AI and Technology Innovation Reshaping Global E-Commerce in 2026

E-commerce has entered a phase where AI and technology innovation are less about launching another storefront and more about re-architecting the commerce stack around intelligence, automation, and trust. The shift is visible in the scale of digital selling itself. EMARKETER’s 2024 worldwide forecast projected that retail e-commerce sales would pass the $6 trillion mark in 2024 and represent 20.1% of all retail sales globally. (emarketer.com) At the same time, UN Trade and Development has highlighted that “business e-commerce” is far larger than consumer retail e-commerce: across 43 economies representing about three quarters of global GDP, UNCTAD reports business e-commerce sales grew nearly 60% from 2016 to 2022, reaching $27 trillion.

Those numbers sit alongside an uncomfortable reality: measurement is lagging the market. UNCTAD explicitly frames the lack of official statistics as a “significant gap,” complicating policy design and international comparability at a moment when business models, ordering channels, and intermediaries are mutating quickly. (unctad.org) That statistical lag is no longer an academic issue. It is becoming a commercial issue, because “what counts as e-commerce” is increasingly contested when transactions begin in AI assistants, flow through digital intermediaries, and complete via new forms of delegated authorization. The OECD’s 2025 revision of its e-commerce definition reflects this reality by adding guidance on digital intermediaries, subscriptions, and AI-assisted transactions, explicitly aiming to keep measurement statistically relevant as ordering channels evolve. (oecd.org)

Against this backdrop, innovation in e-commerce is concentrating in three high-impact arenas.

First is the discovery layer, where generative AI is altering how consumers form intent, compare options, and navigate to merchants. Second is the operating layer, where robotics and machine intelligence are changing the economics of fulfillment, forecasting, and service at scale. Third is the trust layer, where payments security, data governance, and regulation are expanding the perimeter of what “good commerce” means in practice.

AI and Technology Innovation in E-Commerce at Scale and in Transition

E-commerce has grown quickly, but growth is uneven and no longer guaranteed. EMARKETER notes that e-commerce growth worldwide is expected to decelerate in 2025, which it attributes largely to economic weakness in China alongside trade-war-related stresses in major North American markets. (emarketer.com) Yet EMARKETER also projects that e-commerce will still represent 20.5% of total global retail sales in 2025, up from 19.9% in 2024. (emarketer.com) The implication is not a reversal of digitization, but a maturing market where technology-driven differentiation increasingly determines who captures value within a slower-growing pie.

This is the environment in which AI and adjacent technologies are being pulled from experimentation into the core of commerce. McKinsey’s August 2024 analysis of generative AI in retail frames the magnitude in economic terms, estimating gen AI could unlock $240 billion to $390 billion in value for retailers, equivalent to an industry-wide margin increase of 1.2 to 1.9 percentage points. (mckinsey.com) Even allowing for uncertainty in any macro estimate, the framing itself is telling: leading research now treats AI not as incremental software, but as a potential margin structure event.

From Search Box to Conversation

The most visible change in e-commerce is not in warehouses or payments rails. It is in the interface customers use to shop.

Generative AI is moving commerce from “query and click” to “ask and decide,” with the first-order effect being a change in how information is assembled for buyers. Amazon’s rollout of Rufus is emblematic. Amazon describes Rufus as a generative AI shopping assistant that can answer questions in the Amazon app and draw on Amazon’s catalog “with information from across the web,” allowing customers to type or speak queries and ask follow-ups in a chat-style flow. (aboutamazon.com) In parallel, Google has been rebuilding shopping surfaces around AI. In October 2024, Google described a “transformed Google Shopping” rebuilt with AI, including AI-generated briefs that summarize “top things to consider,” dynamic filters, and integration of virtual try-on supported by generative AI and AR tools. (blog.google)

These product moves are occurring at the same time that AI-assisted discovery is measurably sending traffic into retail sites. Adobe Analytics reported that, during the 2025 holiday season, “generative AI tools drove a 693.4% increase in traffic to retail sites,” based on Adobe’s measurement of U.S. e-commerce across over 1 trillion visits to retail sites. (news.adobe.com) Adobe has also published behavioral comparisons for visitors arriving via generative AI assistants, reporting that those shoppers were 33% less likely to “leave immediately,” spent 45% more time on-site, and viewed 13% more pages per visit. (business.adobe.com)

Consumer-facing data points support the same direction of travel: shoppers are incorporating AI into their journeys, even if behavior is uneven across demographics and categories. Deloitte’s 2025 Holiday Retail Survey reports that 33% of respondents planned to use generative AI in their shopping journey, with common uses including deal-finding and summarizing reviews. (deloitte.com) Separately, Deloitte’s 2025 Connected Consumer study, based on a survey of about 3,500 U.S. consumers, reports that 53% were either experimenting with generative AI or using it regularly, up from 38% in 2024. (deloitte.com) And BCG’s January 2026 research reports that shopping-related GenAI use grew 35% from February 2025 to November 2025. (bcg.com)

The strategic significance is not only that more people are “using AI.” It is that commerce journeys are being reassembled into a new mediation layer where:

  • Information is summarized, not merely ranked.
  • Comparison can happen before a shopper reaches a merchant’s site.
  • Recommendations can be framed as “best options for me” rather than “best results for my keywords.”

The New Economics of Product Discovery

If AI assistants increasingly organize discovery, the economics of traffic acquisition and brand visibility begin to shift in ways that are still unfolding. Traditional e-commerce has relied on a relatively stable bargain: search engines send merchants traffic; merchants bid for visibility; platforms monetize attention; attribution is built around clicks.

Two developments are pressuring that bargain.

First, AI-generated summaries change where attention concentrates. Google’s own product communication around AI Overviews emphasizes that the experience includes links and that Google expects to continue “sending valuable traffic” to websites, with ads appearing in dedicated slots. (blog.google) At the same time, Google labels some AI-generated briefs as “experimental,” explicitly acknowledging the possibility of errors. (blog.google) That combination—greater synthesis paired with acknowledged imperfection—creates a new trade-off for merchants: the discovery layer can compress friction and accelerate decision-making, but it can also compress nuance, reduce differentiation, and introduce new failure modes where misinformation is scaled.

Second, attribution becomes harder when a journey starts in an AI assistant and ends elsewhere. The growth in AI-referred traffic documented by Adobe makes this less hypothetical; it is already altering the mix of referral sources. (news.adobe.com) As AI-mediated discovery expands, the “unit economics” of marketing—what a visit costs, how it converts, how it is tracked—becomes more dependent on how AI platforms expose links, data, and measurement.

One emerging response is for commerce platforms to integrate AI deeper into the merchant operating environment in ways that also position them for a more agent-mediated web.

Catalogs Become Living Data Systems

E-commerce has long treated product catalogs as structured data. The newest wave treats the catalog as a living system that can be interpreted, expanded, translated, and re-packaged into multiple buying contexts—human and machine.

Shopify’s evolution is illustrative because it sits at the intersection of merchant enablement and platform infrastructure. Shopify positions “Shopify Magic” and “Sidekick” as AI for commerce, describing Sidekick as an AI assistant that connects merchants’ data points to “deliver insights” and create content while also helping execute tasks. (shopify.com) In May 2025, Reuters reported Shopify launched an “AI Store Builder” that generates store layouts, images, and text from descriptive keywords, aiming to reduce the effort required to design an online store. (reuters.com)

These developments point to a deeper structural change: as generative systems are applied to catalog enrichment and storefront creation, the bottleneck shifts from “designing a site” to governing the underlying product truth.

In practice, that truth spans multiple dimensions:

  • Accuracy and consistency of product attributes across channels
  • Rights and provenance of images and text used in listings
  • Localization quality for global selling
  • Safety and compliance constraints for regulated categories
  • Resilience against “AI drift” where content changes faster than the underlying product reality

The tension is that generative systems can accelerate production of content, but they can also accelerate propagation of errors. The risk is not only hallucinated text; it is operational confusion—returns, complaints, regulatory exposure—caused by subtle inaccuracies scaled across thousands of SKUs.

Personalization at Industrial Scale and Under Constraint

E-commerce personalization has existed for decades, but two forces are changing its nature.

The first is capability. Generative AI enables not just “which product to show” but “which narrative to present,” potentially generating different creative variations for different contexts, languages, and customer segments. Deloitte’s 2025 survey-focused work on generative AI in retail and consumer products describes the use of gen AI in functions such as marketing, customer service, and e-commerce, while emphasizing that many organizations are early in adoption and that governance is becoming a differentiator for trust and long-term value. (deloitte.com)

The second force is constraint. Personalization is not a purely technical problem; it is now embedded in privacy expectations and regulatory frameworks.

Deloitte’s 2025 Connected Consumer study reports that concerns about data privacy and security have risen, with the share of respondents worried about privacy and security increasing from 60% to 70% in one year, alongside broader concerns about pace of innovation and safeguards. (deloitte.com) This matters for e-commerce because the marginal gains of personalization often depend on data access, but consumer tolerance for opaque data practices is moving in the opposite direction.

The result is a more complex personalization landscape where value creation sits at the intersection of:

  • First-party data strategies and consent
  • Model governance and explainability norms
  • Brand risk tolerance around automated targeting and messaging
  • Regulatory limits that vary by region and product category

Automation Moves Deeper into Fulfillment

For many executives, AI in e-commerce still evokes chatbots and recommendations. Yet the largest structural effects may come from the operating layer—how inventory moves, how warehouses run, and how delivery promises are kept profitably.

Amazon’s disclosure about its robotics and AI milestones is one of the clearest windows into this layer at industrial scale. In June 2025, Amazon stated it had deployed its one millionth robot and introduced a generative AI foundation model called DeepFleet designed to coordinate robot movement and improve the travel efficiency of its robot fleet by 10%. (aboutamazon.com) Amazon also described its robotics footprint as spanning more than 300 facilities worldwide. (aboutamazon.com)

A few implications follow from this kind of automation, without requiring heroic assumptions about every retailer becoming Amazon.

  • Scale advantages can compound. When optimization models improve efficiency across a global network, gains are not linear; they propagate through labor, throughput, and delivery speed.
  • Service promises become algorithmic products. The ability to offer fast delivery at acceptable cost increasingly depends on forecasting and orchestration, not only on carrier rates.
  • Operational transparency becomes more important. As systems make more decisions automatically, debugging customer outcomes (late shipments, split deliveries, substitutions) becomes a governance problem as much as a logistics problem.

UNCTAD’s Digital Economy Report 2024 situates this in a broader context: the digital economy’s growth carries environmental and infrastructure implications, including rapidly expanding device ecosystems and compute demands. UNCTAD notes annual smartphone shipments have more than doubled since 2010 to 1.2 billion in 2023 and projects IoT devices will surge to 39 billion by 2029, emphasizing the environmental footprint of digital growth. (unctad.org) While those figures are not e-commerce-specific, they underscore the infrastructure reality behind “always-on” commerce, real-time logistics visibility, and the compute-intensive AI systems now being embedded across retail operations.

Immersive Commerce and the High-Consideration Problem

Not every commerce category benefits equally from conversational discovery. The most sensitive categories for digital conversion tend to be those where “fit” matters—apparel, cosmetics, home furnishings, and other products where returns can be costly and customer satisfaction is linked to expectations management.

Here, AR and computer vision are being integrated into mainstream commerce surfaces rather than treated as novelty add-ons. Google’s 2024 update describes its shopping experience incorporating virtual try-on, powered by generative AI and AR shopping tools, alongside AI-generated research briefs and personalized shopping feeds. (blog.google)

The more consequential point is not that virtual try-on exists. It is that immersive interfaces are being fused with the discovery layer: the same AI system that helps define what a shopper wants can also offer a simulation of what it might look like, reducing the cognitive distance between browsing and buying. This integration is part of a broader pattern where multimodal inputs—text, images, and eventually video—become native to the shopping journey rather than exceptions.

Trust, Security, and the Expanding Compliance Surface

As AI increases automation in shopping and operations, it also expands the attack surface and the compliance perimeter.

Payments are an anchor point because they combine sensitive data, complex third-party dependencies, and tight regulatory expectations. One concrete example is the ongoing transition to PCI DSS v4.x. The PCI Security Standards Council has stated that PCI DSS v4.0.1 does not change the March 31, 2025 effective date for new requirements, and that PCI DSS v4.0 was retired on December 31, 2024, leaving v4.0.1 as the active version. (blog.pcisecuritystandards.org) Even for executives not immersed in security standards, the message is clear: the payments security baseline is tightening, and e-commerce cannot treat compliance as a static annual exercise.

Meanwhile, consumer trust dynamics are changing in parallel with AI adoption. Deloitte’s Connected Consumer findings include that one-third of surveyed users encountered incorrect or misleading information when using gen AI, and 24% reported data privacy issues—signals that the “trust problem” is not theoretical. (deloitte.com) In commerce settings, the cost of these failures can be immediate: incorrect product claims, misleading policies, fabricated reviews, or data leakage from poorly governed integrations.

Regulation Meets the Commerce Stack

In many markets, AI governance is moving from voluntary principles to enforceable obligations. The European Union’s AI Act provides the most structured example because it defines categories, governance mechanisms, and an application timeline.

According to the European Commission’s AI Act policy page, the AI Act entered into force on August 1, 2024 and will be fully applicable on August 2, 2026, with key earlier milestones including application of prohibited AI practices and AI literacy obligations from February 2, 2025 and obligations for general-purpose AI models from August 2, 2025. (digital-strategy.ec.europa.eu) For e-commerce, this matters less as an abstract “AI regulation story” and more as an operational reality: systems that influence consumer decisions, perform biometric categorization, automate customer service, or govern credit-like decisions can move into more scrutinized territory depending on deployment context.

Importantly, regulation also interacts with the cross-border nature of e-commerce. A merchant selling internationally can find itself operating under overlapping requirements: privacy frameworks, consumer protection regimes, product safety laws, and now AI-specific obligations. The compliance surface expands further when third-party AI tools are embedded into workflows, because accountability is increasingly shared across a chain of providers.

B2B Commerce and the Quiet Reinvention of Procurement

While consumer e-commerce captures headlines, the larger value pool in commerce is business e-commerce—orders, replenishment, industrial procurement, and platform-mediated trade among firms. UNCTAD’s $27 trillion estimate for business e-commerce sales underscores this scale. (unctad.org)

AI’s role in B2B commerce is structurally similar to B2C—discovery, personalization, automation—but the constraints differ. B2B transactions tend to involve negotiated pricing, complex catalogs, compliance documentation, and multi-stakeholder approvals. In that environment, the value of better search, better product information, and faster quoting can be amplified because the transaction size is larger and the friction cost is higher.

The OECD’s updated e-commerce definition explicitly includes guidance on digital intermediaries and AI-assisted transactions. (oecd.org) That inclusion reflects how B2B commerce increasingly blends “ordering” with platform services—catalog management, identity and access management, invoicing, and embedded finance—where the distinction between “a website sale” and “a mediated transaction” becomes less clear.

Toward Agentic Commerce

The most debated frontier is agentic commerce—AI agents acting on a user’s behalf to search, compare, and transact. Unlike earlier conversational systems that primarily answered questions, agentic systems are positioned to take actions.

McKinsey’s October 2025 report defines agentic commerce as shopping powered by AI agents acting on our behalf via multistep chains of actions, and it frames potential magnitude: by 2030, McKinsey estimates the U.S. B2C retail market alone could see up to $1 trillion in orchestrated revenue from agentic commerce, with global projections reaching $3 trillion to $5 trillion. (mckinsey.com) This is a projection, not an outcome; its value lies in signaling what sophisticated market observers believe is plausible if adoption and infrastructure mature.

Observed behavior suggests the preconditions are forming. Adobe’s data shows AI-driven traffic is already arriving at retail sites at sharply higher rates than the prior year and behaving differently once it arrives. (news.adobe.com) BCG reports that shopping-related GenAI use increased materially during 2025. (bcg.com) Deloitte reports a significant minority of consumers planned to use gen AI during a major retail moment, the holiday season. (deloitte.com)

Agentic commerce also clarifies why identity, authorization, and trust are becoming central to e-commerce innovation. If an agent can execute transactions, the core question becomes “who is acting, on whose authority, under what constraints, and with what recourse when things go wrong.” McKinsey’s report explicitly frames trust and risk as central challenges as agents gain autonomy across systems. (mckinsey.com)

What Changes When AI Becomes the Interface

E-commerce is evolving from a channel into an adaptive system. The strategic unit is shifting from the “storefront” to the “decision flow”—how intent is formed, how options are compared, how fulfillment promises are made, and how trust is maintained across increasingly automated interactions.

The near-term reality is heterogeneous. Some segments are using AI primarily for productivity and content acceleration. Others are reworking logistics and operations at scale. And the most advanced are positioning for a world in which AI agents become a meaningful source of demand.

What is consistent across these trajectories is the logic of the new commerce stack:

  • Discovery is moving toward AI-mediated conversation and synthesis. (aboutamazon.com)
  • Operations are becoming more algorithmic as automation expands into warehouses and networks. (aboutamazon.com)
  • Governance is becoming a competitive constraint, not a back-office function, as regulation and consumer expectations tighten around privacy, accuracy, and security. (digital-strategy.ec.europa.eu)

In 2026, that combination is redefining what “innovation” means in e-commerce. It is less about adding features and more about redesigning the market’s interfaces—between buyers and sellers, between merchants and platforms, and between automation and accountability.
