Mark Zuckerberg Says Muse Ordered Him a Watermelon

Mark Zuckerberg had Muse do his grocery shopping. The Meta CEO posted a photo to X on Monday morning of a whole watermelon sitting on his kitchen counter, with the caption: “Muse ordered me 🍉 how thoughtful!”

The photo shows a round, striped watermelon on a wooden kitchen table, with a brown paper shopping bag from Safeway visible in the background. Zuckerberg did not say which store or delivery service Muse used to place the order.

Meta’s chief AI officer Alexandr Wang appeared to riff on the post Monday morning too, posting simply: “vibes kinda good 🍉”

Shopping is Muse’s most contested feature

Muse, Meta’s personal AI agent launched Sept. 8, can shop, book, and run errands across connected accounts with the user’s approval. Shopping has been one of its headline capabilities and its most contested: Amazon blocked Muse from completing purchases on Amazon.com on Sept. 20, saying the agent did not identify itself and accessed customer account pages without authorization. Meta, meanwhile, has been signing retail partners that welcome agent-driven shopping, including Best Buy, Gap, Sephora, Walmart, and Wayfair.

The tracking account @Musecases, which documents everyday uses of Muse, quote-posted Zuckerberg’s photo: “Zuckerberg turned a fruit into a launch event.”

Why it matters

The post is a public vote of confidence from Meta’s own CEO in the agent-commerce push the company is making. At a moment when retailers are split over whether AI agents get to shop freely, with Amazon blocking Muse while Walmart and other retailers partner with it, Zuckerberg is showing that he trusts Muse with a real purchase of his own.

The post announces no new product details. But it puts a human face on Meta’s bet that shopping through an agent becomes routine, and it raises the bar for every executive who has told their customers that agents are ready to handle their money.
