Meta’s stock is enjoying its best month in more than two years thanks to the company’s hot new AI assistant

Meta Platforms is on track for its strongest monthly stock performance in over two years, a rally tied to investor enthusiasm for Muse, the company's new AI assistant. The product's growing popularity is being read by the market as early evidence that Meta's substantial artificial intelligence investments are beginning to translate into consumer-facing results.

The development matters because Meta has spent heavily on AI infrastructure, including data centers and computing capacity, without a clear near-term revenue story attached. A well-received assistant helps bridge that gap: it gives investors a tangible product to point to and suggests the spending may support engagement across Meta's existing apps rather than remaining a pure cost center.

What to watch from here is whether Muse's adoption holds up beyond its initial launch buzz, and whether Meta discloses metrics that let analysts separate genuine usage from novelty. Also worth monitoring is how advertisers and developers respond — sustained momentum likely depends on the assistant deepening time spent on Meta's platforms, not just generating headlines.
