Meta's recent stock momentum stems primarily from the early September launch of its Muse personal AI agent, which quickly topped app charts and validated heavy infrastructure spending, fueling a roughly 27% rally over the past month amid broader AI trade enthusiasm. Traders are also watching the late-October Q3 earnings release, where revenue guidance of $61-64 billion and updates on ad growth versus rising capex will likely set near-term direction. The new Meta Enterprise Platform announcement at month-end adds potential business revenue streams, though competition from OpenAI's agent offerings and sustained AI model development costs introduce uncertainty for any specific October close threshold.
