Meta stock opened October 5, 2026 around $728 after a volatile early month pullback from its September surge of roughly 25-27 percent. The primary near-term catalyst is a Deutsche Bank ad-spend check released that morning showing digital advertising outperformance, with Meta receiving the strongest commentary and agencies lifting Q4 and Q1 forecasts; the shares responded with an immediate 2 percent-plus gain. Traders are also weighing ongoing momentum from the September launch of the Muse AI agent, which achieved rapid downloads and app-store leadership, alongside new AI-infused hardware such as updated Ray-Ban Meta glasses. Offsetting factors include elevated 2026 capex guidance of $130-145 billion and the upcoming October 28 Q3 earnings release, where ad-revenue trends and AI monetization progress will be closely scrutinized.
