Been thinking about the whole PayPal vs American Express debate lately, and honestly the narrative around PYPL has shifted pretty dramatically over the past few years.

Like, remember when PayPal was supposed to be the unstoppable growth story? Their stock has tanked nearly 80% in five years. The core issue is pretty straightforward - their active account growth basically flatlined. They went from 426 million to 439 million between 2021 and 2025. That's... not great when you consider they originally targeted 750 million by now. They've been chasing growth through Venmo, branded checkout, BNPL services, all these side bets, but none of it has really moved the needle on their core problem.

Meanwhile they're cutting costs, doing aggressive buybacks just to prop up EPS numbers. For 2026 they're still expecting EPS to decline mid-single digits. So yeah, the stock might look cheap at 9x earnings, but there's probably a reason for that valuation.

Now here's where American Express gets interesting. Most people lump AXP in with Visa and Mastercard, but the business model is completely different. Visa and Mastercard just operate the network - they don't issue cards or carry the debt. American Express does both. They issue their own cards, they hold the balance sheet, they earn the interest. That's a massive structural advantage.

What I find compelling is their closed-loop system. They're not trying to be everything to everyone like PayPal. They're focused on affluent, lower-risk customers and that focus is actually their moat. The peer pressure in financial services often pushes companies to chase volume over quality, but American Express has resisted that. Their strategy of locking customers into their ecosystem is working - analysts expect 15% EPS CAGR through 2028. And they're trading at just 17x earnings for that growth trajectory.

Interest rates are another angle worth considering. If rates go up, AXP's net interest income rises. If rates fall, consumer spending picks up and they earn more on processing fees. That's genuine optionality that PayPal doesn't have.

So yeah, I'd probably lean toward American Express over PayPal at this point. One's a company fighting to stay relevant in a crowded market, the other's built a durable competitive advantage that keeps compounding. The valuation gap makes sense when you look at the underlying business dynamics.
