Stablecoins' Real‑World Adoption Pathways

Welcome back to the Fintech Takes podcast. I’m Alex Johnson, joined by Marc Rubinstein, author of the fantastic Net Interest newsletter. 

In this episode, we bounce through some of Marc’s most insightful writing from the past year (linked below) to spotlight the structural forces shaping 2026.

We explore why the U.S. has thousands of community banks, the idiosyncrasies of our 30-year mortgage product, the growing industry focus on agentic commerce, and why stablecoin infrastructure is coalescing around large, permissioned systems — and what all of that reveals about regulatory incentives, institutional power, and the future of financial infrastructure.

Highlights include:

• Why the U.S. has thousands more banks than any other developed market

• How agentic commerce is being driven more by investor decks than consumer behavior

• Why OpenAI might accidentally save small merchants

• Why stablecoins are moving onto permissioned, institution-backed rails (and will be increasingly shaped by players like Stripe).
