Meta Stock Jumps 4% as Muse Spark 1.3 Promises Ad Efficiency Boost

Meta's stock price surged by 4% after the release of Muse Spark 1.3, an AI model designed for coding and agentic tasks.

The new model is claimed to handle longer-horizon tasks better, manage multiple workflows in one thread, and improve coding efficiency.

Bank of America analyst Justin Post remains bullish on Meta's prospects, with a Buy rating and a price target of $810, implying about 32% upside from its September 3 close of $610.68.

The bank's case is based on the gap between Meta's execution and valuation, as well as the potential for improved ad efficiency and lower inference costs through MTIA custom-chip deployments.
