Muse AI Rally Puts Meta in Focus, Boosting Market Cap and Zuckerberg's Wealth

Meta Platforms' shares jumped about 11.4% to around $741.25 after Muse, its new AI assistant, sparked investor enthusiasm, adding roughly $192 billion to Meta's market value and more than $13 billion to CEO Mark Zuckerberg's net worth. Muse showed strong early traction with about 2.8 million downloads in 12 days (and a US daily record of 264,000), signaling potential monetization via advertising, subscriptions, and enterprise use as Meta eyes a broader AI-driven growth engine.
