The Coinbase CEO Brian Armstrong has been publicly championing what he calls “agentic finance,” or “AiFi”, a framework where autonomous AI systems manage crypto wallets, execute transactions, and participate in commerce without human intervention, arguing that crypto and AI are interconnected, not competing technologies.
The numbers backing the argument are getting hard to ignore. Coinbase’s x402 payment protocol, which launched in May 2025, has already surpassed 100 million machine-to-machine transactions in roughly nine months.
Armstrong’s claim that x402, Base, and USDC “power the vast majority of all agentic payments” is broadly supported by the ecosystem’s own numbers, with the combination reportedly facilitating the majority of agentic payments as of mid-2026. Notably, Coinbase no longer fully controls the standard it created.
The protocol has since been donated to a neutral foundation and now sits under Linux Foundation governance, backed by Google, Visa, Mastercard, Stripe, AWS, and Circle. That breadth of backing is the strongest evidence for Armstrong’s thesis, and, as we’ll see, also its biggest complication.
It is a sweeping vision, and it is not Armstrong’s alone. Crypto executives including Armstrong and CZ have leaned into the agentic-payments narrative, and McKinsey has estimated that AI agents could mediate $3 trillion to $5 trillion of global consumer commerce by 2030.
Whether AiFi becomes the next foundational layer of finance or the next well-marketed acronym will be decided not by a Jerry Maguire style mid-night manifesto, but by whether agents ever start spending real money at scale, and whether, when they do, it flows through Coinbase’s rails or someone else’s.
“If you’re in crypto, pivot to AI.”
I used to hear versions of this, and it’s the wrong way to think about the world. It’s zero sum, scarcity thinking.
Crypto is a general purpose technology. It’s infrastructure, the same way electricity or the internet is infrastructure. It…
