Meta Platforms (META) stock surged roughly 25% in September 2026, marking its strongest monthly performance in more than a decade.
The rally was driven almost entirely by the launch of Muse, Meta’s new personal AI assistant designed to handle everyday tasks for users.
Muse debuted on September 8 with free and paid subscription tiers priced at $20 and $100 per month, depending on usage levels.
Meta described Muse as a “widely available personal AI agent” capable of helping users shop, organize trips, write emails, and manage daily tasks.
The app reached number one in the US Apple App Store’s free apps category within its first week, outpacing ChatGPT in the rankings.
The stock rally did not build gradually but accelerated sharply once Muse hit the market, signaling that investors viewed the app as meaningful product traction.
Subscription revenue from Muse offers Meta a potential income stream separate from its core online advertising business, which has long dominated the company’s financials.
Wall Street analysts responded swiftly, with Wells Fargo raising its Meta price target to $796 and Goldman Sachs and Morgan Stanley flagging Muse as a turning point in Meta’s broader AI strategy.
J.P. Morgan upgraded Meta Platforms to Buy and raised its price target to $820 from $640, citing early traction with the Muse AI agent as a key driver of the decision.
Investors have spent much of the past several years debating whether Meta’s heavy spending on chips, data centers, and AI infrastructure would generate meaningful returns.
Muse’s early commercial success appears to be shifting that conversation, giving Wall Street a tangible product to point to when evaluating the company’s enormous AI bets.
The launch also arrives against a complicated backdrop for Meta, as broader societal concerns around AI safety and cybersecurity risks continue to intensify across the technology sector.
Meta recently agreed to pay roughly $17 billion to settle with a coalition of state attorneys general that had sued the company over alleged harms to children caused by Facebook and Instagram.
Despite that legal and reputational pressure, investors appear focused squarely on Muse’s early momentum and what it could mean for Meta’s long-term revenue diversification strategy.
