Meta's stock closed the Oct 12 session near $743 after surging on the launch of its Muse Wonder frontier large language models and strong early metrics for the standalone Muse AI agent, including 73% day-one retention and rapid downloads. Traders view these developments as evidence Meta has narrowed the gap with OpenAI and Anthropic in agentic capabilities, supporting competitive positioning ahead of the late-October earnings release. Elevated 2026 capital expenditure guidance between $130-145 billion and ongoing infrastructure buildout remain key variables that could pressure free cash flow or spark volatility, while the closely matched probability distribution around the $720-760 ranges reflects uncertainty over whether AI momentum will sustain gains or yield to macroeconomic or spending concerns through week's end.
