Meta's stock has traded near $728 following a sharp September rally fueled by the early success of its Muse personal AI agent, which quickly gained users and downloads after its September 8 launch and helped ease concerns over heavy AI infrastructure spending. Recent momentum stems from strong advertising revenue growth, AI-driven engagement tools on Instagram and other platforms, and the rollout of an enterprise AI platform led by a new executive hire. With Q3 results not due until late October, short-term trader sentiment reflects optimism around monetization potential alongside ongoing capex pressures that have weighed on free cash flow. Volatility remains elevated after the stock approached $780 highs before pulling back.
