Klarna Unbundles Merchant Funded Rewards
Klarna: The $31B Snapchat of Personal Banking
Klarna turned rewards from a balance sheet subsidy into a merchant funded growth channel. A credit card usually pays points from interchange and interest, then spreads those rewards across broad categories. Klarna instead plugs merchants directly into the offer engine, so a shopper opens the app, sees specific stores, gets 5% to 10% cash back, and pays over time, while the merchant funds the economics because Klarna can show more conversion and repeat purchase.

For merchants, the product is not just financing. Klarna pays the retailer upfront, charges roughly 3% to 6%, takes fraud and chargeback risk, and can point to whether baskets using Klarna convert better, sell through at full price faster, or bring the shopper back again.
-
For consumers, Klarna keeps the part of cards people like, flexible payment timing and store specific rewards, while dropping the revolving balance habit that made traditional cards so profitable. That fit a younger, debit first shopper who wanted spending control but still wanted help covering a $280 to $380 basket.

The model has stayed durable because Klarna kept building the closed loop around shopping. In 2024, core BNPL merchant fees were still $1.6B, or 57% of revenue, but Klarna had added $180M of merchant ads and a shopping app built around cash back discovery, making it look more like a demand generation network than a plain lender.
The next step is deeper control of shopping before checkout. As more BNPL buttons become interchangeable, the winners will be the ones that bring merchants incremental demand, personalize offers inside the app, and turn payments into an advertising and commerce network. Klarna is already moving in that direction, with merchant fees, ads, cards, and subscriptions all reinforcing the same loop.
