Meta Platforms shares rose more than 5% on Wednesday, with one market update reporting a gain of more than 6%, after the company introduced Muse, a personal AI agent that can complete tasks including sending emails, arranging travel and making purchases. Mizuho Securities said the consumer agent could begin a substantial Meta product cycle not reflected in the stock, maintaining an Outperform rating and a $750 price target. KeyBanc Capital Markets holds an Overweight rating and a $780 target, saying the market underestimates Meta's AI position and product cycle. Meta shares had recovered most of their earlier-year losses and were down roughly 1% year to date before the move. Muse is available through a dedicated app, the muse.ai web portal and WhatsApp, where Meta says interactions work like messaging another person. CEO Mark Zuckerberg said Muse uses a Secure Credential Store that prevents the assistant from reading passwords and credit-card information, requires user checks before payments or messages, and uses encryption modeled on WhatsApp's system. Meta is seeking consumer revenue beyond advertising from its AI investment through subscriptions, possible shopping commissions and eventual smart-glasses integration, while expecting up to $145 billion in 2026 AI infrastructure capital expenditures. The launch came as broader markets weakened under pressure from higher oil prices and Treasury yields. West Texas Intermediate rose 3% above $96 a barrel amid escalating Middle East tensions and supply-disruption concerns, while the Treasury Department announced a $6 billion government-debt buyback, three times the normal amount. AI safety, energy use, public-service strain and data-center opposition have added uncertainty to the sector. Meta's debut also followed an agreement to pay up to $18 billion to settle claims by state attorneys general alleging that it misrepresented harms associated with Facebook and Instagram.
