Meta's strong September performance, fueled by the early September launch of its Muse personal AI agent—which quickly achieved millions of downloads and topped ChatGPT on iOS—has lifted trader sentiment around the stock's trajectory into October. The company's Connect 2026 event highlighted integrations with AI glasses and expanded enterprise offerings, reinforcing competitive positioning in large language models and agentic AI amid rivals like OpenAI. Recent volatility, including a late-September pullback after hitting 52-week highs near $780, reflects concerns over AI infrastructure spending and monetization timelines, even as analysts maintain a strong buy consensus with targets above current levels. Earnings on October 28 will provide the next major catalyst for assessing revenue growth from advertising and new AI features.
