Meta shares surged during the week of September 21, 2026, climbing from a prior close near $666 to intraday highs above $780 and a September 24 close of $777.59, driven by rapid adoption of the new Muse AI agent, which topped app-store charts with hundreds of thousands of daily downloads. Multiple analysts raised price targets sharply—to as high as $995—citing potential new revenue streams from freemium AI subscriptions that could add tens of billions annually with contained costs. This followed Q2 results showing 28% revenue growth to $60.8 billion but an EPS miss tied to elevated AI infrastructure spending, with full-year capex guidance narrowed to $130–145 billion. Strong ad pricing and impressions continued to support the core business ahead of the October 28 Q3 earnings release.
