Affirm Holdings, Inc. and Klarna Group plc pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Affirm Holdings, Inc. and Klarna Group plc.

Affirm Holdings, Inc. business model: Affirm earns merchant-network revenue when consumers use its payment options, interest income on interest-bearing loans, card-network revenue, gains when it sells loans to third parties, and servicing income. Some plans carry 0% APR, while interest-bearing loans disclose a fixed repayment schedule. Affirm says it does not charge late or hidden fees.

Klarna Group plc business model: 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). Consumers pay interest on longer-term Fair Financing loans, late fees in some markets, and subscription fees for Klarna Memberships. The Klarna Card adds interchange income on everyday spend, and the Klarna app sells advertising and affiliate placements to merchants. Funding comes mostly from consumer deposits at Klarna Bank AB, which management said made up about 90% of funding in Q2 2026. Management tracks transaction margin dollars (revenue minus processing, credit-loss and funding costs), which reached $446 million, or 42.8% of revenue, in Q2 2026.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Affirm Holdings, Inc. stack up against those of Klarna Group plc.

Affirm Holdings, Inc. competitive advantage: Affirm underwrites each transaction individually in real time and offers fixed payment schedules without late fees. Its distribution includes integrations with major commerce platforms and merchants, while its funding model uses warehouse facilities, securitizations, and loan-sale partnerships.

Klarna Group plc 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. Because Klarna Bank AB is a licensed Swedish bank, roughly 90% of its funding comes from consumer deposits rather than wholesale credit, a cost advantage over non-bank lenders like Affirm. Short-duration Pay in 4 loans also let it reprice risk quickly; provisions were 0.52% of GMV in Q2 2026.

Future prospects matter as much as current results. The growth strategies below explain how Affirm Holdings, Inc. and Klarna Group plc each plan to expand from here.

Affirm Holdings, Inc. growth strategy: Affirm's disclosed growth priorities include increasing transaction frequency, expanding Affirm Card, adding merchants and platform integrations, entering additional markets, and maintaining diverse funding sources for originated loans.

Klarna Group plc 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. Revenue per active consumer rose 24% year over year in Q2 2026.
