Bank of America's Mohan sizes the Meta Muse threat to Apple's App Store at up to $10 billion

Apple typically keeps 30% of an App Store transaction ^[4]. At that rate, losing up to $10 billion of commission ^[1] means agents redirecting roughly $33 billion of spending that would otherwise pass through Apple ^[1]. Set against Muse's estimated 2.5 million to 3.4 million downloads in its first two weeks ^[11], the ceiling comes to about $2,900 to $4,000 of Apple commission per copy installed ^[2]. That is a sum about AI agents as a category. Muse is one app, a few weeks old ^[7]. Crypto Briefing, which relays the $10 billion from CNBC's reporting, calls it a ceiling, not a forecast ^[14].

Mohan's case turns on where a purchase begins ^[2]. He wrote that agents like Muse could redirect "discovery, referral, and transaction initiation" ^[3]. Muse runs on a secure virtual machine in Meta's cloud and keeps working in the background when it is off screen ^[10]. By Crypto Briefing's account, the heavy lifting happens outside the iPhone's app framework, so Apple controls the device while the transaction can happen somewhere else ^[16]. The same agent climbed to the top of the US App Store's free chart ^[17].

The coverage describes the exposure as Apple's subscription revenue ^[1]. Muse's hooks are into retail checkout, travel reservations and payments ^[8]. The reports do not say how one turns into the other, or over what period the $10 billion would be lost.

This could go a few ways. If the launch-week installs never become daily habits, the ceiling stays on paper; Crypto Briefing makes the same point, that sustained use will matter far more than launch-week curiosity ^[18]. Merchants refusing access would leave the agent with less to buy on anyone's behalf ^[9]. Apple only loses real money in the case Crypto Briefing's report describes, where agents end up dictating merchant relationships and capturing routing economics independent of App Store revenue ^[15].

I think merchant access matters more to Apple than downloads. An agent can only route a purchase that a merchant lets it complete. The counter-case is that Shopify, Expedia and PayPal have already connected ^[8], and an agent that keeps executing in the background on Meta's servers ^[10] does not need the user to open anything. Two things would show the merchant-access view is too cautious: Muse holding daily use well past its launch, and a large retailer that keeps it out today deciding to let it in.
