The bare knuckles fight for the checkout button

Today, I’m digging into PayPal.

It’s one of the original internet success stories but it plays in what is now one of the most competitive industries on earth.

Here’s the quick overview (as if you need it):

• The business: PayPal earns money by taking a small cut of transactions and layering on extras like instant transfers and credit.

• The size: About $33B in trailing revenue and $5B in profit, with roughly 47% gross margins.

• The model: A two-sided network. Consumers on one side, merchants on the other. This kind of marketplace thrive when trust and adoption are high.

• Their edge: Brand recognition, a massive merchant footprint, and years of risk data and processes that keep fraud losses low.

• The catch: Growth has slowed, and competition is fierce.

Before we take a look at competition, I've always been a little confuse on which party actually pays fees to Paypal (and their competitors). Let's take a look:

For business transactions, the receiver (merchant) pays PayPal’s transaction fee, usually around 2.9% plus a small fixed charge. For personal transfers, payments funded by a bank or PayPal balance are free, but if funded by a credit or debit card, the sender pays the fee. Cross-border and instant transfers also carry extra charges paid by the sender or receiver. In short, business users fund most of PayPal’s revenue, while most personal payments stay free unless convenience or credit cards are involved.

Now, let's take a look at their competition.

The competitive reality

This space is brutally crowded:

• Apple Pay and Google Pay are winning on convenience and phone integration.

• Shop Pay (Shopify) and Amazon Pay dominate native checkout experiences.

• Stripe and Adyen are scaling fast on the merchant-processing side.

• Affirm, Klarna, and other Buy Now, Pay Later players chip away at PayPal’s installment credit product.
  Even banks and card networks have built their own instant-pay options.

That’s the challenge: PayPal has a strong brand, but its margins face constant pressure as competitors bundle payments into their ecosystems and undercut on fees.

This profile is a bit of a tough one for me to write because the business is just so unlike anything that I would ever build myself.

I think the main takeaway from PayPal for most of us should be that two-sided marketplaces are incredibly difficult to build. If you're thinking about building a two-sided marketplace, I wish you luck. You're going to need it!

With that said, I love their Venmo product. And if they end up being integrated deeply with ChatGPT, maybe they will end up leaving the their competitive sharks for clearer water.

This is one I'll be following regularly!

With that, I'll see you tomorrow.
