A Race to the Public Markets
Klarna’s push toward a U.S. IPO has done something that months of fintech headlines could not: it has forced a direct comparison between the Swedish buy now, pay later giant and Affirm, its publicly traded American rival. With Klarna filing its S-1 and targeting a valuation that would make it one of the larger tech listings of the year, investors are now holding both companies side by side and asking an uncomfortable question – which one actually has the better business?
For Affirm, the timing is awkward. The company has spent the past two years rebuilding credibility with Wall Street after a brutal post-2021 selloff that wiped out most of its market cap. It has diversified its merchant relationships, leaned harder into its Debit+ card product, and pushed profitability timelines aggressively. Now, right as that story was gaining traction, Klarna walks in with an IPO roadshow narrative that tells a very similar story – but with a European consumer base, a broader product suite, and a valuation argument that could pull institutional capital sideways.
What Klarna’s Filing Actually Says to Affirm Shareholders
Klarna’s S-1 presents the company as more than a BNPL lender. It describes a shopping ecosystem: an app used by tens of millions of consumers not just to split payments but to browse products, receive personalized offers, and manage purchases. That framing is intentional. It positions Klarna closer to a commerce platform than a credit product, which typically commands a higher valuation multiple. Affirm has made similar arguments about its role in the consumer purchase journey, but Klarna’s filing gives institutional investors a fresh data set to benchmark against – and some of those benchmarks are not flattering for Affirm.
Klarna reported a return to profitability in 2023, a milestone it leaned on heavily in its pre-IPO communications. Affirm, by contrast, is still working toward GAAP profitability, operating on adjusted metrics that sophisticated investors have grown increasingly skeptical of across the fintech sector. The gap matters less as an accounting detail and more as a perception problem – when a direct competitor shows up to the public markets with a cleaner income statement, it raises the standard against which Affirm’s own trajectory gets measured.
There is also a geographic story at play. Klarna operates across more than 45 countries, giving it a diversification argument that Affirm, which remains heavily concentrated in the U.S. market, cannot easily match. For large institutional funds building fintech exposure, Klarna’s listing offers a way to buy into the BNPL trend with built-in international spread. That is not an argument against Affirm specifically, but it does reduce the urgency to hold Affirm as the primary vehicle for that thesis.
Affirm’s stock has historically moved on macro signals – interest rate expectations, consumer credit health data, and its relationship with major merchant partners. Those fundamentals have not changed. But IPO moments create gravitational pulls in investor attention that can temporarily distort how existing public company stocks are perceived, and Affirm is currently sitting directly in that pull.
Merchant Relationships and the Competitive Overlap Problem
One of the sharpest edges of the Klarna-Affirm rivalry is merchant overlap. Both companies have pursued relationships with major U.S. retailers, and as Klarna accelerates its American expansion alongside its IPO push, the competition for checkout placement is becoming more direct. Affirm has historically differentiated on larger-ticket purchases – furniture, electronics, travel – where consumers want longer repayment terms. Klarna built its early U.S. brand around fashion and everyday retail, with shorter pay-in-four structures. That distinction is eroding as both companies push toward each other’s territory.
Klarna’s reported U.S. merchant count has grown significantly over the past two years, and its IPO capital, once raised, will almost certainly fund a more aggressive push into categories where Affirm has held stronger ground. The merchant that offers both checkout options does not necessarily maintain a preferred partner – they optimize for conversion rates and consumer preference, which shifts. Affirm’s integration depth with certain key retail partners remains a genuine competitive advantage, but it is not a permanent moat if Klarna is willing to spend to replicate it.
Investor Confidence: What’s Actually Wobbling
Affirm’s investor confidence is not collapsing – the company’s stock has shown resilience and its underlying credit metrics have largely held up through a high-rate environment that punished many consumer lenders more severely. The concern is subtler: it is about narrative displacement. When a category competitor files for IPO with a compelling public story, the existing public company in that space sometimes finds its own story suddenly feels less fresh, less exciting, or less differentiated to the institutional investors who are being pitched the new deal.
There is also a capital rotation dynamic worth watching. Growth-focused funds that already hold Affirm may look at a Klarna IPO allocation as an opportunity to adjust their fintech exposure rather than simply add to it. That does not guarantee selling pressure on Affirm, but it introduces a new variable in the positioning calculus that did not exist six months ago. Portfolio managers running concentrated fintech bets rarely want two highly correlated positions in the same subsector when one of them just got a fresh story to tell.
What makes this moment genuinely interesting for Affirm is that the company has actual leverage it has not fully used yet. Its partnership with Apple for installment lending at Apple Pay checkout remains an underexplored growth surface. Its Debit+ card product has a real behavioral hook – consumers who use it are spending more frequently and in more categories than traditional BNPL users. These are not cosmetic features – they are structural arguments for why Affirm’s unit economics could improve materially over the next two years, independent of whatever Klarna does in the public markets.
The question Affirm’s leadership now has to answer is whether those growth levers can be communicated clearly enough, and quickly enough, to hold institutional attention during a period when the fintech IPO window is reopening and newer narratives are competing for the same dollars. Klarna’s IPO does not define Affirm’s fate – but it does set a new baseline for what investors expect a mature BNPL company to look like, and Affirm will be measured against it whether the company wants that comparison or not.
