"The new valuation represents a 47.3% increase over Klarna’s post-money valuation of $31 billion in early March, when it raised $1 billion, and a 330% increase over its $10.6 billion valuation at the time of its $650 million raise last September."
"Overall, Klarna is live in 20 markets, has more than 90 million global active users and more than 2 million transactions a day conducted on its platform. The company’s momentum can be seen in its impressive financial results. In the first quarter, Klarna notched $18.1 billion in volume compared to $9.9 billion in the prior year first quarter. In all of 2020, it processed $53 billion in volume. To put that into context; Affirm’s financial report in May projected it would process $8.04 billion in volume for the entire fiscal year of 2021 and Afterpay is projecting $16 billion in volume for its entire fiscal year."
Klarna's valuation is higher, however it has exploded above APT only recently. It is also significantly larger, in customers and transaction value. At APT first half numbers, Klarna has 7x as many customers (90m / 13m), and 4.5x annualised transaction value. Relative valuation can also be dangerous if what you are comparing to is also inflated. But to answer your queation, Klarna is signifiantly larger that APT and its latest funding round gives it alot of firepower to acquire more customers.
