Is Meta Platforms Stock a Buy as Revenue Continues to Soar?

META posted Q3 2026 revenue of $64.6 billion, up 26% and ahead of consensus estimates, with advertising revenue also climbing 26%. The print points to AI-driven ad performance carrying the top line.

The new Muse AI agents drew more than 10 million users across the U.S. and Canada within six weeks of launch. That adoption pace opens what the source frames as a fresh revenue stream beyond ads, though no monetization figures accompany the user count.

The bearish counterweight is spending. META is guiding capital expenditures of $135 billion to $145 billion on AI infrastructure. That scale of outlay raises the bar for returns, and the market will want proof that the ad momentum and Muse adoption justify it.

Valuation is the bull case's anchor. At a forward P/E of 19, the stock is described as attractively priced heading into 2027. Interpretation: a 19x multiple against 26% revenue growth implies the market is already discounting some risk from the capex load, which leaves room for upside if growth holds.
