Letting an artificial intelligence assistant buy a product is a bigger decision than asking it to recommend one. Walmart’s proposed buying controls deserve attention because they show how a retailer can keep authorization and returns in its hands. We also examine ChatGPT’s advertising expansion and Meta’s rising ad prices: more access and platform revenue do not establish better merchant returns. The insights also show why attention, usage and purchases need different measures.

1️⃣ Walmart proposes separate permissions for assistants that buy for customers.

2️⃣ ChatGPT advertising expands, while typical merchant returns remain unproven.

3️⃣ Meta’s ad prices rise, but platform growth cannot establish advertiser profit.

Insights

4️⃣ Amazon’s US fresh-food buyers return more often; the gap is not causal proof.

5️⃣ Brands put social shopping ahead of AI assistants in their channel priorities.

6️⃣ A survey in France, Germany and the UK separates AI comparison from autonomous buying.

LET’S ENTER THE MAZE!

1️⃣ News

Walmart plans controls for AI shopping assistants

The Maze: Walmart plans separate permissions for AI assistants buying for Walmart and Sam’s Club customers. Its announcement concerns account-based shopping, without establishing worldwide availability.

Source: Walmart. Walmart’s announced interface separates agent orders and shows purchase-approval settings; this is a product illustration, not a live account test.

The Details:

  • Separate the assistant’s purchases. Agent Profiles, due next month, would distinguish software-made orders. Shoppers would connect each assistant through Walmart and choose purchase approvals or spending limits.

  • Connect directly to the retailer. Walmart’s Agent Gateway would let approved assistants shop without clicking through human-facing webpages. It begins with a beta for companies and developers.

  • Keep a hand on checkout. Walmart can demand confirmation even below a spending limit. Agents cannot receive card details or change payment methods. The usual returns process would cover agent mistakes.

MarketMaze Take: Welcoming an outside shopping assistant need not mean surrendering customer control. Walmart is proposing permission to buy, with conditions attached.

  • The merchant still sets the rules. Retailers elsewhere can study the same split: an assistant handles the conversation while the store keeps account authorization and returns. That is an operating lesson, not an overseas rollout.

  • Access needs an outcome. Walmart has disclosed no agent order or error baseline here. More completed purchases with fewer mistakes would establish value; allowing bots inside alone does not.

2️⃣ News

ChatGPT ads expand to 26 more countries

The Maze: OpenAI is expanding ChatGPT ads to 26 more countries, including 14 in Latin America. Its stated coverage reaches 89 countries, widening access for local businesses and international brands.

Source: OpenAI. OpenAI’s illustrative interface shows a labeled ad below a separate ChatGPT answer; it does not verify delivery in any new market.

The Details:

  • Businesses can buy directly. Advertisers can use technology partners or Ads Manager, OpenAI’s self-service campaign tool. Ads appear on Free and Go plans; Plus, Pro and Enterprise remain ad-free.

  • Paid space stays separate. OpenAI says ads do not influence ChatGPT’s answers and advertisers cannot read private conversations. More than 100,000 advertisers have tried campaigns since launch; that is a cumulative count, not today’s active customers.

  • Sales proof is still developing. OpenAI is expanding measurement, including early experiments to identify sales caused by advertising. A purchase recorded after an ad does not necessarily mean the ad created an extra sale.

MarketMaze Take: The expansion creates more room to test a sales channel. It does not establish what a typical merchant will earn from it.

  • Compare outcomes across markets. The portable question is whether conversational ads produce additional customers at an acceptable cost. More countries increase access; they do not answer that question.

  • Trials must become repeat budgets. Lifetime advertiser participation cannot show retention. Measurement improvements could build confidence, but evidence of recurring spending and representative sales results remains missing.

3️⃣ News

Meta’s average ad price rises 14% worldwide

The Maze: Meta, Facebook and Instagram's owner, grew quarterly advertising revenue 26% to US$63.06 billion. Advertisers need to separate that platform result from their own returns.

Meta Q3 2026 financial release: daily active people 3.64 billion, ad impressions up 10%, average price per ad up 14% year over year.

Source: Meta. Original Q3 2026 disclosures show worldwide ad impressions up 10% and average price per ad up 14% year over year.

The Details:

  • Displays and prices rose. Meta delivered 10% more ads worldwide in July–September. Its average price per ad rose 14% against a year earlier. That is total ad revenue divided by ads delivered, not a 14% increase in every advertiser's bill.

  • Markets diverged. The reported regional breakdown puts price growth at 23% in the US and Canada, 10% in Europe and 1% in Asia-Pacific. These are estimated locations of users receiving ads, not advertisers' home countries.

  • The cause remains partly unmeasured. Meta credits artificial intelligence with stronger advertising revenue. Its release does not quantify that contribution or establish whether an individual merchant earned more profit per customer order.

MarketMaze Take: For advertisers anywhere, Meta's revenue growth cannot settle whether buying its ads became a better deal. Higher delivery prices and better customer conversion can coexist.

  • Measure the outcome that pays. Compare actual campaign spending with profit from the orders it produces. An ad display is not a sale.

  • Keep geography in the calculation. The global average conceals wide regional differences. It cannot replace evidence from the market a campaign actually reaches.

4️⃣ Insight

Fresh food pulls ahead
Fresh shoppers buy more often
Fresh departments lead growth

The Maze: Fresh groceries could make Amazon a more frequent habit in the US. Perishables buyers spend more and shop more often, but the difference does not prove a causal benefit.

  • Fresh sales pull ahead. From August 2025 to August 2026, Amazon’s own perishables dollar sales rose 120.4%, versus 26.8% for shelf-stable goods and 21.9% for nonfood. These sales indices measure growth from each group’s starting level, not market share.

  • Several departments are accelerating. In the 12 weeks ending 29 August 2026, seafood sales grew 888.2% and produce 622.4% versus a year earlier, against 25.4% for traditional grocery. Fast growth can still start from small sales.

  • Fresh buyers return more often. In the 52 weeks ending 8 August 2026, 25.3% of US Amazon shoppers bought perishables. Their Amazon spending averaged $5,121 and 105 shopping occasions, versus $3,771 and 76 for the average buyer, who includes fresh buyers.

Why it matters: Repeat food purchases could bring more chances to sell other essentials. Brands should track repeat buying, while treating the shopper gap as association.

5️⃣ Insight

Seven channels: leaders versus other brands, from pure-play 71%/69% to agentic commerce 6%/3%.

The Maze: Brands put social shopping ahead of AI assistants in their channel priorities. The survey measures where teams plan to focus, not where future sales will land.

  • In Profitero+ findings, 31% of leading brands put social commerce, buying through social platforms, in their top two channels for understanding and growth over 12–36 months; only 6% chose agentic commerce, shopping with AI assistants.

  • Established online-focused retailers lead at 71% among leaders. Rapid local delivery reaches 47%, versus 36% among other brands: an 11 percentage-point difference in priority selections, not sales growth.

  • The 2026 benchmark surveyed over 200 ecommerce executives. Public materials omit geography and subgroup sizes, so leaders' answers cannot prove which channel choices cause success.

Why it matters: Keep core sales channels working while testing AI shopping on a small scale. Increase spending when customer results justify it, rather than treating interest as demand.

6️⃣ Insight

Six AI shopping task percentages: discovery 46, learning 55, comparing 63, basket building 33, support 39, replenishment 21.

The Maze: AI can help shoppers compare products without buying for them. A survey in France, Germany and the UK shows why retailers should treat those tasks differently.

  • Comparison records 63%, learning 55% and discovery 46% for AI use across shopping tasks in the previous three months. Clear product information helps an assistant explain the options.

  • Basket building records 33%, support 39% and replenishment 21%. These independent task responses measure neither a checkout funnel nor completed autonomous orders.

  • The December 2025 survey covers 749 people, but task-question routing is unclear. Its separate overall shopping-use figure is 38%; 63% must not become an all-shopper adoption claim.

Why it matters: Give assistants accurate specifications and availability to compare. Test that help before handing them buying authority; wider adoption remains unproven.
