Meta’s newly launched personal AI agent app Muse has driven overwhelming trader consensus toward an 84.5% implied probability it holds the top free spot on the US Apple App Store today. Released around September 8 with task-oriented capabilities beyond chatbots—such as handling research, bookings, purchases, and integrations with email, calendars, and services like Spotify—the app climbed rapidly from initial mid-chart positions to #1 within a week. This surge reflects strong early user adoption of agentic AI features, Meta’s distribution advantages, and a free tier that boosted downloads ahead of competitors like ChatGPT. Other apps remain at lower or uncertain odds given the confirmed ranking shift, with minimal time left for last-minute changes before resolution.
