Meta's recent 25% September rally, fueled by the Muse AI agent launch and expanding partnerships for shopping and business use, underpins trader focus on the stock closing the week of October 5 near current levels around $728. Heavy 2026 capital expenditure guidance of $130–145 billion for AI infrastructure continues to pressure free cash flow despite 28% Q2 revenue growth, creating uncertainty ahead of late-October earnings. Volatility from late-September swings near $780 highs and competitive AI developments from peers add to the balanced probabilities across the $710–$750 range, with traders weighing sustained ad momentum against spending dilution risks.
