Klarna Becoming a Commerce Operating System

The real prize in Klarna is not the loan, it is owning the shopping session often enough to become the layer that sees demand, routes payment, sells ads, and prices risk. Once Klarna gets consumers to start in its app instead of meeting it only at checkout, it stops being paid only for fronting short term credit and starts monetizing the whole purchase flow, from discovery and rewards to debit, ads, and underwriting data.

• Klarna has already started this shift. In 2024, merchant BNPL fees were 57% of revenue, down from 75% in 2020, while ads reached $180M, interest bearing loans $675M, late fees $254M, and card interchange $84M. That is what a multi line consumer fintech looks like, not a single product lender.

• The app matters because it gives Klarna first party shopping data and cheaper distribution. Klarna’s shopping app was doing about $10B in annual GMV by 2024, and its merchant base lets it offer rewards and debit based pay by bank options that can pull volume away from cards and improve merchant economics.

• This is also how Klarna diverges from Affirm and starts to resemble PayPal or Cash App. Affirm is a higher ticket lender with roughly $120 ARPU tied to large purchases, while Klarna runs closer to a roughly $30 ARPU consumer app built around frequent, sub $100 shopping moments and repeat engagement.

If Klarna keeps increasing purchase frequency and pushing more transactions through its own consumer surfaces, the next step is a closed loop shopping and payments network. That would make Klarna look less like a lender attached to checkout and more like a commerce operating system that merchants pay for distribution, conversion, payment routing, and customer acquisition.
