SQ vs PYPL: Block vs PayPal — Two Fintechs Diverging
Block owns the merchant ecosystem (Square) and the consumer financial super-app (Cash App). PayPal owns legacy checkout and Venmo. Both have fallen hard from their 2021 peaks, but for different reasons. Block's problem is execution and Bitcoin distraction; PayPal's problem is structural — the checkout button it built its empire on is being commoditized by Big Tech.
Cash App's Financial Services Depth Is Block's Real Moat
Cash App started as a peer-to-peer payments app, but it's become something closer to a bank for underserved Americans. Direct deposit, a Visa debit card, fractional stock investing, Bitcoin buying, and a growing credit product — Cash App is a financial super-app for the demographic that doesn't have a traditional brokerage account. That's a different — and larger — market than PayPal's legacy checkout users.
Venmo has similar peer-to-peer scale but has been much slower to add financial services depth. PayPal has introduced Venmo credit cards and some investing features, but Cash App's revenue per active user is materially higher — and growing faster. That gap is what matters for long-term earnings.
Business Comparison
- Square: merchant POS + software + loans
- Cash App: peer-to-peer + financial services
- Bitcoin exposure (Dorsey personal focus)
- More volatile, founder-led company
- Two-sided ecosystem creates flywheel
- Legacy checkout button losing share
- Venmo: large user base, low monetization
- Braintree: developer payment gateway (strong)
- New CEO turnaround — Chriss
- Cheaper valuation, higher risk
Braintree Is PayPal's Underrated Asset
Most investors focus on PayPal checkout vs Apple Pay, but Braintree — the developer-facing payment gateway PayPal acquired in 2013 — is a real business. Braintree powers checkout for Uber, Airbnb, and hundreds of other major apps. Its developer adoption is strong and sticky. The challenge: Braintree takes payment volume but at lower margins than branded PayPal checkout.
As Braintree grows as a share of PayPal's overall revenue mix, margins come under pressure — PayPal earns less per transaction when it's operating invisibly via Braintree vs. when users click the branded PayPal button. This is a known structural pressure the new CEO needs to address through volume scale or margin improvement in Braintree's pricing.
