May 2026 · E-commerce Notes

May did not introduce a completely new e-commerce story. It showed that AI commerce is moving from experimentation into the systems that shape visibility, conversion, and checkout.

AI shopping is no longer only about helping shoppers find products. In May, the stronger signal was infrastructure: product feeds, structured data, marketplace content, availability, ads, carts, and fulfillment all becoming part of AI-led commerce.

At the same time, delivery speed is being pushed further, tariffs and supply chain disruptions are affecting sellers, and regional e-commerce growth continues to move at different speeds.

Below is a curated selection of May updates observed over the course of the month.

Technology & AI in Commerce

May’s AI updates were less about isolated shopping assistants and more about infrastructure. Platforms are starting to connect AI more directly to search, advertising, product information, carts, checkout, and product pages.

The common thread is clear: AI commerce is becoming more dependent on structured product data, marketplace content, availability, pricing, and review signals. These are no longer only product page inputs. They are becoming part of how AI-led journeys surface, compare, and support purchase decisions.

AI shopping becomes more embedded inside Amazon’s ecosystem

Amazon launched Alexa for Shopping, combining Rufus and Alexa+ into a more unified AI shopping experience. The assistant can help shoppers compare products, create shopping guides, track prices, reorder essentials, and buy items when they reach a target price.

Amazon also introduced a feature that lets shoppers ask questions while listening to AI-generated product summaries, with responses based on product information, reviews, and other product page data.

Together, these updates show how AI is moving closer to Amazon’s core shopping journey, influencing comparison, evaluation, product questions, and purchase timing inside the same ecosystem.

AI commerce moves closer to ads, carts, and checkout

Google unveiled Universal Cart, a new agentic commerce tool expected to work across Google Search, Gemini, YouTube, and Gmail. The tool is designed to let shoppers add products from multiple merchants into a single cart experience.

OpenAI is also making it easier for e-commerce companies to run shopping ads in ChatGPT, with advertisers able to generate ads from product catalogs using product names, images, and attributes.

These updates point to a wider platform shift. AI commerce is becoming connected to advertising, product feeds, and checkout infrastructure, not only recommendation quality.

The supply side of AI commerce is moving faster than shopper behavior

Retailers and brands are moving quickly to launch shopping apps inside AI platforms such as ChatGPT and Claude. Early reporting suggests shopper adoption and conversion are still uncertain.

This is a useful counterpoint to the broader AI commerce momentum. Platforms are building the infrastructure, but shopper behavior has not fully caught up yet.

Platforms & Fulfillment

While AI shaped the front end of commerce in May, fulfillment remained one of the clearest areas of platform competition. Delivery speed continues to move from differentiator to expectation.

Faster delivery is not only a customer promise. It is an inventory, availability, and last-mile execution test. As delivery promises become faster, the cost of weak availability or poor fulfillment visibility becomes harder to absorb.

Amazon pushes faster delivery into urgent-use categories

Amazon launched Amazon Now in the U.S., offering delivery in 30 minutes or less in several cities, with plans for wider expansion. The service focuses on urgently needed products, including groceries and everyday essentials, and relies on micro-fulfillment centers to support faster delivery.

The update reinforces how speed is becoming part of the everyday shopping promise, especially in categories where timing and availability directly affect purchase decisions.

Consumer Behavior & Market Pressures

May’s consumer and market updates showed that online demand remains strong, but growth is not removing pressure. Cost control, supply chain resilience, and operational visibility continue to matter.

Growth is still there, but it is coming with more friction. Cost, sourcing, shipping, inventory, and channel performance are becoming harder to separate.

Online retail growth remains strong

U.S. e-commerce sales in April 2026 grew by more than 10% year over year, outpacing total retail sales growth for the month. Online retail also grew at more than twice the rate of total retail sales in both March and April.

The data points to continued strength in digital demand, even as broader retail conditions continue to shift.

Tariffs and supply chain disruption pressure sellers

Tariffs, rising logistics costs, and supply chain disruptions continued to affect small and mid-sized businesses in the U.S. In a May survey, 96% of SMBs said tariffs had directly affected their shipping, sourcing, or supply chains over the past year.

The impact is not limited to cost. Many businesses reported revenue loss, inventory shortages, missed sales, and customer dissatisfaction linked to supply chain disruption.

Consumer brand manufacturers continue growing online

Consumer brand manufacturers had one of the strongest growth profiles among online retailer types in the first half of the 2020s. Their five-year CAGR reached 9.3% by the end of 2025, slightly ahead of web-only retailers.

This points to the continued strength of brand-owned digital channels, while marketplace performance remains critical across third-party retail environments.

Social Commerce & Regional Market Highlights

Regional updates in May showed that e-commerce growth remains active but uneven. Social commerce is gaining stronger seller participation, while several markets continue expanding at different speeds.

The larger takeaway is that market maturity is becoming more varied. Some markets are still expanding quickly in transaction volume, while others are focused more on optimization, technology adoption, and customer experience.

TikTok Shop becomes part of Spain’s seller infrastructure

In Spain, 21,000 local sellers were active on TikTok Shop, and 18.7% of Spanish e-commerce businesses were using the platform.

The update shows how quickly social commerce can become part of the selling infrastructure in a market. TikTok Shop is shaping discovery, seller participation, fulfillment capabilities, and category-level relevance.

Italy’s e-commerce market continues steady growth

Italy’s e-commerce market reached an estimated 90.6 billion euros in 2025, up 6.1% from the previous year. Travel and tourism remained the largest online sector, followed by marketplaces and leisure.

Compared with faster-growing markets, Italy shows a steadier growth profile, with online businesses focusing on website optimization, technology, customer experience, AI adoption, and marketing.

Closing Observation

May’s updates point to an e-commerce environment where the path to purchase is becoming more connected, but also more demanding.

AI is moving into search, ads, carts, product pages, and shopping assistants. Delivery expectations are accelerating. Social commerce is gaining local traction. At the same time, tariffs, fulfillment costs, and supply chain disruptions continue to pressure sellers.

The common thread is execution.Being present across channels is no longer enough. Products need to be visible, trusted, accurately represented, competitively positioned, and available when shoppers are ready to buy.

The advantage will sit with teams that can keep those basics accurate while the buying journey becomes less predictable.

We will continue tracking these shifts month by month.
