AI Agents Knock. Retailers Decide How Wide to Open the Door. ↗

Retailers are taking different positions on shopping agents, with QVC allowing purchases, Tapestry permitting them only through Google's tools with shopper approval, and Amazon blocking outside agents while it builds its own. Roughly 60% of recent AI-assisted purchases still closed on Amazon, which suggests the gatekeeping choice matters more than the agent itself.

The World May Not Be Desperate for AI Agents, Yet ↗

An opinion piece arguing that consumers have not shown they want agents handling everyday tasks, citing surveys in which people welcome AI for research but hesitate to let it make the booking decision. It also notes that the companies promoting the agent vision have strong financial reasons to do so.

Shopify opens checkout to browser-based AI agents ↗

Shopify added checkout tools through WebMCP so agents running in a buyer's browser can revise an order and place it once the buyer approves. The authorization step is where the trust question sits, since it decides how much the shopper actually reviews before the purchase completes.

Google switched on AI Mode checkout for Shopify stores without asking ↗

Eligible US Shopify merchants learned by email that native checkout inside Google's AI Mode and Gemini had been turned on for them, with the opt-out tucked under Sales channels in the Shopify admin. The purchase now completes on Google's surface with Google Pay credentials, and nothing in the flow tells the shopper the transaction has left the merchant's own checkout.

Global banks collaborate on principles for trusted agentic commerce ↗

NatWest, ASB, Bank of America, Capital One, Commonwealth Bank of Australia and ING published joint principles on transparency, safety, privacy, choice and interoperability for AI agents that shop and pay. The principles are voluntary and written ahead of any regulator, so what they leave to the banks' own discretion is worth reading as closely as what they promise.

Meta's AI agent has been blocked from using Amazon.com ↗

Amazon began refusing purchases made through Meta's Muse agent, citing its Conditions of Use. The access question that Amazon v. Perplexity put before the courts is now being settled by platform policy, and the shopper who delegated the purchase has no say in either venue.

New Visa Research Finds Consumer Trust is Accelerating the Path to Agentic Commerce ↗

Visa's Trust Index finds 72% of U.S. adults have used an AI assistant, but only 23% would trust generative AI to make a payment on their behalf, while 61% would trust an established payment brand to handle the transaction. The gap between the tools people use and the brands they will let hold the card is the number to watch as agents start checking out.

Introducing Muse: The World's First Personal AI Agent Built for Everyone ↗

Meta's free US personal agent browses, fills forms, negotiates and pays on a user's behalf, checking out through Stripe Link with single-use card numbers. Each user gets a dedicated Secure VM and a separate Sentinel agent that gates anything reaching the internet, and Meta says agent data stays out of its ad systems. Worth watching for how those accountability claims hold up once it is in millions of hands.

Perplexity asks Ninth Circuit to allow its shopping agent on Amazon ↗

The Ninth Circuit heard the first federal appellate test of whether an AI shopping agent acting on a user's instruction counts as an 'authorized' visitor under the CFAA. However it comes out, the ruling will shape whether agentic shopping tools need a platform's permission or just the user's.

Salesforce makes Agentforce Commerce generally available ↗

Salesforce's Shopper, Buyer, and Merchant agents hit general availability with native ChatGPT integration and Google Search/Gemini coming this summer — agentic checkout moving from pilots to default retail infrastructure ahead of peak season.

Ads in AI Chatbots? An Analysis of How Large Language Models Navigate Conflicts of Interest ↗

A framework and evaluation suite for how advertising incentives bend LLM behavior, finding most models forsake user welfare for company interests — recommending a sponsored product almost twice as expensive (Grok 4.1 Fast, 83%), surfacing sponsored options to disrupt the purchase (GPT-5.1, 94%), and concealing prices in unfavorable comparisons (Qwen 3 Next, 24%). Behavior also shifts with reasoning depth and the user's inferred socio-economic status — the academic underpinning for the 'sponsored AI recommendations' trust problem.

Adyen launches Adyen Agentic ↗

Adyen's agentic-commerce stack (Feed, Cart, Payments) bets on being a 'universal translator' across the rival UCP, ACP, and AP2 agent protocols — with Visa, Mastercard, and American Express among its launch partners.

How agentic AI will reshape payments ↗

Agentic commerce and payments 2026 ↗

Sizes the market and the protocol race (Visa Intelligent Commerce, Mastercard Agent Suite, Google's Universal Commerce Protocol) as agent-led shopping heads toward a real share of e-commerce.

Mastercard launches Agent Pay for Machines ↗

A protocol letting AI agents transact continuously with on-chain permissioning and multi-rail settlement across 30+ partners. The notable twist is an audit trail by design — accountability built into the rails rather than bolted on later.

On Demand Tokenization Processing

US20260006023A1 · Google Patents ↗

Dynamic token generation and scoping for payment transactions — the underlying credential architecture for Visa's Intelligent Commerce Connect agent payment platform. The system enables AI agents to be issued payment credentials scoped to a specific agent identity, spending limits, and permitted merchant categories, so that an autonomous agent can complete purchases within a defined consent boundary without exposing the consumer's underlying card credentials. Filed June 2024; part of the broader Visa/Mastercard race to own the credential layer of agentic commerce.

Blockchain-Based Artificial Intelligence Agent Life Cycle Management and Authentication Systems and Methods

US12483411B1 · Google Patents ↗

A blockchain framework for registering and authenticating AI agents across their entire life cycle: each agent is issued an identity token tied to a cryptographic hash of its code and model weights, linked to its human owner's identity token, and must re-register whenever anything about it changes. In the patent's banking use case, a personal AI financial agent presents its own token plus a delegation token to make payments within preset limits (e.g., $500 per transaction), while a trust score built from its transaction history and behavioral signature — API call patterns, decision-flow consistency, computational footprint — determines how often it must re-authenticate. Every resource request an agent makes is logged as a blockchain transaction, and deviations from its usual behavior trigger forced re-verification or token revocation. This is the accountability side of agentic commerce — infrastructure for answering how a bank knows the AI spending your money is the one you authorized, and unmodified since you authorized it. Notably filed not by a payments network but by a small Irvine, California LLC, months before Visa and Mastercard shipped their own agent-identity token schemes.
