Meta's Muse AI Agent Could Cost Apple $10 Billion in App Store Revenue, Analysts Warn

Meta's Muse Threatens Apple's $123 Billion Services Business

Meta's Muse AI agent has emerged as a significant threat to Apple's services revenue, with analysts warning of potential losses reaching $10 billion. Bank of America analyst Wamsi Mohan maintained a Buy rating on Apple with a $370 price target but cautioned that the company "can keep every handset sale and still lose discovery, referral, and transaction initiation."2

The risk centers on AI agents bypassing Apple's ecosystem entirely, capturing the economics that previously flowed through operating systems, search engines, and app stores.

Needham analyst Laura Martin calculated that if 40% of Apple's $123 billion in services revenue for fiscal year 2026 came from the App Store, and just 20% of that App Store revenue shifted to Meta's zero-fee Muse Connectors platform, Apple's revenue would drop by $10 billion and EBITDA would fall by $7.5 billion.1

This would directly threaten Apple's growth rate and valuation multiple, since annuity revenue streams command higher valuations than hardware sales. Apple shares dropped more than 2.5% following Bank of America's investor note.2

Muse's Rapid Adoption Signals Shifting User Behavior

Meta's Muse launched on September 8 and reached the top spot on Apple's U.S. App Store free apps chart within two weeks, amassing more than 3.4 million downloads according to Sensor Tower estimates.2

The AI agent can browse the web, fill out forms, book trips, send emails, and make purchases on behalf of users, all while running persistent background tasks on dedicated virtual machines in Meta's data centers.4

The platform received more than 1,500 developer applications within 168 hours of launching its Muse Connectors platform, signaling potential developer defections from Apple's ecosystem unless the company improves its economics for developers.1

Major commerce partners including Shopify, Expedia, and PayPal have already integrated with Muse, opening their full catalogs and payment systems to the agent.4

Shopify shares jumped more than 7% on the day its partnership was announced.5

AI Agents Reshape the Digital Subscription Economy

AI agents like Meta's Muse pose a broader threat to the digital subscription economy by actively auditing subscriptions and recommending cancellations. Bank of America analyst Tal Liani noted that "agents that actively audit subscriptions and recommend cancellations could make it easier for consumers and small businesses to eliminate low engagement software products that may have previously been forgotten about."1

If consumers and small businesses adopt personal AI agents at scale, it could introduce incremental churn headwinds across the subscription industry.

This matters because U.S. adults waste an average of $252 per year, or $21 per month, on unused subscriptions according to CNET's most recent annual subscription survey.1

AI agents could save consumers significant money while simultaneously pressuring businesses that rely on subscription revenue, particularly those in Apple's App Store ecosystem where forgotten subscriptions have historically contributed to steady revenue streams.

Siri Lags Behind in Critical Agentic AI Capabilities

Apple shipped a rebuilt Siri with iOS 27 on September 14, trained using custom Google Gemini models and Apple Foundation Models.4

However, Wamsi Mohan pointed out that Siri still lacks some of Muse's core capabilities, including persistent background tasks, broad third-party action support, and a dedicated agent payment rail.2

The development pace presents another challenge for Apple. The company typically ships major software updates once a year, while agentic AI platforms like Muse can improve daily.2

2

Mohan noted that modern iPhones already possess more than enough computing power to run AI agents, making software execution and integration the bigger hurdle. He argued that Apple needs its Services, silicon, payments, privacy, and Siri AI teams to move together more quickly if the company wants to compete for what he calls the "economics of user intent."2

Long-Term Strategic Risk Despite Near-Term Strength

While some analysts questioned whether Muse would materially impact App Store economics in the near term, noting that Apple only earns commissions on certain activities like gaming and in-game purchases rather than food delivery or airline bookings,3

the long-term strategic risk remains significant. Meta's enterprise ambitions, including its recruitment of the MongoDB CEO, suggest Muse could eventually reach further into commercial activity than initially expected.3

Bank of America forecasts Apple earnings per share of $8.85 for fiscal 2026, up 18.6%, and $9.46 for fiscal 2027, with a valuation multiple of 37 times its calendar 2027 EPS estimate of $9.98.4

Despite Apple ranking as the best-performing Mag-7 stock so far in 2026, and iPhone 18 Pro lead times remaining flat year over year even with 18% more premium units built,5

5

the threat from Meta's Muse and other AI agents represents a fundamental shift in how value flows through the mobile ecosystem. Apple's massive installed base and reputation for privacy remain important advantages, particularly when convincing users to trust AI agents with sensitive tasks, but the company faces mounting pressure to accelerate its AI agent development before losing control over discovery and transactions that currently drive its high-margin services business.
