Meta's Q3 2026 results highlighted AI-driven gains in its core advertising business, with revenue rising 26% to $64.6 billion as ad impressions grew 10% and average price per ad climbed 14%, fueled by improved targeting algorithms and performance. Traders are weighing this momentum against a $9.9 billion legal charge that pressured margins, alongside aggressive AI infrastructure spending and a $25 billion equity raise to fund models like Muse Wonder and Muse Ember for agentic tasks. Recent leadership shifts in infrastructure and ongoing rollout of Muse AI agents add uncertainty, while the stock hovers near $635 amid broader tech volatility. No major catalysts are imminent beyond continued AI updates and Q4 guidance execution.
