This article was created with the help of artificial intelligence.
Key Takeaways
- Meta's AI agent Muse triggered a selloff in the financial sector on September 22 and 23, 2026, with the S&P 500 Financials Index falling nearly 2 percent to its lowest level since July.
- Goldman Sachs identified AT&T, T-Mobile, Allstate, Progressive, Netflix, Paramount Skydance, Expedia, and Booking Holdings as particularly at-risk companies whose business models rely on consumer switching inertia.
- Booking Holdings declined 2.6 percent on September 23, while bank stocks from JPMorgan, Wells Fargo, Bank of America, and Charles Schwab came under pressure.
- Citrini Research warned that AI agents could particularly hit the health insurance industry, where approval processes are deliberately made cumbersome and consumers spend an average of five hours obtaining coverage approval.
- Bloomberg Intelligence predicted that AI agents like Muse and Instinct would function as toll booths and generate revenue from transactions flowing through their platforms.
Meta's new personal AI agent "Muse" caused a massive selloff among financial services, insurance, and travel platform companies on September 22 and 23, 2026. The S&P 500 Financials Index fell nearly 2 percent on Tuesday, September 23, closing at its lowest level since July, while the broader S&P 500 remained virtually unchanged.
Banks and Brokers Under Pressure
In the banking sector, JPMorgan, Wells Fargo, and Bank of America recorded price declines. Charles Schwab was particularly affected, with its stock declining significantly in the selloff. In a note dated September 23, investment bank Goldman Sachs identified companies across multiple sectors that benefit from so-called "consumer inertia" — the tendency of customers to maintain existing business relationships due to inertia and switching costs, rather than genuine preference.
Muse reached number one in the U.S. Apple App Store on September 22 and can perform digital tasks on behalf of the user by connecting the application to third-party services such as Gmail or OpenTable. Investors' concern: AI agents could reduce friction in switching providers so significantly that business models based on this inertia would come under pressure.
Financial Services Firms Goldman Sachs Identifies as At-Risk
Goldman Sachs identified in its analysis specific sectors vulnerable to disruption by AI agents, should these improve at price comparisons, travel bookings, customer service, and handling recurring bills and negotiable rates. The bank listed the following companies as particularly at-risk:
- AT&T and T-Mobile U.S. in the telecommunications sector
- Allstate Corp. and Progressive Corp. in the insurance sector
- Netflix and Paramount Skydance in streaming
- Expedia and Booking Holdings in travel
Booking Holdings fell 2.6 percent on September 23. The European telecommunications sector was cited as the worst-performing sector during the selloff, according to source reports.
Insurers and Travel Platforms in Focus
Research firm Citrini Research published a critical report on Monday, September 22, on consumer adoption of AI agents. Analysts argued that consumers would begin to "question companies that benefit from transaction friction." The health insurance industry was particularly highlighted, where approval processes are deliberately designed to be cumbersome — such as "five hours to obtain coverage approval" — and AI agents could expose this margin creation.
Rhys Williams, Chief Strategist at Wayve Capital Management, called Muse on September 23 "undoubtedly negative for this type of company," but characterized the current impact as "more of a curiosity." For the future, he predicted: "In two years, we'll all have agents."
Parallels to Earlier AI-Driven Market Moves
Market reaction to Muse is reminiscent of an earlier AI-triggered selloff in February 2026. At that time, software-as-a-service companies suffered significant losses after Anthropic PBC launched agentic tools like Claude Cowork. Delivery, payments, and software firms were particularly affected at that time.
Bloomberg Intelligence warned in an assessment that personal AI agents have the "potential to draw customers away from established online platforms like Uber Technologies." Analysts Mandeep Singh and William Tong predicted that Muse and competing agents like Instinct would function as "toll booths" and generate revenue from transactions flowing through AI apps.
Citrini Research, which had already published a critical report in February, warned on September 23: "Tactics that worked when consumer behavior was shaped by human psychology will become obsolete."
Winners and Losers in the AI Agent Era
While financial services and insurance firms suffered losses, semiconductor stocks showed gains over the same period. Amazon blocked Muse from shopping on its platform and was rated by analysts as a strategic loser; the stock remained, according to source reports, "essentially flat for the week" through September 23.
The threat is not limited to Muse alone. With competing AI agents like Instinct, sector-wide disruption potential is growing. Goldman Sachs identified telecommunications companies and utilities alongside financial services as industries to watch if AI agents lower switching costs for consumers.
