Meta Platforms (META) shares jumped over 11% during Monday’s trading session as Wall Street responded enthusiastically to the swift consumer embrace of Muse, the company’s latest AI-powered assistant. This represented Meta’s strongest single-day performance since April 2025, driving the stock to an 11-month peak closing price.
Since its September 8 debut, Muse has climbed rapidly up app store rankings across the United States. According to Sensor Tower data referenced by Bank of America analysts, the platform accumulated approximately 2.5 million U.S. downloads by September 19, maintaining around 557,000 daily active users.
Unlike traditional conversational AI tools, Muse functions as a task-oriented agent capable of executing actions for users. The platform can navigate websites, manage email correspondence, arrange travel accommodations, and execute purchases following user confirmation.
This expanded functionality is reshaping investor sentiment around Meta’s ability to develop a consumer-facing AI product that supports substantial subscription revenue. Reuters Breakingviews analysis suggested that widespread paid adoption of Muse might deliver approximately $24 billion in new revenue under certain conditions.
Amazon’s Blockade Highlights Platform Dependency Risks
Muse’s explosive early momentum has already generated tension with Amazon. The e-commerce giant prevented Muse from facilitating transactions on Amazon.com, citing Meta’s failure to obtain proper authorization for account access, data collection, or payment processing.
When users now attempt Amazon shopping through Muse, they encounter warnings that unauthorized AI agent usage violates the platform’s service terms. Amazon maintains that third-party shopping assistants must properly identify themselves and honor platform decisions regarding participation.
This conflict extends beyond a single merchant relationship. AI-powered shopping agents pose a fundamental threat by positioning themselves between consumers and retailers, potentially diminishing merchant control over customer engagement, product visibility, and advertising opportunities.
Having developed its own AI shopping capabilities and previously clashing with Perplexity over similar issues, Amazon has adopted a markedly different stance than certain other major commerce platforms.
Shopify has taken the opposite approach by welcoming Muse integration. The partnership enables Muse users to browse Shopify’s merchant network and finalize transactions through Shop Pay.
Muse Represents Potential Revenue Diversification
Truist analyst Youssef Squali forecasts that Muse might contribute approximately $28.5 billion in incremental revenue by 2030 if power users migrate to premium subscription tiers. He characterized the product as Meta’s most substantial effort to establish significant revenue beyond advertising.
This development carries weight because Meta’s primary operations remain overwhelmingly reliant on advertising income. A thriving subscription-driven AI assistant would provide the company with a fresh stream of predictable consumer revenue.
Muse’s promising debut is also prompting investors to reconsider Meta’s substantial AI capital expenditures. Meta intends to deploy significant resources toward data infrastructure, semiconductor technology, and model research, and the stock had previously experienced pressure over concerns about return on these investments.
Significant obstacles remain ahead. Early user excitement doesn’t automatically translate to sustained engagement, and platforms like Amazon maintain the power to restrict Muse’s most valuable features.
User trust presents another challenge, as agents managing emails, completing purchases, and coordinating travel require access to highly sensitive personal data. Meta is currently testing enhanced features, including human concierge support for certain Muse phone interactions, which has generated internal discussions about privacy safeguards.
The cautionary note for investors is that META shares have already experienced a sharp rally based on preliminary adoption metrics. Should Muse growth decelerate, paid conversion rates disappoint, or additional major platforms implement Amazon-style restrictions, market expectations could contract rapidly.
Nevertheless, Muse is currently bolstering Meta’s AI investment narrative. The application has secured leading positions in app store rankings, accumulated millions of downloads, and contributed nearly $200 billion to Meta’s market capitalization in one trading day.
