Recent momentum in Meta shares stems primarily from the September 8 launch of Muse, its standalone personal AI agent powered by the Muse Spark model family, which quickly reached top-three U.S. app-store rankings and demonstrated strong early usage. JPMorgan’s September 10 upgrade to Overweight with an $820 price target, alongside other bullish notes highlighting multi-year AI monetization beyond advertising, reinforced trader optimism. A new quarterly dividend declaration added modest support. The stock traded near $644–$650 amid broader AI-sector rotation, with next-quarter earnings due October 28 serving as a key upcoming catalyst. Heavy infrastructure spending and any last-minute regulatory or competitive updates remain potential swing factors for the September 11 close.
