Who Owns the Customer When AI Shops?

Every major interface shift in digital commerce redistributes bargaining power. Search engines became indispensable because they controlled discovery. Marketplaces aggregated demand and then monetized their position between buyers and sellers. Mobile operating systems controlled distribution and payment rules.

AI shopping creates another intermediary, but one with an unusual degree of influence. If the assistant interprets the need, chooses the shortlist and eventually initiates checkout, it can shape the transaction before the retailer sees the customer.

The question is not simply who processes the order. It is who controls each component of the customer relationship: attention, recommendation, identity, transaction data, service and loyalty.

Retailers want the traffic and fear the intermediation

Reuters captured the tension clearly in August 2026. Retailers including Walmart, Ulta Beauty and Wayfair are adapting to AI-driven shopping traffic while trying to keep the eventual purchase in environments where they retain behavioural data and loyalty signals. According to Adobe data cited by Reuters, AI-referred visitors were generating higher revenue per visit, making the channel difficult to ignore.

The architecture of current commerce protocols partially accommodates this concern. OpenAI’s ACP leaves the merchant as merchant of record. Shopify distributes merchant products into AI surfaces while centralizing management in Shopify. Visa’s current agentic-commerce offering emphasizes that customers can complete purchases on the retailer’s storefront so the merchant retains transaction visibility and the brand relationship.

These are not incidental implementation details. They are negotiations over who owns which part of the funnel.

The Amazon-Perplexity dispute is a platform-economics case

The legal fight between Amazon and Perplexity makes the underlying conflict unusually visible. In August 2026 a US appeals court overturned a preliminary injunction that had restricted Perplexity’s AI shopping tools on Amazon. The panel held that Amazon was unlikely to succeed on its claim under federal computer-access law at that stage.

The case will be studied for its legal treatment of agents acting on behalf of users, but the economic conflict is just as interesting. A third-party agent can potentially use Amazon for inventory and fulfillment while bypassing parts of the interface where Amazon controls sponsored placements, recommendation logic and comparison.

That is a novel form of disintermediation. The transaction can remain on the platform while the customer’s cognition moves elsewhere.

The customer relationship will fragment

There is unlikely to be one winner across the whole stack. AI platforms want complete product coverage and low-friction transaction access. Retailers want incremental demand without becoming anonymous fulfillment providers. Commerce platforms want to make merchants available everywhere while becoming the indispensable infrastructure underneath them.

The rational retailer response is optionality. Be discoverable in external agent environments, but keep product truth and commercial state authoritative. Make loyalty and identity portable where it creates value. Avoid depending on one agent for demand. Measure not only traffic but which systems are shaping the consideration set.

The phrase “own the customer” was always imprecise. A retailer can own the transaction and lose discovery; a platform can own attention and never fulfil the order. Agentic commerce makes that fragmentation more explicit.

The strategically important question is not whether AI intermediates the journey. It is which parts of the relationship a merchant can afford to let it intermediate.

A platform can lose part of the customer relationship even when the transaction never leaves the platform.

“The ruling is the first by a federal appeals court to address whether AI agents acting on behalf of users can legally access online platforms.” — Reuters
