On September 8, Meta shipped Muse, its personal AI agent.
It runs in its own virtual machine. It connects to your email, your calendar, and your smart home. It keeps working after you close the app, and it’s available on the web, in the Muse app, and inside WhatsApp.
It can also buy things across the internet while you’re doing something else.
Meta isn’t first. OpenAI has been building checkout into ChatGPT, Perplexity has been selling agentic shopping for two years, and every large platform now has a version of this on its roadmap. What Meta changed was the scale. Meta has 3 billion users across its family of apps, and they’re getting an agent with a wallet.
My first thought was Visa and Mastercard and how they’ll benefit.
An agent that buys things needs a way to pay. Every payment needs a credential. Two companies run the rails most of those credentials settle on, and both earn a fee on every transaction that crosses them, plus a second fee for the services wrapped around it. Agentic order flow is order flow moving across Visa and Mastercard.
It’s first-level thinking.
And it’s correct.
But the closer I looked, the less it was worth to Visa and Mastercard.
The Substitution Problem
Bain estimates US agentic commerce reaches $300–500 billion by 2030, or 15%–25% of online retail. Morgan Stanley’s range is $190–385 billion. McKinsey’s is $3–5 trillion globally.
Where is this money coming from?
