Shares of Klarna rose 15% in their New York Stock Exchange debut Wednesday, closing at $45.82 after the Swedish fintech priced its IPO above its expected range.
Klarna, known for its popular buy now, pay later products, priced shares at $40 on Tuesday, raising $1.37 billion for the company and existing shareholders.
The IPO marks the latest in a growing list of high-profile tech listings this year, suggesting increased demand from Wall Street for new offerings. Companies like stablecoin issuer Circle and design software platform Figma soared in their respective debuts. Meanwhile, crypto exchange Gemini is expected to go public later this week.
"To me, it really just is a milestone," Klarna's co-founder and CEO Sebastian Siemiatkowski told CNBC in an interview on Wednesday. "It's a little bit like a wedding. You prepare so much and you plan for it and it's a big party. But in the end — marriage goes on."
The stock opened at $52 before dropping as the day progressed. At the close, the company was valued at about $17.3 billion.
Klarna's entry into the public markets will test Wall Street's excitement about the direction of its business. The company has in recent months talked up its move into banking, rolling out a debit card and personal deposit accounts in the U.S.
Klarna has signed 700,000 card customers in the U.S. so far and has 5 million people on a waiting list seeking access to the product, Siemiatkowski told CNBC. He added that Klarna Card represents a different proposition to rival fintech Affirm's card offering, which has attracted 2 million users since its launch in 2021.
"We're attracting a slightly different audience maybe than the Affirm card," Siemiatkowski said. "I get the impression that is more a card where people use it simply to be able to have financing with interest on slightly higher tickets."
In addition to Affirm, Klarna also competes with Afterpay, which was acquired for $29 billion in 2021 by Square, now a unit of Block.
Klarna faces some potential regulatory headwinds. In the U.K., the government has proposed new rules to bring BNPL loans under formal oversight to address affordability concerns regarding the market.
The IPO is poised to generate billions of dollars in returns for some of Klarna's long-time investors. Existing shareholders are offering the bulk of Klarna shares — 28.8 million — on the public market. At its IPO price of $40, that translates to almost $1.2 billion. Meanwhile, Klarna raised $222 million from the IPO.
Sequoia, which first backed Klarna in 2010, has invested $500 million in total. The venture firm sold 2 million of its 79 million shares in the IPO, meaning it's generated an overall return of about $2.65 billion, based on the offer price.
Andrew Reed, a partner at Sequoia, told CNBC that he was still in college when the firm made its first investment in an "alternative payments company in Stockholm." The early work, he said, was around expanding in Europe.
"Being here in New York 15 years later with over 100 million consumers and over $100 billion of GMV [gross merchandise value] and close to a million merchants, it is staggering what one year after another of execution and growth and Sebastian's long-term vision can do," Reed said.
Another Klarna investor hasn't been so lucky. Japan's SoftBank led a 2021 funding round in Klarna at a $46 billion valuation and has since seen the value of its stake plunge significantly.
