Meta Stock Added $200 Billion But Its New AI May Not Scale

Meta’s stock has added nearly two hundred billion dollars in market value on the assumption that its new AI agent will scale. Yet early internal trials show that some Muse phone calls are still being handled by contractors through a “human concierge” feature — a detail Wall Street has largely treated as routine product development. It is central to the investment case because investors have priced in automation before knowing how much of the service is genuinely automated or what each completed task will ultimately cost Meta to deliver.

A Fast Launch With Big Expectations

Muse launched on Sept. 8 and quickly moved to the top of the U.S. app charts. It can send emails, arrange travel, shop online, complete forms and call businesses on behalf of users. More than 2.5 million downloads followed within roughly two weeks, and Meta shares jumped 11% in one session as investors started treating Muse as the consumer product that could finally explain the company’s enormous AI expenditure.

It’s no wonder people are excited. Meta has around 3.6 billion daily users across Facebook, Instagram, WhatsApp and Messenger. It is believed to be eyeing Muse subscriptions in the $20 to $100 a month range, which could produce billions of recurring revenue even with a modest conversion rate. The market has already done that calculation. The part it cannot yet calculate is what each paying customer will cost Meta to serve. I previously wrote that rapid adoption can create an extraordinary company while leaving investors uncertain about how much of the economics remain after computing, infrastructure and competition take their share.

The Cost Behind Meta Stock

Reuters reported that Meta is testing a human-concierge feature in which contractors handle some Muse calls. The trial has been offered to half of Meta’s employees on an opt-out basis, with the company describing it as a way to learn about safety and privacy before public release.
