The Future of Money: AI Economics Explained

Sean Neville, co-founder and CEO of Catena Labs (and co-founder of Circle), joins the show to explore the rise of AI economics and what it means for the future of payments, trust, and financial systems. From stable coins powering machine-to-machine transactions to identity layers for AI actors, Sean unpacks the building blocks that could reshape how value flows online. This episode is for anyone curious about the intersection of AI, crypto, and the next era of digital finance.

Key Takeaways

• AI actors are evolving into full economic participants, capable of executing payments and workflows.

• Stablecoins provide a more efficient and borderless payment rail compared to legacy systems, especially for AI-driven transactions.

• The biggest hurdle isn’t technology—it’s trust, identity, and accountability in agent-to-agent interactions.

• B2B use cases are likely to adopt AI-powered payments faster than consumer markets due to inefficiencies in existing flows.

• AI to human payouts and human to AI pay-ins will likely arrive before true AI-to-AI payment systems go mainstream.
