Meta’s stock has surged on the rapid adoption of its Muse AI agent, which topped app charts with millions of downloads and prompted multiple analyst price target hikes to as high as $920, validating heavy AI infrastructure spending and lifting shares toward $2 trillion market value. The recent 36% September rally through late last week, followed by a 3.3% pullback to close near $752 on September 25, leaves the precise week-of-September-28 closing range highly contested. No major earnings or regulatory catalysts are scheduled before October, so trader consensus reflects ongoing momentum from AI product traction tempered by typical post-rally volatility and broader market sentiment.
