AI Economy
When AI agents need to pay each other for services, none of the existing payment infrastructure works.

The AI agent economy is projected to reach $182 billion by 2033, growing at nearly 50% annually. Agents are being deployed across sales, legal, healthcare, finance, and government. They are making purchasing decisions, filing documents, analyzing data, and increasingly transacting with other agents.
There is a problem nobody is talking about publicly. The payment infrastructure that agents need does not exist on traditional networks.
## The $0.30 wall
Visa and Mastercard both impose minimum transaction floors. The effective minimum for a processed card transaction is approximately $0.30 when fees are accounted for. For many agent-to-agent transactions the value is fractions of a cent. A $0.30 minimum makes those transactions economically impossible.
Blockchain networks were proposed as an alternative. But gas fees on Ethereum regularly exceed the value of small transactions. Layer 2 solutions reduce fees but introduce complexity and latency that real-time agent workflows cannot accommodate.
## What a purpose-built rail looks like
A payment rail built for AI agents needs three things: sub-cent minimum transactions, real-time settlement, and API-native access without human authentication at each step. Internal credit ledger systems satisfy all three requirements.
## The window is open
Every major payment company and cloud provider will eventually build this. The question is who builds the ecosystem first. Payment rails are winner-take-most markets. The network that agents are built on first becomes the default. The window for an independent AI agent payment rail is open right now. It will not stay open.
