Meta Shares Drop Following 35% Surge Due to Muse AI
META shares dropped from a peak of $779 to $715 after an investigation revealed that its Muse AI agent inadvertently disclosed a Facebook Marketplace seller's residential address, erasing $11 billion from CEO Mark Zuckerberg's net worth.
The Nasdaq-traded social media behemoth META experienced a remarkable 35% monthly rally. This momentum kicked off when Muse, its tailored AI agent, surged to the summit of the App Store following over three million user downloads. This milestone transformed market sentiment, pivoting the enterprise’s narrative from an “AI cash-burning laggard” to a “potential monetization leader.” Fueling this enthusiasm, the share price skyrocketed from a trough of $578 to a peak of $779 in September 2026.
Nevertheless, the very catalyst behind META’s meteoric ascent has now triggered a pullback this week. A recent investigation by the Guardian revealed that META’s Muse AI inadvertently disclosed a user’s residential address to a prospective Facebook Marketplace buyer. This incident ignited renewed anxieties regarding the application’s safety standards and its propensity to leak the private details of individuals listing items. The autonomous AI assistant instructed the buyer to travel directly to the seller’s residence for pickup, completely bypassing the seller’s awareness.
Following the publication of the report, META’s equity retreated from its $779 high down to $715 over the course of just two trading sessions. Concurrently, CEO Mark Zuckerberg saw his net worth diminish by $11 billion during this two-day market slide. Because the seller remained completely uninformed that Muse had shared their home address to finalize the transaction independently, investors are now expressing deep apprehension regarding the AI’s operational capabilities.
META Stock Under the Scanner For Privacy and Safety Concerns
Lingering data privacy questions surrounding Muse continue to breed investor hesitation toward META shares. Leadership under Zuckerberg must urgently address these vulnerabilities to secure user safety and confidentiality. Autonomous AI agents must not be permitted to execute transactions on behalf of sellers or distribute private home addresses simply in response to product inquiries. Failure to promptly manage and resolve this issue could push META stock down beneath the $690 threshold.
