Meta Shares Dip After AI Assistant Muse Launch

Meta Platforms Inc. (META) saw its shares trade with volatility following the introduction of Muse, a new autonomous AI assistant designed to perform proactive tasks across personal workflows. The stock opened with a modest gain of 1% before settling into a decline, closing at $613.48, a drop of $3.29 or -0.53%. After-hours trading saw a rebound, with shares rising to $618.48, an increase of $5.00 or +0.82%. The announcement sparked immediate market reactions, reflecting investor interest in Meta’s expanding AI ambitions amid a broader push toward generative AI solutions. Muse, unveiled by CEO Mark Zuckerberg, is a standalone AI agent capable of independently sending emails, booking travel, filling out web forms, and even resuming tasks after the app is closed. It operates with a layered security framework, including a dedicated virtual machine (Muse Secure VM), a secondary AI watchdog (Sentinel), and an upcoming premium tier (Muse Confidential VM) offering end-to-end data encryption controlled by user-held keys. The product is currently rolling out in the U.S. for free across iOS, Android, and the Muse.ai website. Future plans include premium subscription tiers and potential integration with AI glasses. Payment protections are being incorporated via Stripe’s Link, with future integrations planned for Shop Pay and 1Password. Zuckerberg emphasized user control, allowing selection of which apps Muse accesses and the ability to disconnect services at any time. For sensitive actions—such as purchases or emails—Muse requires explicit user approval before proceeding. The launch marks Meta’s latest step in its AI-first strategy, positioning Muse as a competitive offering alongside other proactive AI agents in development.
