Meta Platforms (META) shares declined approximately 3% during Monday's premarket session, marking a second consecutive day of weakness for the first time since August. Despite this short-term downturn, the stock has delivered an impressive 32% gain in September, driven largely by the rapid adoption of its new standalone AI personal assistant, Muse. The recent price drop coincides with broader turbulence in the artificial intelligence sector following OpenAI's decision to temporarily halt training on new models. Analysts suggest that investor sentiment is shifting toward competitive dynamics, specifically monitoring expected rollouts of rival consumer AI assistants from major platforms like Google and OpenAI, which creates headwinds for Meta's stock trajectory. Wall Street maintains a predominantly positive stance regarding Meta's long-term prospects despite the recent volatility. Analyst targets range widely from $580 to $950, reflecting divergent views on Muse's revenue potential and future competition. While some firms like Jefferies highlight Muse as an unexpectedly successful product launch with accelerating adoption, others express reservations about its monetization path and upcoming operational spending. Muse generates income primarily through modest transaction-based charges, though the long-term revenue model remains unclear to investors. The application has accumulated 2.5 million downloads in its initial fortnight and is being used for sophisticated tasks like parking violation payments. Meta's shares currently trade at $751.66, sitting just 1% beneath their 52-week peak of $779.82.
