Swedish fintech Klarna made a strong debut on the New York Stock Exchange, raising $1.37 billion and valuing the company at $15 billion, underscoring the booming buy-now, pay-later (BNPL) sector. While Klarna’s growth is fueled by expanding user base and partnerships, experts caution about mounting consumer risks, including financial overextension and the upcoming impact of BNPL activities on credit scores. Klarna’s strategy aims to capture millennial and Gen Z shoppers, positioning BNPL as a mainstream payment alternative despite increasing regulatory and financial scrutiny.
