From Ulta Beauty’s new marketplace to Gap’s creator platform, here’s what the eight most interesting retailers from October have been up to, as ranked on our “Behind the Numbers” podcast.

Kroger and Uber are joining forces to expand their audiences and attract more incremental spending. Kroger customers will be able to order restaurant delivery—fulfilled by Uber—from the grocer’s website and app. Starting next year, Uber Eats users will be able to order groceries from Kroger’s 2,600-plus stores. Partnering with third-party delivery platforms offers pure-play grocers such as Kroger an opportunity to level the playing field with mass competitors like Walmart and Amazon. Deals like the one between Kroger and Uber will likely become more common as retailers look to reach high-intent shoppers and delivery platforms race to keep their competitors at bay.

NBCUniversal’s Peacock reduced losses to $217 million in Q3 compared with $436 million in 2024, but struggled to boost revenues and attract new subscribers—raising questions about the platform’s advertising value. Peacock shows potential for the future as it works to build its portfolio and partnerships beyond live sports—but stagnant subscriber growth for two quarters means brands should remain cautious.

Walmart unveiled a series of AI-powered tools for its app to help customers with their holiday shopping. The new features, which include an in-store savings function and AI-generated audio summaries, are meant to make Walmart’s app more useful for in-store shoppers and to simplify discovery and purchasing for customers who prefer to transact online. Retailers should follow Walmart’s lead and use AI to make it easier for customers to surface deals and quickly find what they’re looking for, whether in-store or online.

We expect US holiday sales to rise 3.6% in the final two months of the year, a slowdown from last year’s 4.4% gain, but much stronger than our May outlook, when we anticipated just 1.2% growth. The shift stems from consumers’ surprising resilience despite tariffs, inflation, and a softening labor market. Major retailers like Walmart and Amazon have reported steady demand, with tariffs adding only modest price pressures. However, spending remains uneven across income groups as higher earners benefit from wage and wealth gains. Retailers will need to emphasize affordability and value to attract cautious middle- and lower-income shoppers this season.

Eli Lilly is offering cash-pay pricing for its weight loss drug Zepbound at Walmart. This is the first time Lilly has offered a retail pharmacy pick-up option to customers who order Zepbound through LillyDirect. Walmart will soon be the only retail pharmacy where customers paying cash for Novo’s and Lilly’s GLP-1 weight loss drugs can pick up their prescriptions. This will help the company benefit from increased foot traffic as more of Lilly’s customers enter its stores.

Amazon is cutting 14,000 roles from its corporate workforce as it reshapes its organization to prepare for an agentic AI future. The layoffs are unusual for a company still posting strong growth, but Amazon framed them as part of a broader move to gain efficiencies from genAI. While most retailers have thus far refrained from citing AI as a reason for mass layoffs, that could change as tariff pressures and other headwinds force companies to cut costs—and headcount—where possible.

The US government shutdown has entered its fourth week, becoming the second-longest in modern history and increasingly straining the economy. The travel industry alone has lost nearly $3 billion, while companies like Unilever are delaying major moves due to halted SEC operations. Grocers fear SNAP benefit disruptions that could hit Walmart and Kroger hardest. Oxford Economics estimates GDP growth could fall by up to 2.4 percentage points if the shutdown persists through Q4. With holiday sales already under pressure from weak confidence and high rates, the timing couldn’t be worse for retailers or consumers.

Walmart is now the first retailer to sell Abbott’s over-the-counter blood sugar monitor in stores. Its rollout of Abbott’s Lingo CGM brings real-time health tracking to mainstream retail, helping to make advanced health tech part of everyday life. For marketers, the rollout highlights a growing opportunity to reach proactive health seekers who want personalized insights about nutrition, exercise, and stress.

Now that consumers can make direct purchases within ChatGPT, marketers and retailers must reimagine the customer journey once again.

Walmart Inc. announced a partnership with OpenAI to enable Walmart and Sam’s Club customers to make purchases within ChatGPT using the latter’s Instant Commerce feature. Even if agentic commerce’s adoption is gradual, early movers like Walmart will have the outsize advantage. Being discoverable in channels where users conduct product and pricing research could help retailers reinforce their value proposition and stay top-of-mind with prospective customers as this commerce scales up.

“Gaming is one of the most engaging channels, and what makes it particularly interesting is its ability to convert taps into transactions,” said Maya Kosovalic, vice president of marketing at L’Oréal-owned NYX Professional Makeup during Advertising Week New York.

The Bank of North Dakota and Fiserv launch the “Roughrider Coin,” the first stablecoin from the state of North Dakota. While its individual use case may be limited, it opens the door for a stablecoin issued by Fiserv on behalf of a major retailer with significant use case for processing sales. A retailer like Starbucks would be a prime candidate—it’s already ingrained the habit of loading a wallet that can only be used at Starbucks in its most loyal customers. In that case, a limited network isn’t nearly as much of a liability—it’s the whole point.

This year’s Amazon Big Deal Days sale is shaping up to be another success, according to multiple forecasts. Bain and Adobe both forecast healthy growth, while we expect Amazon's ecommerce sales to rise 8.8% YoY to $8.84 billion. A strong consumer appetite for October sales could bode well for the holiday season, although we—and most other forecasters—expect growth to slow as uncertainty weighs on spending.

Walmart’s OnePay will reportedly offer crypto trading and custody through its banking app, per CNBC. Major retailers like Walmart and Amazon can save substantial margin on each transaction if they can get consumers to use their own crypto instead of traditional payment rails. While the ramp up to stablecoin issuance would take time, more operationally ready ventures like crypto-powered remittances stand as easier plays to execute.

Walmart will remove artificial dyes and 30 other food additives from its private-label products by the beginning of 2027. Its changes follow similar pledges by other manufacturers including Kraft and General Mills. Walmart shoppers prioritize price above all’ top priority is price, but that doesn’t mean they’re not concerned about health and wellness—they just may not be able to afford premium-priced health foods.. Walmart’s decision to remove certain food additives from its private-label changes is an opportunity to bridge that gap and deliver healthier food at budget-friendly prices.

AI shopping assistants are boosting discovery and personalization, but trust issues and fulfillment challenges could limit their impact on channel migration.

Digital markets are being reshaped by genAI search and shifting platform and monetization dynamics. These 10 charts reveal the forces that will define 2025 and beyond.

OpenAI is preparing to turn ChatGPT into an advertising platform, posting a new role for an engineer to build systems for ad integration, campaign management, and attribution. The move could position ChatGPT as a new challenger to Google, Meta, and Amazon’s ad businesses. Already a major driver of referral traffic to retailers like Walmart, Etsy, and Target, ChatGPT has clear potential to evolve into a commerce and ad engine. But execution will be critical: Poorly integrated ads risk undermining user trust, even as AI-driven ad formats are projected to grow at triple-digit annual rates in the coming years.
