Meta Platforms Inc.’s (META) Muse topped Apple’s U.S. App Store on Sept. 18, 2026, signaling early consumer traction since its U.S. debut. The rise has prompted scrutiny over the extent of data access the AI agent requires, while rising AI capital expenditures may pressure free cash flow.
App Store Momentum
Muse launched in the United States on Sept. 8, 2026, for adults and is available on iOS, Android, the web, and WhatsApp. Meta markets Muse as a task-oriented personal AI agent that can book travel, shop, and integrate with popular services to send emails and messages.
Third-party tracking showed Muse climbed to No. 2 in the U.S. App Store within days of launch and recorded more than 83,000 initial iOS downloads. By Sept. 18, it reached No. 1 among free apps on Apple’s U.S. App Store, surpassing rivals such as ChatGPT.
Ad Growth and AI Costs
In Q2 FY2026, Meta reported total revenue rose 28.0% year over year to about $60.8 billion, with Family of Apps revenue also up 28.0% to approximately $60.4 billion. Family Daily Active People averaged 3.6 billion in June 2026, a 3.0% increase year over year, while ad impressions across the Family of Apps grew 14.0% in the quarter.
Commentary on the quarter highlighted heavy AI capital expenditures (CapEx) that are weighing on free cash flow, although strong operating cash flow supports these investments. These AI expenses reflect long-term infrastructure and product spending to advance agentic AI systems like Muse.
Trust and Data Concerns
Muse’s usefulness depends on access to extensive personal data, including emails, messages, calendars, and shopping details. Users may hesitate to grant such broad access, posing a risk to adoption and consent flows.
Technically, Muse runs on Meta’s Muse Spark AI model family, designed for agentic AI that pursues multi-step goals. The product connects with calendars, payments, email, and other apps through a controlled architecture that includes a “Sentinel” component to govern permissions and network access.
No formal regulatory investigations or enforcement actions related to Muse have been reported.
