On September 20, 2026, Amazon began blocking Meta’s Muse AI assistant, which Meta had launched on September 8. Muse is an AI shopping agent: it can browse and buy for its user. Amazon decided it would not be doing that on Amazon.com.
PYMNTS reported that on September 21 Shopify CEO Tobias Lütke announced a partnership with Muse. “We are excited to announce we are partnering deeply with Muse to enable agentic checkout with Shop Pay on all Shopify stores,” he wrote. Meta’s chief AI officer, Alexandr Wang, echoed the same line back at him.
Amazon and Shopify took different public positions on the same AI shopping agent in the same week. An AI shopping agent is software that browses and buys on a person’s behalf. If you sell on Amazon, on Shopify, or on both, the sources reviewed here do not measure how this will affect your sales.
Amazon says it blocked Muse over consent, identification and privacy and security.

Quick answers
Why did Amazon block Meta’s Muse AI agent?
Amazon says Meta never requested permission for Muse to shop on its site and that the agent doesn’t identify itself while browsing. PYMNTS reported Amazon saying the agent could create privacy and security risks if it captures and stores customer credentials.
Can AI agents shop on Amazon in 2026?
Amazon has blocked Meta’s Muse, and users who ask Muse to buy on Amazon.com see a notice that access by an unauthorized AI agent violates Amazon’s Conditions of Use (Tech Times, September 23, 2026). This page has not verified Amazon’s stance toward other AI agents.
Should my store let AI shopping agents in?
This page does not establish whether a particular Shopify store is enrolled in AI shopping channels. Shopify’s March 24, 2026 post said merchants can sell in surfaces such as Microsoft Copilot and, in select cases, Google’s AI Mode and the Gemini app. Check your own sales channels and Shop Pay settings.
What actually happened between Amazon, Meta, and Shopify
Meta shipped Muse on September 8, 2026, describing it as a personal AI agent (PYMNTS).
On September 20, Amazon began blocking it. A company spokesperson framed the move as a matter of basic manners between businesses: “We think it’s fairly straightforward that third-party applications that offer to make purchases on behalf of customers from other businesses should operate openly and respect service provider decisions about whether or not to participate.” Amazon cited the lack of advance notice and authorization, and that Muse does not identify itself as an AI agent. PYMNTS reported Amazon saying the agent could create privacy and security risks if it captures and stores customer credentials.
PYMNTS reported that on September 21 Shopify announced a partnership with Muse to enable agentic checkout with Shop Pay on all Shopify stores. Shop Pay had already passed $400 billion in lifetime accelerated gross merchandise volume by June 2026.
Why did Amazon block Meta’s Muse AI agent?
Amazon’s stated reasons are consent, identification, and privacy and security. Tech Times reported that Amazon gave Meta no advance notice, did not authorize Muse to access its checkout flow, and formally asked Meta to exclude Amazon from Muse, and that Meta declined.
For context, in its Q2 2026 earnings commentary, Amazon reported $19.8 billion in advertising revenue, up 26% year over year, and said Sponsored Products continues to be its largest ad offering. Amazon’s post quotes Andy Jassy on Amazon’s own Alexa+ and Alexa for Shopping experiences: “Shoppers who click a Sponsored Prompt convert to a sale 48% more often and spent 21% more on average than those who don’t.” That statistic is about Amazon’s own conversational shopping, not about Muse, and Amazon did not cite advertising as a reason for the block. Some commentary links the block to Amazon’s advertising business. Whether that is a motive is not established by the sources reviewed here.
Amazon’s own agent plays by the opposite rule
Tech Times reported that Amazon’s own Buy for Me agent shops other retailers’ sites on a shopper’s behalf, and that retailers have to opt out by email. The article’s argument is that the consent standard Amazon invokes against Muse is one its own agent does not meet. Amazon’s response to that argument is not covered in the sources reviewed here.
What Shopify said and did
PYMNTS reported that Shopify CEO Tobias Lütke announced the Muse partnership on September 21, 2026. Shopify has not been quoted in the sources reviewed as explaining its reasons beyond that announcement. PYMNTS quoted Shopify CFO Jeff Hoffmeister, speaking September 10, saying that starting with an LLM makes shoppers “2.5x more likely to end up right on the project page rather than starting somewhere in a general spot on the merchant’s website,” and “You’re going straight to the product you want, and then that leads to an uplift in conversion. We’ve seen roughly an 80% uplift in conversion.”
Shopify’s March 24, 2026 post said merchants were selling in Microsoft Copilot and, in select cases, in Google’s AI Mode and the Gemini app, using the Universal Commerce Protocol (UCP), which Shopify says it co-developed with Google. Shopify listed Walmart, Target, Etsy, American Express, Mastercard, Stripe and Visa as UCP supporters. The post also quotes Mani Fazeli, VP Product at Shopify: “Agentic commerce isn’t something we’re reacting to… It’s a vision we’re bringing to life at the very frontier of commerce and AI.”

What might AI shopping agents mean for online sellers?
The sources reviewed here do not measure the effect on sellers. The points below are the author’s practical suggestions, not reported findings. One is that sales an assistant influences may show up in analytics as search or direct traffic. Anyone selling online may already have some orders they cannot attribute.
Practical suggestions for online sellers
These are the author’s suggestions, not findings from the sources above.
Fix the product data first. Accurate, structured product details are useful whoever or whatever reads them. Materials, dimensions, compatibility, stock status, and current price need to be accurate and machine-readable across every channel. We covered related ideas in our look at where agentic AI is heading.
Check what you’re already enrolled in. Shopify merchants may be live in agent channels through platform-level settings rather than anything they switched on. Audit your sales channels, your Shop Pay configuration, and your Shopify Catalog presence before assuming you’ve opted out of anything. If you’re building custom surface area, the mechanics are worth understanding at the app and API level too.
Tag revenue by channel now, not later. If you can, record which sales channel each order came from at the point of sale, so any change in where orders originate is easier to see later.
Stress-test your dependence on a single marketplace. If most of your revenue depends on one marketplace, it is worth having a direct relationship with customers too. Related reading: running a leaner operation with AI tooling
