Meta’s stock has rallied sharply in September on strong adoption of its Muse personal AI assistant and related product updates unveiled at Connect 2026, including expanded agent features, smart-glasses integrations, and retailer partnerships that position the company as a consumer AI contender. This momentum follows Q2 results showing 28% revenue growth to $60.8 billion, though EPS missed estimates amid legal charges and elevated AI infrastructure spending projected at $130–145 billion for the year. Recent profit-taking and competitive concerns have triggered a pullback from near-record levels around $750, leaving the share price near $715 as traders assess whether Muse monetization and upcoming models like Watermelon can sustain the rerating into quarter-end.
