Meta Unleashes a New AI Weapon. Wall Street Sees Huge Upside for META Stock

Meta Platforms (META) is making another push to prove it can compete at the front of the artificial intelligence (AI) race.

On Sept. 2, Meta released Muse Spark 1.3, an updated model focused on coding and agentic workflows. The timing matters. Investors have been questioning whether Meta's enormous AI spending will translate into real business gains.

Muse Spark 1.3 is designed to handle longer tasks, use tools, manage several workflows, and correct its own plans. That moves Meta closer to the kind of AI agents that can work with limited human supervision. Meta says the model also delivers better performance in real-world coding use cases.

That could become important for Meta's broader AI strategy. The company is not simply trying to build another chatbot. It wants AI to sit inside Facebook, Instagram, and WhatsApp while also opening new opportunities beyond its core advertising business.

Meta Platforms Stock Has Had a Rough 2026

Meta Platforms stock is still down about 18% over the past year. Shares are also down roughly 6% year-to-date (YTD) while other "Magnificent Seven" members have gained by double digits. The biggest issue has been spending. Meta's second-quarter capital expenditures reached $31.08 billion, while free cash flow dropped sharply.

Investors are worried that AI infrastructure costs may rise faster than profits. At the same time, advertising remains strong and recent AI momentum has helped sentiment. The Muse Spark launch also gave shares another lift as META stock climbed more than 2% on Sept 2.

In terms of valuation, Meta does not look especially expensive compared with major technology businesses. Its trailing price-to-earnings (P/E) ratio is around 20.8 times, which is below the information technology sector median near 33 times.

That suggests investors are not paying an extreme premium despite Meta's AI ambitions. But the catch is clear. Earnings growth must eventually catch up with the spending spree.

Muse Spark Could Strengthen Meta's AI Case

The biggest opportunity from Muse Spark 1.3 is not the model itself. It is what Meta can build on top of it.
