Klarna's $17.4 Billion NYSE Debut Caps a 20-Year Run

Klarna raised roughly $1.37 billion on September 10, 2025, selling 34.3 million shares at $40 each on the New York Stock Exchange under the ticker KLAR. The offering valued the buy-now-pay-later pioneer at approximately $17.4 billion, and the stock closed its first session around $45 — a gain of about 15% over the IPO price after trading above $50 intraday.

The listing is the latest milestone in a two-decade arc that began at the Stockholm School of Economics. In 2005, students Sebastian Siemiatkowski, Niklas Adalberth and Victor Jacobsson entered their school's annual entrepreneurship contest with a simple goal: make online payments easier. That idea became Kreditor, the company that rebranded as Klarna in 2009.

Growth came fast once the model found its footing. The company signed its 1,000th vendor in 2007, pushed into Denmark, Finland and Norway in 2008, and rolled out installment payment solutions and Klarna Checkout in the years that followed. A 2013 acquisition of SOFORT deepened its European footprint. By 2014, Klarna held a 10% share of the Northern European market and processed 30% of all online sales in Sweden — meaning nearly one in three krona spent online in its home country moved through its rails.

What does Klarna actually sell?

The company's mantra is "smooth shopping," and it expresses that through payment flexibility. Shoppers can pay directly, pay after delivery, or split purchases into installments under the flagship Pay In 4 program. A one-click purchase experience ties it together, whether customers use Klarna's own app or check out through partner retailers, online and in-store. Its main rivals in the space are Block, Affirm and PayPal.

That investor roster is worth noting too. Sequoia, Visa, Atomico and Bestseller all back the company — a lineup that gave Klarna credibility well before its public debut.

The comeback nobody should overlook

The IPO looks very different against Klarna's recent history. The company took a sharp valuation hit in 2022, a period when rising rates battered the entire BNPL category. The recovery since then is measurable: revenue climbed to $2.81 billion in 2024 from $2.28 billion in 2023 — growth of roughly 23%, or about $530 million in a single year. More importantly, Klarna swung from a net loss of $244 million in 2023 to profitability in 2024.

CEO and co-founder Sebastian Siemiatkowski framed the turnaround in the company's Q3 2024 report: "We're back in familiar territory: profit and growth, just like the old days. With our exciting new collaborations with Worldpay, Apple Pay, Google Pay and Adyen, we're closer than ever to making Klarna available at every checkout."

That quote matters more than the usual earnings-season rhetoric. The partnerships with Worldpay, Apple Pay, Google Pay and Adyen are distribution deals — they put Klarna's payment options in front of shoppers at checkout points it could never reach through direct merchant sales alone.

What does this change for practitioners?

For merchants and payments professionals, a public Klarna means more transparency: quarterly filings will expose the unit economics of BNPL for the first time in this category at this scale. For competitors like Affirm, Block and PayPal, the bar is now a profitable, publicly traded rival with $2.8 billion in revenue and expansion ambitions at, as Siemiatkowski puts it, every checkout.

Siemiatkowski, who also founded the Swedish investment company Flat Capital, now leads a company that has traveled from a student contest entry to a household name in digital payments. The 2025 IPO opens its next chapter in the public markets, where Klarna will have to keep proving that profit and growth can coexist — something it managed in 2024 but hasn't yet sustained across a full market cycle.
