Circle launches Arc as an economic operating system for AI agents

Circle says it has launched Arc, a global economic operating system built over two and a half years. The platform supports applications and services spanning social trading, DeFi, payments and capital markets, and is designed so AI agents can use it for transactions, contracts and coordination.

Circle describes Arc as infrastructure for making agent activity more trusted and verifiable. Its Arc Agent Sector can provide cryptographic proofs of an agent’s identity, work and data use, addressing what Circle calls the black-box risk of AI systems. The discussion does not establish how broadly these verification mechanisms will be adopted.
