Amazon's explosive same-day delivery growth is forcing CPG brands to rethink their fulfillment strategies. As consumers' demand for speed continues to rise, so do the high last-mile costs. Let's break down Amazon's infrastructure and explore how CPG brands succeed in an increasingly speed-driven market where same-day delivery is becoming the new baseline expectation.
12 Minute Read
Amazon delivered an unprecedented 9 billion items globally via same-day and next-day delivery in 2024, fundamentally reshaping consumer expectations and forcing the entire ecommerce industry to adapt. For CPG companies competing in the rapidly evolving 2025 landscape, understanding Amazon's infrastructure and the broader competitive landscape has become critical for strategic planning.
Amazon currently operates 58 same-day hubs across the United States, with CEO Andy Jassy confirming plans to double this network to over 100 facilities. These urban fulfillment centers, typically around 100,000 square feet, stock approximately 100,000 SKUs each—a figure verified through multiple investor communications. The company's same-day delivery sales surged 65% year-over-year in Q4 2023, demonstrating explosive consumer demand for ultra-fast fulfillment.
These fulfillment gains aren’t luck—they’re the result of deliberate infrastructure investments that have reshaped the entire ecommerce landscape. To see where CPG brands need to adapt, we first have to examine the systems powering Amazon’s speed advantage.
Inside the Machine: How Amazon Built Its Speed Advantage
Amazon's same-day delivery network now covers 60% of U.S. population across more than 140 metro areas, following a 60% expansion in delivery sites during 2023. This dramatic growth stems from the company's regionalization strategy, completed in 2024, which transformed their single national network into eight interconnected regional systems. The result? 76% of orders now fulfill within the customer's region, reducing transportation distances by 10% and enabling faster, more cost-effective delivery.
The technological backbone of this operation is staggering. Amazon has deployed 750,000+ robots across its global network, with the company reaching its millionth robot milestone in July 2025. These systems have delivered remarkable efficiency gains: the Sequoia system processes inventory 75% faster while reducing order processing time by 25%. At Amazon's newest Shreveport facility, robotics integration has boosted productivity by 25% through eight coordinated robotic systems working in harmony.
While specific geographic distribution data remains proprietary, Amazon's expansion follows population density patterns, with significant presence in California, the Northeast corridor, Texas, Florida, and major Midwest markets. The company maintains multiple daily dispatch waves to maximize delivery windows, though exact timing varies by location. Their ultra-efficient operations target 2-3 hour fulfillment windows, with the GlobeSt article referencing 11-minute assembly and shipping times—though this appears to represent total fulfillment speed rather than just packing.
Keeping Up with Amazon’s Delivery Speed
The same-day market has exploded to $9.90 billion globally in 2024, projected to reach $36.2 billion by 2030 at a 20.6% CAGR. This growth has triggered an arms race among major retailers, each leveraging unique strengths to compete with Amazon's dominance.
Walmart has emerged as Amazon's most formidable competitor, extending same-day delivery to 12 million households in 2024 using advanced hexagonal grid mapping technology. Their approach allows multiple stores to fulfill single orders, maximizing inventory availability. With 4,600 store locations providing local inventory proximity, Walmart+ members ($98/year) receive free same-day delivery on orders over $35, covering 86% of U.S. households.
Target takes a premium approach through its Circle 360 membership ($99/year), leveraging its Shipt subsidiary to offer same-day delivery from 100+ retailers without price markups. The company nearly doubled next-day packages delivered in 2024 while reducing average delivery time by 11%. Target's "stores as hubs" strategy has proven highly effective, with same-day services now representing over 10% of total sales.
Specialized retailers have found success through strategic partnerships.
Home Depot invested $1.2 billion in Flatbed Distribution Centers targeting 90% coverage for same/next-day delivery, while partnering with Instacart for items up to 60 pounds.
Best Buy offers same-day delivery in 40+ metros through GEODIS, focusing on electronics with real-time tracking for large items. Meanwhile, third-party platforms like DoorDash have expanded beyond food to serve 115,000+ non-restaurant retailers, creating a flexible ecosystem for smaller merchants.
The technology revolution enabling ultra-fast fulfillment
Speed isn’t just about trucks—it’s powered by robotics, AI, and automation working in sync. Amazon now runs over 750,000 robots across its network, including AutoStore units, Sparrow arms, and Proteus—the first autonomous mobile robot gliding among workers.
These AI-driven systems have boosted throughput by up to 25% while cutting processing times by 75%. High-speed conveyors and ergonomic stations keep products flowing, reducing miles walked per shift and shaving lead times. Together, these upgrades helped Amazon absorb peak demand during Prime Day 2024 without major slowdowns.
Beyond the warehouse, Amazon’s AI now forecasts demand for 400M+ products daily, while its Project P.I. model spots defects 3× more effectively than humans. Machine learning also reroutes 390,000 drivers in real time, adjusting for traffic and weather.
The next leap is autonomous delivery.
Amazon’s MK30 drone delivers 5-pound packages in under 60 minutes, with a goal of 500M deliveries annually by decade’s end. Meanwhile, micro-fulfillment centers are projected to scale to 7,300 by 2030, up from just 86 in 2021, enabling thousands of daily orders while bringing inventory closer to dense urban markets.
The Economics of Same-Day Delivery
Despite its growth, same-day delivery remains economically challenging. Last-mile costs range from $7-$13.50 per package, representing over 50% of total shipping costs. McKinsey research indicates same-day delivery costs are typically 3x higher than next-day delivery initially, with nearly half reporting six-figure startup costs (median $400,000).
Labor represents up to 95% of costs in manual operations, with 30% of shippers experiencing driver shortages and high turnover rates. Geographic limitations further complicate economics—same-day delivery proves viable primarily in urban areas with 50,000+ inhabitants, requiring minimum density of 200 packages per delivery day for profitability.
Technology offers potential solutions. AI-powered optimization can reduce forecast errors by 30-40% while processing 30,000 calculations per minute. Warehouse robotics show 18-36 month payback periods while reducing labor costs by 20-30%. Most dramatically, drone delivery costs could drop from current $13.50 to just $1.50-$2.00 per delivery with scaled operations.
Amazon's European expansion reveals global ambitions
Amazon's international growth demonstrates the scalability of its model. The company now offers same-day delivery in 135+ European locations across seven countries, with 20 new cities launching in 2025. German operations alone delivered 590 million items same/next-day in 2024, a 15% year-over-year increase.
European expansion faces unique challenges including varied regulations across 27 EU member states, urban density restrictions, and aggressive sustainability requirements. Amazon has invested €700+ million in European robotics and AI while deploying 300+ Rivian electric vans and establishing micromobility hubs in 20 cities. All delivery packaging is now 100% recyclable, addressing stringent EU environmental regulations.
How Ecommerce Brands Can Surf Amazon’s Same-Day Wave
For CPG companies, Amazon's infrastructure investments and the competitive responses create both opportunities and challenges. The proliferation of same-day delivery options means consumers increasingly expect rapid fulfillment for everyday essentials—a category where CPG brands excel in the rapidly growing ecommerce landscape. However, this also intensifies pressure on inventory management, requiring strategic positioning of products across multiple fulfillment networks.
How CPG Brands Can Ride the Wave:
Channel strategy optimization- With 53% of retailers offering same-day delivery and 65% planning implementation, CPG brands must carefully evaluate channel partnerships. Amazon's dominance doesn't preclude opportunities with Walmart, Target, and specialized retailers who may offer better terms or category focus.
Inventory positioning- The shift to regional networks requires sophisticated demand forecasting and strategic inventory placement. CPG brands should leverage retailer data to position fast-moving SKUs in same-day fulfillment centers while maintaining cost discipline on slower-moving items.
Packaging innovation- With last-mile costs consuming over 50% of shipping expenses, lightweight, efficient packaging becomes crucial. The 43% reduction in packaging weight achieved by leading companies demonstrates significant opportunity for cost reduction and sustainability gains.
Technology integration- Real-time visibility across channels is no longer optional. CPG brands need robust systems integrating with retailer APIs to manage complex fulfillment networks while maintaining service levels.
Consumer segmentation- Understanding the 61% willing to pay for speed versus the 90% prioritizing free shipping enables targeted strategies. Premium products might leverage same-day delivery for differentiation, while everyday essentials focus on reliable, free delivery options.
