In 2026, Affirm generated approximately $2.4 billion in annual revenue, proving that Buy Now, Pay Later (BNPL) isn’t just a checkout feature—it’s a full-scale financial infrastructure business built on data, risk modeling, and merchant economics.
Most founders think fintech growth comes from charging users. Affirm flips the model. Its success is driven by monetizing merchants, optimizing transaction flow, and using credit risk as a revenue lever rather than a cost center.
In this breakdown, you’ll learn how Affirm turns everyday purchases into recurring platform revenue, how its unit economics stay profitable at scale, and what entrepreneurs can replicate when building their own embedded finance platforms.

Final Thought
Affirm proves that fintech platforms don’t win by lending more—they win by embedding themselves into commerce itself. By becoming part of the checkout experience, it turns every purchase into a potential revenue event.
For founders, the real insight is that data and risk modeling are monetization tools, not just compliance requirements. The better you price risk, the more confidently you can scale revenue without sacrificing margins.
If you’re entering the embedded finance space, focus on trust, transparency, and merchant economics first. Do that well, and your platform won’t just process payments—it will become a financial backbone for entire industries.
