U.S. and global holiday ecommerce sales are projected to experience year-over-year growth in 2026, driven by emerging trends such as AI-powered referrals, the increasing adoption of flexible payment options, a surge in cross-border transactions, and dynamic shifts in Amazon’s marketplace share. This forecast, building upon a decade of trend analysis, anticipates a strong performance for online retailers during the crucial November 1 to December 31 period.
Ecommerce Poised for Significant Expansion
U.S. online holiday sales are anticipated to climb by approximately 8% during the 2026 holiday season, surpassing the growth observed in the previous year. This projection aligns with recent performance indicators, including Adobe’s report of $257.8 billion in online consumer spending with U.S. merchants during the 2025 holiday season, a 6.8% increase. Furthermore, the four-day June 2026 Prime Day event saw a 9.3% rise in ecommerce purchases from U.S. sellers, signaling continued momentum in the digital marketplace.
While the National Retail Federation (NRF) has not yet released its specific 2026 holiday ecommerce forecast, its broader expectation for full-year retail sales (encompassing both online and brick-and-mortar channels) is a 4.4% increase. This figure represents an acceleration from the average annual growth of 3.6% observed over the past decade, excluding the exceptional circumstances of the pandemic. The NRF’s optimistic outlook for overall retail health suggests a favorable environment for ecommerce, with the projected 8% growth in online holiday sales exceeding both last year’s performance and the NRF’s full-year retail prediction. This indicates a continued consumer preference for digital shopping channels, even as brick-and-mortar retail experiences a resurgence.

As consumer behavior evolves, the ability of digital platforms to cater to festive shopping needs remains a critical factor in overall retail success.
AI’s Growing Influence on Conversion Rates
A pivotal trend shaping the 2026 holiday shopping season is the increasing efficacy of generative AI tools in driving conversions. Shoppers referred from AI-powered platforms are expected to exhibit a conversion rate at least 25% higher than those originating from non-AI channels. This trend is not entirely new, as evidenced by Adobe’s findings from the previous holiday season, where AI-referred shoppers demonstrated a 31% higher conversion rate compared to other traffic 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 their non-AI counterparts, even as traffic from AI tools experienced year-over-year growth. While the current volume of AI-driven site visits represents a small fraction of the total ecommerce market, its influence is steadily expanding. As more consumers integrate tools like Gemini, ChatGPT, and similar AI assistants into their shopping journeys, the conversion rates derived from these channels are expected to normalize closer to those seen in traditional search and other established digital marketing avenues. Consequently, even as AI adoption broadens, its superior conversion performance is anticipated to be a defining characteristic of the 2026 holiday shopping season.
The implications of this trend are significant for retailers. Investing in AI-driven marketing strategies and optimizing website experiences for AI-referred traffic will become increasingly crucial for capturing a larger share of the online holiday market. The ability of AI to understand and anticipate consumer needs, offering personalized recommendations and streamlined purchasing pathways, is likely to be a key differentiator.
Buy-Now, Pay-Later Services to Surpass $22 Billion Milestone
The convenience and flexibility offered by buy-now, pay-later (BNPL) services are projected to fuel over $22 billion in U.S. online purchases between November 1 and December 31, 2026. The appeal of BNPL solutions during the Christmas season is particularly strong, as consumers seek to manage their gift-giving budgets without the immediate financial strain of a lump-sum payment or the high interest rates associated with traditional credit cards.
This sustained consumer preference for deferred payment options is expected to push 2026 holiday BNPL spending past the $22 billion mark for the first time, solidifying postponed payments as an increasingly common and integral part of the online shopping landscape. This trend reflects a broader shift in consumer financial behavior, where accessibility and budget management are prioritized.
The growing prevalence of BNPL services has also garnered attention from regulatory bodies. In recent years, there have been increasing discussions and initiatives aimed at establishing clearer guidelines and consumer protections for these rapidly expanding payment methods. While specific regulatory actions for 2026 remain fluid, the industry is adapting to a more scrutinized environment, balancing innovation with responsible lending practices. The projected surge in BNPL usage highlights its established role in facilitating consumer spending, particularly during peak retail periods.
International Ecommerce Continues Its Upward Trajectory
Cross-border purchases are set to constitute approximately 20% of worldwide Black Friday-Cyber Monday ecommerce spending in 2026, underscoring the globalization of online retail. International shopping has transitioned from a niche activity to a mainstream consumer behavior. DHL’s "2026 E-Commerce Trends Report" indicates that 70% of global online shoppers now purchase from sellers in other countries, an increase from 60% in the preceding year. Moreover, 45% of these consumers engage in cross-border purchases more than once a month.
Chinese merchants currently dominate this international sales landscape, with 59% of international shoppers purchasing from Chinese sellers, nearly double the 32% who buy from U.S. sellers. The primary driver for this cross-border preference is attributed to lower prices. Discount marketplaces based in China are widely utilized, with platforms like Temu (41% of shoppers), Shein (32%), and Alibaba or AliExpress (22%) seeing significant engagement.
These established purchasing habits are expected to persist through the holiday shopping season, projecting that international transactions will account for roughly one in every five dollars spent online globally during the crucial Black Friday-Cyber Monday period. This trend presents both opportunities and challenges for domestic retailers. It highlights the need for competitive pricing strategies and efficient international shipping solutions. Simultaneously, it underscores the growing global competition that U.S. businesses face, necessitating a strategic approach to reach international consumers or defend against foreign market entrants.
The expansion of cross-border ecommerce also brings logistical complexities, including customs duties, international shipping costs, and varying consumer protection laws. Retailers looking to capitalize on this trend must navigate these intricacies effectively to ensure a seamless customer experience.
Amazon Sellers Face Shifting Marketplace Dynamics
A notable shift is anticipated in Amazon’s marketplace dynamics for the fourth quarter of 2026, with third-party sellers projected to account for 60% or less of the company’s worldwide units sold. This represents a slight erosion of the dominant share previously held by independent sellers. Third-party sellers constituted 62% of worldwide units sold in Q4 2024 and 61% in Q4 2025. The share dipped to 60% in Q1 2026 before recovering to 61% in the second quarter.
The expectation is that Amazon’s own retail operations will gain sufficient traction during the fourth quarter to maintain third-party sellers at or below the 60% threshold of paid units sold. This trend suggests a strategic rebalancing by Amazon, potentially favoring its own branded products or increasing its direct retail offerings to meet consumer demand.
The implications of this shift are multifaceted. For third-party sellers on Amazon, it may indicate a more competitive environment within the platform, potentially impacting visibility and sales volume. Retailers might need to diversify their sales channels beyond Amazon or focus on strategies to enhance their competitive edge on the platform. For Amazon, this strategic adjustment could be aimed at optimizing profitability, gaining greater control over product offerings, or responding to evolving consumer preferences that favor direct purchases from the retail giant. This dynamic also raises questions about the long-term sustainability of the marketplace model for third-party sellers and the potential for increased competition from Amazon’s own brands.
Retrospective: Evaluating Past Predictions
Reflecting on the predictions made for the 2025 holiday shopping season provides valuable context for current forecasts. Last year’s predictions included rapid fulfillment, Canadian cross-border purchases, small business growth, AI shopping adoption, and consumer confidence.
-
Near-Instant Gratification (Insufficient Data): 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 validated due to the absence of specific fulfillment-speed data in Comscore’s annual "State of Digital Commerce Report" for 2025.
-
Canadian-American Relations (Unclear Outcome): The forecast that at least 55% of Canadian shoppers would make a holiday purchase from a U.S. ecommerce store remains unclear. While Canada and the U.S. are significant trading partners, tariff disputes have influenced consumer sentiment. Transaction data proving the precise purchase behavior of 55% of Canadians from U.S. ecommerce sellers was not readily available.
-
Small-Business Growth (Insufficient Data): The prediction of smaller U.S. online merchants experiencing approximately 10% holiday revenue growth in 2025, reaching roughly $15.5 billion, could not be substantiated with post-holiday datasets that specifically isolated this segment.
-
AI Shopping at 50% (Accurate): The prediction that at least half of North American shoppers would utilize AI for holiday shopping, and that AI product discovery would become the top ecommerce traffic source, proved accurate. Survey data from Synchrony indicated U.S. usage at 56%, while Epsilon reported 29%.
-
Consumer Confidence (Accurate): The prediction regarding strong consumer confidence was validated by Epsilon’s findings, which showed average holiday spending reaching $1,190, 52% above consumers’ preseason expectations. Adobe’s report of record U.S. online sales at $257.8 billion, a 6.8% increase, further supported this assertion.
Since 2013, the consistent analysis of ecommerce trends has aimed to provide actionable insights for businesses and consumers alike, anticipating the evolving landscape of digital commerce. The upcoming 2026 holiday season, with its confluence of technological advancements and shifting consumer behaviors, is poised to be another significant chapter in this ongoing evolution.
