According to alternative data provider TickerTrends, Meta AI agent Muse's daily net new users have plummeted by 62.4% from a September peak of approximately 198,000 to about 74,000. Morgan Stanley estimates that the monthly service cost per Muse user ranges from $3 to $130, with a baseline scenario of $37, significantly exceeding Meta's global average annual revenue per user of $70. Morgan Stanley anticipates that Muse's monetization will not occur until late 2027 to late 2028 at the earliest. Meta's current valuation expansion is built on a "billion-user scale" growth narrative, yet its daily active users are currently less than 3 million.
