Meta Shares Jump 6.7% After Muse AI Agent Launch

Meta Platforms saw its stock rise 6.7% in afternoon trading following the launch of Muse, a new artificial intelligence agent built to handle everyday consumer tasks. The software integrates directly with Meta's social platforms and external services to send emails, book reservations, and manage purchases.

The service features a free tier as well as paid subscriptions priced at $20 and $100. Mizuho analyst Lloyd Walmsley stated that the rollout is a meaningful step toward generating tangible financial returns from the company's large AI capital expenditures.

The release follows a 3.5% gain six days earlier, when Meta opened paid developer access to its Muse Spark 1.3 model. Co-founder and CEO Mark Zuckerberg described that model on X as the company's biggest jump yet in coding and agentic tasks, while Chief AI Officer Alexandr Wang told Axios it paves the way for 24/7 personal agents. Broader market sentiment also improved after CNBC reported that Federal Reserve Governor Christopher Waller signaled support for holding interest rates steady, which lowered Treasury yields.

Meta shares have experienced 14 swings greater than 5% over the past year. The stock is flat year to date. At $655.03, the stock trades 16% below its 52-week high of $780.25 set in September 2025. A $1,000 investment in Meta five years ago is now worth $1,733.
