Meta shares rose by approximately 25% in September 2026, marking the company's best monthly performance in over two years. This growth included a 7% single-day increase, following a 38% rise from March lows. Financial institutions including Goldman Sachs, Wells Fargo, and Morgan Stanley identified the launch as a significant shift in Meta's AI strategy.

The company released its personal AI assistant, Muse, on September 8. The application offers a free version alongside paid tiers priced at $20 and $100 per month. The $20 subscription is aimed at individual consumers, while the $100 tier is designed for professionals and small businesses. Wells Fargo subsequently raised its price target for Meta stock to $796.

Muse reached the top position in the US Apple App Store's free apps category within one week of its release, surpassing competitors like ChatGPT. The application focuses on autonomous task execution, such as managing emails, booking reservations, and negotiating online purchases. It integrates with third-party services including Gmail and Spotify to perform multistep actions.

Mark Zuckerberg describes the development of Muse as a step toward personal superintelligence. The company aims to create an AI capable of acting on behalf of users across the internet. This momentum arrives ahead of the annual Meta Connect event, where the company is expected to present its updated technological roadmap.
