The global ecommerce landscape is poised for continued expansion during the 2026 holiday season, with robust year-over-year growth anticipated in both U.S. and international markets. This anticipated surge is projected to be significantly shaped by emerging trends, including the increasing influence of artificial intelligence in consumer referrals, the widespread adoption of flexible payment options, a rise in cross-border transactions, and the dynamic shifts occurring within Amazon’s marketplace share. These factors are expected to collectively drive a more sophisticated and expansive online shopping experience for consumers worldwide.
For over a decade, I have been closely observing and forecasting ecommerce trends and sales figures for the crucial holiday shopping period. The following five predictions represent a comprehensive outlook for the 2026 holiday season, built upon current market data, emerging consumer behaviors, and technological advancements.
Ecommerce Poised for 8% Growth in the U.S.
U.S. online holiday sales, encompassing the period from November 1st through December 31st, are projected to experience an approximate 8% increase compared to the same timeframe in the preceding year. This forecast builds upon recent performance indicators that signal a healthy and expanding digital retail sector.
Adobe’s comprehensive analysis of the 2025 holiday season revealed that U.S. consumers collectively spent $257.8 billion online with domestic merchants, marking a 6.8% uplift from the previous year. Further underscoring this upward trajectory, recent data from the four-day June 2026 Prime Day event indicated a significant 9.3% increase in ecommerce purchases from U.S. sellers. This mid-year surge serves as a strong predictor for sustained consumer engagement and spending in the latter half of the year.
While the National Retail Federation (NRF) has not yet released its official 2026 holiday forecast, their broader outlook for full-year retail sales—encompassing both online and brick-and-mortar channels—projects a 4.4% increase. This figure represents a notable acceleration from the average annual growth of 3.6% observed over the past decade, excluding the extraordinary circumstances of the pandemic. The NRF’s projection of overall retail growth inherently suggests a positive environment for ecommerce, which typically mirrors and often outpaces broader retail trends.
My 8% forecast for holiday ecommerce growth specifically positions the sector to outperform both last year’s digital sales performance and the NRF’s more general full-year retail prediction. This optimistic outlook is grounded in the persistent consumer shift towards online shopping, further amplified by the increasing convenience and personalized experiences offered through digital platforms.
The Christmas season remains a pivotal period for online merchants, driving substantial revenue and shaping annual sales figures.
AI-Driven Referrals Achieve Superior Conversion Rates
A key driver of enhanced conversion rates during the 2026 peak shopping season is expected to come from shoppers referred via generative AI tools. These AI-referred shoppers are predicted to convert at a rate at least 25% higher than those arriving from non-AI driven channels.
This trend is not entirely novel; preliminary data from the previous Christmas season already highlighted the efficacy of AI in driving conversions. Adobe reported that shoppers originating from AI referrals converted 31% better than those from other sources. During peak shopping days, this advantage was even more pronounced: on Thanksgiving Day, the conversion rate uplift reached 54%, and on Black Friday, AI referrals converted 38% better.
The momentum has carried into 2026. During the June Prime Day event, AI-referred shoppers demonstrated a 40% higher conversion rate compared to non-AI channels, even as traffic originating from AI tools saw year-over-year growth. This sustained performance indicates that AI is increasingly influencing purchase decisions and guiding consumers more effectively towards conversion.
It is important to acknowledge that the overall volume of AI-driven site visits, while growing, still represents a relatively small fraction of the total ecommerce market. However, as more consumers integrate tools like Gemini, ChatGPT, and similar generative AI platforms into their research and shopping processes, the conversion rates achieved through these channels are expected to normalize towards the benchmarks set by traditional search engines and other established online traffic sources. Therefore, even as AI adoption broadens its reach to a wider consumer base this holiday season, its superior conversion performance is likely to persist, solidifying its role as a powerful driver of sales.
Buy Now, Pay Later Services to Exceed $22 Billion
The adoption and utilization of Buy Now, Pay Later (BNPL) services are projected to finance over $22 billion in U.S. online purchases between November 1st and December 31st, 2026. This marks a significant milestone, indicating the increasing reliance of consumers on flexible payment solutions, particularly during periods of heightened spending.
The appeal of installment-based payment plans during the Christmas season is multifaceted. Consumers often face the dual pressures of gift-giving generosity and the desire to manage their personal finances without incurring substantial debt or high interest rates typically associated with credit cards. BNPL services directly address these concerns by allowing shoppers to spread the cost of their purchases over manageable installments, effectively smoothing out budget impacts.
This inherent appeal is expected to propel U.S. BNPL spending during the 2026 holiday period beyond the $22 billion threshold for the first time. This trend signals a broader normalization of postponed payment options, moving them from a niche offering to an increasingly common and accepted method of purchasing goods and services online. The growing integration of BNPL at checkout across a wide range of retailers further supports this trend, making it a convenient and accessible option for a vast number of consumers.
International Ecommerce Continues Its Ascent
Cross-border purchases are anticipated to constitute approximately 20% of all global Black Friday and Cyber Monday ecommerce spending in 2026. This indicates a robust and expanding trend of consumers engaging with international retailers to source products, driven by a variety of factors including price, product availability, and unique offerings.
International shopping has transitioned from an occasional activity to a commonplace practice for a significant portion of the global online population. DHL’s comprehensive 2026 E-Commerce Trends Report highlighted that a substantial 70% of global online shoppers now regularly purchase from sellers in other countries, a notable increase from 60% a year prior. Furthermore, 45% of these international shoppers engage in cross-border purchases more than once a month, underscoring the frequency and integration of this behavior into their regular shopping habits.
Chinese merchants currently dominate the cross-border ecommerce market, with an impressive 59% of international shoppers purchasing from sellers based in China. This figure nearly doubles the 32% who buy from U.S. sellers. The primary driver for this preference is consistently cited as lower prices. The widespread availability and popularity of Chinese discount marketplaces further fuel this trend. Reports indicate that 41% of shoppers utilize Temu, 32% shop on Shein, and 22% engage with platforms like Alibaba or AliExpress.
These established buying habits are expected to persist and influence holiday shopping patterns, thereby driving international purchases to represent roughly one in every five dollars spent online worldwide during the critical Black Friday-Cyber Monday sales period. This trend presents both opportunities and challenges for domestic retailers, necessitating strategies to compete with international pricing and product offerings, or conversely, to leverage global marketplaces to expand their own reach.
Amazon Sellers See Market Share Stabilize
Third-party sellers on Amazon are projected to account for 60% or less of the platform’s total worldwide units sold during the fourth quarter of 2026. This forecast indicates a stabilization, and potentially a slight decline, in the market share held by third-party sellers relative to Amazon’s own retail operations.
In recent quarters, marketplace sellers have experienced a marginal loss of ground to Amazon’s direct retail business. Third-party sellers constituted 62% of worldwide units sold in the fourth quarter of 2024, a figure that dipped to 61% in Q4 2025. This downward 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 segment will gain sufficient traction during the crucial fourth quarter holiday shopping period to maintain third-party sellers at or below 60% of the total paid units sold. This dynamic reflects Amazon’s strategic decisions to potentially prioritize its first-party sales or to adjust its marketplace fee structure and seller policies in ways that subtly shift the balance. For third-party sellers, this trend may necessitate greater differentiation in product offerings, enhanced marketing strategies, and a focus on building direct customer relationships to mitigate the impact of increased competition from the platform itself.
A Look Back at 2025 Predictions
My five predictions for the 2025 holiday shopping season included the rise of rapid fulfillment, increased Canadian cross-border purchases, growth among small businesses, AI integration in shopping, and the influence of consumer confidence. Evaluating these forecasts reveals a mixed but largely accurate picture of the evolving ecommerce landscape.
Rapid Fulfillment: Insufficient Data. I had predicted that shoppers would receive or pick up at least 35% of their November and December ecommerce orders within 24 hours. Unfortunately, definitive proof for this prediction remains elusive due to a lack of granular data. Comscore’s annual State of Digital Commerce Report, which was expected to provide such fulfillment-speed metrics, was not published in its 2025 edition, leaving this specific forecast unverified.
Canadian-American Relations: Unclear Impact. My prediction was that at least 55% of Canadian shoppers would make a holiday purchase from a U.S. ecommerce store. While Canada and the U.S. remain significant trading partners, geopolitical and economic factors, including tariff disputes, have influenced consumer sentiment towards American companies and products. However, without specific transaction data that isolates this particular consumer behavior, it is difficult to definitively confirm whether the 55% threshold was met.
Small Business Growth: Data Scarcity. I had forecasted that smaller U.S. online merchants would experience approximately 10% holiday revenue growth in 2025, reaching roughly $15.5 billion. Similar to the rapid fulfillment prediction, a lack of post-holiday datasets specifically isolating the performance of this segment of online retailers prevented a conclusive assessment of this forecast.
AI Shopping at 50%: Accurate. The prediction that at least half of North American shoppers would utilize AI for their holiday shopping, and that AI-driven product discovery would emerge as the leading source of ecommerce traffic, proved to be largely correct. Survey data from various firms, including Synchrony and Epsilon, indicated significant adoption rates, with Synchrony reporting U.S. usage at 56% and Epsilon at 29%. While adoption rates varied, the overall trend clearly pointed to AI’s growing prominence in the shopping journey.
Consumer Confidence: Verified. Epsilon’s findings supported the consumer confidence prediction, reporting that average holiday spending reached $1,190 per consumer, a remarkable 52% above their preseason expectations. This sentiment was further validated by Adobe’s report of record U.S. online sales, totaling $257.8 billion and representing a 6.8% increase. These figures underscore a strong consumer willingness to spend during the 2025 holiday season.
Looking ahead, the convergence of advanced AI capabilities, evolving payment infrastructures, and a globalized digital marketplace suggests that the 2026 holiday ecommerce season will be characterized by both familiar growth patterns and transformative new influences. Retailers and consumers alike will need to adapt to these dynamic shifts to navigate the increasingly complex and exciting world of online commerce.
