Meta launched its personal AI agent, Muse, on September 8, 2026. Within two weeks, the application reached 2.5 million downloads in the US, topping the Apple App Store charts. Meta shares rose more than 20% since the launch, with an 11.43% increase on September 21.
Muse automates tasks such as travel booking and financial management. It integrates with over 500 airlines via the Duffel API, allowing users to book flights without visiting platforms like Expedia or Booking Holdings.
On September 22, market concerns regarding AI displacement led to a decline in stock prices for several companies. Expedia shares fell 3.7%, and Booking Holdings dropped 3.9%. The S&P 500 Financials Index slid up to 2.4%.
Financial institutions also saw losses, with JPMorgan and Wells Fargo shares falling more than 2.5%, while Allstate and Charles Schwab dropped over 5%. Wolfe Research estimates the addressable market for AI agents in travel and finance at $30 billion to $50 billion.
