Meta launched Muse an agentic AI assistant that can browse e-commerce sites, compare prices, and complete purchases after a simple user approval. Within weeks the app vaulted to the top of the U.S. App Store, amassing over five million downloads and three million weekly active users. Early adopters report that Muse handles everything from obscure skincare formulas to discontinued Levi’s jeans, allowing them to skip the traditional search-and-click routine. The experience is deliberately frictionless: the user selects a product, Muse presents options, and the shopper merely confirms the payment before the transaction is finalized.
Rapid uptake and real-world feedback
Leif Abraham, co-founder of the investment platform Public, shared that Muse has become his go-to tool for niche purchases. He noted a noticeable dip in his Amazon order volume after redirecting the AI to buy directly from brand-owned stores. Abraham’s X post highlighted a “win for Shopify” after Meta announced a checkout integration that lets Muse customers settle purchases through Shop Pay on Shopify merchants. While Abraham calls himself an “Amazon mega-user,” he now reserves the marketplace for low-research items like household staples, preferring Muse for products that demand more detailed vetting.
Other tech-savvy users echo his enthusiasm, yet results are uneven. Some have struggled to secure tickets for limited-run events, indicating that Muse’s capability still hinges on product availability and the complexity of the request. Nonetheless, the growing chorus of success stories fuels confidence that consumers will increasingly delegate buying decisions to AI agents.
Retail giants react: Amazon blocks, Shopify embraces
Amazon responded to Muse’s ascent by prohibiting the assistant from placing orders on its platform, citing concerns over credential handling and data scraping. The restriction could deprive Amazon of a burgeoning stream of sales if Muse gains wider traction. In contrast, Shopify partnered with Meta to enable seamless checkout via Shop Pay, effectively converting Muse’s product recommendations into direct merchant revenue. Shopify CEO Tobi Lütke amplified this narrative by resharing Abraham’s post, noting that multiple users are already reporting a shift away from Amazon in favor of brand-direct purchases.
From an investor perspective, the divergence is already reflected in market movements. Since Muse’s debut, Meta’s stock has risen more than 17%, while companies dependent on consumer inertia—such as Planet Fitness, Booking Holdings, SiriusXM, and Charles Schwab—have seen double-digit declines. Conversely, retailer-focused stocks like TJX and Costco posted gains of roughly eight percent and four percent respectively, whereas Amazon slipped only about one percent, outpacing the S&P 500’s modest rise.
Why Amazon may still hold its ground
Analysts argue that Amazon’s extensive inventory, rapid fulfillment network, and the Prime ecosystem create a defensive moat. Even if external agents like Muse recommend products sold on Amazon, the e-commerce giant can still capture the final transaction and the valuable first-party data that feed its advertising arm. Amazon’s own Alexa for Shopping assistant already processes over 350 million users, offering price alerts and auto-buy features that boost average order values by 40 %.
The real strategic risk lies in the potential decoupling of the shopper from Amazon’s platform. If an AI agent routes a purchase to a third-party merchant, Amazon may lose the associated advertising dollars, even though the sale itself could be fulfilled by its logistics. Monitoring metrics such as advertising revenue growth, seller fee structures, and Prime pricing will be essential to gauge how much of the ecommerce value chain remains under Amazon’s control.
Outlook for the retail sector
Agentic AI like Muse is still in its infancy, but the trend hints at a future where consumers move from “search and shop” to “delegate and approve.” Companies that provide transparent pricing, broad product selections, and fast delivery are better positioned to stay relevant as the technology matures. Meanwhile, platforms that tightly integrate AI agents into their checkout flow—Shopify being a prime example—stand to capture new revenue streams both from merchant fees and from the data generated by AI-driven recommendations.
For investors, the takeaway is nuanced. While Amazon’s sheer scale may buffer immediate disruption, any erosion of its data moat could pressure its lucrative advertising business. Retailers that excel at membership loyalty (e.g., Costco) and those that swiftly adopt AI-enabled checkout experiences (e.g., Shopify merchants) could see amplified upside as consumers grow comfortable handing purchasing power to autonomous assistants.
