Wall Street has become more bullish on Meta Platforms after the social media company launched Muse, an AI assistant that can send emails, book travel and complete transactions such as selling a car for users. Launched on Sept. 8, Muse offers a free basic tier alongside $20 and $100 monthly subscriptions for heavier use. The app is available on iOS and Android in the US and Canada, and recorded 2.8 million downloads in its first 12 days, according to Apptopia. On a comparable basis, Muse recorded 1.8 million downloads versus 1.3 million for OpenAI's ChatGPT over their respective first 12 days. Meta shares have risen more than 20% since the launch, adding over $200 billion in market capitalization and reaching their highest level in more than seven months as of the last close. Shares jumped more than 11% on Monday, helping drive a broader technology rally that lifted AMD and Intel, with AMD surpassing a $1 trillion valuation for the first time. J.P. Morgan analysts said Muse could become the most widely used consumer AI application since ChatGPT, citing its early product-market fit, Meta's distribution reach and free access. BofA Global Research said early reviews indicate that the assistant's ability to execute multi-step tasks with limited user intervention is resonating. Jefferies estimated that 1 billion users by the end of 2027, with at least 3% paying, could generate $10.8 billion in annualized revenue, and raised its Meta price target to $875. UBS Global Wealth Management said Muse offers early evidence that consumer AI agents could achieve broad adoption and create monetization opportunities beyond enterprise applications. Of 64 brokerages covering Meta, 57 rate the stock buy or higher, with a median price target of $760, according to LSEG data.
