What began as a race to build the smartest AI models is evolving into something much larger: machines that don’t just think and communicate — they spend.
- Circle is supplying USDC to OpenMind to enable autonomous payments between AI agents.
- The partnership reflects a larger industry trend: crypto is becoming the settlement layer for machine-to-machine transactions.
- The emerging x402 standard is gaining traction among OpenMind, Coinbase, AWS, Anthropic and NEAR.
- Agentic payments are early and experimental — but they are quickly attracting infrastructure providers and investment.
In the last three months, multiple technology companies have started experimenting with autonomous payments between AI agents, and stablecoins are becoming the preferred medium of exchange.
Circle’s latest move is part of that pattern. The company has agreed to supply USDC to OpenMind, a robotics and artificial intelligence startup developing systems where autonomous agents pay one another for data, services and compute time. To the outside world it looks like a corporate partnership. Inside the industry, it is viewed as a blueprint for a machine economy.
When AI Models Need To “Earn” and “Spend”
Autonomous agents operating across the internet can already scrape information, generate content, request API access and analyze data. Each action costs money. The next step is to give these agents the ability to pay for what they consume — not through human approval screens, but automatically.
For OpenMind, the logic is simple: if robots and software agents are going to handle tasks without human supervision, they must also handle the payments that keep those systems working. Instead of credit cards or banking rails, USDC micropayments will settle these interactions instantly at scale.
A Crypto Protocol Becomes an AI Standard
The broader industry has been searching for a transactional language for machine economics. Over the past few months, x402 — a crypto-native payment standard — has become the leading candidate.
OpenMind was among the first robotics firms to propose a concrete use case, and Coinbase began exploring the same protocol shortly afterward. AWS, Anthropic and NEAR later gravitated toward the emerging standard, forming a loose ecosystem of companies experimenting with autonomous payments.
Circle’s involvement now gives the movement a fully regulated dollar-pegged asset, which removes one of the biggest barriers to machine commerce: volatility.
Stablecoins Are Quietly Positioning Themselves for an AI World
USDC has been seeing rapid issuance — more than 77 billion tokens are now circulating across multiple blockchains, with several billion minted in the past week alone. Most recently, Solana has become the primary destination for fresh USDC supply, while Ethereum remains dominant for high-value settlement.
But Circle’s innovation isn’t only the token — it’s the infrastructure. The company’s Gateway project aims to make USDC transferable across blockchains without manual bridging, meaning AI agents won’t need to care whether a transaction happens on Solana, Ethereum or any other chain.
The long-term goal is to let machines choose the cheapest, fastest settlement route automatically.
The Missing Piece: Real-World Deployment
Agent-to-agent payments are still a frontier technology. No major AI company has deployed them at consumer scale, and OpenMind has not yet demonstrated live USDC usage in its robotics applications. That hasn’t stopped capital from flowing in: the startup secured an undisclosed seed round from Amber Group, followed by a $20M fundraise led by Pantera Capital. Pi Network is also among the investors.
Whether OpenMind delivers or not, the direction of the industry is now clear: AI won’t just talk to AI — it will pay AI.
