North America E-Commerce Market Hits USD 1,435 Billion as Profit Pools Shift From Merchandise to Monetization
According to Ken Research, the North America E-Commerce Market was valued at USD 1,326 billion in 2025 and is normalizing to roughly USD 1,435 billion in 2026, expanding at a 8.20% CAGR toward USD 2,128 billion by 2031. Buyer growth is slowing in a market where 87% of the Americas population was already online in 2024, so the real contest is no longer about acquiring first-time shoppers. It is about who can monetize existing traffic through marketplace commissions, advertising, memberships and fulfillment services while absorbing rising returns and cross-border cost pressure.
Research Basis: This analysis draws on Ken Research market sizing, marketplace and retailer disclosure benchmarking, digital-buyer and payment-infrastructure review, cross-border customs and privacy-policy interpretation, and logistics-capacity evaluation.
Key Takeaways
- Market Size: The report places the market at USD 1,326 billion in 2025, with the United States contributing an estimated 93.1% of regional retail e-commerce value.
- Monetization Shift: Amazon's North America segment generated USD 29.6 billion in operating income during 2025, per the report, showing how seller services and advertising now outweigh pure merchandise margin.

Market At A Glance
North America E-Commerce Market Snapshot
- Market Size: The report estimates the market at USD 1,326 billion in 2025, rising toward USD 1,435 billion in 2026.
- Largest Application: Third-party marketplaces dominate the business-model segmentation because they aggregate seller supply, logistics services and buyer traffic.
- Fastest-Growing Area: The fulfillment-model segment is shifting fastest, led by on-demand delivery and marketplace-managed logistics.
- High-Growth Uses: Retail media, digital grocery, marketplace seller services and paid fulfillment are outpacing core merchandise sales.
- Market Implication: Buyers should evaluate platforms on monetization depth and logistics density, not transaction volume alone.
Market Size and Growth
Value growth is holding at an 8.20% forecast CAGR even as the 8.9% historical CAGR from 2020 to 2025 normalizes, per the report, because pandemic-era channel migration has already moved through the comparison base. For buyers and investors, this means the next five years reward operators that can lift order frequency and basket size rather than simply add new shoppers.
Mobile Commerce Crosses the Majority Threshold
Mobile transactions represented 68.0% of regional e-commerce value in 2025 and are projected by the report to exceed 75% of transaction value by 2031. Separately, smartphone transactions reached an estimated 71.8% share of U.S. e-commerce in 2025, reinforcing that app engagement and low-friction checkout are becoming baseline requirements rather than differentiators.
Mexico's Connectivity Runway Outpaces Mature Markets
Mexico reached 100.2 million internet users in 2024 and 31.1 million internet-connected households in 2025, per the report, giving it the strongest buyer-expansion runway in the region even as its real e-commerce value-added growth moderated from 8.5% in 2023 to 7.1% in 2024. That moderation signals household spending power, not connectivity, is now the binding constraint on Mexican growth.
Artificial Intelligence Reshapes Merchandising Economics
97% of large U.S. retailers planned to deploy AI for the 2025 holiday season, the report indicates, spanning demand forecasting, inventory allocation and personalized merchandising. Walmart research cited in the report found up to a 16% improvement in search relevance, suggesting AI's near-term payoff is concentrated in conversion efficiency rather than headline cost reduction.
Competitive Landscape
Competition concentrates around large marketplaces and omnichannel retailers, while category specialists compete on assortment and fulfillment. The report counts 8 new entrants in the past five years against a base of 3,800,000 total players, evidence that entry barriers are real but not prohibitive at the margin.
Marketplace and Omnichannel Leaders
- Companies: Amazon, Walmart, Costco Wholesale.
- Strategic Position: These operators combine scale, logistics density and advertising inventory; Amazon's 10% North America sales growth in 2025 and Walmart's advertising and membership fees generating an estimated 27% of FY2026 operating profit, per the report, show monetization now rivals merchandise margin as a profit source.
Marketplace Specialists
- Companies: eBay, The Home Depot.
- Strategic Position: eBay's USD 11.1 billion in 2025 global revenue, per the report, illustrates monetization value beyond underlying merchandise, while Home Depot's category depth protects share in project-driven, higher-consideration purchases where pure marketplace breadth matters less.
Returns and Last-Mile Economics Are Becoming the Real Margin Battle
Retailers face a persistent trade-off: 82% of consumers prioritize free returns, yet approximately 9% of returns were fraudulent in 2025, per the report, forcing investment in identity controls and item-level risk scoring. USPS shipping volume declined 4.6% year over year for the nine months ended June 2025 even as revenue rose, the report notes, signaling structural yield pressure across the delivery network.
- Free-return expectations limit retailers' ability to pass reverse-logistics costs to consumers without hurting conversion.
- Fraudulent-return rates near 9% are pushing category-specific return policies and consolidated return centers.
- Carrier yield pressure raises the value of retailers that control their own last-mile fulfillment capacity.
- For buyers and operators, returns technology and fulfillment orchestration are now procurement priorities, not back-office afterthoughts.

Cross-Border Customs and Data Rules Are Reshaping Regional Strategy
The USMCA framework protects electronic authentication and cross-border data flows for the three-country bloc, per the report, but physical goods remain exposed to tariff and customs-documentation requirements. Canada applies 10 PIPEDA principles to commercial personal-data handling, the report notes, directly shaping consent design and cross-border processing for platforms operating across all three markets.
- CBP's collection of more than USD 1 billion after 2025 de minimis reform directly raises landed costs for cross-border sellers.
- Digitally transmitted products retain USMCA Chapter 19 protection while physical goods face origin and classification exposure.
- Privacy-compliance fragmentation across the United States, Canada and Mexico raises the cost of a single regional data architecture.
- Policymakers and platform operators should treat compliance capability as a market-entry gate, not a downstream legal task.
Analyst View
By 2028, the competitive divide in this market will run between platforms that convert existing traffic into recurring, high-margin revenue and those still dependent on merchandise-margin growth alone. Winners will pair logistics density with advertising and membership monetization; operators that cannot fund fulfillment investment through non-merchandise revenue will face compressing margins as returns and carrier-yield pressure persist. Waiting past this planning window risks ceding retail-media and seller-services share to platforms already scaling those revenue lines.
Strategic Implications by Stakeholder
- For Manufacturers: Direct-to-consumer channel investment should prioritize retention economics over new-buyer acquisition spend.
- For Distributors: Fulfillment orchestration and returns technology are now differentiators, not cost centers to minimize.
- For Investors: Advertising, membership and fulfillment-fee revenue lines merit heavier underwriting weight than gross merchandise value alone.
- For Buyers: Mexico-focused infrastructure and cross-border compliance capability represent the clearest incremental growth opportunity through 2031.
Strategic Outlook
Four forces will define value creation through 2031: mobile-first checkout crossing 75% of transaction value, retail-media and membership income broadening profit pools beyond merchandise margin, Mexico's connectivity gains converting into durable buyer growth, and returns-and-compliance capability determining which operators protect margin. Buyers evaluating adjacent opportunities can compare this market against broader e-commerce industry reports and competition benchmarking studies before committing capital to a specific channel strategy.
