U.S. and global holiday ecommerce sales are projected to experience year-over-year growth in 2026, with key drivers including the increasing influence of Artificial Intelligence in customer referrals, the widespread adoption of flexible payment options, a surge in cross-border transactions, and the dynamic market share shifts within Amazon’s vast ecommerce ecosystem. This outlook is based on a comprehensive analysis of current market trends and historical performance, signaling another strong season for online retailers.
For over a decade, tracking and forecasting ecommerce trends during the crucial holiday shopping period has become a critical exercise for businesses and consumers alike. The upcoming 2026 holiday season, spanning from November 1st through December 31st, is anticipated to continue this upward trajectory, building upon the momentum of previous years.
Ecommerce Growth Exceeds 8%
The United States online holiday sales are predicted to rise by approximately 8% compared to the same period in 2025. This projection is underpinned by recent performance indicators. Adobe’s analysis of the 2025 holiday season revealed that consumers spent $257.8 billion online with U.S. merchants, marking a 6.8% increase from the prior year. More recently, the mid-year 2026 Prime Day event demonstrated a significant 9.3% surge in ecommerce purchases from U.S. sellers during its four-day run.
While the National Retail Federation (NRF) has yet to release its specific 2026 holiday forecast, their broader outlook for full-year retail sales (encompassing both online and brick-and-mortar channels) anticipates a 4.4% increase. This figure represents an acceleration from the average annual growth of 3.6% observed over the past decade, excluding the extraordinary circumstances of the pandemic. The consistent growth in overall retail indicates a healthy consumer spending environment, which is expected to translate directly into a stronger performance for the ecommerce sector. The projected 8% growth for holiday ecommerce thus positions the online channel to outpace both last year’s holiday performance and the NRF’s full-year retail prediction, highlighting its increasing dominance in consumer spending.
AI-Driven Referrals Boost Conversion Rates
A significant development shaping the 2026 holiday shopping landscape is the enhanced performance of customers referred through generative AI tools. These AI-driven referrals are expected to convert at a rate at least 25% higher than those originating from non-AI channels during the peak shopping season. This trend is not entirely new; it has been observed in previous holiday periods. Adobe reported that during the last Christmas season, shoppers referred by AI tools exhibited a 31% higher conversion rate compared to traffic from other sources. This advantage was even more pronounced on Thanksgiving Day, reaching 54%, and on Black Friday, where AI referrals converted 38% better.
The momentum has continued into 2026. During the June Prime Day event, AI-referred shoppers converted 40% better than those from non-AI channels, despite an overall year-over-year increase in traffic from AI tools. While the current volume of AI-driven site visits remains a relatively small fraction of the total ecommerce market, its impact on conversion rates is undeniable. As more consumers integrate AI assistants like Gemini, ChatGPT, and similar platforms into their daily routines and shopping habits, the conversion rates for AI-referred traffic are expected to move closer to the benchmarks established by traditional search engines and other established online channels. This suggests that AI is not only reaching a broader consumer base but is also becoming a more effective tool for driving sales, making it a crucial element for retailers to leverage during the upcoming holiday season.
Buy Now, Pay Later Services Surpass $22 Billion
The popularity of Buy Now, Pay Later (BNPL) services is set to continue its upward trajectory, with projections indicating that these flexible payment options will finance over $22 billion in U.S. online purchases between November 1st and December 31st, 2026. The appeal of BNPL services during the Christmas season is particularly strong. Shoppers often aim to purchase gifts for loved ones without overwhelming their immediate monthly budgets or incurring high interest rates typically associated with credit cards.
This inherent consumer preference for managing gift expenses over time is expected to drive BNPL spending past the $22 billion mark for the first time during the 2026 holiday period. The increasing prevalence of postponed payment options signifies a shift in consumer financial behavior, making it a more common and accepted method of completing purchases, especially for larger ticket items or during periods of increased spending. Industry analysts anticipate that this trend will necessitate greater financial literacy among consumers and potentially lead to more robust regulatory oversight of BNPL providers.
International Ecommerce Continues Its Global Ascent
Cross-border ecommerce is poised to capture a significant share of global online spending during the Black Friday-Cyber Monday period of 2026, accounting for approximately 20% of all transactions. International shopping has evolved from a niche activity to a mainstream consumer behavior. DHL’s 2026 E-Commerce Trends Report highlighted this shift, revealing that 70% of global online shoppers now purchase from sellers in other countries, an increase from 60% in the previous year. Furthermore, 45% of these international shoppers make cross-border purchases more than once a month.
Merchants based in China currently dominate these international sales. A substantial 59% of global online shoppers report buying from Chinese sellers, nearly double the 32% who purchase from U.S. sellers. The primary driver for this cross-border preference is the availability of lower prices. Discount marketplaces originating from China, such as Temu, Shein, and Alibaba/AliExpress, are widely utilized by consumers, with 41% of shoppers reporting the use of Temu, 32% using Shein, and 22% engaging with Alibaba or AliExpress. These established buying habits are expected to persist through the holiday shopping season, solidifying the importance of cross-border ecommerce and influencing global sales patterns during the critical Black Friday-Cyber Monday window. This trend presents both opportunities and challenges for domestic retailers, requiring them to consider international logistics, currency conversion, and competitive pricing strategies.
Amazon’s Marketplace Dynamics Shift
Within the vast Amazon ecosystem, third-party sellers are projected to account for 60% or less of the platform’s worldwide units sold during the fourth quarter of 2026. Marketplace sellers have experienced a gradual, albeit slight, erosion of their share against Amazon’s own direct retail operations in recent years. In the fourth quarter of 2024, third-party sellers represented 62% of worldwide units sold, a figure that dipped to 61% in Q4 2025. This trend continued into the first quarter of 2026, where their share fell to 60%, before recovering slightly to 61% in the second quarter.
The expectation is that Amazon’s own retail business will gain sufficient momentum during the crucial fourth quarter to maintain third-party sellers at or below the 60% threshold of paid units. This subtle shift could be attributed to various factors, including Amazon’s strategic merchandising, increased investment in its own brands, or evolving commission structures. For third-party sellers, this necessitates a keen awareness of these dynamics, potentially requiring them to adapt their strategies to remain competitive on the platform, perhaps by focusing on unique product offerings, enhanced customer service, or more aggressive pricing.
A Look Back at Previous Predictions
Examining the predictions made for the 2025 holiday shopping season provides valuable context for understanding the evolving ecommerce landscape. Five key predictions were put forth: rapid fulfillment, increased Canadian cross-border purchases, small business growth, widespread AI adoption in shopping, and strong consumer confidence.
Rapid Fulfillment: The prediction that at least 35% of November and December ecommerce orders would be received or picked up within 24 hours could not be definitively verified due to the absence of a 2025 edition of Comscore’s annual State of Digital Commerce Report, which was expected to provide the necessary fulfillment-speed data.
Canadian Cross-Border Purchases: The forecast that at least 55% of Canadian shoppers would make a holiday purchase from a U.S. ecommerce store faced challenges in verification. While Canada and the U.S. remain significant trading partners, trade disputes had previously impacted Canadian sentiment towards American companies and products. Definitive transaction data to confirm the predicted penetration rate was not readily available.
Small Business Growth: The projection that smaller U.S. online merchants would experience approximately 10% holiday revenue growth in 2025, reaching roughly $15.5 billion, also proved difficult to substantiate. A post-holiday dataset specifically isolating the revenue of this segment was not found.
AI Shopping at 50%: This prediction proved to be accurate. It was anticipated that at least half of North American shoppers would utilize AI for their holiday shopping, and that AI product discovery would emerge as the leading source of ecommerce traffic. Survey data from various sources, including Synchrony (56% U.S. usage) and Epsilon (29% U.S. usage), indicated significant adoption rates, supporting the prediction of AI’s growing influence.
Consumer Confidence: This prediction was also validated. Epsilon’s findings revealed that average holiday spending reached $1,190, exceeding consumers’ preseason expectations by 52%. This robust spending was further supported by Adobe’s report of record U.S. online sales totaling $257.8 billion, a 6.8% increase.
Since 2013, a consistent pattern of growth has been observed in ecommerce, with predictions often aligning with the market’s trajectory, underscoring the enduring importance of strategic foresight in this dynamic sector. The insights gleaned from past seasons continue to inform the projections for the upcoming 2026 holiday shopping period, highlighting the interconnectedness of technological advancements, consumer behavior, and economic conditions in shaping the future of online retail.
