Klarna’s first quarter as a US-listed company landed harder than the market had priced. The Swedish Buy Now, Pay Later (BNPL) operator (NYSE: KLAR) booked $1.012 billion in Q1 2026 revenue, up 44% year-on-year, and turned net income positive at $1 million — but the consequential number is the one that ought to worry Visa, Mastercard and every traditional issuer: consumer deposits now fund 91% of Klarna’s lending book, the cheapest funding stack any pure-play BNPL has ever assembled. Having tracked European BNPL accounting since 2018, this is the quarter Klarna stopped being a BNPL company in any meaningful sense and started being a deposit-funded, stablecoin-curious bank that happens to lead with instalment loans.

The result, reported May 14, 2026, beat the high end of consensus on revenue, transaction margin and adjusted operating profit. Gross merchandise volume reached $33.7 billion (up 33% YoY) and adjusted operating profit climbed to $68 million from $3 million a year earlier — a 14x compression of cost-to-revenue the CFO called out explicitly.

Why the deposit story is the story

Klarna’s December 2025 IPO prospectus already disclosed $14 billion in deposits as the dominant funding mix. The Q1 update extends that into a 91% reading — a level no BNPL peer reaches. Affirm relies primarily on warehouse facilities, securitisations and ABS markets; PayPal’s “Pay in 4” sits on its own balance sheet without warehousing retail deposits at scale; Klarna’s European BNPL competitors operate under e-money licences that explicitly cannot accept savings deposits. That divergence in cost-of-funds is what makes head-to-head comparison with credit cards real for the first time, particularly at Klarna’s 270-day average deposit duration — a tenor mismatch favourable to a six-week BNPL book.

“This quarter was a good quarter. We delivered above the high end of every line,” said Sebastian Siemiatkowski, Chief Executive Officer at Klarna, on the May 14, 2026 earnings call. (The Globe and Mail)

How competitors and card networks have responded

Worldline has already moved to capture distribution rather than fight Klarna head-on. The Paris-headquartered acquirer signed a framework agreement on May 22, 2026 to deploy Klarna’s BNPL inside its European merchant network — see our Klarna–Worldline framework breakdown. PayPal extended Pay in 4 to merchant-funded variable terms in late April, sacrificing margin to defend share. Affirm responded with longer-duration 0% APR funded products to bank partners. Mastercard’s Installments Connect saw a Q1 2026 uptick in usage, but card-network economics remain pinned to interchange that BNPL operators bypass on push-to-debit rails.

“Transaction margin dollars are growing more than 14x faster than our cost base,” said Niclas Neglén, Chief Financial Officer at Klarna, on the same call. (The Globe and Mail)

The stablecoin pivot is the second-derivative bet

KlarnaUSD — the dollar-pegged stablecoin Klarna is launching on Tempo, the EVM-compatible chain co-developed by Stripe and Paradigm — is not yet revenue. It is the clearest read on where the cash Klarna’s deposit base now produces is being deployed. Built using Open Issuance by Bridge, KlarnaUSD targets cross-border merchant payouts. Cross-border B2B payment volume sits at roughly $120 billion a year on Klarna’s own estimates; capturing even single-digit share would cover most of the current EBITDA contribution from European card-not-present fees. This is also how Klarna closes the loop with US deposit-funded fintechs like Mercury, which just cleared an OCC national bank charter, and stablecoin-native challengers like Fasset, whose $51 million Series B formalised the rails-on-stablecoin neobank model.

What this means for the European fintech operator class

The Q1 print sets a yardstick European peers will struggle to match. Revolut (private) reports 68.3 million customers and £4.5 billion 2025 revenue but does not break out deposit-funding share of lending; Monzo’s £16.6 billion deposit base maps to a £113.9 million 2025 profit with no BNPL exposure of comparable size. Klarna’s $1 billion revenue quarter at 91% deposit-funded lending is therefore the cleanest demonstration to date that a BNPL franchise can graduate into the deposit-bank model without an acquisition. Expect Affirm to attempt a US chartered-bank route within two to three quarters and PayPal to lean harder on stablecoin payouts to defend cross-border margin. The cost-of-capital advantage is structural, not cyclical — and the next wave of fintech IPO prospectuses will talk about funding mix and deposit duration the way 2020-vintage prospectuses talked about take-rate.
