Meta's Muse AI agent drives 25.8% stock surge in 16 days; US-only availability

Meta's new AI agent, Muse, has been linked to a 25.8% increase in Meta's share price over 16 days, though the causal link is inferred from market reaction. The chatbot is currently available only in the USA, limiting immediate global impact. This signals strong market enthusiasm for AI-driven consumer products, but sustainability and broader rollout remain uncertain.
