Meta’s current ~$1.81 trillion market cap reflects strong recent momentum from the September launch of its Muse AI assistant and related models like Muse Wonder, which drove a 36% September rally and app-store dominance through demonstrated agentic capabilities and developer partnerships. Traders see the $1.75–2T band as most probable by late November because sustained advertising revenue growth and AI feature adoption continue to support valuation, even as heavy 2026 capex guidance of $130–145 billion pressures margins and free cash flow. Upcoming Q3 earnings on October 21 and any further model releases or monetization updates represent the main near-term catalysts that could shift consensus within the contested lower and higher ranges.
