Meta bulls have a new Muse stat to love. Amazon could spoil it.

The meteoric rise of Meta's (META) new Muse AI agent looks to be continuing despite a few new stumbling blocks. Daily active users for Muse keep climbing, hitting 2.182 million on Oct. 5, according to new data from Similarweb. Usage has risen steadily throughout October. The increase may help soothe some concerns as Muse has reportedly hit a new hurdle: websites — Amazon (AMZN) being the top-of-mind example — blocking AI agents from browsing or completing purchases. If Muse's usefulness becomes limited as more websites treat AI agents as bots or security risks, that could dent the new bullish case for the stock that has developed since the agent's September launch.Muse continues to grow. Meta stock is down 7.
