Meta shares opened near $750 on September 28 but traded sharply lower, falling more than 5% intraday to the $714–$722 range amid profit-taking after a 36% September rally fueled by the popular Muse AI agent launch. The immediate catalyst was Meta’s announcement of a new Meta Enterprise Platform division and the hiring of MongoDB’s CEO to lead enterprise AI sales, including productivity tools built around Muse. Traders appear to be locking in gains following weeks of analyst upgrades and strong download momentum for the consumer AI agent, while broader Nasdaq weakness added pressure. With next earnings due October 28 and no major regulatory or product deadlines today, the close will hinge on whether late-session buying stabilizes the price after the rapid run-up.
