One underappreciated AI trade might be payments.

Today, humans click "buy."

Tomorrow, AI agents may discover the product, compare prices, negotiate, purchase data/compute/services, and settle the transaction themselves.

That creates a completely different payment problem.

Card rails weren't built for autonomous AI agents.

AI agents need payments that are:
- instant
- programmable
- global
- available 24/7
- cheap enough for millions of tiny transactions

That's where stablecoins start to make a lot of sense.

Circle is already building wallets and payment infrastructure specifically for autonomous AI agents, including USDC nanopayments.

And traditional card economics can still involve 1-3%+ interchange depending on the transaction, before other processing costs.

Maybe the biggest stablecoin use case isn't humans paying with crypto.

Maybe it's machines paying machines.
