When Klarna filed its S-1 in late 2024 and finally went public on the NYSE in July 2025 at a $15 billion valuation — a far cry from its $45.6 billion peak — most ecommerce observers read the moment as a reckoning. The BNPL bubble had deflated. Affirm was trading sideways. Afterpay had been quietly digested into Block’s ecosystem. The era of frictionless installment payments as a growth engine seemed to be fading.
But Klarna CEO Sebastian Siemiatkowski had other plans. By Q1 2026, Klarna was no longer pitching merchants primarily on conversion lift from split payments. It was pitching something harder to categorize — and, depending on who you ask, harder to resist or harder to trust.
What Is Klarna Actually Selling Merchants in 2026?
The short answer: checkout ownership, shopping discovery, and AI-powered personalization, all bundled around a payment rail that 85 million U.S. consumers already have on their phones.
Klarna’s merchant-facing product suite in 2026 has expanded well beyond its core installment offering. The company now operates:
- Klarna Checkout — a one-click checkout layer that competes directly with Shop Pay, not just PayPal. Merchants who adopt it hand over the full checkout UX to Klarna’s interface.
- Klarna Shopping App — a consumer-facing discovery and price-comparison tool with 37 million monthly active U.S. users as of March 2026, per Klarna’s investor day deck.
- Klarna Ads — a retail media network that lets merchants buy sponsored placements inside the shopping app, positioned as a lower-CPM alternative to Amazon Sponsored Products for non-endemic brands.
- Klarna AI Assistant — a conversational shopping tool embedded into the app that fields product queries and routes users to merchant listings, powered by a partnership with Anthropic announced in February 2026.
The bundling logic is clear: each product deepens Klarna’s position in the consumer’s shopping journey, from discovery through checkout, generating data that reinforces the next transaction.
“We’re not a payments company anymore in the way people defined that term five years ago. We’re the operating system for how a consumer decides, discovers, and buys — and merchants who figure that out early are seeing meaningful ROAS from the ads product alone.” — Sebastian Siemiatkowski, Klarna CEO, at Shoptalk Spring 2026
How Does Klarna’s Checkout Layer Stack Up Against Shop Pay?
This is where the competitive picture gets complicated for Shopify merchants specifically. Shop Pay processed an estimated $130 billion in GMV globally in 2025, according to Shopify’s annual report. It’s deeply embedded in Shopify’s checkout extensibility framework, benefits from one-tap autofill for tens of millions of buyers, and carries near-zero friction for merchants already on the platform.
Klarna Checkout, by contrast, requires more integration lift and — critically — asks merchants to cede more UX control. Merchants on Shopify can install Klarna as a payment method without adopting Klarna Checkout, but the full-funnel pitch requires the latter.
Liz Donahue, head of partnerships at a New York-based Shopify Plus agency that manages roughly $200 million in client GMV annually, put it bluntly:
“Our Shopify Plus clients aren’t replacing Shop Pay with Klarna Checkout. What we’re actually seeing is brands layering Klarna Ads as a new acquisition channel — that’s where the budget conversation is happening, not at the checkout infrastructure level.”
That tracks with publicly available data. Klarna reported 18,000 active merchants on its ads platform in Q4 2025, up from roughly 4,000 a year prior. For DTC brands in categories like home goods, beauty, and apparel — where Klarna’s consumer base skews heavily — the shopping app is increasingly a legitimate media buy.
Is Klarna’s Retail Media Network a Real Threat to Amazon Ads?
Not yet — and perhaps never at scale for most Amazon-native sellers. But for DTC brands that have found Amazon’s ad auction increasingly punishing in 2026, Klarna Ads is an interesting secondary channel.
The pitch is essentially: Klarna’s shopping app users are in-market by definition. They’ve opened a price-comparison tool because they intend to buy something. CPMs on Klarna Ads reportedly run between $4 and $9 for most apparel and home categories, compared to effective CPMs of $18–$35 for comparable placements on Amazon’s sponsored product auctions in competitive segments, per data shared by agency Tinuiti in its Q1 2026 retail media benchmark report.
The caveats are real, though. Klarna’s attribution model is last-click by default, which inflates its reported ROAS. The shopping app’s search volume is a fraction of Amazon’s. And unlike Amazon’s DSP, Klarna has no off-platform retargeting capability yet.
Marcus Chen, director of growth at a $40M DTC home goods brand that has been running Klarna Ads since Q3 2025, described the results as “genuinely interesting but not transformative.”
“We’re spending about $15K a month on Klarna Ads and seeing a reported 4.2x ROAS — but we know some of that is people who would have bought anyway. As a prospecting channel for a specific income bracket of consumer, it’s working. It’s not replacing our Meta spend.”
What Are the Real Risks for Merchants Who Go Deep With Klarna?
Several concerns circulate among operators and agency leaders who work with Klarna at scale.
Data ownership ambiguity. Merchants who adopt Klarna Checkout share transactional and behavioral data with Klarna, which uses it to optimize the shopping app and its ads platform. Klarna’s updated merchant agreement, revised in January 2026, gives it broad latitude to use anonymized purchase data for product improvement — language that makes some legal teams nervous.
Consumer credit risk exposure. Klarna’s BNPL originations remain its core revenue driver, and its U.S. delinquency rate ticked up to 3.8% in Q4 2025, per its earnings release. Merchants get paid regardless of consumer repayment — that risk stays with Klarna — but in a macroeconomic downturn, Klarna’s underwriting could tighten, reducing approval rates and converting fewer BNPL sessions into completed orders.
Competitive checkout pressure. PayPal is not sitting still. PayPal’s Fastlane product, which enables guest checkout autofill across any merchant, processed over $20 billion in GMV in 2025 according to its Q4 earnings call. Apple Pay continues to expand its merchant footprint. For merchants debating where to invest checkout optimization resources, the number of credible alternatives makes exclusive bets on any single provider risky.
Pricing volatility. Klarna’s merchant discount rates — the percentage of each transaction it takes — have crept upward since its IPO. Multiple agency sources confirmed MDRs in the 3.5%–5.9% range depending on merchant size and payment plan type, up from 2.9%–5.5% ranges quoted in 2023. For high-AOV merchants, this matters.
How Is Klarna’s AI Strategy Playing Out for Ecommerce?
The Anthropic partnership is the most substantive AI move Klarna has made, and it’s early but directionally important. The Klarna AI Assistant, now embedded in the shopping app and accessible via a widget on participating merchant sites, can handle natural language queries like “find me a sofa under $800 that ships in two weeks” and return merchant-specific results with Klarna payment options surfaced inline.
For merchants, this is essentially an AI-powered product discovery layer that can surface their catalog to high-intent consumers — but only if their product feed is optimized for Klarna’s indexing. Merchants using the Klarna Merchant Portal can now submit structured product data including availability, shipping timelines, and return policies to improve AI Assistant match rates. Think of it as a Klarna-specific SEO task.
Industry analyst Andrew Lipsman, who covers retail media and commerce platforms, noted in his April 2026 substack that Klarna’s AI layer could become a meaningful differentiator if it reaches sufficient scale:
“The question isn’t whether Klarna’s AI shopping assistant is technically impressive — it is. The question is whether 37 million monthly actives is enough to make optimizing for it a priority for a merchant with limited product and marketing bandwidth. For most brands, the answer right now is still no.”
Should Shopify and Amazon Sellers Be Paying Closer Attention to Klarna?
The honest answer is: it depends on your category and customer profile.
For Shopify merchants in fashion, beauty, home, and electronics — categories where Klarna’s U.S. consumer base is most concentrated — the ads platform is worth a test budget of $10K–$20K per quarter to evaluate incrementality properly. Use a geo-holdout or a Northbeam or Rockerbox attribution layer to strip out the last-click inflation before declaring a winner.
For Amazon-native sellers, Klarna is largely irrelevant to current operations. Its checkout layer doesn’t touch the Amazon marketplace, and its shopping app is not a meaningful source of Amazon traffic. The one exception: brands running DTC sites alongside their Amazon presence who want a broader top-of-funnel media mix.
For Shopify Plus merchants evaluating checkout infrastructure, the advice from most agency operators is consistent: don’t replace Shop Pay with Klarna Checkout unless you have a specific, documented reason — such as a customer base that heavily uses Klarna’s consumer app. The integration complexity rarely pays for itself.
What Klarna has built in 2026 is genuinely interesting: a consumer shopping platform with real monetization potential for the right merchant profile. But it is not yet the unified commerce OS Siemiatkowski describes on investor calls. The gap between the vision and the merchant reality remains wide, and closing it will require Klarna to prove that its data flywheel produces measurably better outcomes than the platforms merchants are already committed to.
That proof is still mostly forthcoming.
