Business model and strategy
Block
How it makes money
Block runs a two-sided network. On the seller side, Square charges a fee on each card payment (in the U.S. on its free plan, 2.6% plus 15 cents in person and 3.3% plus 30 cents online) and adds paid software, hardware, payroll, banking and Square Loans. On the consumer side, basic Cash App transfers are free;
Growth strategy
Block's 2026 plan has four parts. Square is selling to larger and international sellers through a field sales team and independent sales organization partners; international GPV grew 28% in the second quarter of 2026. Cash App wants to be the main bank account for people with several income sources, using direct deposit and Cash App Green rewards status;
Competitive advantage
Block's advantage is owning both ends of many small transactions. Cash App's peer-to-peer network spreads by itself, since receiving money means downloading the app, and every added product (the Cash App Card, direct deposit, Borrow, Afterpay) raises revenue per customer without new acquisition cost.
Klarna
How it makes money
Klarna earns money on both sides of a purchase. Merchants pay Klarna a fee on each transaction because offering installments tends to lift conversion and basket size; Klarna pays the merchant upfront and carries the repayment risk (its published US standard rate for Pay in 4 has been 3.29% plus $0.30).
Growth strategy
Klarna calls itself an 'everyday finance network'. The strategy has three parts: distribution through large acquirers and platforms (J.P. Morgan Payments went live in August 2026), higher-frequency products such as the Klarna Card and paid Memberships (2 million subscribers in Q2 2026, eight times a year earlier), and higher-yield lending such as Fair Financing, which 256,000 merchants offered by Q2 2026.
Competitive advantage
Klarna's edge is scale and funding. It reaches more than 120 million active consumers and over 1.2 million merchants in 26 markets, and distribution deals with payment platforms such as J.P. Morgan Payments, Stripe and Adyen switch Klarna on for merchants without a new integration.
