Klarna provides online payment solutions that let shoppers buy now and pay later for purchases made in e-commerce. Its service enables customers to complete purchases immediately and defer payment to a later date, often with no interest if paid within a set period. It earns money by charging merchants a transaction fee and by offering extended payment plans that may include interest or fees. Klarna operates in markets across Europe, North America, and the Asia Pacific region, serving both individual consumers and online merchants. Its goal is to facilitate smoother transactions between shoppers and merchants by offering flexible payment options that can boost merchant sales and improve the shopping experience, while maintaining transparency about system status and reliability.

↓ -1%Klarna's attempt to replace 700 customer service agents with AI backfired spectacularly, forcing the Swedish fintech company to reverse course and adopt a hybrid approach. When the AI assistant went live in late 2024, customer satisfaction plummeted as quality scores tanked. Recent data from Prosper Insights & Analytics shows 63% of Gen-Zers hadn't heard of agentic AI, whilst over 36% of surveyed consumers don't believe it's a good idea. Klarna CEO Sebastian Siemiatkowski admitted cost considerations led to lower quality service. The company now combines AI for simpler tasks with human agents for complex issues, with Siemiatkowski emphasising customers should always have the option to speak to humans. The experience reflects broader industry challenges, with PwC reporting 56% of CEOs see neither revenue nor cost benefits from AI investments.

Klarna, the global digital bank and flexible payments provider, today doubled its existing forward-flow and whole-loan sale agreement with investment funds managed by Elliott Investment Management. The facility size doubles to $2bn and the term extends by one year to three years, enabling Klarna to facilitate up to $17bn-worth of US Financing loans during the remaining life of the program. "Klarna's US Financing is growing fast because it gives Americans something the credit card industry never has: real choice, clear terms, and no surprises. This partnership sets the foundation for us to meet the accelerating demands of our American consumers." — Niclas Neglen, Chief Financial Officer, Klarna The upsizing reflects the strong performance of the program since the two companies first announced their partnership in November 2025. In Q4 2025, Klarna's US Financing GMV grew significantly, and the expanded facility gives Klarna further capacity to support the accelerated demand. Under the
Klarna has raised $1.7 billion through a significant risk transfer transaction with a consortium led by Värde Partners, its largest such deal, designed to support up to $40 billion in lending capacity. Combined with a $2 billion facility announced in March with Elliott Investment Management, the deals provide substantial capital relief for the Swedish buy-now-pay-later company. The moves come as Klarna's shares have fallen 76% from their September IPO price of $40 to roughly $12. Despite the stock decline, the company reported strong operational performance, with full-year 2025 revenue reaching $3.5 billion, up 25%, and US revenue growing 58% year-on-year in Q4. The SRT structure allows Klarna to transfer credit risk to third-party investors whilst maintaining its banking licence advantages, freeing capital for growth without proportionally expanding its balance sheet.
