Meta's stock has surged roughly 36% in September on the rapid adoption of its Muse personal AI assistant, which topped app charts and validated heavy AI investments while easing concerns over returns on spending. The rally pushed shares near all-time highs around $780 and a $2 trillion market cap before a 3.3% pullback on September 25 left the price at $751.66 amid profit-taking. Trader consensus on the week-of-September-28 close reflects this momentum tempered by volatility, with strong bids on sub-$710 and $780–800 ranges highlighting uncertainty around sustained gains versus near-term consolidation. Key near-term influences include ongoing analyst upgrades citing Muse's monetization potential and Meta's Connect event features, though earnings are not due until late October and broader tech sentiment could sway the outcome.
