X filled with posts praising Muse over the weekend

Meta and Shopify said Monday that they are teaming up to allow Meta’s consumer-focused AI agent Muse to complete purchases on behalf of users, The Wall Street Journal reported.

Over the weekend, the platform X was filled with posts by users praising their new Muse agents, the Journal reported. Just two weeks after Meta released the agent, the app to access it had reached No. 1 on Apple’s App Store. Shares in Meta jumped 11% on Monday — its biggest one-day gain since April 2025 and its highest close since October, the Journal reported.

The excitement around Muse is one of the first indications that AI agents could catch on with everyday users, the Journal reported. Until now, AI agents have largely been the stuff of enterprise technology — heralded as the new interface for business software and touted as working alongside human employees. Companies are already using agents to provide customer service, write code and analyze data, the Journal reported.

FedEx is planning an AI agent workforce to work with its human staff, Chief Digital and Information Officer Vishal Talwar told the Journal earlier this year. In the next two years, the average global Fortune 500 enterprise will run over 150,000 AI agents, according to market research and IT consulting firm Gartner, the Journal reported.

But there have been plenty of challenges for enterprises in rolling out and managing AI agents — among them cost, cybersecurity risks and the potential for too many agents, the Journal reported.

For consumers, too, the challenges around AI agents abound, the Journal reported. Agents within Muse can book doctor’s appointments, buy products, manage finances, send emails and do any number of other things on users’ behalf. For Muse to work, it needs access to users’ data — their emails, calendars, e-commerce sites and bank accounts — and that is one area where Meta’s strategy seems destined to face hurdles, the Journal reported.

The stakes with a personal agent are elevated because agents are empowered to buy products, set appointments and book travel by themselves — all of which could cost users money if the agent errs, the Journal reported. The risk of the rogue AI agent is where tech providers will need to provide assurances to both enterprises and consumers. And while many companies have teams to help govern and protect against AI agent mistakes, consumers don’t, the Journal reported.
