- Meta (META) stock rallied 6.06% on Wednesday, September 9, 2026, gaining $37.17 to reach $650.65 after the company debuted Muse, its standalone consumer AI assistant.
- Mizuho Securities analysts wrote that Muse "marks the beginning of a substantial product cycle for Meta that is not priced into shares," reiterating an Outperform rating with a $750 price target.
- KeyBanc Capital Markets held an Overweight rating with a $780 price target, saying it "continue[s] to believe the market underestimates Meta's AI positioning and product cycle."
- Mark Zuckerberg centered the launch pitch on privacy, unveiling a Secure Credential Store that prevents Muse from reading passwords or credit cards, plus user confirmation before sensitive actions like payments.
- Meta built Muse to function like messaging another person, available through the Muse app or directly within WhatsApp, with encryption modeled on WhatsApp so even Meta cannot read user messages.
- Meta shares remain down roughly 1% year-to-date, having recovered most of their earlier-2026 declines before Wednesday's rally.
Why it matters: Mizuho's $750 and KeyBanc's $780 price targets sit roughly 15–20% above the post-rally price near $650, meaning two major sell-side firms are explicitly betting Meta's AI push is underpriced. Zuckerberg is leading with encryption and credential isolation rather than raw capability, signaling where Meta sees its competitive edge.
