Meta's strong third-quarter results, including $64.6 billion in revenue that beat estimates and robust advertising growth, combined with upbeat fourth-quarter guidance of $73-76 billion, are lifting trader sentiment ahead of the October 22 close. The company highlighted progress with its Muse AI agent and frontier models while raising full-year capital expenditure guidance to $135-145 billion to fund data centers and chips amid competition with OpenAI and Anthropic. After-hours trading saw shares jump from a $697.52 close on October 21, reflecting optimism about AI monetization despite higher spending and a planned non-voting share class. Earnings momentum and AI velocity remain the key near-term catalysts.
