Amazon Blocks Meta Muse as AI Agent Tops U.S. App Charts
Meta Muse has run into an early obstacle with one of the world’s largest online retailers after Amazon began blocking Meta’s new artificial intelligence agent from accessing its shopping site, just as the app surged to the top of U.S. mobile download charts.
The dispute goes beyond another chatbot launch. Muse is designed to act on a user’s behalf across the web, handling tasks ranging from online shopping and appointments to email, travel and other multi-step digital activities.
Why did Amazon block Meta Muse?
Amazon blocked Muse from its retail site after Meta declined a request to remove the agent from the shopping experience, according to Bloomberg News.
Amazon said companies cannot deploy automated shopping tools on its website without authorization and that access by an unauthorized AI agent violates its terms of use.
The move prevented Muse from carrying out shopping tasks on Amazon, creating one of the first major clashes between a large online marketplace and a consumer-facing AI agent designed to act independently on a user’s behalf.
The dispute raises a broader question as autonomous AI agents become more capable: who decides which agents can enter digital platforms and perform transactions for customers?
What is Meta Muse?
Meta launched Muse in the United States on September 8, 2026, describing it as a personal AI agent that goes beyond answering questions and can take actions on a user’s behalf.
According to Meta, Muse can send emails, book travel and appointments, browse the web, work with documents, connect to apps and services, and help users complete purchases.
Muse is available through a standalone mobile app and can also be accessed through Meta-owned WhatsApp, giving the service a distribution channel that extends beyond standalone app downloads.
Meta Muse tops U.S. app charts
Muse quickly rose to the top of the U.S. mobile charts after its launch.
As of Monday, September 21, Muse ranked as the No. 1 free application on both Apple’s U.S. App Store and Google Play, according to Bloomberg, citing Sensor Tower data.
The app recorded more than 902,000 downloads during its first six days, compared with roughly 773,000 downloads for the Meta AI app over the same period following its launch.
By September 22, Reuters reported that Muse had reached about 2.8 million downloads in the United States and Canada within 12 days, underlining the speed of its early adoption.
Those figures do not capture all Muse usage because the assistant is also available through WhatsApp.
Meta shares surge as investors embrace Muse
The early reception for Muse has also had a major impact on Meta’s stock.
Meta shares jumped more than 11% on Monday as investors responded to the assistant’s rapid adoption and renewed optimism around consumer artificial intelligence.
Reuters reported on Tuesday that Meta’s shares had gained more than 20% since Muse launched on September 8, adding more than $200 billion to the company’s market value.
Analysts have pointed to Muse as a potential new source of subscription, transaction and advertising revenue if Meta can convert its early adoption into sustained usage.
The rally comes amid broader investor enthusiasm for artificial intelligence. Profile News previously reported that AMD’s market value crossed the $1 trillion mark amid renewed AI optimism, highlighting continued investor interest in companies tied to AI infrastructure and computing.
How does Meta Muse work?
Meta says Muse operates inside a dedicated environment called Muse Secure VM, a virtual computer with its own browser that allows the agent to perform tasks across the web.
The company says users decide which services Muse can connect to and how much access the assistant receives.
Meta also says users remain in control of the agent and can determine what actions it is allowed to perform.
The system is powered by Muse Spark, which Meta describes as its most capable model for agentic work.
Muse moves beyond chatbot-style AI
Muse reflects a broader shift in artificial intelligence from tools that mainly answer questions or generate content toward systems capable of completing sequences of actions across websites and applications.
This category is often described as agentic AI.
Instead of simply recommending a hotel, restaurant or product, an AI agent can potentially search for options, compare them, fill out forms, make reservations and complete transactions.
That expanded capability also creates new questions about platform access, consumer consent, payment security, privacy and responsibility when an automated system makes a mistake.
Why Amazon’s decision matters
Amazon’s decision is particularly important because the company has its own artificial intelligence shopping products and tools.
If third-party AI agents increasingly become the interface customers use to find and buy products, retailers could lose part of the direct relationship they currently maintain with shoppers through their own websites and apps.
That gives large platforms a strong incentive to decide which outside agents can interact with their services and under what conditions.
The Meta-Amazon dispute therefore offers an early example of a broader competitive issue likely to emerge as AI agents become more widely used.
Banks warn about AI shopping risks
Financial institutions are also paying closer attention to agentic commerce.
A group of major banks, including Bank of America, Capital One, ING and Commonwealth Bank of Australia, warned on September 22 that AI shopping bots could create new risks involving scams, fraud, incorrect purchases and data privacy.
The banks said consumer protections and industry standards may need to evolve as AI systems gain greater ability to act independently during online purchases.
What does Amazon’s Muse block mean?
Amazon’s decision does not shut down Muse or prevent it from performing tasks elsewhere on the web.
It does, however, show that the success of personal AI agents will depend not only on their technical capabilities but also on whether major digital platforms allow them to operate inside their ecosystems.
The next phase of the AI race may therefore involve more than building the most capable model. It could also center on which agents gain access to the websites, marketplaces and services people use every day.
With Muse rapidly expanding its user base less than two weeks after launch, its ability to maintain momentum while navigating platform restrictions will be an important test of Meta’s strategy in personal artificial intelligence.
