Despite multiple pivots and significant investments, Amazon continues to struggle in a sector that represents one of the largest consumer spending categories. "Amazon dominates ecommerce with nearly 40% market share, but grocery remains the category it just can't crack," said our analyst Suzy Davidkhanian on a recent episode of “Behind the Numbers.”

Pinterest is piloting a new shoppable recipe format with Walmart’s help. Select recipes now feature a “Shop Ingredients” button that lets users add ingredients directly to their Walmart carts. The pilot fits squarely with Pinterest’s broader goal to make every pin on its platform shoppable, a strategy designed to fully monetize its influence over product discovery and shopping trends. It also fits with Walmart's aim to establish a presence on as many shopping channels as possible, be it social commerce or ChatGPT.

Amazon, Target, and Walmart are stepping up their holiday fulfillment efforts to reassure late shoppers that gifts will arrive before Christmas. Amazon is adding clear “Arrives before Christmas” messaging and enabling delivery or pickup on many items through Christmas Eve, while Target is extending store hours and leaning on rapid curbside, in-store pickup, and same-day delivery. Walmart is expected to match or exceed last year’s Christmas Eve express cutoffs. These moves highlight how crucial last-minute reliability has become, as faster delivery speeds increasingly shape where shoppers spend and give retailers with strong fulfillment networks a powerful competitive edge.

Amazon is testing ultra-fast delivery for fresh groceries and other household essentials in some areas of Seattle and Philadelphia. The service, called Amazon Now, allows shoppers in eligible neighborhoods to receive thousands of items in 30 minutes or less. While Amazon continues to invest in its brick-and-mortar grocery business, enhancing its ecommerce initiatives appears to be taking precedence. Speeding up delivery could help Amazon extend its foothold in grocery while keeping shoppers wedded to its platform, but our forecast expects its share of digital grocery sales to dip as Walmart, pure-play grocers, and intermediary delivery platforms grow their piece of the pie.

Walmart finalized its Vizio acquisition one year ago, a move that clearly telegraphed its advertising ambitions and positioned it to be a dominant retail media player. Vizio considerably strengthens Walmart’s pitch to advertisers by giving it more opportunities to get in front of engaged audiences and providing more data for better targeting and measurement. Walmart’s newfound CTV capabilities also help establish the retailer as a full-funnel ad solution, increasing its appeal to both endemic and nonendemic brands.

Mobile will account for nearly half of US online sales in 2026 and become the dominant channel in 2027. To make the most of this shift, retailers and brands should enhance integration of their shopping apps and loyalty programs.

Brands and retailers are struggling to keep up with changes to the shopper experience as consumers adopt genAI-powered “click-less journeys.”

As AI increasingly powers everything from holiday ads to product recommendations, retailers face a critical balancing act between efficiency and authenticity. "The question isn't if retailers will use AI, it's how they'll keep using it and maintain the human touch along the way," said host Suzy Davidkhanian on a recent episode of “Behind the Numbers.”

Q3 was another strong quarter for Walmart and Amazon, and another weak one for Target. Shoppers are showing a clear preference for the convenience, product selection, and overall value that Amazon and Walmart offer, while being less impressed by Target’s assortment and shopping experience. Economic uncertainty is heightening the gap, as more shoppers turn to Amazon and Walmart for necessities like groceries while pulling back on the discretionary spending that fuels Target. Walmart's and Amazon's ability to combine low prices with an extensive product selection and fast and convenient delivery will serve them well this holiday season, while Target has the harder task of convincing price-conscious shoppers to spend on nonessential items.

Walmart and Target closed their recent earnings calls on sharply different footings, but with a surprisingly shared vision for the immediate future.

Walmart, TJX, and other US retailers are deploying body cameras to combat shoplifting, harassment, and violence against staff. While the full scope of retail theft is debatable, every stolen item chips away at revenues. With tariffs and rising costs squeezing margins, retailers are testing every lever to protect the bottom line. Body cams may help—but only if they reduce loss without eroding customer trust. Retailers should exercise care in walking a fine line between safety and scrutiny.

Walmart raised its full-year outlook again as its strong value proposition and fast-growing ad business drive broader consumer spending. It now expects net sales growth of between 4.8% and 5.1% this year, and EPS between $2.58 and $2.63. Q3 comps rose 4.5% YoY, with higher traffic and ticket size, and gains were strongest among higher-income shoppers. US ecommerce sales jumped 28%, supported by faster delivery, rising Walmart+ signups, and 33% growth in US ad sales (excluding Vizio). Walmart is also expanding to emerging channels, including ChatGPT. Its focus on value, convenience, and tech has strengthened its position, helping it compete with Amazon and capture more holiday and online spending.

Future-proofing against—and capitalizing on—advances in consumer-facing AI will be the overarching theme for retailers in 2026.

Global ad spending has steadied after a turbulent year, setting the stage for modest acceleration in 2026. Digital is still the main engine, but traditional media’s rebound will add lift as markets stabilize.

Amazon announced a breadth of AI-powered ad options on Day 1 of its annual Unboxed event designed to simplify campaign creation and deployment. Amazon’s new resources give advertisers a uniquely full-funnel solution that’s difficult to find in the crowded digital marketing world.

OpenAI’s push into commerce took a major step forward with the launch of in-app shopping on ChatGPT, though it will take time to gain traction as a meaningful retail sales channel.
