Klarna was profitable in Q3, according to their press release. I cannot find their actual report on their investor relations site, but to me it seems like it was driven by strong revenue growth of 30 % year-over-year (up from 15-20 % earlier in 2023) combined with lower credit losses.
Klarna also has registered a holding company in the UK according to reports. But if they IPO in the UK instead of the US or Sweden, I’d wonder what the board of directors have been drinking or smoking.
