Meta stock surges after Muse AI app launch
6.9 Markets Meta stock surged up to 25% in September 2026 after the Muse AI app launch, which topped the US App Store and boosted investor confidence in Meta’s AI direction.
Meta Platforms saw a remarkable stock rally in September 2026, with shares climbing between 7% and 25%, marking the company’s strongest monthly performance in over two years. This surge was largely attributed to the launch of the Muse AI assistant app on September 8, which quickly became the most-downloaded free app in the US Apple App Store, overtaking ChatGPT. Muse offers both free and paid tiers, enabling users to autonomously complete multistep tasks such as booking travel, sending emails, shopping online, and integrating with third-party services. The app’s rapid adoption shifted investor sentiment, leading to analyst upgrades—most notably, Wells Fargo raised its price target for Meta from $640 to $796. The rally occurred despite temporary service disruptions on Facebook and Instagram. Investors are now looking forward to further AI and device announcements at the upcoming Meta Connect event, with Muse’s success seen as a pivotal moment in Meta’s AI strategy.
