Just been digging into the BNPL space and honestly, there's something worth paying attention to here. About 90 million Americans are now using buy now, pay later services instead of credit cards, and that number keeps growing. Younger folks especially are making the shift.

Affirm is probably the most interesting BNPL stock to watch right now. They went public back in 2021 and have been steadily building out their ecosystem. What caught my eye is how they're different from traditional credit cards - their Pay in 4 loans are interest-free with payments spread over 6-8 weeks, versus credit cards that compound interest on unpaid balances. That's actually a meaningful advantage for consumers.

The growth metrics are solid. Their gross merchandise volume jumped from $20.2 billion back in 2023 to $36.7 billion last year - that's a 38% surge. No-interest loans alone grew 74% in their latest quarter. They've locked in partnerships with Amazon and Shopify, which gives them serious distribution. Digital wallet integration added another 70% boost to partner volume.

What's interesting about the broader BNPL stocks landscape is that even if Trump's proposed credit card rate cap doesn't happen (which most analysts think is unlikely anyway), there's still a structural shift happening. Banks are tightening lending to riskier borrowers, which creates more room for BNPL providers to capture that demand.

On the profitability side, Affirm actually turned a corner. They went from a $1.2 billion operating loss in 2023 down to $87 million last year, and just posted their first profitable quarter on a GAAP basis. They're projecting $47.5 billion in GMV for 2026 with 7.5% operating margins.

If you're looking at BNPL stocks as a potential position, Affirm's the one that seems to have figured out the unit economics. The partnerships are real, the adoption curve is there, and they're actually making money now. That's more than you can say about a lot of fintech plays.
