Meta stock surges on Muse AI momentum

Meta shares rally on Muse AI launch

Meta Platforms’ (META) stock surged about 11% on September 21, 2026, trading around $741.24 as investors responded to early signals from its new Muse AI assistant. The move added momentum to a strong month for the shares and reflected growing expectations that Muse could become a meaningful contributor to Meta’s (META) growth.

The one‑day jump came shortly after a wave of analyst reports highlighted both rapid early user uptake and potential monetization opportunities from the assistant. With the stock still trading below several newly revised price targets, markets appeared to be recalibrating expectations for Meta’s long‑term earnings power tied to AI.

Muse AI product and pricing

Meta launched Muse on September 8, 2026, positioning it as a general‑purpose AI assistant integrated into its ecosystem. The service offers a basic version at no cost, alongside paid tiers priced at $20 and $100 per month aimed at heavier or professional users.

This tiered structure gives Meta scope to scale usage through a free entry point while layering subscription revenue for users needing higher volumes or enhanced capabilities. The presence of a $100 per month option underscores expectations that at least a subset of users may be willing to pay for more intensive access.

Early adoption metrics

Third‑party app‑intelligence estimates point to rapid early interest in Muse. In the first 12 days after launch, the assistant recorded about 1.8 million iOS downloads in the U.S. and Canada and roughly 2.8 million global installs over the same period.

Within that launch window, Muse reached an estimated 642,000 daily active users in the United States, suggesting not only strong download momentum but also active engagement. These figures have helped underpin analyst models that assume substantial future scale for the product.

Analyst upgrades and revenue scenarios

Wall Street has moved quickly to update models and price targets in light of Muse’s early data. Jefferies (JEF) outlined a scenario in which Muse could reach 1 billion users by the end of 2027, with 3% of them converting to paid subscriptions, implying about $10.8 billion in annualized revenue from the product.

In conjunction with that scenario, Jefferies (JEF) raised its price target on Meta to $875. Wells Fargo (WFC) lifted its own target to $796, and overall coverage has turned broadly positive, with 57 of 64 brokerages rating the stock at “buy” or higher and a median price target near $760, above the latest trading level.

Platform friction and security concerns

Despite the enthusiasm, Muse faces immediate operational challenges. On September 20, 2026, Amazon (AMZN) began blocking the assistant from automating purchases on its platform, citing concerns over unauthorized agent access, while Meta disputed how its handling of user credentials was characterized.

Separately, early reviews and technical analyses have raised privacy and security questions. Commentators noted that Muse encourages linking sensitive accounts and is opted in by default to use user data for training unless settings are changed. A disclosed macOS zero‑day vulnerability also raised concerns that an attacker could potentially misuse the assistant’s elevated privileges.

These issues highlight regulatory, trust and platform‑access risks that could affect how quickly Muse can scale into the ambitious revenue scenarios modeled by analysts, even as its launch has already reshaped market expectations for Meta’s AI strategy.
