Meta's Muse AI Agent Has Wiped Billions From Consumer Stocks Since Its September Launch

Meta's Muse AI agent has triggered a broad sell-off in consumer-facing stocks since its September 8 launch, as Wall Street bets that autonomous software capable of canceling subscriptions and comparing prices on behalf of users will erode the business models of companies that depend on customer inertia.

The trade, which analysts have dubbed "consumer inertia," has hammered a wide range of names over the past three weeks. Planet Fitness has fallen 20% since Muse launched. Travel stocks Airbnb and Booking Holdings are down 13% and 16%, respectively. SiriusXM has dropped approximately 11%, and brokerage Charles Schwab has slipped 9%.

The thesis holds that agentic AI tools like Muse could actively work on behalf of consumers — comparing prices, canceling unused subscriptions, and routing around intermediaries — undermining businesses whose revenue relies on customers who simply do not bother to act.

CNBC's Jim Cramer pushed back on that framing Tuesday, arguing that investors are applying the disruption thesis too broadly and creating potential buying opportunities in companies whose underlying businesses remain intact.

"I'm skeptical about dumping entire groups based on this idea that agentic AI means the death of consumer inertia and companies that benefit from it," Cramer said. "Right now, it feels like some proverbial babies are being thrown out with the bathwater, and that often makes for good buying opportunities."

Cramer drew a parallel to what he called the "SaaSpocalypse" earlier this year, when enterprise software stocks sold off sharply on fears that AI would disrupt per-seat pricing models or allow companies to build their own tools. That sell-off eventually abated, and names with strong track records — he cited Salesforce — recovered.

Whether the consumer-inertia trade follows a similar arc remains unclear. Cramer acknowledged that Muse is having a real impact on some businesses, but argued that investors should assess each company's vulnerability individually rather than treating entire sectors as casualties.

On gyms, Cramer pointed to Life Time as a company whose upscale, highly engaged membership base makes mass cancellations less likely. Its shares are down 7% since Muse launched — notably less than the 20% decline at lower-cost Planet Fitness, where member engagement may be weaker.

On travel, Cramer noted that online travel agencies offer loyalty rewards and comparison tools that retain value even in an agentic AI environment. He also noted that Expedia has announced a partnership with Muse directly. "Airbnb's sold off dramatically in the last month, to the point where I think the stock's a steal," Cramer said.

He was more cautious about SiriusXM, arguing the satellite radio company had been in secular decline long before agentic AI became a factor.

"I don't think [Muse] will destroy entire industries, but there are plenty of companies that could be vulnerable here," Cramer said.

The consumer-inertia sell-off reflects a broader pattern of market volatility around AI product launches, underscoring how quickly investor sentiment can reprice entire sectors when a new agentic capability is introduced — regardless of whether the underlying competitive threat has been fully validated.
