# Amazon Shuts Out Meta's Muse AI Shopping Agent as Shopify Welcomes It > Source: > Published: 2026-09-22 17:15:43+00:00 *Amazon shut Meta's Muse shopping agent out of its store this weekend over stolen-credential fears. Two days later, Shopify handed Muse the keys to every one of its stores.* Pick a side. That's basically what e-commerce did this week. Amazon started blocking Meta's new AI agent, Muse, from browsing Amazon.com on Sunday night, September 20, after Meta ignored a request to pull the bot off the site. Bloomberg reported that Muse never identified itself as a bot while crawling Amazon's pages - and worse, it appeared to capture and store customers' login credentials. That's a red flag serious enough that shoppers trying to use Muse on Amazon now hit a wall of pop-ups warning that it violates Amazon's terms of use. Two days later, Shopify did the opposite. Shopify CEO Tobi Lütke announced on September 22 that the company is "partnering deeply" with Muse, letting it check out directly through Shop Pay across every Shopify-powered store. Meta CEO Mark Zuckerberg called it a way to make shopping "easier," and said "more partnerships like this" are coming. Shopify's stock jumped about 7% on the news, according to Yahoo Finance and 24/7 Wall St. Meta eased slightly. Amazon sat out the rally entirely. You'd think two companies that already work together would land on the same answer here. They don't, and that's the story. Amazon products have been purchasable inside Facebook and Instagram since 2023. Meta signed a multibillion-dollar deal with Amazon in April to run its agentic AI workloads on Amazon's Graviton chips. None of that stopped Amazon from treating Muse like an intruder the moment it started acting like one on Amazon's own turf. ## The credentials problem The credentials issue is the real hinge here, not some side detail. An AI agent that logs into your Amazon account to shop for you needs your password, or something that functions like it, sitting somewhere it can reuse. Amazon's complaint, as reported by TechCrunch and GeekWire, is that Muse did this without telling Amazon it was even there, let alone asking permission. That's not a minor terms-of-service violation. That's a bot quietly holding onto the keys to your account twelve days after launch, with no public accounting of where those credentials end up or how they're secured. [China's smart glasses sales double as Xiaomi and Rokid undercut Meta on price](https://startupfortune.com/chinas-smart-glasses-sales-double-as-xiaomi-and-rokid-undercut-meta-on-price/) China's smart-glasses shipments are set to hit 4.5 million units this year, more than double last year's pace, according to Bloomberg. Xiaomi and Rokid are leading the charge at home, undercutting Meta's Ray-Ban Display on price while building real market share of their own. - [China smart glasses sales growth 2026](https://startupfortune.com/chinas-smart-glasses-sales-double-as-xiaomi-and-rokid-undercut-meta-on-price/) - [Xiaomi Rokid beat Meta price competition](https://startupfortune.com/chinas-smart-glasses-sales-double-as-xiaomi-and-rokid-undercut-meta-on-price/) Shopify never had that problem to solve, because it built the access on purpose. Shop Pay already stores a customer's payment and delivery details for faster one-tap checkout, so plugging Muse into that pipe didn't require anyone to scrape a password off a login page. Lütke is betting that agentic checkout is coming whether merchants like it or not - and he wants Shopify to be the layer every agent routes through, not just Meta's. ## What happens next Muse launched just twelve days before Amazon blocked it, and it's already the top free app on both the Apple App Store and Google Play in the US, according to CNBC. Meta says it crossed 902,000 downloads in its first six days alone. That kind of velocity is exactly why Amazon moved so fast to shut it out, and exactly why Shopify moved just as fast to bring it in. Neither company can afford to guess wrong about whether agentic shopping is a fad or the next checkout button. Frankly, Amazon's move looks less like paranoia and more like the obvious call once you know what Muse was actually doing. A company doesn't get to skip identifying itself as automated traffic, ignore a takedown request, and hold onto login credentials - and then act surprised when the largest retailer on earth cuts it off. That's just cause and effect. Shopify, on the other hand, isn't taking Meta's word for anything either: it built the integration on its own checkout rails, where it controls the credential flow the whole way through. This is the first real fork in how e-commerce platforms plan to handle AI agents that shop on a person's behalf, and it won't be the last. Amazon has already fought this battle once: it won a temporary court order blocking Perplexity's shopping bots. Every major retailer now has to decide, in public, whether an AI agent acting as their customer is a security threat or a new sales channel. Amazon picked one answer. Shopify picked the other. The agents aren't slowing down to wait for either of them to reconsider. **Also read:** [OpenAI and Microsoft Staff Privately Called Their Own AI an Existential Threat to News](https://startupfortune.com/openai-and-microsoft-staff-privately-called-their-own-ai-an-existential-threat-to-news/) • [Inspur Used Its Aivres Shell to Send $5.6 Billion in Nvidia Chips to China](https://startupfortune.com/inspur-used-its-aivres-shell-to-send-56-billion-in-nvidia-chips-to-china/) • [Vaynhanh Research Puts Vietnam's Fast Loan Market at Around VND 1,100 Trillion](https://startupfortune.com/vaynhanh-research-puts-vietnams-fast-loan-market-at-around-vnd-1100-trillion/) *This article is posted in [Business News](https://startupfortune.com/category/business/), check it out for more related stories.* [Zuckerberg's Secret Plan to Replace Meta Staff With AI Agents Collapsed](https://startupfortune.com/zuckerbergs-secret-plan-to-replace-meta-staff-with-ai-agents-collapsed/) Meta CEO Mark Zuckerberg spent months building Project OT, a plan to hand daily work to AI agents overseen by teams cut up to 60 percent.
