Meta Platforms Stock Rose 25% in September. Is It Still a Buy in October?

META jumped 25% in September after launching Meta Muse, an AI agent built for everyday consumer use with a freemium subscription model. The product gives the market something it had been missing: a visible path to monetizing Meta's heavy AI infrastructure spending, which had been a core investor concern.

The rally has changed the valuation picture. META has moved from undervalued territory into a normal valuation range, according to the source analysis. That matters for positioning: the cheap-stock argument that drove earlier buying has largely played out after a 25% monthly gain.

Analysts expect modest October performance for META. The next major catalyst is Q3 earnings, and the stock appears to be waiting on those results before making its next big move. Long-term prospects look brighter if Muse gains widespread adoption, though that outcome remains unproven.

Interpretation: a 25% monthly run followed by a "normal valuation" label suggests the easy re-rating is behind the stock. From here, upside likely depends on evidence that Muse converts users into paying subscribers rather than on further multiple expansion.
