Meta’s Muse AI agent quickly gained market attention just two weeks after launch, signaling positive momentum for AI agents transitioning from tech demonstrations to mainstream products. Muse, officially launched by Meta earlier this month, is positioned as a personal AI agent capable of executing multi-step tasks and connecting to services such as email, calendar, payments, dining, and shopping. Currently, Muse has replaced ChatGPT as the most popular free app on the US iOS platform. According to analytics firm Sensor Tower, since its release on September 8, Muse achieved 730 thousand downloads in about five days and topped the App Store rankings.
Meanwhile, market expectations for diplomatic progress in the Middle East war pushed oil prices lower, further boosting market risk appetite. Reportedly, Trump indicated willingness to meet with Iranian President Pezeshkian, who is expected to attend the United Nations General Assembly in New York this week. In addition, there are reports that Iran has conveyed conditions for restarting negotiations to mediators.
