones that are still struggling planted inventory based on real estate availability rather than demand maps."

The gig economy plays an enabling role in bridging gap between dark store coverage and full same-day capacity. Carriers and retailers that have built dispatch integrations with platforms including DoorDash Drive, Roadie, and Shipt report using gig drivers for between 18% and 34% of same-day volume, with the share spiking above 50% during peak promotional periods. The variable cost structure of gig dispatch allows operators to scale delivery capacity rapidly without the fixed cost of maintaining a staffed fleet large enough to handle peak demand. The trade-off is consistency: gig driver acceptance rates, arrival times, and handling quality vary more than those of dedicated employed drivers, a distinction that matters acutely for high-value or fragile product categories.
The economics of same-day delivery create a persistent question about cost allocation. The Narvar consumer data is unambiguous about what shoppers prefer: 71% of respondents said they would choose a retailer offering free same-day delivery over one charging a fee, all other variables held equal. What that preference does not account for is the cost reality on the operational side. Delivering a parcel same-day in a non-dense market typically costs between $12 and $22 more than standard two-day delivery, a gap that vanishes in dense urban zones with mature micro-fulfillment infrastructure but remains significant in most of the country.
Retailers are handling this gap in three ways, as identified in Deloitte's 2026 Retail Fulfillment Cost Survey of 340 North American retailers. The first is full absorption, in which same-day delivery is offered as a free service and the cost is embedded in margin. Fewer than 30% of surveyed retailers use this approach across all categories. The second is threshold-based absorption, in which same-day delivery is free above a minimum order value, typically between $35 and $75. The third is explicit fee capture, passing a transparent same-day surcharge of between $4.99 and $9.99 to the consumer at checkout.
The carriers best positioned to benefit from the next 18 months of same-day investment are those that can offer retail partners a credible cost-per-delivery guarantee in dense markets while presenting a clear node expansion roadmap for the suburban markets that remain financially out of reach today. Retailers are increasingly willing to co-invest in fulfillment infrastructure, in the form of dark store lease guarantees or minimum volume commitments, with carriers that can demonstrate the analytical rigor to place inventory in the right locations and the operational discipline to hit delivery windows consistently. Speed alone is no longer a sufficient value proposition. Speed at a defensible unit economics level is the only offer that closes a commercial deal.
Fuel surcharges, wage inflation, and failed deliveries are compressing last-mile margins. The carriers pushing back are doing it with route density and smarter hybrid models.
42 cities have introduced low-emission freight restrictions in 18 months. Carriers that build compliant fleets and perimeter hubs now will hold a lasting structural advantage.
Early adopters of AI route optimization are reporting real cost savings, but implementation pitfalls have caught several large carriers off guard. Here is what the data shows.
