Meta's AI agent Muse drives stock to best month since 2013
Meta Platforms shares jumped about 36% in September, reaching $777.59 and pushing market cap near $1.98 trillion. The surge followed the launch of the Muse AI agent, which became the top app on the Apple App Store. Analysts estimate Muse could generate up to $50 billion in annual revenue, leading to raised price targets.
Meta’s September rally erased its earlier 2026 losses, which had reached roughly 18% by mid-August amid investor concerns over heavy AI infrastructure spending. A legal settlement during that period helped ease sentiment before Muse’s launch. The app’s rapid rise to the top of Apple’s App Store followed its September 8 debut, with a single-day share jump of 11.34% on September 21. Analysts’ revenue projections for Muse, up to $50 billion annually, compare against Meta’s trailing advertising revenue of about $228 billion, suggesting the new business line could be substantial if partially realized. Upcoming earnings and the Connect developer event are seen as key catalysts.
The Muse-driven surge could reshape expectations for consumer AI adoption, showing that large user bases can quickly turn new tools into major revenue streams. If projections hold, Meta’s success may pressure competitors to accelerate similar launches, potentially intensifying AI investment across the tech sector. For everyday users, this could mean more integrated AI assistants in daily apps, but also raises questions about data use and market concentration. Investors and employees may see volatility, while regulators might scrutinize how such rapid growth affects competition and consumer choice.
